Case history 64 year-old female presents with history of neck and chest pain. Diagnosis Thickened quadricuspid pulmonary valve. Aneurysmal dilatation and asymmetry of pulmonary arteries. Stenosis of mid LAD with a component of myocardial bridging. Description Had “Definition” not been available, patient would have been imaged using routine helical sequence at presumably larger … Read more

Cardiac MDCT proves to be reliable source for detection of morphology of aortic valve. 4D images of phases between 0-90 % enable functional assessment of aortic valve and identification of degree of severity of valvular disorders. Read more

Electro-cardiogram (ECG)-gated dual energy computed tomography (DECT) of the heart may enable spectral analysis of the myocardium for areas of decreased blood supply in addition to morphological assessment for coronary artery stenosis. We used DECT for evaluating a 49-year-old woman with known coronary artery disease and new onset chest pain. She … Read more

To prospectively evaluate the effect of heart rate, heart rate variability, and calcification on dual-source computed tomography (CT) image quality and to prospectively assess diagnostic accuracy of dual-source CT for coronary artery stenosis, by using invasive coronary angiography as the reference standard. Read more

In this article we describe current multislice CT techniques for coronary artery imaging and illustrate coronary artery anomalies and clinically important coronary artery anatomy from the point of view of congenital heart disease. Read more

Marketing claims accompanying the launch of a new high-end imaging system are always to be taken with a grain of salt. In the case of coronary CT angiography with 2nd generation dual-source CT, however, the emerging literature and our own experiences using this system largely support the pre-launch projections. These … Read more
