This way the body is shown in slices, in any plane, usually axially, but ...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 moreSee 1 more doctor answer

Depends on the need: A ct can be used in pregnancy when absolutely necessary and when other options are not appropriate. A ct scan has a higher level of radiation exposure than other imaging methods so it is not the first choice. Mri, sonograms and even x-ray would be chosen first. In some medical conditions a ct is the best option in spite of the exposure. Make sure you discuss the reason for the ct scan with doc. ...Read moreSee 1 more doctor answer
Not aware of testing: The risk of an adverse reaction to non ionic IV contrast dye is very low, less than 1 in 100 injections. Most of the reactions are mild and easily treated. Severe reactions occur in 1-2 per 10, 000 injections of IV non ionic contrast. If a person was severely allergic to many different things, perhaps a consultation with an allergist could be obtained. ...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
I'm fasting for Ramadan and I need to have a CT scan with IV contrast. Is it dangerous for me to have the CT scan during the fast?
Hydration: No problem as long as well hydrated. IV contrast is excreted through kidneys and can cause renal dysfunction if dehydrated. Usually requested to be NPO few hours before testing. ...Read more
If I have a CT scan w/contrast done on Thursday and bone scan done the following Monday will the contrast effect bone scan results? If so how?
Yes: In fact, ct scanning without contrast is becoming the gold standard evaluation for kidney stones. Contrast material frequently obscures stones and makes their identification difficult. Stones as small as 1 mm can be detected with unenhanced ct technique. Radiolucent stones which cannot be seen well with plain x-ray technique do show up well with unenhanced ct scan. ...Read more
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation. The most common types of radiation are called alpha, ...Read more
