Echo\u2010planar imaging (PI) can, however, be performed with a temporal resolution (30\u201350 msec) comparable to that of echocardiography. The authors evaluated the feasibility of real\u2010time imaging of cardiac valve motion with ultrafast MR techniques. Eight healthy volunteers and three patients with mitral stenosis and re\u2010 gurgitation were studied with a 1.5\u2010T whole\u2010body im\u2010 ager. Two different EPI sequences were assessed: a standard single\u2010shot gradient\u2010echo EPI (GEPI) SCquence and a fast imaging technique based on multiple\u2010shot EPI with interleaved k\u2010space acquisition (IGEPI). Fat\u2010suppressed images with an in\u2010plane resolution of 3.7 \u00d7 3.7 mm were obtained equally spaced through the cardiac cycle. Half\u2010k\u2010space acquisition was used. Morphologic evaluation was superior with IGEPI, owing to the better intracavitary signal homogeneity (<jats:italic>P<\/jats:italic> \u2264 0.01). and the mitral valve leaflets were easier to identify on systolic images. IGEPI provided adequate valve visibility in all three
