Diagnostic accuracy of wrist MR-arthrography protocol using iodinated contrast agent only in the detection of intrinsic wrist ligament and triangular fibrocartilage complex tears.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo determine the diagnostic accuracy of a wrist MR-arthrography (MR-A) protocol using iodinated contrast agent only compared to wrist diagnostic arthroscopy in the detection of tears of intrinsic ligaments and triangular fibrocartilage complex (TFCC). MATERIALS AND
methodsThis study retrospectively enrolled 39 patients who underwent MR-A using iodinated contrast agent only before arthroscopic examination between May 2019 and December 2021. For each patient, a resident (R1) and an experienced musculoskeletal radiologist (R2) independently reviewed the MR-A dataset. The performance in detecting and characterizing tears of intrinsic ligaments and TFCC was calculated against arthroscopic reports. Intra- and interrater agreements for MR-A were calculated too.
resultsPrevalence of ligament tear was 74% for scapholunate (SL) ligament, 51% for lunotriquetral (LT) ligament and 64% for TFCC. Wrist arthroscopy revealed cartilage lesions in 25.6%. Concerning SL tears, sensitivity, specificity, and accuracy of MR-A were 1.00, 0.70, and 0.92 (R1) and 0.90, 0.90, and 0.90 (R2). For LT tears, sensitivity, specificity, and accuracy were 0.90, 0.74, and 0.82 (R1) and 0.90, 0.84, and 0.87 (R2). Regarding TFCC tears, sensitivity, specificity, and accuracy were 0.80, 0.79, and 0.79 (R1) and 0.96, 0.86, and 0.92 (R2). Concerning SL tear characterization (partial versus complete tear), agreement between MR-A and arthroscopy was good (0.62 [0.42-0.83] for R1; 0.76 [0.60-0.91] for R2). Interobserver and intraobserver agreements for MR-A assessment were respectively good (0.68 [0.56-0.79]) and very good (0.92 [0.86-0.98]).
conclusionsMR-arthrography with iodinated contrast agent only displays high sensitivity and specificity for ligamentous injuries, making this technique an interesting option for exploring wrist pain.
