The art of assessing aortic stenosis

This review describes the assessment of the aortic valve by echocardiography and also the roles that multidetector CT (MDCT) and cardiac magnetic resonance have to play as complimentary imaging modalities....

Esophageal stenosis: three-dimensional multidetector CT and virtual endoscopy

The improvement in spatial, temporal, and contrast resolutions with the newest multidetector computed tomographic (MDCT) scanners opens the opportunity to explore other applications of the virtual endoscopy technique besides the colon and stomach evaluation. As a non-invasive technique, virtual esophagoscopy represents an alternative to conventional endoscopy for the assessment of esophageal stenosis. The procedure and diagnostic performance are reviewed. Findings of this modality are illustrated.

Using ECG-gated multidetector CT to evaluate global left ventricular myocardial function in patients with coronary artery disease.

Retrospectively ECG-gated three-dimensional volume data from multidetector CT (MDCT) coronary angiography enable image reconstruction of the cardiac cycle in the diastolic and systolic phases. The objective of our study was to investigate the feasibility of determining left ventricular function from MDCT coronary angiography data sets in 22 patients with coronary artery disease and to study the correlation of MDCT results with those of functional data from biplane cineventriculography. Multiplanar reformations from three-dimensional MDCT data allowed good delineation of endocardial and epicardial left ventricular contours. In patients evaluated for coronary artery disease, MDCT coronary angiography with retrospective ECG gating provides functional data in an acceptable correlation (r = 0.8; p < 0.05) to biplane cineventriculography.
