Abstract
from from June 2019 to July 2021, this pilot exploratory study was done to use axial or sagittal or coronal T2 mapping or all to visualize the articular cartilage of the knee on 3 T and 1.5 T MR Scanner using special advanced software to evaluate the effect of painful knee joint osteoarthritic changes on knee articular cartilage.
The material of this study included sixty (60) patients. The study included 16/60 (26.7%) cases presented by knee pain following direct trauma, 44/60 (73.3%) cases presented by knee pain following knee twisting. As each patient had a single conventional MRI examination of the knee followed by a single axial or coronal or sagittal T2 maps or all, 60 MRI examinations and more than 60 corresponding T2 maps were analyzed.
Firstly, the standard imaging planes of the knee were evaluated with focusing on its articular cartilage at different imaging sequences, and then axial, sagittal or coronal T2 maps or all were generated using a special software technique. Thereafter, these standard planes were evaluated together with T2 maps for the same regions, and articular cartilage was evaluated using color scale from orange to blue.
Intact articular cartilage was defined by the normal signal intensity in different pulse sequences with uniform thickness, while in T2 maps normal knee articular cartilage at different sites generally below 44 milliseconds which corresponds to the orange zone on the color scale in our study.
Summary & Conclusion
122
The addition of sagittal T2 maps to standard views improved accuracy in diagnosing cartilage affection in early osteoarthritic painful knee joint.
This imaging plane seems to provide a useful addition to standard MR imaging when osteoarthritis is suspected as a cause of painful knee joint especially among the young population. It also provides an excellent screening tool for athletes. It provides a good monitoring tool for osteoarthritis process.
