OBJECTIVE We evaluated the precision of helical MDCT for the quantification of mitral valve stenosis (MVS) compared with transthoracic echocardiography (TTE) and cardiac catheterization. MATERIALS AND METHODS A total of 28 patients with MVS of differing severity underwent an ECG-gated contrast-enhanced MDCT scan. The mitral valve area (MVA) was determined(More)
OBJECTIVE We sought to determine the comparability of multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) for measuring the aortic valve orifice area (AVA) and grading aortic valve stenosis. MATERIALS AND METHODS Twenty-seven individuals, among them 18 patients with valvular stenosis, underwent AVA planimetry by both MSCT and MRI.(More)
PURPOSE We sought to determine the accuracy of multislice spiral computed tomography (MSCT) for assessing of aortic valve stenosis and to establish threshold values of the planimetric aortic valve orifice area (AVA) that best separate between different grades of stenosis severity. MATERIALS AND METHODS A total of 202 patients (among them 160 patients with(More)
