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”.

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

See a surgeon: A general surgeon does not necessarily mean you need surgery, but their training makes them experts in abd pains.

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
