The great advantage of the ultrasonographic study, which has motivated enthusiastic research in the area, resides in its… (More)
OBJECTIVE The aim of our study was to systematically compare different methodologies to establish an evidence-based approach based on tendon thickness and structure for sonographic diagnosis of supraspinatus tendinopathy when compared to MRI. METHODS US was obtained from 164 symptomatic patients with supraspinatus tendinopathy detected at MRI and 42… (More)
Injury to the ulnar collateral ligament (UCL) complex of the thumb is a common traumatic lesion that requires prompt imaging evaluation for adequate treatment. In this article, we review the role of ultrasound in diagnosis and illustrate the spectrum of both static and dynamic findings related to the UCL injuries. We also describe a number of alternative… (More)
OBJECTIVE The purpose of this study was to determine whether exclusively long-axis sonography differs from a multiple-axis scanning protocol as a screening tool for rotator cuff lesions in symptomatic shoulders when compared with magnetic resonance imaging (MRI). METHODS A total of 509 consecutive patients (mean age, 52.8 years) referred for MRI were also… (More)
The acromial origin of the deltoid is a target structure of ankylosing spondylitis and related spondyloarthritis, which are often overlooked and underdiagnosed as causes of posterior shoulder pain. The objective of this article is to review the roles of sonography and magnetic resonance imaging in detecting deltoideal acromial enthesopathy and their… (More)
The purpose of this article is to stimulate the use of the vernacular by health professionals, commenting a few words usually employed in communication between rheumatologists.
Sonography is a fast, painless, inexpensive, and widely available tool usually regarded as a first-line imaging modality for abdominal wall evaluation. This article provides illustrative images and videos on the use of sonography for diagnosis of abdominal wall hernias. A variety of pitfalls that may present clinically as pseudohernias are also described.
