What to Expect During Your CT Angiogram The exact procedure of your CT angiography will vary depending on your specific condition. Generally, you can expect the procedure to begin with a clinician placing you on the exam table and administering the contrast material through an IV in your arm or...
An angiogram is a specific type ofCT scanwith contrast. In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest. What is a CT angiography used for? A computerized tomography (CT) coronary angiogram isan imaging test that looks ...
A good-quality CT pulmonary angiogram has a high accuracy rate for the evaluation of PE. Investigators have reported that subsegmental emboli can be missed; however, visualization of smaller arterial branches and, therefore, detection of small emboli have improved with the availability of multidetector...

Conclusions By using a reduced dose (50 ml) at higher iodine concentration (350 mg I/ml) with an SF, CT angiograms comparable with those acquired with a standard dose and concentration can be obtained. 展开 DOI: 10.1016/j.crad.2008.07.007 被引量: 10 ...
CT angiography of pulmonary embolism in patients with underlying respiratory disease: impact of multislice CT on image quality and negative predictive value Our objective was to evaluate the impact of multislice CT (MSCT) on image quality and diagnostic value of spiral CT angiograms. Over an 8-...
Angiogram risks As with any procedure that involves X-rays, an angiogram exposes you to radiation. Complications from an angiogram are rare. However, potential risks include: Injury to the catheterized artery An allergic reaction to the medication or contrast agent ...
