Abstract

This study was aimed at investigating the diagnostic value of MRI based on K-space data reconstruction algorithm for anterior cruciate ligament (ACL) injury of knee joint and the influencing factors of ligament injury. 96 patients with ACL injury of knee joint were selected, and they were randomly divided into two groups: group A (arthroscopy) and group B (MRI examination), and another 96 healthy volunteers in the same period were selected as the control group. The test results of each indicator were compared. The results showed that the signal-to-noise ratio (SNR) of SMASH algorithm was higher than that of sum of squares (SOS) algorithm. In group A, there were 66 positive and 30 negative tests, and in group B, there were 56 positive and 40 negative tests ( < 0.05). The intercondylar fossa width, the intercondylar fossa width index, and the ratio of tibial intercondylar eminence width to intercondylar fossa width in group B were lower than those in the control group ( < 0.05). Compared with the traditional SOS algorithm, SMASH algorithm can improve the image quality, reduce the impact of damage data on the final synthesis image, and improve the image SNR. In clinical work, the ratio of the width of tibial intercondylar eminence to the width of femoral intercondylar fossa can be measured by imaging data to evaluate the matching between tibial intercondylar eminence and femoral intercondylar fossa, so as to evaluate the risk of ACL rupture.

摘要

本研究旨在探讨基于 K 空间数据重建算法的 MRI 对膝关节前交叉韧带（ACL）损伤的诊断价值及韧带损伤的影响因素。选取膝关节 ACL 损伤患者 96 例，随机分为 A 组（关节镜）和 B 组（MRI 检查），同期选取 96 例健康志愿者作为对照组，比较各组各指标检测结果。结果显示，SMASH 算法的信噪比（SNR）高于和均方和（SOS）算法。A 组中 66 例阳性，30 例阴性；B 组中 56 例阳性，40 例阴性，差异均有统计学意义（<0.05）。B 组患者的髁间窝宽度、髁间窝宽度指数及胫骨髁间隆起宽度/髁间窝宽度比值均低于对照组，差异均有统计学意义（<0.05）。与传统 SOS 算法相比，SMASH 算法可提高图像质量，减少损伤数据对最终合成图像的影响，提高图像 SNR。在临床工作中，可通过影像学数据测量胫骨髁间隆起宽度与股骨髁间窝宽度的比值，评估胫骨髁间隆起与股骨髁间窝的匹配程度，从而评估 ACL 断裂的风险。
