The number of radiological imaging has increased in recent years because of increasing technological developments. This increment increased to the radiological contrast agents (CAs). CT technology has improved tremendously in recent years, even CT angiography (CTA) has substantially replaced digital ...
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 hand. ...
Purpose: To compare contrast-enhanced CT angiography (CTA) and gadolinium-enhanced MR angiography (MRA) for the detection of subsegmental-sized pulmonary emboli in a pig model. Material and Methods: In 5 anesthetized pigs, 3-mm diameter embolic materials made of Konjac, a semisolid food...
Direct hemorrhage of a bleeding aneurysm into the lateral ventricle was detected by CT angiography. This image clearly visualized that extravasated contrast medium spurting from a rupturing anterior communicating artery aneurysm, penetrated the ventricle wall and passed through the lateral ventricle to ...
In determination of brain death, brain CT angiography (CTA) can be used as a new ancillary test to assist EEG which is the current gold standard. We report a patient with barbiturate coma therapy whose CTA showed weak filling of the internal carotid artery and its branches...

with ICH in the non-contrast brain CT scan (NCCT) at presentation, age above eighteen years, and available brain CTA obtained within 48 h from primary NCCT. The exclusion criteria were history of head trauma within the previous two weeks, evidence of ischemic stroke on the site of hemorrhage...
Objective:To expore the value of CT angiography and CT perfusion imaging in brain in etiological diagnosis of transient ischemic attack(TIA).Methods:64-SCTP and 64-SCTA were performed in 20 patients with TIA diagnosed by neuroscience physicians.In all the 20 patients,there were 11 patients with ...
Aim To determine whether cerebral computed tomography (CT) angiography with a 16-detector row system can be performed using a reduced dose of contrast material. Materials and methods Twenty-eight patients were assigned to one of four protocols: A = 50 ml of 350 mg&...
