Ct Scan Ivp
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
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
Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously. Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more
Is a re CT scan appropriate for 3.4mm stone in right proximal uteter of horshoe kidney? Mild achy pain to right side for 8 months. Ivp was normal.
CT is: Appropriate for following up calculi, but you should probably consult with a urologist about the most appropriate next steps for you. ...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 more

Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density. Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor. ...Read more
Pretty easy: As in the picture, you will lie on a table which will then slide you into and out of the scanner during the scan. The scanner loos kind of like a big donut. Not nearly as long and narrow as an MRI scanner. Depending on the scan you may be asked to drink barium oral contrast before the scan to opacify the bowel lumen. Also, you may or may not have IV contrast injected during the scan. ...Read more

PET/CT scan: You need to fast for 4 hours first, then you will recieve an injection of a small amount of radioactive glucose (i.e. Sugar). Next you will sit in a recliner chair for about 70 minutes to allow the glucose to distribute throughout you. Then you will lie on your back on the pet/ct scanner (a tunnel shaped machine) for 20 minutes. There are no side effects from the test or restrictions afterwards. ...Read more
Yes,: Barium is safe with a CT scan. Dilute barium is often used as oral contrast for a CT. Non dilute barium (for example from a barium enema) will cause an artifact on CT which could obscure much of the anatomy and render the scan useless, so although it is not harmful to you, it could ruin the scan. ...Read more
Your doctor: Your doctor should help you understand your report. Unless you went to medical school or have other medical training, the vocabulary used in most reports will be very confusing, and even using a medical dictionary may not fully explain what the radiologist is trying to communicate. ...Read more
Several uses: In most cases PET CT scan is used for detecting metatases in the body. It can also be used for brain with mets, primary tumors, and epilepsy. Injection of glucose metabolite F18 FDG goes to malignant lesions that are highly metabolic, . Usually more sensitive for detecting smaller lesions. Used in staging malignancies and following patient's response to chemotherapy and radiation ...Read more
Perspective: It depends on why you are getting it. Is the risk greater than the benefit? If so, then probably not a good idea to get it. If the potential benefit is greater than the risk of not getting it, then I'd say absolutely, get it done. However, just know, the radiation exposure to a CT is about the same as 200 chest X-rays. ...Read more
