摘　　要：目的:探讨MR I间接膝关节造影诊断半月板撕裂的价值。材料和方法:选取MR I平扫疑似半月板损伤32例,静脉注射常规剂量(0.1mmol/kg)与双倍剂量(0.2mmol/kg)造影剂(Gd-DTPA),运动后延时扫描。参照MR I平扫片对比两组不同浓度MR I关节造影表现。结果:两种不同浓度造影均可使半月板撕裂的高信号增加,以采用0.2mmol/kg造影效果较好。32个半月板,造影后确诊半月板撕裂18例(占56.3%),排除诊断8例(占25%),确诊和排除诊断合计占81.3%,6例可疑,可疑的6例经关节镜检查排除诊断3例。结论:对半月板损伤MR I平扫不能肯定诊断时,行间接膝关节造影对确定或排除诊断是十分必要的。0.1mmol/kg Gd-DTPA能达到诊断目的。Purpose： To explore the value of indirect MRI arthrography in diagnosing the meniscal tears of knee joint. Materials and Methods： Thirty-two patients with suspected meniscal tears in conventional MRI scans were injected Gd-DTPA with normal dose （0. 1mmol/ kg） or double dose （0.2 mmol/kg） respectively, then scanned after the articular genu motion. The two groups were compared while took the conventional MRI as reference. Results： Both the two dosage indirect MRI arthrography can enhance the signal of the meniscal tears although the double dose group showed much better. Within the 32 meniscuses, 18 cases （56, 3% ） were diagnosed as tears, 8 cases （25%） were excluded, 6 cases were suspected. Three cases in 6 teares suspected on MRI were excluded by arthroscopy. Conclusion： When the meniscal tears of knee joint were not sure on conventional MRI,the indirect MRI arthrography is very helpful to diagnose or exclude the meniscal tears.
