To compare conventional short inversion time inversion-recovery (STIR) with fast spin-echo (FSE) STIR techniques to evaluate suspected nontraumatic musculoskeletal abnormalities.
Thirty STIR and FSE-STIR examinations in 26 pediatric patients with suspected nontraumatic musculoskeletal abnormalities were prospectively evaluated. Qualitative (subjective) and quantitative (five-point rank score) analyses of the images were performed.
FSE-STIR was faster than STIR (mean, 2 minutes 25 seconds and 6 minutes 35 seconds, respectively). Fat suppression was slightly better with STIR. Image degradation due to motion was judged similar. Lesion contrast to muscle was slightly better with STIR than FSE-STIR, and lesion contrast to fat was equivalent. Qualitatively, lesion conspicuity was similar: All lesions were seen with both techniques.
FSE-STIR can replace STIR when an inversion-recovery fat-suppression sequence is desired. Considerable imaging time is saved.
比较传统短反转时间反转恢复（STIR）序列与快速自旋回波（FSE）STIR技术，以评估可疑的非创伤性肌肉骨骼异常。
前瞻性评估26例疑似非创伤性肌肉骨骼异常的儿科患者的30次STIR和FSE-STIR检查。对图像进行定性（主观）和定量（五点等级评分）分析。
FSE-STIR比STIR更快（平均分别为2分25秒和6分35秒）。STIR的脂肪抑制效果略好。因运动导致的图像退化情况被判定相似。STIR序列下病变与肌肉的对比度略优于FSE-STIR，而病变与脂肪的对比度相当。定性方面，病变的清晰度相似：两种技术均能显示所有病变。
当需要反转恢复脂肪抑制序列时，FSE-STIR可替代STIR。可节省大量成像时间。
