“…Kijowski et al [18] found that a 3D FSE sequence had significantly higher sensitivity but significantly lower specificity for detecting 189 surgically confirmed cartilage lesions within the knee joint. In addition, studies performed by Kudo et al [21] and Milewski et al [16] showed similar diagnostic performance of 2D FSE and 3D FSE sequences for detecting smaller numbers of cartilage lesions in patients with arthroscopic correlation. Studies comparing 3D steadystate free-precession [15,19,22] and gradient recall-echo acquired in the steady-state [20] sequences with 2D FSE sequences have also shown similar sensitivities and specificities for detecting surgically confirmed car-tilage within the knee joint, indicating that performance issues are not unique to 3D FSE sequences.…”

“…Despite the clear theoretic advantages, the use of 3D sequences has not translated into a substantial improvement in diagnostic performance for detecting cartilage lesions within the knee joint in multiple clinical studies [15][16][17][18][19][20][21]. In most of these studies, the sensitivity for identifying cartilage lesions using both 2D FSE and 3D sequences is highest on the thick articular surface of the patella and lowest on the lateral tibial plateau, where the curved articular surface is prone to partial volume averaging and imaging artifacts.…”

“…56 In the knee, such images with 6-mm isotropic resolution have been shown to be similar to conventional 2D TSE sequences for characterization of meniscal tears, and superior to 2D techniques for the detection of flap tears. 57,58 Other results in the shoulder have been equally promising: In one study, 3D TSE sequences demonstrated near-perfect concordance with 2D TSE and decreased examination time by almost 40%. 59 Three-dimensional imaging techniques in combination with MR arthrography have also proven to be suitable substitutes for the evaluation of bony Bankart lesions and glenoid bone loss in anterior shoulder instability.…”

The past 50 years have transformed imaging of the joints. Whereas musculoskeletal imaging consisted predominantly of conventional radiography when Investigative Radiology was founded as a journal, the arrival of new imaging modalities, and above all, the introduction of magnetic resonance imaging, resulted in a paradigm shift: In addition to visualizing osseous structures, now the detailed depiction of soft tissue structures became part of routine clinical imaging and had a major impact on understanding pathophysiology and patient treatment. This article analyzes the patterns of innovation that were essential for the transformation of musculoskeletal radiology. Furthermore, state-of-the-art joint imaging is described through 9 key concepts, including both cutting-edge clinical applications as well as topics at the forefront of musculoskeletal research. Eventually, emerging trends are outlined that will likely shape musculoskeletal radiology in the next decades. The past 50 years have transformed imaging of the joints.

“…T2 mapping, a sequence sensitive to T2 prolongation induced by cartilage degeneration, has been considered as effective in detecting very early patellar cartilage lesions although the technique is time consuming and has lower resolution (2,3,6,17). We currently use these two sequences in our daily practice for imaging of the patellar cartilage.…”

A new MRI grading system for chondromalacia patellae

Background Chondromalacia patellae is a very common disorder. Although magnetic resonance imaging (MRI) is widely used to investigate patellar cartilage lesions, there is no descriptive MRI-based grading system for chondromalacia patellae. Purpose To propose a new MRI grading system for chondromalacia patellae with corresponding high resolution images which might be useful in precisely reporting and comparing knee examinations in routine daily practice and used in predicting natural course and clinical outcome of the patellar cartilage lesions. Material and Methods High resolution fat-saturated proton density (FS PD) images in the axial plane with corresponding T2 mapping images were reviewed. A detailed MRI grading system covering the deficiencies of the existing gradings has been set and presented on these images. Two experienced observers blinded to clinical data examined 44 knee MR images and evaluated patellar cartilage changes according to the proposed grading system. Inter- and intra-rater validity testing using kappa statistics were calculated. Results A descriptive and detailed grading system with corresponding FS PD and T2 mapping images has been presented. Inter-rater agreement was 0.80 (95% confidence interval [CI], 0.71-0.89). Intra-rater agreements were 0.83 (95% CI, 0.74-0.91) for observer A and 0.79 (95% CI, 0.70-0.88) for observer B (k-values). Conclusion We present a new MRI grading system for chondromalacia patellae with corresponding images and good inter- and intra-rater agreement which might be useful in reporting and comparing knee MRI examinations in daily practice and may also have the potential for using more precisely predicting prognosis and clinical outcome of the patients.
