Objectives - The recent newer advances in computed tomography have dramatically changed our approach to imaging cardiac disease. This study sought to compare the diagnostic value of 16-multi-detector spiral computed tomography (MSCT) for detecting coronary artery stenosis. Methods - A total of 88 consecutive patients (52 men, mean age 68 +/- 8 years) with atypical chest pain, stable angina or suspicion of ischaemia at stress test were studied by MSCT and invasive coronary angiography (ICA). The MSCT images and multiplanar reconstructions were analysed regarding the presence of >= 50% coronary artery lesion. Results - All 88 scans obtained at a mean heart rate of 68 8 beats/min were interpretable. Sixteen coronary segments were evaluated in each patient. Of the 1320 segments examined, 148 (11 %) showed poor image quality. A total of 150 significant lesions were detected using ICA, and 80 of 150 (53%) were detected by MSCT Sensitivity, specificity, positive and negative predictive values were as follows: 53%, 97%, 68%, and 94%. Fifty-four patients had >= 50% coronary stenosis. The diagnosis was confirmed by MSCT in 42 patients and correctly ruled out in 30. By patient-based analysis, positive and negative predictive values were 91 % and 71 %. Conclusion - Although its specificity is high, the sensitivity of 16-slice MSCT for detecting 2: 50% coronary stenosis in non-selected patients submitted to ICA is rather low suggesting that for daily practice the diagnostic value of this technique should be improved.

Cardiac imaging has always been a challenge because of the continuous movement of the heart. Cardiac computed tomography (CT) has undergone an accelerated progression over the past decade, due to the combination of the high-speed rotation of the X-ray tube, the ECG-gating technique and the infra-millimeter spatial resolution. Multidetector CT allows visualisation of the coronary artery lumen and the detection of coronary stenosis after intravenous injection of contrast medium. Studies have demonstrated a high negative predictive value of CT coronary angiography (CTCA). CTCA may be reasonably used for the assessment of symptomatic patients, especially in the setting of equivocal treadmill or functional testing. Also, CTCA allows assessment of coronary bypass graft patency and recognition of aberrant coronary arteries. Limitations in the use of this technique exist: atrial fibrillation and other cardiac arrhythmias remain a contraindication; severe calcifications are the most frequent reason for impaired assessment of coronary arteries. High radiation doses prohibit the use of this test as a screening tool for asymptomatic patients. [less ▲]
