Abstract: Background: Nowadaysamong non communicable diseases Coronary artery disease heads in both in mortality and morbidity.Its early detection and hence cure needs multimodal diagnostic tools CT scan being among the latest modality.The diagnostic value of conventional coronary angiography has been challenged by the emergence & fast growing use of a less invasive imaging technique, multislice computerised tomography (MSCT) angiography to avoid radiation hazard. From time to time ,the manufacturers have implemented strategies to reduce the radiation exposure and these include ECG-gated dose modulation, automated exposure control,lowering the tube voltage,& increasing the pitch value with the use of dual source CT scanners.The non-invasiveness of this technique........
