“…FSE imaging techniques allow for the acquisition of high-resolution images in a relatively short amount of time while imparting increased contrast to the cartilage abnormalities. Also, of clinical importance, FSE imaging techniques are valuable pulse sequences in the diagnostic evaluation of other intraarticular structures including menisci, ligaments and subchondral bone [4][5][6]. As such, intermediate-and T2-weighted fast spin-echo imaging sequences, with and without fat suppression, have been advocated in the assessment of articular cartilage integrity [7][8][9][10].…”

Diagnostic performance of in vivo 3-T MRI for articular cartilage abnormalities in human osteoarthritic knees using histology as standard of reference

The purpose of this study was (1) to evaluate the sensitivity, specificity and accuracy of sagittal in vivo 3-T intermediate-weighted fast spin-echo (iwFSE) sequences in the assessment of knee cartilage pathologies using histology as the reference standard in patients undergoing total knee replacement, and (2) to correlate MR imaging findings typically associated with osteoarthritis such as bone marrow edema pattern (BMEP) and cartilage swelling with histological findings. Tibial plateaus and femoral condyles of eight knees of seven patients were resected during surgery, and sagittal histological sections were prepared for histology. Preoperative MRI findings were compared to the corresponding region in histological sections for thickness, surface integrity and signal pattern of cartilage, and histological findings in areas of BMEP and swelling were documented. The overall sensitivity, specificity and accuracy were 72%, 69% and 70% for thickness, 69%, 74% and 73% for surface and 36%, 62% and 45% for intracartilaginous signal pattern.

MRI using fatsaturated iwFSE sequences showed good performance in assessing cartilage thickness and surface lesions, while signal changes of cartilage were not suited to characterize the severity of cartilage degeneration as validated by histology.

“…Clinical examination can raise suspicion of ligamentous injury, but MRI is the noninvasive imaging modality of choice for the evaluation of overall knee pathology [15]. MRI accuracy is comparable to that of diagnostic arthroscopy [6,7], and MRI also allows assessment of the internal architecture of the knee. It can distinguish partial from complete rupture and evaluate the knee for associated injuries.…”

This study compares MRI with examination under anaesthesia to surgical findings in evaluating soft tissue injuries in acute multi-ligament knee trauma. Preoperative MRI was done for 44 patients who underwent surgery for grade III ACL and grade III medial collateral ligament (MCL) injury. In 21 cases both ACL and MCL were treated surgically, but in 23 only ACL. Intra-operative and MRI findings were compared. Accuracy of MRI for medial meniscal tears was 88.6%, sensitivity 80%, and specificity 91.2%; accuracy for lateral meniscal tears was 72.7%, sensitivity 55% and specificity 87.5%. Accuracy and sensitivity for severity of ACL tear was 93.2% and of MCL tear 86.4%. In 88.6% of the knees, bone bruises were visible, with anterolateral femoral and posterolateral tibial bone bruise being the most common. MRI revealed no chondral lesion, but arthroscopy revealed 11. In combined ACL-MCL ruptures, the incidence of concomitant injuries is high and the injuries are best detected with MRI.

“…This correlates well with various previous studies in literature. [6,7,9,10,18,19] Discordant appearance of ACL (when one MR sequence shows disrupted or poorly seen ACL fibres and other sequences show intact ACL fibres) and partial ACL tears were not reported in this study, because previous studies such as Smith et al [20] and Umans et al [21] have proved that in these cases ACL was normal when seen on arthroscopy. Thus, overall accuracy of the MRI in our study improved.…”

BACKGROUNDMRI is an excellent imaging modality for assessing internal derangement of the knee. Its non-invasive nature, excellent soft tissue contrast and no radiation risk makes MRI a boon in knee imaging. The aims of the study are-1. To know the occurrence of meniscal and ligament injuries following knee injury. 2. To evaluate diagnostic performance of MRI following knee injury in correlation with arthroscopy.
