Use of the short inversion time inversion recovery (STIR) sequence in magnetic resonance (MR) imaging of the liver is illustrated in 20 patients. The sequence provides high contrast images of the liver with relatively little degradation due to motion. Lesions appeared more extensive than with X-ray CT in 14 cases and equal in six. Additional areas of presumed atrophy, fatty infiltration, edema, or vascular insufficiency were only seen with MR. The STIR sequence may be valuable in screening of the liver for metastatic disease.
20例患者的肝脏磁共振成像采用了短反转时间反转恢复（STIR）序列。该序列能提供肝脏的高对比度图像，且因运动导致的图像质量下降相对较小。14例患者中，病变在该序列下显示的范围比X线CT显示的更广泛，6例两者显示范围相同。仅在磁共振成像中发现了推测的萎缩、脂肪浸润、水肿或血管供血不足的其他区域。STIR序列在肝脏转移性疾病筛查中可能具有重要价值。
