Is the abdominal pelvic CT scan with dye a risky thing to do?

In general, NO: A ct scan involves radiation, which is of minimal risk although pregnant women should probably delay nonemergent ct. "dye" or contrast as we call it, is also very low risk, however certain people have "contrast allergies" which can range from hives/itching all the way to catastrophic swelling and blood pressure loss which can lead to death. If you have severe allergies, tell your doctor before. ...Read more

The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

If dr orders a CT scan of abd/pelvic w/contrast an without, i can see it being done with contrast but what's the purpose of having it also without?

If dr orders a CT scan of abd/pelvic w/contrast an without, i can see it being done with contrast but what's the purpose of having it also without?

Several reasons: Most of the time, IV contrast is all you need for ct a/p. In some cases, it may be necessary to do both (and sometimes delayed images, too) to fully characterize something (e.g., some adrenal nodules, certain kidney or liver problems). There is added radiation each time you scan, so it is worth asking whether it is necessary for your problem. That said, it is common to do multiple phases. ...Read more

Is a CT scan without ivp dye as accurate as a CT scan with ivp dye of the abdomen? I have anaphylaxis to the dye.

See answer: Contrast (dye) adds additional characterization of soft tissues, vascular structures, and the urinary collecting system. Ct with contrast (if your dr. Feels the risks of a prophylactic steroid prep and a hospital based exam outweigh the risks) is an option or more safely, consider MRI or possibly an ultrasound. ...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?

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 more

Why would a GI specialist order an abdominal X-ray at the same time as abdominal ultrasound? What can X-ray show that u/s wouldn't? Is it redundant?

Why would a GI specialist order an abdominal X-ray at the same time as abdominal ultrasound? What can X-ray show that u/s wouldn't? Is it redundant?

Complimentary: Ultrasound is very good for evaluation of liver, gallbladder and to a lesser extent pancreas. Plain xray can evaluate bowel gas pattern and look for obstruction. CT (type of xray) can also evaluated for presence of masses and look at bowel pattern in more detail. CT not real good for evaluating gallstones. Thanks for trusting HealthTap! ...Read more

Can CT of sbdomen see aortic aneurysm? My doctor ordered a CT but have had 3 CT on brain. Is it safe to have another?

Can CT of sbdomen see aortic aneurysm? My doctor ordered a CT but have had 3 CT on brain. Is it safe to have another?

Yes ; Yes: The ct scans of your head have no real affect elsewhere. It's safe to have the abdominal one. The ct is the best method to see the overall size of an aneurysm, but it can underestimate blockages if not done with IV contrast to see the lumen (the opening inside). After you know you have an aneurysm, us may be used to follow it. ...Read more

What to do with conflicting CT scan results? I had a mammogram and a CT scan done. The CT scan showed a lump in my breast but the mammogram didn't show anything. What is done in situations like these? Should another test be done other than CT or mamogra

What to do with conflicting CT scan results? I had a mammogram and a CT scan done.  The CT scan showed a lump in my breast but the mammogram didn't show anything.  What is done in situations like these? Should another test be done other than CT or mamogra

Dedicated : Dedicated ct imaging of the breast is essentially only performed in a few research facilities, so i will assume that something was found in your breast incidentally during a ct of your chest. First, make sure that the radiologist performing the mammogram had the ct scan for comparison. If you feel the lump that was seen on ct, then you should probably have an ultrasound performed in the area for further evaluation. If you do not feel the lump and the radiologist compared the mammogram with the ct and was not concerned, then the ct finding was probably incidental and no further evaluation would be indicated. However, if you are still concerned you could have a follow-up mammogram in six months to ease your concern. ...Read more
