The report should include Technical details : About the MRI Scanner and sequences used. The mentioning of sequences is important for follow up of case. Brief clinical details : Presenting complaints, DRE examination findings*, PSA values*, Biopsy details* & any previous MRI study, if available. Findings : The size of the Prostate.
Mp-MRI assesses water molecule motion (called water diffusion) and blood flow (called perfusion imaging) within the prostate. This helps your doctor tell the difference between diseased and normal prostate tissue.
Prostate MRI does not use radiation. It provides images that are clearer and more detailed than other imaging methods. Tell your doctor about any health problems, recent surgeries, or allergies. The magnetic field is not harmful. However, it may cause some medical devices to malfunction. Most orthopedic implants pose no risk.
False-positive diagnoses of areas of potential cancers at MP-MRI create clinical uncertainty and often lead to multiple unnecessary biopsies or in certain cases surgical management of low-grade, low-volume disease.
A recent review showed that previous studies of MRI to detect clinically significant prostate cancer yielded NPVs of 63% to 96%, as determined by biopsy or prostatectomy specimen.
And it becomes even more difficult when those tools contradict each other. Finding high levels of PSA, a protein made in the prostate gland, in a man's bloodstream can indicate prostate cancer. However, PSA testing has a 15 percent false-positive rate, which means the test may detect cancer that isn't present.
The findings of this Cochrane review suggest that the MRI pathway is better than systematic biopsies in making a correct diagnosis of clinically significant prostate cancer. However, the MRI pathway still misses some men with clinically significant prostate cancer.
Chronic prostatitis might mimic prostate cancer at Mp-MRI with low T2 signal intensity at T2WI, mild diffusion restriction on the ADC map, decreased citrate peaks and elevated choline peaks, and significant contrast wash-in and wash-out at DCE (Figure 5).
The authors concluded that 9.9% of all the cancers, most of which were clinically significant, were not diagnosed, even though 20-core biopsies were taken. In this study, the false negative rate of 12-core prostate biopsy technique was found to be more than 30%.
Although tests aren't 100% accurate all the time, receiving a wrong answer from a cancer biopsy – called a false positive or a false negative – can be especially distressing. While data are limited, an incorrect biopsy result generally is thought to occur in 1 to 2% of surgical pathology cases.
The prostate specific antigen (PSA) density was significantly lower in the false-positive group than the those diagnosed with cancer (median, 0.08 vs. 0.14; p=0.02). Men who have had a previous biopsy were more likely to have a false-positive MRI reading (90.5% vs. 63.6%, p=0.04).
The most accurate test for detecting prostate cancer is a prostate biopsy. This biopsy involves taking a tissue sample from the prostate and examining it under a microscope, which can help your doctor determine whether there is an uncontrolled growth of cells in the prostate gland.
The test doesn't always provide an accurate result. An elevated PSA level doesn't necessarily mean you have cancer. And it's possible to have prostate cancer and also have a normal PSA level.
Two important histopathological prostatic lesions are benign prostatic hyperplasia and Prostatic carcinoma. These lesions cause enlargement of prostate gland, constricting the urethra and thus causing various urinary symptoms.
In conclusion, multiparametric MRI can be the best imaging modality for the assessment and diagnosis of chronic prostatitis and its differentiation from prostate cancer.
Benign prostatic hyperplasia, a noncancerous enlargement of the prostate gland, is the most common benign tumor found in men. As is true for prostate cancer, BPH occurs more often in the West than in Eastern countries, such as Japan and China, and it may be more common among black people.
MRI of the prostate is primarily used to evaluate prostate cancer. Your doctor will use this exam to: detect suspected prostate cancer. measure the size of cancer (local staging) see if cancer has spread ( metastasized) monitor any changes. assess the effectiveness of treatment. look for any treatment complications. see if cancer has returned.
The report is written for your doctor. So, it contains medical terms you may find hard to understand. The report commonly includes six sections:
These are called incidental findings because they were not the reason the exam was ordered.
In this section, the radiologist gives a diagnosis based on the findings, your medical history and the reason for the exam. This is the most important part of the report.
PI-RADS scores range from 1 (most likely not cancer) to 5 (very suspicious). The five scores include:
What is MRI of the Prostate? Magnetic resonance imaging (MRI) is a noninvasive test used to diagnose medical conditions. MRI uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of internal body structures. MRI does not use radiation (x-rays).
Your doctor uses MRI to evaluate prostate cancer and see if it is limited to the prostate. Mp-MRI provides information on how water molecules and blood flow through the prostate. This helps determine whether cancer is present and, if so, whether it is aggressive and if it has spread.
To prepare for an MRI with the endorectal coil, eat light meals on the day prior to and on the day of your exam. This will help make it easier to insert the coil. Your doctor may ask you to use an enema before your exam to help clear your bowel. Enema kits or saline laxatives are available over the counter.
Magnetic resonance imaging (MRI) uses a magnetic field, radiofrequency pulses, and a computer to produce detailed pictures of the body. Doctors use Prostate MRI to evaluate the extent of prostate cancer and determine whether it has spread. They may also use it to help diagnose infection, conditions you were born with, or an enlarged prostate. Some exams may use an endorectal coil, a thin wire covered with a latex balloon. The doctor inserts the coil a short distance into the rectum. Prostate MRI does not use radiation. It provides images that are clearer and more detailed than other imaging methods.
Your doctor will typically use an endorectal coil with low-field (1.5 Tesla) MRI magnets if you have a metal orthopedic implant. Metal implants may interfere with imaging when using a high-field magnet MRI. The doctor will typically not use an endorectal coil with high-field (3 Tesla) MRI units.
Placing the coil into the rectum so close to the prostate helps generate more detailed images. It also enables your radiologist to perform magnetic resonance (MR) spectroscopy. MR spectroscopy can provide additional information on the chemical makeup of cells in the prostate.
This detail makes MRI a valuable tool in early diagnosis and evaluation of the extent of tumors, such as prostate cancer. MRI has proven valuable in diagnosing a broad range of conditions, including cancer. It is also useful in diagnosing benign conditions such as an enlarged prostate and infection.

MRI prostate is useful at detecting and locally staging prostate cancer but there are false positives. Features of cancer are T2 hypointensity with restricted diffusion and early, rapid washout enhancement as in this case.
MRI doesn’t use radiation, and it isn’t invasive or painful. In fact, it’s one of the safest medical procedures available. So there’s not a lot of risk that comes with getting an MRI, but there are a lot of benefits. This makes the prostate MRI a powerful tool.
There’s not much you need to do to prepare for your MRI. If you’re getting sedation medication, you won’t be able to have anything to eat or drink for about 8 hours before your MRI. If your provider needs to use an endorectal coil during your MRI, they might ask you to take an enema a few hours before the procedure.
Prostate MRIs are becoming more common. They’re powerful tools that help your healthcare team get an accurate picture of your prostate. They also help guide prostate biopsies so that you can get accurate results and start treatment as fast as possible. And fortunately prostate MRIs are short and relatively painless.
Unlike x-ray and computed tomography exams, MRI does not use radiation. Instead, radio waves re-align hydrogen atoms that naturally exist within the body. This does not cause any chemical changes in the tissues.
Your doctor uses MRI to evaluate prostate cancer and see if it is limited to the prostate. MRI provides information on how water molecules and blood flow through the prostate. This helps determine whether cancer is present and, if so, whether it is aggressive and if it has spread.
Before the scan the doctor or nurse will ask questions about your health. As the scan uses magnets, they will ask whether you have any implants that could be attracted to the magnet. For example, if you have a pacemaker for your heart you may not be able to have an MRI scan. Youll also need to take off any jewellery or metal items.
MRI examinations require that the patient hold still for long periods of time. We provide MRI-compatible CinemaVision goggles so that our young patients can watch movies during their MRI procedure. Patients can either choose a movie from our movie list or bring one from home.
For R1, DWI geometric distortion was significantly less pronounced in the HBB+/ME+/DR as compared to the HBB/ME/DR and HBB+/ME/DR cohorts. For R2, DWI geometric distortion was significantly more pronounced in the HBB+/ME/DR as compared to the HBB/ME+/DR and HBB+/ME+/DR cohorts. DWI IQ was rated similarly by both readers.
For the duration of the MRI, you will be lying in an enclosed tube-shaped machine. While the length of time youll spend in there will vary, it could be as long as an hour. If youve ever dealt with claustrophobia, you may find this causes you a great deal of anxiety.
The traditional MRI unit is a large cylinder-shaped tube surrounded by a circular magnet. You will lie on a table that slides into the center of the magnet.
1. Calculate Prostate gland volume: It is measured using the formula - maximum anterior posterior diameter x maximum transverse diameter × maximum longitudinal diameter x 0.52. We personally prefer T2W and T2 Fat suppressed images for the measurements.
After interpreting images, it is time to formulate the report. The report should include
