Optimizing the diagnosis of idiopathic granulomatous mastitis with shear wave elastography: insights from Young's modulus.

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
purposeIdiopathic granulomatous mastitis (IGM) is a granulomatous condition with non-specific manifestations and a challenging diagnosis. This study aims to describe the appearance of biopsy-proven IGM lesions utilizing shear wave elastography (SWE) Young's modulus.
methodsWe performed a retrospective search for pretreatment ultrasounds of IGM referred to two tertiary breast clinics over five years. Patients with at least one pre-treatment ultrasound and pathologically-proven IGM entered the study. Ultrasound and SWE were performed and interpreted by a breast imaging fellowship-trained radiologist. The data were analyzed using SPSS software.
resultsAmong 201 pretreatment ultrasound, non-mass lesions (76%) and intercommunicating channels (52%) were the most common findings. All the patients had BIRADS of 4. The BIRADS of 4a was the most common (75%). Among 138 SWE, dark blue was the most common color in the center and periphery, with 80% and 76%, respectively. The mean stiffness (kPa) of the center was significantly higher than that of the peripheral parts in IGM lesions (P < 0.001). None of the IGM lesions were hard enough to prevent sound waves from effective propagation.
conclusionAlthough IGM mostly presents in non-specific grayscale ultrasound patterns, SWE findings can provide more specificity to imaging findings and probably can help to reach an accurate diagnosis.
