| 摘 要： | 目的：探讨MR软骨成像最佳序列。方法：选20例正常腕关节，进行T1WI，T2WI，T1W／SPIR，T2W／SPIR，T1W／SPIR增强扫描，测量各序列信噪比强度进行比较，并进行统计学检验。结果：T1WI及T2WI信噪比较低，在MR图像上呈低信号。T1W／SPIR信噪比明显高于其它序列信噪比，在MR图像上呈高信号，增强扫描无强化，差异有统计学意义。结论：T1W／SPIR序列对软骨信号敏感，若结合T1WI，可对软骨病变作出定性诊断。

| Abstract: | Objective To explore the optimal MR imaging sequence for cartilaginous lesions.Methods Wrist joints in 20 normal volunteers were examined by T1WI,T2WI,T1W/SPIR,T2W/SPIR,and enhanced T1W/SPIR to measure and to compare the signal noise ratio(SNR)from each MR sequence.Then the statistic tests for the SNR data were performed.Results The SNR of cartilage on T1WI and T2WI was lower and cartilages were hypointense on MR imaging,while the SNR of cartilage from T1WI/SPIR was higher significantly than that from any other MRI sequences.The differences between varied sequences had statistic significance.Conclusion T1WI/SPIR Sequence is more susceptive to cartilage,if combine with T1WI,it can make the qualitative diagnosis of cartilaginous lesions. |
