Synovitis maps for the assessment of inflammatory diseases of the hand

Abstract: Objectives To compare accuracy and review times of FLASH-MRI-derived synovitis maps (SM) with conventional MR images (cMRI) in the assessment of articular synovitis and tenosynovitis of the hand. Methods 80 hands in 40 patients (mean age, 48 years; range, 15-72 years) were assessed for synovitis on cMRI and SM by two readers independently. Reporting times and diagnostic confidence (scale: 1=least, 5=most confident) were measured. Results from an assessment of a panel of senior musculoskeletal radiologists serv… Show more

“…However, in another study assessing cartilage lesions of the wrist, MRI had a high specificity, but low interobserver agreement [25]. A fair interobserver agreement was found for synovial lesions of the hand [26]. Finding an “active” osseous lesion in MRI is predominantly based on the prevalence of “bone marrow edema”, a pattern of ill-defined hyperintense signal on T2-weighted images.…”

“…There were other limitations in that study, such as the inclusion of patients with disease duration up to 24 months, which exceeds the currently accepted definition of early RA (34,35), and the focus on groups of tendons, masking potential findings for individual tendons. An interesting recent study of synovitis maps by Karlo et al (42) included tenosynovitis evaluation, but it addressed unspecified…”

“…The training requirements, interpretation time, and need for double reading make the RAMRIS synovitis score impractical for routine clinical use [122][123][124]. One proposed way to decrease observer times for semiquantitative rating is to create coronal, maximum intensity projections from dynamic or static contrast-enhanced images that provide a visual overview of the involved joints (and tendon sheaths) [125,126]. Although this technique usually involves first subtracting precontrast images, it can also be done without subtraction, allowing a time saving by eliminating the need to acquire a matching precontrast sequence (Fig.…”
