Value of transluminal attenuation gradient of stress CCTA for diagnosis of haemodynamically significant coronary artery stenosis using wide-area detector CT inpatients with coronary artery disease: comparison with stress perfusion CMR

This study aimed to evaluate the value oftransluminal attenuation gradient (TAG) of stress coronarycomputed tomography angiography (CCTA), using a wideareadetector CT in patients with coronary artery disease,compared to stress perfusion cardiac magnetic resonance(CMR) imaging
