Abstract

In the first year of magnetic resonance imaging (MRI) scanning of the knee in the East Berkshire Health District, 175 patients were scanned and 79 of these subsequently had an arthroscopy performed. We found that MRI accurately demonstrated the pathology present in the knee, particularly for meniscal lesions, although it was less accurate for anterior cruciate and cartilage lesions. The relative costs of MRI scanning, arthroscopy and conservative treatment are compared. On the basis of this analysis we have worked out a protocol for the cost-effective use of MRI in imaging the knee. This protocol has reduced the number of arthroscopies performed, allowing us to expend resources on patients who would definitely benefit from arthroscopic surgery.

摘要

在东伯克郡健康区对膝关节进行磁共振成像(MRI)扫描的第一年,对175名患者进行了扫描,其中79人随后接受了关节镜检查。我们发现,MRI能够准确显示膝关节存在的病变,尤其是半月板损伤,不过对于前交叉韧带和软骨损伤的显示准确性稍差。比较了MRI扫描、关节镜检查和保守治疗的相对成本。基于此分析,我们制定了一项在膝关节成像中经济有效使用MRI的方案。该方案减少了关节镜检查的数量,使我们能够将资源用于肯定能从关节镜手术中受益的患者。
