Purpose
The purpose of this study is to examine the topographic differences of talar cartilage with talar osteochondral lesion using delayed gadolinium enhanced magnetic resonance imaging ( d GEMRIC).
Therefore we can evaluate the topographic differences and degree of cartilage degeneration in patients having talar osteochondral lesion.
Methods and Materials
Ten ( 10) patients with talar osteochondral lesion and 10 healty volunteers were evalulated using d GEMRIC at 3 Tesla ( Achieva; Philips,
Netherland) .
Differences in post-contrast T1 relaxation of cartilage between groups and locations were evalulated at 2 separate locations ( lesion side- contralateral to lesion side as front or rear)
Results
The mean T1 relaxation times were measured at different parts of the cartilage.
It was compared in patient and control groups with topographic measurement of talar cartilage.
( Fig.
1) The value of mean relaxation time in patient group was found lower than control group.
( Fig.
2) All patient had osteochondral lesion in front part of the cartilage.
The values of mean relaxation time was found lower in front part in patient group than the control group.
( Fig.
3) The values of mean...
Conclusion
D GEMRIC may be a useful method to evaluate degenerative changes in talar cartilage at the osteochondral lesion side as well as the degeneration level in different localisation of the cartilage.
This property makes it superior to other conventional cartilage imaging modalities. Hence it can be used safely in case of suspect of cartilage degeneration.
It can also be used other degerative disorders related to cartilage most commonly at knee.
It can be used commonly in the future researches to evaluate cartilage degeneration in other...
