There are 3 ways through which a contrast is administered, and they have been briefly mentioned below: ☛ Intravenous CT Scan Contrast. Intravenous contrast is injected into the body to highlight the organs, such as brain, spine, liver, and kidneys. An iodine contrast agent is mostly used for an intravenous injection.
One of the most dangerous things that can happen to a patient during a CT scan is an anaphylactic reaction to the iodine in the contrast agent. In hypersensitive patients, the iodinated contrast medium can cause a plunge in blood pressure (hypotension), a histamine response, and a cascade of deadly events that causes the airway to swell shut.
• Moderate reaction: About 1% of patients experience severe vomiting, swelling, and hives. • Severe reaction: About 0.1% of patients experience life-threatening anaphylaxis. One of the most dangerous things that can happen to a patient during a CT scan is an anaphylactic reaction to the iodine in the contrast agent.
If you had a CT scan that failed to find the presence of lung cancer, or if a CT scan wrongfully diagnosed an abnormality as cancer, you may be able to sue for your damages. If a health care provider’s negligence caused you to suffer physical, emotional, or financial harm, you might have grounds for a civil lawsuit.

Once a patient has a bad reaction to an iodine contrast agent, it’s important that the healthcare team recognize it quickly, obtain a medical diagnosis, and institute appropriate treatment.
Some patients, though, have a more intense reaction that can range from mild to deadly. When an iodinated contrast is administered by IV, 5-8% of patients have a reaction. These reactions can be:
A contrast agent is a dye-like substance that’s given to a patient through an intravenous (IV) line or to orally swallow, which will help the radiologist see structures more clearly on an MRI or CT scan. Ordering some studies with contrast improves their diagnostic reliability.

No one expects to die from a CT scan, but that’s exactly what can happen if a facility is unprepar ed and physicians and staff aren ’t paying attention. The standard of care requires healthcare providers to monitor patients for signs of an iodine reaction or anaphylaxis and to take prompt steps if there’s a problem.
Both CT and MRI scans can be ordered with or without contrast. Based on my experience as a former hospital administrator and a long-time Texas medical malpractice attorney, there are some important considerations about CT contrast agents that I think every patient should be aware of.
Contrast helps enhance certain body structures. Almost always, CTs should be ordered with or without contrast, not both. Here is an overview of the indications for contrasted CT:
There are several contrast agents that may be used in performing CT scans. The most common are baruim and iodine based. These agents for enhancing the image created on CT may be delivered by a number of different routes, the most common of which are oral and intravenous.
IV contrast may be used to visualize vasculature as well as the internal organs of the abdomen and pelvis. Renal function should be assessed with a baseline creatinine level before administration as patients with impaired renal function are at risk for complications associated with IV contrast.
CT Angiography, or CTA, is a type of contrasted CT scan used to evaluate the blood vessels. Below is an overview of the following CTA studies and their indications:
Oral contrast is generally used for visualization of the abdomen and/or pelvis when there is suspicion of bowel pathology. These agents are not used for imaging of the abdomen and/or pelvis if bowel pathology is not suspected, or if doing so will delay scanning as in the case of acute trauma.
If you’re ever stuck when it comes to the correct diagnostic imaging method for your patient, pick up the phone and call the radiologist or imaging facility with whom you work. These experts are usually happy to help select the correct test for your patient.
Indications for Non-contrast CT. Contrast is not used in patients with head, extremity or spine trauma. It is also not used in patients with suspected acute stroke. Finally, imaging of the abdomen and pelvis to assess for renal stones also does not require CT contrast.
Meanwhile, a general CT of the chest with IV contrast will have the contrast timed so that it is present within the capillary bed of the soft tissues. For the abdomen and pelvis, contrast timing is more complicated, because there are both systemic and portal venous capillary beds. Most CT scans of the abdomen and pelvis are timed ...
In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest. For instance, a CT angiogram of the chest to evaluate for PE will have the timing set so the contrast is present in the pulmonary arteries.
There are three broad kinds of contrast available: IV, PO, and PR (rectal). IV contrast is either gadolinium for MRI or iodinated contrast for CT. PO contrast for all ER and inpatient CT scans is dilute iodinated contrast (same agent used for IV contrast in CT). Barium is available as an alternative for ER patients with allergic reactions to iodinated contrast agents; currently the Department of Radiology recommends premedication for PO iodinated contrast in patients with a history of moderate or severe allergy (see departmental policy ). Rectal contrast like oral contrast is dilute iodinated contrast, but administered through a rectal tube.
The most commonly used MRI contrast agent in YNHHS is a macrocyclic agent for which the risk of NSF is thought to be extremely low, if present at all (even in patients on dialysis or with acute renal failure). For current policy on receiving gadolinium based agents click here. Gandolinium Contrast Information.
Generally, there is a 45-60 minute delay after finishing PO contrast before performing the CT study.
IV contrast is used in brain CT when performing a CT angiogram (or venogram) or for evaluating an abscess or malignancy. In general, workups start with a non-contrast brain CT study and then may progress to MRI or contrast enhanced CT when necessary.
Barium is available as an alternative for ER patients with allergic reactions to iodinated contrast agents; currently the Department of Radiology recommends premedication for PO iodinated contrast in patients with a history of moderate or severe allergy (see departmental policy ).
There were 6,954 patients in the contrast group vs. 909 patients in the non-contrast cohort. Every patient receiving an abdominal or chest CT during the six-year period fulfilling the admission criteria was included. The contrast and non-contrast groups did not differ in any parameter examined (Table 1). The age of both groups was nearly identical (both mean 54 years with std dev. 19.4 yr vs. 18.1 yr respectively). The contrast group was 57%/43% female to male compared with a 53%/47% ratio in the controls. Likewise, there was no significant difference in the incidence of diabetes in the two groups. For the primary outcomes of clinically significant adverse events, see Table 2. There were 106 deaths in the 6,954 patient contrast group versus 11 deaths in the 909 patient control group (1.5%, 95% CI [1.5%–1.8%] vs. 1.3%, 95% CI [0.7%–2.3%]; p=0.24). There were 16 patients in the contrast group (0.23%, 95% CI [0.1–0.4]) who required dialysis versus none in the non-contrast controls (95% CI [0.0%–0.3%], p=0.14). Regarding the incidence of what is traditionally termed “CIN” (defined as an increase of 25% or more within 96 hours of admission, but in this case regardless whether contrast was actually administered) 598 of 6,954 (8.6%, 95% CI [0.8%–9.3%]) receiving contrast met this criterion compared with 87 of 909 (9.6%, 95% CI [0.078–0.117]) patients not receiving contrast (p=0.32) (Table 2).
It is difficult to establish whether the contrast group was inherently a “sicker” group than the non-contrast controls, but it does not appear there were major differences. To be included, both groups were admitted to the hospital as inpatients. Mean length of stay for the contrast group was 5.3 days vs. 5.0 days in the non-contrast controls (p>0.75). Five hundred seventy-nine of 6,954 patients receiving contrast had any time in the intensive care unit (ICU) (8.3%) vs. 70 of 909 patients not receiving contrast (7.7%, p=0.39).
It has long been accepted that intravenous contrast used in both computed tomography (CT) and plain imaging carries a risk of nephropathy and renal failure, particularly in subpopulations thought to be at highest risk.1–3Although early studies used high osmolality contrast media that is not typical of emergency department (ED) use today, the issue of contrast-induced nephropathy (CIN) is still an area of active interest with many studies appearing each year from many different specialties, on its pathogenesis, incidence, prevention and treatment.4–7The plethora of data has usually focused on the incidence of CIN, usually defined as a small (such as 25% or an absolute increase of 0.5mg/dL) increase in creatinine after receiving intravenous (IV) contrast for either a particular indication (such as cardiac catheterization) or in a particular patient group (diabetics); the meaning of a creatinine rise in this setting is not at all clear, however.8–10Many regimens have been proposed to ameliorate this creatinine rise, but there is a scarcity of data on what actual adverse clinical events occur and whether these can truly be ascribed to the IV contrast itself rather than the events that might well occur in a (usually) hospitalized population that required imaging. A few authors have even expressed doubt as to whether modern iodinated contrast (which is iso-osmolal) is a nephrotoxin.11–13
Contrast CT Scans in the Emergency Department Do Not Increase Risk of Adverse Renal Outcomes
Our study’s most serious limitation is that the contrast and control groups are undoubtedly dissimilar in ways that are not captured by the parameters we measured, particularly age, gender and diabetic status. Although it might appear that since abdominal CTs without contrast are much more likely to be used in patients where less serious disease is suspected (for example, those with renal colic, which would make our results even more remarkable), it may be that patients with a creatinine less than 1.6mg/dL, being scanned without contrast, who are then admitted represent a subgroup of particularly ill patients, although this was not evident in our analysis of length of stay or ICU admission. Similarly, those receiving a chest CT without contrast (perhaps pneumonia or cancer) are not obviously a more or less morbid group than those who do receive contrast, which would include, for example, all those in whom pulmonary embolism is suspected.
In cases that end up in court, the most common claim is errors in diagnosis. Of those errors, the most frequently missed diagnoses involved breast cancer, lung cancer, and bone fractures. Radiologists are specially trained to interpret all kinds of diagnostic imaging, from x-rays to CT scans, from MRIs to angiograms.
The number one reason radiologists are sued is making the wrong diagnosis. February 22, 2019. by Robert Painter. Filed under: medical malpractice, radiology. Radiologists are the sixth most common type of physician to be sued in a medical malpractice case. In cases that end up in court, the most common claim is errors in diagnosis.
She chose not to recommend another scan because of a potential artifact concern.
It was a brain CT scan without contrast, and the only clinical information that was provided was “headache with dizziness and giddiness.”.
The real reason that the ER doctor ordered the brain CT scan was to see if there were signs of a stroke or some other cerebrovascular abnormality.
She repeatedly testified that she saw some “artifact,” but didn’t know at the time what it was. Artifact refers to a distorted image on a CT or MRI scan. It can be caused by the patient’s position or even slight movement. Part of the radiologist’s job is to distinguish artifact from real images.
One of the things that neuroradiologists are supposed to look for on the head CT is edema, or swelling. That’s a sign of trouble, and it could mean that the patient was suffering from a dissected cerebral blood vessel or even an early stroke.
There are 2 types of contrasts used, namely, barium sulfate (the most commonly used agent for a CT scan) and Gastrografin (sometimes used as a substitute for barium). ☛ Rectal CT Contrast. The rectal CT contrast is administered using an enema to enhance the images of the large intestine and lower gastrointestinal organs.
Speak to your doctor regarding all the procedural details, possible side effects, and precautions you need to take before undergoing a CT scan. Also, make sure you inform the doctor about any of your existing medical conditions, like diabetes, allergies, pregnancy, etc. Take care!
Intravenous contrast is injected into the body to highlight the organs, such as brain, spine, liver, and kidneys. An iodine contrast agent is mostly used for an intravenous injection. ☛ Oral CT Scan Contrast. One needs to drink the oral CT scan contrast to highlight the images of the abdomen and pelvis region.
One is suggested to undergo a CT scan to diagnose medical problems within the bones, organs, soft tissues, and blood vessels that are hard to detect using conventional diagnostic methods. A CT Scan with contrast, also called a CAT scan, is a noninvasive medical test. It is used to produce multiple images of the internal body organs ...
Contrast agents, also called dyes, are used to highlight the organs, blood vessels, tissues, etc. As these dyes are injected or administered within the body, it may sometimes lead to certain side effects. In the following paragraphs, we shall understand more about this procedure and the side effects associated with it so ...
Now, that you know the different contrast agents and the modes of their administration, we shall move on to the side effects. Although considered to be a safe and harmless diagnostic process, there are a few side effects of CT scan with contrast. It is always wise to know about these effects in order to seek immediate medical help if the need arises.
It is considered to be the safest contrast agent that does not cause any serious side effects. However, the person experiences a warm or flushed feeling upon being injected with this contrast. He/she may also experience a metallic taste in their mouth that lasts for about a minute or so.
A typical exam will take between 10 to 15 minutes.
If your exam requires an oral contrast, such as an abdominal scan, you will need to drink it a minimum of 1 hour prior to the start of the exam. This will allow the contrast to coat your stomach and small intestine. You may arrive early or pick up the contrast here at your convenience.
Yes. Since CT uses x-ray to acquire its images, it is safe for a person with a pacemaker to have a scan without complications. MRI, which uses a strong magnetic field to acquire images, could interfere with a pacemaker. If you have a pacemaker you should NOT go near the MRI machine.
Not everyone needs an injection of contrast for their exam. The injection is given when the radiologist and/or the referring physician determines that it is necessary. The decision to use contrast is based on the patient's history and the type of study to be performed.
No. Because CT uses x-ray to acquire the images, only the person having the exam should be in the room during the imaging. Friends or family can wait in our imaging suite while the scan is being performed.
When a CT Scan Is Wrong About Cancer. When a CT scan fails to detect the presence of cancer, it can mean a delay in treatment. According to the National Cancer Institute (NCI), the earlier cancer is diagnosed, the better the prognosis. Some lung cancers may be easier to treat in their early stages, and early diagnosis may mean treatment can begin ...
CT is short for computerized tomography. CT scans are sometimes referred to as CAT scans. Using CT scans, healthcare workers are able to obtain information about what is happening inside of the body without having to operate.
In cancer diagnoses, a CT scan can detect the presence of abnormal cell growth and pinpoint a tumor’s shape, size, and location.
This could be due to scanning errors or a misinterpretation of the scans by your oncologist. If either of these is the case, you could have legal options. Complete a Free Case Evaluation form now.
In cancer diagnoses, a CT scan can detect the presence of abnormal cell growth and pinpoint a tumor’s shape, size, and location. Doctors can use continued CT imaging to monitor a tumor’s growth, see if treatment is shrinking a tumor, or check for the recurrence of a tumor.
Health care professionals use CT scans as a diagnostic tool for multiple types of cancer, including lung cancer. However, a CT scan can be wrong about cancer. This type of testing may miss the presence of lung cancer or produce false positives that can lead to unnecessary and expensive additional testing.
If you had a CT scan that failed to find the presence of lung cancer, or if a CT scan wrongfully diagnosed an abnormality as cancer, you may be able to sue for your damages. If a health care provider’s negligence caused you to suffer physical, emotional, or financial harm, you might have grounds for a civil lawsuit .
