Objectives: The study aimed to determine the role of spiral CT Angiography in suspected cases of acute Pulmonary Embolism at duration (August – November 2011) 5th Arab Radiology Congress (ARC5) April & 6th PAIRS Meeting April Hammamet - Tunisia

Materials and Methods: The study was conducted at EL-Nilin center, Royal care hospital 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 mA and kV 100ml of contrast was injected at a flow rate of 3-4 ml sec with a scan delay of second.

Figure(1) shows CT Equipment

Results: Out of 50 patient 38 (76%) were positively identified with pulmonary embolism,male 32% and females 68% fig (2),Shortness of breath is the most clinical indication with (54%) incidence, followed by Cyanosis (14%), Chest pain (12%), Couph (12%),and Haemoptysis Additionally during the study, it was noted that the right pulmonary artery was affected more than the Lt pulmonary artery.figur(1,2, and 3) 5th Arab Radiology Congress (ARC5) April & 6th PAIRS Meeting April Hammamet - Tunisia

Conclusion: The study confirmed that, the spiral CT scanner more accurate 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. 5th Arab Radiology Congress (ARC5) April & 6th PAIRS Meeting April Hammamet - Tunisia
