“…18 Previous studies have reported that 3D VISTA is comparable or superior to 2D FSE for the evaluation of the nerve root in the cervical spine and that it has high sensitivity and specificity in the evaluation of meniscal tears and the ACL. 18,20,21 Park et al 13 reported that the SNRs and CNRs are higher for 3D VISTA than for 2D FSE in their study on the anterior talofibular ligament (ATFL) of the ankle joint. In the current study, the mean SNR of the PCL was lower on 3D VISTA than on 2D FSE, whereas the mean CNR was higher for 3D VISTA than for 2D FSE.…”

Results: The mean contrast-to-noise ratio was significantly higher for 3D VISTA than for 2D FSE. The two imaging modalities did not differ significantly in anatomical identification ability, with the exception of margin sharpness, which was inferior for 3D VISTA with Reader 2 ( p 5 0.038). When we classified the diagnoses of PCL injury as normal or abnormal, there were no significant differences in sensitivity, specificity or accuracy between the PCL view of 3D VISTA and 2D FSE images ( p . 0.05). Conclusion: 3D VISTA had a superior contrast-to-noise ratio than 2D FSE and similar image quality in the evaluation of the PCL. The PCL view of 3D VISTA has the same diagnostic ability as 2D FSE in the diagnosis of PCL injury and can thus replace 2D FSE. Advances in knowledge: The oblique coronal view 3D VISTA MRI has similar diagnostic ability to 2D FSE in the diagnosis of PCL injury, and therefore 3D VISTA image can replace 2D FSE.

“…The study by Rubin et al reported a fall in diagnostic specificity for ligamental tears with multiple ligament injuries [7]. Magnetic resonance (MR) imaging is sensitive and specific in the diagnosis of internal derangements of the knee [8] [9]. In our study of Internal Derangement of Knee, we studied 120 patients of which 48 were left knee joint and 72 were right knee joint.…”

Introduction: Internal derangement of the knee is a blanket term used to cover a group of disorders involving destruction of the normal functioning of the ligaments or cartilages. MRI provides excellent soft tissue contrast and is capable of evaluating the soft tissue and bony structures in multiple imaging planes which provide significant advantage in IDK. Methods and Materials: A prospective study of hundred twenty patients who underwent MRI for the diagnosis of internal derangement of knee between the period January 2013 and January 2015 was conducted. All the patients gave a history of knee joint pain following trauma and clinically suspected to have meniscal and ligament tears. Patients were evaluated using Philips intera R 11 1.5 T with pulsar gradient system using a sensor extremity coil. Results: Commonest lesion detected in our study was ACL tear followed by meniscal tear and medial collateral ligament injury. The most common sign of cruciate ligament injury was hyper intensity in the ligament. Grade 3 was the most common grade of meniscal tear. Conclusion: MRI is unique in its ability to evaluate the internal structure as well as the surface of the meniscus. Many anatomical variants can mimic a tear on MRI. MRI is an excellent non invasive modality for imaging the knee.

“…Yoon et al [14] performed TSE PDW MRI with 1 mm thickness and observed inadequate tissue contrast because of the presence of a certain degree of image degradation during the multiplanar reconstruction process owing to nonisotropic images. Jung et al [22] acquired isotropic axial multiplanar reconstruction images by 3 T MRI. However, 3D volume techniques have some limitations, such as the presence of a higher signal intensity in normal menisci than that on the spin-echo sequence and more widespread signal increase in the degenerated menisci [4].…”

Objective: To evaluate the diagnostic efficacy of thin-slice (1 mm) axial proton density-weighted (PDW) MRI of the knee for meniscal tear detection and classification. Methods: We prospectively assessed pre-operative MR images of 58 patients (41 males, 17 females; age range 18-62 years) with arthroscopically confirmed meniscal tear. First, we evaluated the performance of the sagittal and thin-slice axial MR images for the diagnosis of meniscal tears. Second, we compared the correlation of tear types presumed from sagittal and axial MRI with arthroscopy and tear classification from axial MRI. Tears were classified on the sagittal plane and the axial plane separately. The diagnostic performance and tear classification were compared statistically with arthroscopy results, which is accepted as the standard of reference. Results: 8 of 58 patients were removed from the study group because they had complex or degenerative tears. A total of 62 tears were detected with arthroscopy in 50 patients. On the sagittal images, sensitivity and specificity values were 90.62% and 70.37%, respectively, for medial meniscus tears and 72.73% and 77.14%, respectively, for lateral meniscus tears. The corresponding values for axial images were 97.30% and 84.00%, respectively, for medial meniscus tears and 95.65% and 80.50%, respectively, for lateral meniscus tears. There was no significant difference in tear classification between the arthroscopy results and the thin-slice axial PDW MRI results (p.0.05). Conclusion: thin-slice axial PDW MRI increases the sensitivity and specificity of meniscal tear detection and especially classification, which is important for surgical procedure decisions.
