Aiming for a shorter rheumatoid arthritis MRI protocol: can contrast-enhanced MRI replace T2 for the detection of bone marrow oedema?

Abstract: • Bone marrow oedema scores are equal on T2 and T1-Gd-chelate enhanced sequences. • Agreement between scores based on T2 and T1-Gd-chelate images was excellent. • Sensitivity and specificity for presence of bone marrow oedema were high. • A short protocol without T2 images suffices in rheumatoid arthritis patients.

“…9,21 Contrast medium is not recommended for the diagnosis of SpA-associated sacroiliitis. 9,21,[23][24][25][26][27] However, it is of diagnostic importance for the differentiation of diagnoses other than axSpA, especially in the clinical setting of an infection and abscess formation. 21 Recently in a viewpoint article, some practical MRI concepts were addressed including the background theory of MRI acquisition, MRI sequences, and interpretation of signal intensities.…”

“…After 6–11 minutes, contrast reaches the synovial fluid, obscuring the synovium / fluid interface (1, 13, 14) . Imaging is then best performed between these times.…”

“…The RA MRI Scoring (RAMRIS) system, a standardized semi-quantitative assessment of inflammatory soft tissue and destructive bone alteration, recommends that imaging should include T1-weighted sequences primarily to assess erosions, T2-weighted FS or STIR to evaluate BME and post-gadolinium T1Gd in combination with non-contrast T1-weighted images to evaluate synovitis and tenosynovitis [10, 11]. The RAMRIS does not describe the use of FS for post-contrast T1.…”

“…The RAMRIS does not describe the use of FS for post-contrast T1. In practice, however, it is commonly used to increase the visibility of enhancement and to differentiate enhancement from fatty tissue on fast spin echo sequences which exhibit a high signal of fat [11]. Thus, the standardised use of fat suppression in T1Gd sequence aids in identifying enhancing BME in the fatty bone marrow.…”
