DIAGNOSIS OF CORONARY ARTERY DISEASES BY CT SCAN

Abstract

The aim of the study is to evaluate the accuracy t reveal advantage and disadvantages of CT chest angiography in diagnosis and treatment of coronary arteries diseases (CAD) in patients with suspected CAD. Retrospectively this study carried out in 80 patients in UAE from 1/12014 to 1/6/2015. Their ages running between (26- ), 55 patients are male percentage (68.8%) And 25 patients are female percentage (31.2%). 80 patients with suspected CAD underwent low-dose prospective electrocardio-gram gated coronary CTA, with images reconstructed using 256 slice CT scan of vessel and patient based levels. The patient data were divided into five groups (calcium scores of (0), (1-10), (11-100), (101-400) and 4000). The differences in diagnostic performance between the five groups were tested. Most patients are within chest pain and the study found that the main affected age group (46 -55). The study conclude that CT is accurate in diagnosing of coronary artery diseases low-dose prospective coronary CTA with 256 slices can acquire satisfactory image quality and show high diagnosis accuracy in patients with suspected CAD however, blooming continues to pose a challenge in severely calcified segments.
