Concerning atherosclerosis imaging and coronary calcium concentrates predominantly on electron beam computed tomography (EBCT).1 Non-invasive coronary artery imaging can take the form of coronary artery calcium assessment or coronary angiography. Imaging can be performed with EBCT, or since 2001, with the latest generation of helical (‘spiral’) CT scanners (known as ‘multislice’ CT scanners in view of simultaneous acquisition of four image ‘slices’). There are major differences between EBCT and multi-slice helical CT. Whereas with helical CT the patient is continually advanced through a rapid mechanically rotating gantry (X-ray source and detector array), EBCT relies on X-rays produced with an electronically steered electron beam.
