Heart evaluation by cine CT: use of two new oblique views.

Abstract

Two new oblique views on cine computed tomography for examination of the left ventricle of the heart are described. A short-axis view sections the left ventricle transversely, demonstrating all the ventricular walls; a long-axis view sections the left ventricle longitudinally, demonstrating the mitral valve, proximal aortic root, aortic outflow tract, and ventricular apex. These views are produced by a combination of table slew and patient positioning. Reproducible short-axis views were obtained in 16 healthy volunteers and 11 patients. Long-axis views were obtained in 11 patients. Patient studies in the long-and short-axis views were compared with results from angiocardiography, with nearly identical findings.

Two- and Three-Dimensional CT Ventriculography

“…Electron beam CT with a time resolution of 50-100 msec per slice is useful to evaluate coronary arteries [1][2][3][4]. Cine CT reveals heart contraction [5][6][7][8]. However, electron beam CT is not practical in the clinical setting because of its high cost and limited availability.…”
