This way the body is shown in slices, in any plane, usually axially, but ...Read more
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
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
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

Can unruptured anuerysm present with neck pain with and without headaches. Would an anuerysm large enough to do damage be seen on plain CT scan?
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
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

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
Have 5-6 mm calcified lump in the posterior neck, doctor recommend imaging. Should do MRI with and without contrast or CT w/ contrast? Benefits/risks?
Neither!: If you know the lump is calcified, you're best off not doing any imaging. If you want to know what it is, go to a surgeon or pathologist who can manage a simple biopsy, probably in his office, to figure out what it is. A FNA (fine needle aspiration) may work out for you. If you REALLY need to know if it is solid or a cyst, then ultrasound is better. CT involves radiation. MRIs are $$. Avoid them. ...Read moreSee 2 more doctor answers
