1 H double quantum filtered (DQF) imaging has been shown to highlight tendons. In this work the DQF magnetic resonance imaging pulse sequence is extended to include slice selection. The short transverse relaxation time of the 1 H nuclear magnetic resonance in connective tissues, presents a stringent demand on the application of gradients and soft radiofrequency pulse lengths needed for slice selection. In the present work a slice selection pulse sequence is implemented by postponing the application of the slice refocusing gradient to the period after the last pulse just before the acquisition. Slice‐selective DQF images of rat lower leg and knee are given to demonstrate the efficacy of the technique. J. Magn. Reson. Imaging 2000;11:336–341. © 2000 Wiley‐Liss, Inc.
