Background: Cartilage mapping using Magnetic Resonance Imaging T2 is a functional scanning procedure without invasion delivering cartography of the cartilage T2 relaxation time without using of any contrast. It is tissue anisotropy sensitive, and compositional data on the collagen network of cartilage, content of water and concentration of proteoglycans are provided by it. This study used MR scanning technique to assess the T2 mapping sequence role in diagnosis of articular cartilage lesions of knee joint. Patients and Methods: This prospective trial was done to utilize sagittal T2 mapping sequence for assessment of articular cartilage of knee joint on 1.5 T MR. The material of this study included thirty (30) patients. The study included 24/30 cases presented by knee pain, 6/30 cases presented by knee pain following trauma, 10/30 cases presented by limitation of movement and 7/30 cases presented by knee swelling. As each patient had a single conventional MRI examination of the knee followed by a single sagittal T2 maps, 30 MRI examinations and 30 corresponding T2 maps were analyzed. Results: The addition of sagittal T2 maps to standard views improved accuracy in diagnosing cartilage affection in early osteoarthritis. there are 69 (57.5%) lesions diagnosed as grade 0 by MRI only VS 24 (20%) lesions diagnosed as grade 0 by MRI with T2 mapping sequence and 34 (28.3%) lesions diagnosed as grade 1 by MRI only VS 77 (64.2%) lesions diagnosed as grade 1 by MRI with T2 mapping sequence. there is 46 (38.3%) lesions diagnosed as grade 1a by MRI with T2 mapping sequence which diagnosed grade 0 by MRI only. Conclusions: This imaging plane seems to provide a useful addition to standard MR imaging when osteoarthritis is suspected specially among the young population.

Abstract Background This work aims at elucidating the role of adding complementary T2 mapping to the routine 1.5 Tesla MRI protocol in the articular knee cartilage assessment for early detection of osteoarthritis, and also, comparing the articular cartilage thickness and T2 relaxation times between the case and control groups regarding knee compartments affection. Results Both sensitivities and specificities were 73.3% and 100%, respectively, for the standard MR protocol alone and 96.7% and 90% after adding the T2 mapping to the standard MR protocol that leads to significant sensitivity improvement. A comparison between patients and controls as regards T2 values showed a highly statistically significant difference (independent T test, p <0.001). Conclusion A combination of both morphological and T2 mapping MRI, together with clinical evaluation represents a desirable multimodal approach to the diagnosis of osteoarthritis. In the early detection of osteoarthritis, adding T2 mapping sequence to the standard MR protocol at 1.5 Tesla improved sensitivity from 73.3 to 96.7%.

Abstract Background The predictive value of the new imaging sequences, especially T2 mapping in assessment of articular cartilage abnormalities of the medial knee compartments in patients with medial knee pain. The purpose of this study is to evaluate the additional value of T2 mapping over using a baseline standard knee MRI to detect cartilage lesions of the medial compartments in patients representing with medial knee pain. Results The study included 60 patients presented with medial knee pain, where divided into two groups ; control group (20 volunteers) with age range from 19 to 41 years old 26.80 ± 8.05 (mean ± SD) and patients (40 candidates) with age range from 13 to 57 years old with a mean age 33.00 ± 14.1 (mean ± SD). Conclusion On adding T2 mapping sequence to the routine MRI of the knee, the sensitivity for detecting knee cartilage lesions was increased, especially in the detection of early cartilage degeneration at the medial compartment. Compositional MR imaging including T2 mapping plays an important role in the assessment of early and potentially reversible cartilage damage especially among the young population.
