Ct Angiogram Vs Ct With Contrast
Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...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

Not same: Mri contast gadolinium does not contain iodine while ct contrast contains iodine. An allergic reaction to ct contrast does not mean that you will have a reaction to gadolinium during your MRI scan. True allergies to the MRI contrast are exrtremely rare; however, you may still experience some symptoms like feeling lightheaded or nauseated due to the injection. Good luck with the exam! ...Read more
No: Iv contrast is often not used when the ct is for the purpose of looking for renal stones and in people with a history of contrast allergy or renal disease.

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
Not really!: The CT will show spasm or edema ( swelling of the bowel wall) but you need something such as endoscopic studies to rule out any inflammatory disease which is a serious health issue, unlike that of irritable bowel which is also painful but not progress in most cases. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer

CT only: It is obvious that you wish to avoid ionizing radiation. However MRI is difficiult in imaging lungs of low density tissue, air-tissue interfaces causing artifacts, and respiratory, cardiac, and vascular motions.These are technicalities without any control. Ct is by far the choice for imaging bronchiectasis. ...Read moreSee 3 more doctor answers
UltraSOUND: I think you mean cardiac ultrasound (also known as echocardiography). They look at different things. Echo sees over all function, wall thickness, chamber dimensions, valves, and can measure blood flow and pressure. Ct is for detecting calcium and looking at the coronary arteries. ...Read more
Whats better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.
CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and cea can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more
