In ruling in or out cerebral aneurysm is mra study enogh or MRI with and without contrast is also needed with mra for better accuracy?
Best tests: Cta and mra studies should readily demonstrate any significant aneurysm. If such a lesion is congenital and small, it may be missed, but ruptures tend to occur when larger than 0.9 mm, and the others would just be followed. If you possess uncontrolled high blood pressure, an acquired aneurysm, called charcot-bouchard, could result in hemorrhage, so watch your bp. ...Read more
Does an abdominal CT scan with and without contrast have the same amount of radiation as two CT scans?
Yes: The ct scan will consist of at least 3 parts. A very low dose scan to show the anatomy and allow for planning of the full ct scan. The next scan is the "real" scan without contrast. Then there will be at least 1 scan with contrast, usually when the veins are most opacified, at about 70 seconds after the start of the injection. However, some contrast scans have multiple phases for some anatomy. ...Read moreSee 1 more doctor answer
Doubt it: If any irregularities in the intestinal wall were found, it would be just that, irregularities. Their presence would suggest a problem but the overlap with other possible conditions would make the information inconclusive. A normal study would also not rule out the condition. ...Read more

X-ray of your belly: Ct, or computed tomography is a special was of taking x-rays that allows up to see the body in slices. We use contrast, a type of x-ray dye, to better see blood vessels (iv contrast) and the GI tract (oral contrast). The abdomen covers from the diaphragms through the kidneys, and the pelvis covers from the hip bones to your upper thighs. They are done for mahy reasons, not just cancer staging. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer

Is an open mra and mrv good enough to diagnose any abnormalities with the blood vessels even without contrast?
For the most part: Both mr angiography (mra) and mr venography (mrv) of the head are usually performed without contrast dye using a special technique that can "see" flowing blood without IV contrast. Open mri? Depends on the machine. Some newer MRI scanners have larger openings without being "open, " and these strike better balance between patient comfort and image quality. May still miss small vascular lesions. ...Read moreSee 1 more doctor answer
Only if large enough: MRI with contrast has a resolution limit of about 5 mm, depending on the field strength of the magnet & the spin sequence performed (resolution of time-of-flight MRI or TOF-MRI is even worse). The "gold standard" for an aneurysm is a fluoroscopic angiogram of the brain, which only interventional neurologists or radiologists perform 4 (1) known stroke or (2) genetics.

Need to talk with : Your ordering doctor. Depends on what is being evaluated, and the differential diagnosis. Ct is a good quick screen for bleed, masses, skull fractures, etc. And MRI gets you good soft tissue details, and lets you better evaluate the gray and white matter, also allows you to evaluate bleeds, helps you tell if old or new bleed, also helps you see tumors, strokes (ischemic areas, atrophy, etc.). ...Read moreSee 1 more doctor answer
Had ct of head with and without contrast for HA. Results show small cyst and recommend MRI. Should I be concerned?
Not without symptoms: If you are not having symptoms, I don't think you even need an MRI. It's just wasting time & money going after an incidental finding. Most brain cysts are benign. If they were expanding, you would have neurologic symptoms (headache, vision probs). What prompted the MRI in the 1st place? Discuss with your primary doc or use HealthTap Prime to get advice from someone who knows your medical history. ...Read more

Does a contrast CT scan to view my kidney include both IV and oral contrast? Is this an abdominal CT scan or just renal/urinary?
Depends: It depends on what the doctor has ordered and is looking for. No contrast will be used typically if the doctor is looking for kidney stones. If they are looking and the tissue of the kidneys directly, IV contrast will be used. Generally oral contrast is not used when looking for kidney pathology. Your scan will also show the neighboring abdominal organs. ...Read moreSee 1 more doctor answer
