Evaluating the role and diagnostic performance of ultrasound in diagnosing soft tissue tumors and pseudotumors in adults: a systematic review and meta-analysis.

Abstract

This systematic review and meta-analysis evaluates the combined accuracy of ultrasonic imaging in diagnosing soft tissue tumors and pseudotumors and identifies factors contributing to variability in its diagnostic accuracy. A literature search in significant databases used specific keywords and inclusion/exclusion criteria. Two authors independently performed cohort characterization and data analysis, with a third author resolving disagreements. A multivariate random effects model estimated pooled sensitivity, specificity, predictive values, and overall accuracy. Ultrasound imaging demonstrated high pooled sensitivity and specificity, indicating effectiveness in identifying lesions. Variability in accuracy was attributed to factors such as tumor type and location, operator experience, and clinic location. Ultrasonic imaging is a reliable diagnostic tool for soft tissue tumors and pseudotumors, providing high sensitivity and specificity. However, variability in accuracy underscores the need to consider operator experience and tumor characteristics. Further research should explore the impact of technological advancements and include non-English studies to enhance understanding of ultrasound imaging's diagnostic validity.
