“…10). Ultimately, fibrous pannus results from continued synovial proliferation, which exhibits little to no vasculature and depicts low signal intensity on all sequences [33]. Pannus within erosions shows intense enhancement on post-contrast sequences, which enable its differentiation from effusion in the knee [34].…”

The majority of abnormal findings or lesions on T2-weighted fast spin-echo (FSE) magnetic resonance imaging (MRI) are hyperintense due to increased perfusion or fluid content, such as infections, tumours or synovitis. Hypointense lesions on T2-weighted images (both fat-suppressed and non-fat-suppressed) are less common and can sometimes be overlooked. Such lesions have limited differential diagnostic possibilities, and include vacuum phenomenon, loose body, tenosynovial giant cell tumour, rheumatoid arthritis, haemochromatosis, gout, amyloid, chondrocalcinosis, hydroxyapetite deposition disease, lipoma arborescens, arthrofibrosis and iatrogenic lesions. These lesions often show characteristic appearances and predilections in the knee. In this article, the authors describe the MRI features of hypointense T2 lesions on routine knee MRI and outline a systematic diagnostic approach towards their evaluation. Key Points • Hypointense lesions on T2 images (T2 Dark Lesions) encompass limited diagnostic possibilities. • T2 Dark lesions often show characteristic appearances and predilections in the knee. • A systematic diagnostic approach will help radiologists make the correct diagnosis.

“…A few authors have reported on the dynamic MR imaging by using the MR contrast agen t. The synovial pannus showed the rapid and marked increse of signal intensity(9, 1 이 . The usefulness of the MR imaging of the rheumatoid arthritis have not been investigatd for the hand or wrist but the knee , even though the hand and/or wrist joints are more frequently invloved than the knee 이 n t. Rominger and his collegue (6) suggested that a spoiled gradient -recalled acquisition in the steady state (SPGR) with fat suppression was the best pulse sequence for the evaluation of inflammation and erosions in rheumatoid hand and wrist. Their study had a limitation of spatial resolution , because they used a field of view of 16 cm .…”

Purpose: To evaluate the optimal pulse sequences in the detection of erosions and forthe discri mination ofthe effusion from pannus. Materials and Methods: MR studies were performed in thirteen patients with clinical diagnosis of rheumatoid arthritis. We used a 1.5T MR unit with single or dual3 inch coi l. We compared coronal images at the same location , obtained with pulse sequences of T2, T2 with fat saturation, and postcontrast T1 with fat suppression. Erosions were assessed by comparing the count of the numbers of erosions depending on each imaging method. A four point scoring systems was used for the comparison of conspicuity of lesion.Results : T2WI with fat su ppression and postcontreat T1 WI with fat suppresison were better than conventiona I T2WI in the detection of erosions. The pa nnus had a heterogeneous signal on T2WI, some of which were enhanced after the intravenous injection of MR contrast a gents.Conclusion : We suggest that the fat suppression T1 WI with enhacnement or the fat suppression T2WI were better than conventional T2WI for detecting both bone erosion and pannus . The postcontrast MR imaging may often be helpul in distinguishing pannus from theeffusion .

“…A prerequisite for sensitivity to change is that the measure being considered is reproducible [ Magnetic Resonance Imaging MRI allows assessment of all the structures involved in arthritic disease (ie, synovial membrane, intra-and extraarticular fluid collections, cartilage, bone, ligaments, tendons, and tendon sheaths) [2,4,29,[51][52][53]. It has been shown to be more sensitive than clinical examination and X-ray for detection of inflammatory and destructive joint changes in early RA.…”
