Is barium a better contrastvthen gastrografin for CT Scans. Had CT done in two diffrrent hospitals and one use Redicat (barium) and the other gastrogr?
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. 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
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
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
Due to have CT scan worried about allergy to contrast injection as my Son had Urticaria for a week two days after CT Scan with Contrast with Iodine .Have allergy to Almonds some metals nickel among others things .Suggestions please?
Talk to your: doctor about your concerns and allergy history. If you have a history of multiple allergies, you may be a candidate for pretreatment to minimize the chances of a reaction. The facility should have a protocol for this which could include one or more medications, so don't try to treat yourself. ...Read more
I had a CT scan with contrast dye and a mrcp with contrast on the same day-- 4hours apart. Also, scheduled a CT guided biopsy 2 days later. Any issue?
Be followed: As long as you have normal renal (kidney) function and you are monitored closely and well hydrated, you should be fine. Best wishes. ...Read more
Anaphylactic shock in 1987 from ivp dye for ct. Now need CT w/ contrast. 1 dr says i can have it because dye is different. Other dr says no. Thoughts?
IV contrast allergy: There are two basic types of dye used: ionic high-osmolality contrast media (hocm) and non-ionic low-osmolality contrast media (locm). Locm has become the preferred form of IV dye in recent years, given its better safety record. If you had hocm before, you may be ok with locm. You need to figure out what you had before and then proceed with caution. ...Read moreSee 1 more doctor answer

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
Could a cat scan show inflammation of the brain without contrast dye? I had a CT for amoeba and headaches & no dye was given but doc says i'm ok.
Not the best test.: In severe acute inflammatory processes, ct can detect brain edema, but it's unlikely you would be in a state to be able to recall that much. Assuming you're ok now, it's doubtful you had amebic encephalits, since that is a very nasty disease! ...Read moreSee 1 more doctor answer
Yes, but...: Reactions to contrast are usually not caused by a true allergy to iodine (which is rare). Low-ionic strength contrast should be used if you have a history of reactions to contrast, and the radiologist will give you antihistamines and corticosteroids (prednisone) before the test to help prevent a reaction. With this regimen, scans are usually very safe. Talk with the radiologist about your concerns. ...Read more
Luq pain for months now and nothing's been found.Would an abscess show in xray, blood, or a ct scan without dye?Those are the tests I've had done.
Maybe: Although ct scans are an excellent radiographic study, they can easily miss small bladder masses. If one should have a very large bladder mass, it will likely be seen. However, a cystoscopy is still required because the mass seen on ct scan does not neccessarily mean cancer. A tissue diagnosis with a biopsy is still required to make the definitive diagnosis. ...Read moreSee 1 more doctor answer
Why have CT scans with contrast fallen out of favor?Can ultravist oral contrast aggrivate a chronic inflamed and bumpy throat.Going for abdoman dcan
Unlikely: It is very unlikely oral contrast would bother your throat. In my practice, I have not found that contrast is out of favor. Both oral and IV contrast is usually the best way to go. ...Read more
Is it possible to look for a swollen lymph node for biopsy without having another CT scan? I already had two abd/pelv CT scans in the past 3 months.
Why do you ask?: If you have no palpable lymph node for biopsy, and none's known, why get the biopsy? The one disease for which a node might be sought for the purpose is sarcoidosis, but if it's worth treating -- and commonly it isn't -- you'll have a mass or symptoms that will show what should be biopsied. Perhaps there's another way of answering your personal health questions, or even a misunderstanding. ...Read more
Iv contrast +/- oral: After taking the contrast, taking the images does not take long. The IV contrast has potential 2 problems. You may be allergic to it like any medicine and it may slow down the kidneys if they are not working near full capacity. Your doc can tell the risk based on blood tests of kidney function. ...Read moreSee 1 more doctor answer
Intestinal spasms frequently lately. Would a CT scan w/out contrast show problems? Afraid of contrast due to several drug allergies.
Maybe: Ct without contrast can show some problems, but it is much more sensitive with contrast. Oral contrast particularly helps with intestinal evaluation, but IV can also be of benefit. Definitely get evaluated by a doctor first to see if they think you would benefit from a scan at all. And perhaps consider discussing your allergy concerns with an allergist. ...Read moreSee 1 more doctor answer
not needed: Thank you for your question. Most of the time appendicitis can be diagnosed without needing to use any imaging. A ct scan is sometimes used if there is some questions about whether you actually have appendicitis. Contrast has its own risk when consumed (mainly kidney concerns). Doctors try not to give contrast unless absolutely necessary and needed to show specific areas of the body. ...Read more
