Application and image feature analysis of MRI in diagnosis of femoral head necrosis
核磁共振诊断股骨头坏死的应用及影像特征分析

摘要

目的 在进行股骨头坏死患者诊断的时候，对核磁共振诊断方法的应用情况、影像特征予以分析研究。方法 在医院中选择60名股骨头坏死患者，根据不同的诊断方法将这些患者分为两个小组，每一组中的患者数量均为30名，其中一组患者是采用CT的方式来诊断，另一组患者是采用核磁共振的方式来诊断，两组患者被命名为CT组、核磁组。通过两组患者诊断结果、诊断分级的对比，就可以判断出核磁共振诊断方法临床应用的作用与价值。结果 在诊断结果上，核磁组患者的检出率更高；在诊断分级上，核磁组患者的分级结果更优。两组患者的结果之间存在明显的差异与不同。结论 对股骨头坏死疾病的诊断来讲，核磁共振方法的应用效果更强，应用价值更高，因此这种方法值得在临床上予以推广。

Abstract

Objective To analyze and study the application and imaging features of magnetic resonance imaging in the diagnosis of patients with femoral head necrosis.
Methods 60 patients with femoral head necrosis were selected in the hospital and divided into two groups based on different diagnostic methods. Each group had 30 patients, with one group diagnosed using CT and the other group diagnosed using MRI. The two groups of patients were named CT group and MRI group. By comparing the diagnostic results and grading of two groups of patients, the role and value of magnetic resonance imaging in clinical application can be determined.
Results In terms of diagnostic results, the detection rate of patients in the MRI group is higher; In terms of diagnostic grading, patients in the MRI group have better grading results. There are significant differences in the results between the two groups of patients.
Conclusion   For the diagnosis of femoral head necrosis disease, magnetic resonance imaging has a stronger application effect and higher value, so this method is worth promoting in clinical practice.
