A Pelvis MRI is a specialized scan that uses strong magnetic fields and radio waves to create detailed images of the organs nestled within the pelvic bone.
Doctors request this scan when investigating unexplained pelvic pain, diagnosing reproductive issues, or staging certain types of cancers.
Unlike CT scans, a Pelvis MRI excels at distinguishing between different types of soft tissues, making it the preferred test for evaluating the uterus, ovaries, and prostate.
Why would my doctor ask for a Pelvis MRI?
Your doctor may recommend a Pelvis MRI to look closely at your lower body, especially if you have:
- Unexplained pain in your lower abdomen or pelvic region.
- Abnormal bleeding or difficulties with urination or bowel movements.
- For women: Suspected fibroids, endometriosis, or abnormal ultrasound results.
- For men: Unexplained lumps in the scrotum or testicles, or an elevated PSA (prostate-specific antigen) blood test.
What can a Pelvis MRI detect?
A Pelvis MRI helps doctors visualize:
- The bladder, rectum, and lymph nodes.
- In women: The uterus, ovaries, fallopian tubes, and cervix.
- In men: The prostate gland, seminal vesicles, and testicles.
It is particularly useful for identifying:
- Tumors or cancers of the reproductive organs, bladder, or urinary tract.
- Endometriosis, ovarian cysts, or uterine fibroids.
- Structural abnormalities or birth defects.
- Injury or trauma to the pelvic region.
Do I need any special preparation for a Pelvis MRI?
Yes, pelvic MRI preparation depends on what organs are being evaluated:
- Fasting: You may be asked to fast (no food or drink) for 4 to 6 hours before the scan to reduce bowel movement, which can blur the images.
- Bowel Prep: In some cases, you may need to use a mild laxative or enema to clear your bowels before the exam.
- You must remove all jewelry, piercings, and metal items, and change into a hospital gown.
Will I be injected with dye for this scan?
Often, yes. A contrast agent called gadolinium may be injected into a vein in your arm. This dye highlights blood vessels and makes it easier for the radiologist to see inflammation or tumors. If you have a history of kidney disease or allergies, inform your doctor before the scan.
What does a Pelvis MRI feel like?
The scan is painless. You will lie on a padded table that moves into a large, tube-shaped MRI machine.
A special receiving device (a coil) may be placed lightly over your lower abdomen to pick up the signals. The machine makes loud humming and knocking noises, so you will be provided with earplugs or headphones. The radiographer will communicate with you via an intercom, and you will have a call button if you need assistance.
Is it safe for pregnant women or children?
MRI does not use ionising radiation. Noncontrast pelvic MRI may be performed during pregnancy when clinically justified; it is not automatically prohibited in the first trimester. Gadolinium is not routinely given during pregnancy.
How long does the Pelvis MRI take?
The scan usually takes between 30 and 60 minutes, depending on the specific views requested by your doctor.
When will I get my results?
After the scan, a Radiologist will carefully review the images and prepare a report. Results are usually ready within a few days, and your doctor will discuss the findings with you.
Do I need to have a full bladder for a Pelvis MRI?
It depends completely on what your doctor is evaluating. For some exams, like looking at the uterus or checking for endometriosis, a partially full bladder is requested because it helps lift the pelvic organs into better view. However, for other scans, you may be instructed to empty your bladder right before the scan so that you are comfortable and can remain still. Always follow the specific instructions given to you by your imaging center.
