Abstract

Abstract: Background/Purpose: The diagnosis of gallbladder (GB) lesions is occasionally difficult. Recently, superb microvascular imaging (SMI) of ultrasound has been developed as a novel microvascular imaging technique. We evaluated the feasibility of SMI for the diagnosis of GB lesions and compared microvascular imaging between benign and malignant GB lesions. Methods: Twenty patients with GB‐protruded lesions or wall thickening who underwent SMI from August 2015 to July 2017 were included in this retrospective study. The measured outcomes were the quality of microvascular imaging when compared between normal SMI (N‐SMI) and contrast‐enhanced SMI (CE‐SMI), and the microvascular findings (vascularity, vascular morphology, presence of branching, and presence of caliber change) when compared between benign and malignant GB lesions. Results: The quality of microvascular imaging of CE‐SMI was evaluated as better than that of N‐SMI, showing a significant difference ( P < .001). From the CE‐SMI microvascular findings, the evaluation of vascular morphology and the presence of caliber change showed a significant difference between benign and malignant GB lesions ( P = .005, P < .001). Conclusions: The evaluation of GB lesions using SMI was feasible with a contrast agent. Vascular morphology and the presence of caliber change may help in the differential diagnosis of GB lesions. Abstract : This retrospective study evaluated microvascular imaging of gallbladder lesions using the superb microvascular imaging ultrasound technique. Kin and colleagues showed that the evaluation of gallbladder lesions using superb microvascular imaging was feasible with a contrast agent and that the microvascular findings may help in the differential diagnosis of gallbladder lesions.
