CT coronary angiography for assessing chest pain

CT coronary angiography (CTCA) is a noninvasive diagnostic modality that comprehensively evaluates coronary arteries and atherosclerotic plaque within them. It has a very high sensitivity for detecting coronary artery disease. International guidelines increasingly support CTCA as a first-line diagnostic test for assessing stable chest pain in select patients. CTCA also plays an important role in cardiovascular risk stratification and guiding management of patients with chest pain, by determining whether preventive therapies or further investigations may be needed.
