摘要

Background

The ankle joint is among the most frequently injured joints in sports and recreational activities. This work aimed to evaluate the additive role of MR T2 mapping to routine magnetic resonance imaging (MRI) to evaluate the early cartilage degeneration in the ankle joint.

Methods

One hundred and twelve patients who were referred to the radiodiagnosis department were included in this retrospective case–control research. The 112 cases were split into 30 volunteers (21 females, 9 males) as a control group and 82 patients (59 females, 23 males) who clinically presented with ankle discomfort; in the mid-sagittal picture, the ankle joint’s articular cartilage was separated into anterior, middle, and posterior zones. It was evaluated using qualitative (color) and quantitative (T2 value and curve) assessments.

Results

There were significantly higher means of the anterior, middle, and posterior zones T2 mapping values in the patients group than in the control group. Likewise, anterior zone abnormality, middle zone abnormality, and posterior zone abnormality were significantly higher than control group showing the absence of any abnormalities in the studied zones.

Conclusions

The addition of a T2 mapping of the ankle cartilage sequence to a routine MR ankle protocol improved sensitivity and accuracy in the detection of early degenerative changes in the ankle joint.
