1 From the Departments of Radiology (O.B.V., J.A., P.L.), Biostatistics (J.C.), and Cardiology (D.D.), Université René Descartes, Hôpital Cochin, 27 rue du Fg Saint Jacques, 75679 Paris Cedex 14, France; Service Hospitalier Frederic Joliot, Orsay, France (P.G.C.); and GE Medical Systems, Buc, France (C.A., P.L.R.). Received June 27, 2000; revision requested August 7; revision received September 14; accepted October 11. Address correspondence to O.B.V. (e-mail: olivier.vignaux@cch.ap-hop-paris.fr).

A conventional T1-weighted spin-echo (SE) magnetic resonance (MR) imaging sequence was compared with breath-hold and non–breath-hold half- Fourier single-shot fast SE MR sequences with black-blood preparation and high spatial resolution for imaging of various cardiac diseases. The optimized single-shot fast SE sequence provided better or equal image quality in less time. Breath-hold and non–breath-hold single-shot fast SE sequences may replace the conventional T1-weighted SE sequence for first-line cardiac MR imaging.
