Objective: To evaluate the relation between epicardial adipose tissue (EAT)\nthickness and also pericoronary fat assessed by Multidetector Computed\nTomography (MDCT) with both calcium score and significance of coronary\nartery disease. Background: Epicardial adipose tissue (the visceral fat of the\nheart present under the visceral layer of the pericardium) has the same origin\nof abdominal visceral fat, which is known to be strongly related to the development\nof coronary artery atherosclerosis. Multidetector CT (MDCT) provides\nan accurate and reproducible quantification of EAT due to its high spatial\nand temporal resolution. Patients and Methods: The current study included\n70 patients with low-intermediate probability of coronary artery disease.\nAll patients were subjected to 256 Multidetectors CT to assess EAT\nthickness, the mean thickness of the pericoronary fat surrounding the three\ncoronary arteries and coronary calcium score. Also coronary CT angiography\nwas done and patients were then divided into 3 groups according to significance\nof coronary atherosclerosis: Group 1: No atherosclerosis (20 patients),\nGroup 2: Non obstructive atherosclerosis (luminal narrowing less than 50%\nin diameter) (25 patients), Group3: Obstructive atherosclerosis (luminal narrowing...................
