“…However, it is noteworthy that Vogrig et al 53 reported discordant findings at 1.5 T and showed that synthetic morphological contrasts derived by “Synthetic MRI” resulted in a lower diagnostic reader performance than assessing conventional images. Boudabbous et al 54 came to a similar conclusion and stated that “Synthetic MRI” shows great promise but has limitations due to artifacts and a lower detection rate for cartilage lesions and ligament injury at 1.5 T field strength.…”

This review summarizes the existing techniques and methods used to generate synthetic contrasts from magnetic resonance imaging data focusing on musculoskeletal magnetic resonance imaging. To that end, the different approaches were categorized into 3 different methodological groups: mathematical image transformation, physics-based, and data-driven approaches. Each group is characterized, followed by examples and a brief overview of their clinical validation, if present. Finally, we will discuss the advantages, disadvantages, and caveats of synthetic contrasts, focusing on the preservation of image information, validation, and aspects of the clinical workflow.

“…Lately, different MR sequences such as T1r, T2 and dGEMRIC has been developed for evaluating changes in cartilage composition before morphologic changes can be appreciated by standard MR imaging (MRI) [ 27 ]. In particular, studies linking variations in T2 values and variations of water and collagen in cartilage have shown significant differences between symptomatic and asymptomatic patients with arthrosis [ 28 , 29 ].…”

Background Patellar femoral chondropathy (FPC) is a common problem in patients undergoing anterior cruciate ligament reconstruction (ACL-R) surgery, which, if left untreated, predisposes to arthrosis. Magnetic resonance imaging (MRI) is the non-invasive gold standard for morphological evaluation of cartilage, while in recent years advanced MRI techniques (such as T2 mapping) have been developed to detect early cartilage biochemical changes. This study evaluates the different onset of early PFC between B-TP-B and HT through T2 mapping. Secondly, it aims to assess the presence of any concordance between self-reported questionnaires and qualitative MRI. Materials and methods 19 patients enrolled were divided into two groups based on the type of intervention: B-PT-B and HT. After a median time of 54 months from surgery, patients were subjected to conventional MRI, T2 mapping, and clinical-functional evaluation through three self-reported questionnaires: Knee Injury and Osteoarthritis index (KOOS); Tegner Lysholm Knee Scoring Scale; International Knee Documentation Committee (IKDC). Results There is not statistically significant difference in the comparison between the two MRI techniques and the two reconstructive techniques. KOOS and Tegner Lysholm scales showed significant agreement with MRI results on the grading of chondropathy. Conclusions There are no differences between B-TP-B and HT techniques in the early development of PFC detectable through non-invasive methods. Due to the large reduction in the frequency of physical activity following ACL-R and the finding of mild PFC (grade I and II) in a substantial proportion of patients, after a relatively short period from ACL-R, all patients should undergo conservative treatment.
