Abstract

PURPOSE
The purpose of this study is to evaluate the usefulness of fat suppression technique for MR imaging of the knee.
MATERIALS AND METHODS
Twenty-eight knees of 26 patients were imaged at a 1. 5 T MR system. Sagittal and coronal T2-Weighted spin echo images (SET2) and sagittal fat suppression SET2(FSSE) were obtained in all cases. We used a chemical shift imaging method for fat suppression. We compared FSSE with SET2 in terms of the conspicuity of lesions of menisci, cruciate ligaments, cartilage, bone and soft tissue of the knee.
RESULTS
Meniscal lesions were detected on FSSE and SET2 as well. FSSE depicted the lesion more conspicuously in 6 cases. For the depiction of ACL tear, SET2 was superior to FSSE in 5 cases. FSSE was better for the visualization of the normal structure of cartilage and it also depicted the cartilaginous lesions more conspicuously in 3 cases. Though bone bruise could be detected on both techniques, FSSE was better.
CONCLUSION
FSSE could provide the improved delineation of menisci, cartilage, bone bruise and other soft tissues except the injuries of anterior cruciate ligament. Although FSSE is a reliable method, it can not replace SET2. It may be used as a complemental method in the imaging of the knee.
