Confused.Ar my request my gastro ordeted abdominal mra.Ct was normal.Order changed by radoologist to do abdominal MRI instead of mra.Scared as to why.

Abdominal MRA: Either the radiologist called your GI doctor and then changed the order, or they are acting inappropriately. Mra stands for “magnetic resonance angiography”. Mra of the abdomen is a quick and accurate noninvasive test to look at the arteries in your abdomen. If there is a risk that your symptoms are due to arterial issues this is the test that should be done. ...Read more

Abdomen pain and suspicion, should I get a CT scan or mri?

Abdomen pain and suspicion, should I get a CT scan or mri?

Maybe: First exam should be a simple abdomen xray. If doctor thinks the gallbladder could be diseased, then an ultrasound is best. Most other ailments best served with a ct scan. Mri can help if a patient can't have ct contrast because of prior reaction or poor functioning kidneys. Mri scans take longer, cost more, and not readily available as ct scans. ...Read more

Can CT scan and MRI of pelvis and abdomen also gather images of the interior colon?

Can CT scan and MRI of pelvis and abdomen also gather images of the interior colon?

CT Colongraphy: A special ct with bowel cleansing and gentle inflation of the colon can provide an excellent view of the inside of the colon. This specific protocol is called ct colonography, and not every imaging center or hospital can perform it well. Ask about special reviewing software, and how many ct colonographies performed per week. ...Read more

Female 32 lower left abdomen pain 6+ months MRI/CT scan normal pain worsens with coughing sneezing and laughing have IUD any suggestions?

See a surgeon: A general surgeon does not necessarily mean you need surgery, but their training makes them experts in abd pains. A good History and physical may reveal possible causes, for example, if you ever had surgery, you may have adhesions in that area and when coughing, the "valsalva maneuver" is causing referred pain in the area, etc. Best wishes. ...Read more

Mammogram necessary? 7 PET/CT scans, 1 CT w/ dye, 1 chest CT w/o dye and abdominal MRI in last 26 months. All clear. Do I need a mammogram this year? Been 2 1/2 yrs Age 63 small breast. No concerns

Mammogram necessary?  7 PET/CT  scans, 1 CT w/ dye, 1 chest CT w/o dye and abdominal MRI in last 26 months. All clear.  Do I need a mammogram this year? Been 2 1/2 yrs Age 63 small breast. No concerns

Yes: Screening mammography works best when you get the test once per year. Unfortunately none of the other tests you've had are a suitable substitute. The radiation from your mammogram will be a tiny fraction of the radiation you received from the other tests. All of those tests you've had add up 100's of mammograms, so one more won't make a difference in terms of your overall exposure. ...Read more

Will an abdominal MRI show stomach cancer?

Will an abdominal MRI show stomach cancer?

Potentially: An mri of the abdomen shows the structures in the abdomen, and it would show a gastric cancer that is large enough to be detectable. In its very early stages, gastric cancer may be subtle enough to not be detected on mri. Don't hesitate to discuss directly with your gi Doctor. ...Read more

Will an abdominal MRI show the colon if colon cancer is present? What about the rectum?

Not best test.: While abdominal MRI can show signal changes as a result of colon cancer, if the tumor / polyp is small, or in a fold, then there's a high probability of missing it. CT colonography is a better test, but has limitations. The BEST test is a colonoscopy (by an experienced Gastroenterologist). In fact, colonoscopy is used to SCREEN for colon cancer in high-risk populations. TTYD or use HealthTap Prime ...Read more

I had a MedTronic Loop recorder implant placed 6 months ago by my EP. My GP wants to do an abdominal MRI. Is this a contradiction with my implant?

If the loop: recorder you have is the Medtronic "Reveal LINQ" it is OK for MRI. Specific conditions MUST be met and are listed on page four of this manual. http://manuals.medtronic.com/wcm/groups/mdtcom_sg/@emanuals/@era/@crdm/documents/documents/contrib_188127.pdf. Have the radiology facility confirm these requirements and then you will be OK if they are met. ...Read more

Does an abdominal MRI check for tumors or blockages in the intestines?

Does an abdominal MRI check for tumors or blockages in the intestines?

Not very well: Mri does not image the intestines well at all. Mri only images organs that are not moving. The intestine is continuously moving (called peristalsis) and becomes blurred on most MRI scans. Abdominal mr usually is used for imaging the solid intra abdominal organs. Mr does not have the temporal or spatial resolution to see intestinal blockages or tumors. ...Read more

I had an abdominal MRI with contrast, is this the same as an MRCP or do I need an MRCP for pancreas/ Gall bladder evaluation?

MRCP: These tests are not the same. The MRCP uses a special protocol to see the bile duct and the pancreas in better detail. It would not be seen this way on a regular MRI of the abdomen. If your physicians feel that you need a test specific for the bile ducts, they will order the MRCP. Good luck. ...Read more

What does moderately fluid distended gallbladder mean? Noted on abdominal MRI, common bile duct diameter at 6mm. & I have alot of abdominal symptoms.

What does moderately fluid distended gallbladder mean? Noted on abdominal MRI,  common bile duct diameter at 6mm. & I have alot of abdominal symptoms.

As an isolated: finding it is of uncertain significance, it may mean nothing. It has to be interpreted in the context of your entire clinical picture, i.e. does your doctor suspect gallbladder dysfunction or biliary problem. Likewise, a 6mm common bile duct is borderline abnormal. If you have no signs, symptoms, or lab values suggesting biliary obstruction, it may be normal for you. ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
