The purpose of this study was to compare short inversion time inversion recovery (STIR) fast spin‐echo (FSE), and fat‐saturated T2‐weighted FSE sequences in terms of uniformity of fat suppression and lesion conspicuity for magnetic resonance (MR) imaging of the neck and thorax. STIR FSE and fat‐saturated T2‐weighted FSE images were scored for uniformity of fat suppression ( n = 40) and lesion conspicuity ( n = 35). Five‐point rank score analyses were utilized by three experienced radiologists. The mean scores of STIR and fat‐saturated FSE techniques for uniformity of fat suppression were 4.3 and 2.3, respectively ( P < 0.0001). The mean scores of STIR and fat‐saturated FSE techniques for lesion conspicuity were 4.2 and 3.5, respectively ( P < 0.0001). Insufficient fat suppression was prominent in the mandible, supraclavicular region, anterior mediastinum, epipericardial fat, and subdiaphragmatic fat. In addition, fat‐saturated T2‐weighted FSE showed inadvertent water suppression in 25%. The STIR FSE technique was superior to the fat‐saturated FSE technique for cervical and thoracic MR imaging. J.
