膝关节内侧副韧带薄层断面与MRI解剖及其诊断价值

目的研究膝关节内侧副韧带薄层断面表现及其正常和损伤的MRI表现。方法分析内侧副韧带薄层断面标本解剖特点,对120例正常膝关节内侧副韧带及25例损伤病例MRI表现进行回顾性分析。结果薄层断面清晰显示膝关节内侧副韧带解剖特点,MRI与薄层断面具有很好对应性。MRI能够对内侧副韧带损伤进行准确分级。结论薄层断面与MRI能够清晰显示内侧副韧带的解剖学特点。横轴位MRI分级评价对内侧副韧带损伤的诊断和治疗具有重要价值。

The Study of Thin Slice and MRI of Medial Collateral Ligament and its Value in Injuries

Objective:To study thin slice of medial collateral ligament (MCL) and its normal and injured medial collateral ligament manifestations on MRI.Methods:Using the medial collateral ligament of Chinese Digitized Visible Human as a basis for cross-anatomy,MRI appearance of normal MCL in 120 cases were retrospectively reviewed and MRI findings of injured MCL in 25 cases were analysed.Results:The anatomy of MCL was clearly demonstrated on thin slice,the appearance of the MCL of the knee on MR images was correlated with corresponding anatomic slices and MCL injury was accurately graded on MRI.Conculsion:Three-layered anatomy of MCL can be observed on thin silice and MR images.Axial plane is important in the diagnosis of injured MCL and MR imaging in grading MCL injury of the knee is of important value in the diagnosis and treatment of the injuries.
