Abstract: In the past few years, fast computed tomography evolved as a new diagnostic tool for cardiac diseases including calcium screening and non-invasive coronary angiography. Electron beam computed tomography (EBCT) was for over a decade the only modality to visualize structures of the heart without significant movement artifacts, however, modern spiral CT is a promising alternative: multislice CT allows data to be acquired simultaneously from 4 slices with a fast rotational time. The scanner operates in a spiral mode with the option of retrospective ECG gating. Calcium screening is performed in a single breath-hold without the application of contrast medium. CT angiography requires the administration of contrast medium via an anticubital vein. Protocols for the administration of new high-density contrast media are under investigation. This review article gives the current status of technology, indication and interpretation of results. J Clin Basic Cardiol 2001; 4: 241–3.

Conventional testing in patients with suspected coronary artery disease includes bicycle stress test, stress echocardiography and stress scintigraphy as well as invasive cardiac catheterization. Significant cardiac stenosis ( ≥ 75 %) in general causes typical angina pectoris (aggravating with physical activity and responding well to sublingual nitroglyc-
