1 From the Division of Image Processing (B.P.F.L., R.J.v.d.G., J.H.C.R.), Department of Radiology (H.J.L.), Leiden University Medical Center, Bldg 1 C2-S, Albinusdreef 2, PO Box 9600, 2300 RC Leiden, the Netherlands; and Interuniversity Cardiology Institute of the Netherlands, Utrecht, the Netherlands (H.W.M.K., H.J.C.R.). Received December 22, 2000; revision requested February 5, 2001; revision received March 29; accepted May 14. Address correspondence to J.H.C.R. (e-mail: j.h.c.reiber@lumc.nl).

The authors compared an automated observer-independent acquisition planning method for short-axis multisection multiphase cardiac magnetic resonance imaging studies with conventional manual image planning. Systematic and random differences and reproducibility of left ventricular function measurements and image geometry were evaluated in five healthy adult volunteers and 20 patient studies. Results with the automated planning method were as accurate and reproducible as those with the manual planning method.
