Abstract:
The study aimed to determine the role of spiral CT Angiography in suspected cases of acute Pulmonary Embolism at duration (Agusust –November 2011)
The study was conducted at EL-Nilien center , Royal care center and Faisal center where there were enough cases to study and the availability of required machine and materials to perform proper examination .
Fifty patients of suspected pulmonary embolism (PE) of different ages and genders underwent spiral CT angiography from the level of arch of aorta to the dome of diaphragm . Scanning was done using Semince(4 multi slice) and Toshiba (64 multi slice ) machines with collimation of 1-2mm and an interval of 2mm at 60-160 mA and 120-135kV 100ml of contrast was injected at a flow rate of 3-4 ml sec with a scan delay of 12-16 second . Spiral CTA was found to be an effective method for the diagnosis of pulmonary embolism . Out of 50 patient 38 (76%) were positively identified with pulmonary embolism , more over females were most likely presented with PE . Additionally during the study , it was noted that the Rt pulmonary artery was affected more than the Lt pulmonary artery .
The research confirmed that, the spiral CT scanner more acurat modality in detection of pulmonary embolism , it is non –invasive procedure , low cost , and has a high specificity , for that preferred it used as the first line of investigations in diagnosing of Pulmonary embolism .
