OBJECTIVE The purpose of this investigation was to characterize the MRI appearance of the quadriceps fat pad and to correlate the findings with other knee abnormalities, anatomic measurements of the extensor mechanism, and findings from history and at physical examination. MATERIALS AND METHODS Ninety-two consecutive knee MRI examinations from 84 patients(More)
The rotator interval and the long head of the biceps brachii tendon are anatomically closely associated structures believed to confer stability to the shoulder joint. Abnormalities of the rotator interval may be acquired or congenital and are associated with instability of the long head of the biceps brachii tendon. Clinical and arthroscopic diagnoses of(More)
OBJECTIVE The purpose of this study was to describe the sonographic appearance of pathologically proven isolated fat necrosis involving the extremities or torso with magnetic resonance imaging (MRI) correlation. METHODS A query of the Department of Pathology database at our institution for the diagnosis of fat necrosis resulted in 1539 cases. Review of(More)
Bisphosphonate-related osteonecrosis of the jaw (ONJ) is characterized by nonhealing exposed bone in the maxillofacial region in patients who have undergone bisphosphonate treatment. The underlying etiology is unclear and may be multifactorial. The diagnosis is primarily clinical. Diagnostic tissue sampling may exacerbate the process and is typically(More)
Traumatized teeth present a clinical challenge with regard to their diagnosis, treatment plan, and prognosis. Recent developments in imaging systems have enabled clinicians to visualize structural changes effectively. Computed tomography, magnetic resonance imaging and cone beam computed tomography are among the most commonly used systems for dental and(More)
OBJECTIVE The purpose of this study was to examine the range and prevalence of asymp tomatic findings at sonography of the shoulder. MATERIALS AND METHODS The study sample comprised 51 consecutively enrolled subjects who had no symptoms in either shoulder. Ultrasound of one shoulder per patient was performed by a musculoskeletal sonographer according to a(More)
The rotator cuff muscles generate torque forces to move the humerus while acting in concord to produce balanced compressive forces to stabilize the glenohumeral joint. Thus, rotator cuff tears are often associated with loss of shoulder strength and stability, which are crucial for optimal shoulder function. The dimensions and extent of rotator cuff tears,(More)
OBJECTIVE The purpose of this series was to retrospectively characterize the sonographic appearance of posttraumatic Morel-Lavallée lesions. METHODS After Institutional Review Board approval was obtained, a search of the radiology information system database with correlation to medical records identified 21 posttraumatic fluid collections of the hip and(More)
OBJECTIVE The purpose of this article is to describe the anatomy of the inguinal region in a way that is useful for sonographic diagnosis of inguinal region hernias, and to illustrate the sonographic appearance of this anatomy. We show sonographic techniques for evaluating inguinal, femoral, and spigelian hernias and include surgically proven examples. (More)
PURPOSE To characterize the ultrasonographic (US) appearance of the rotator cuff cable in asymptomatic shoulders and in cadaveric specimens, with histologic comparison for the latter. MATERIALS AND METHODS The cadaveric portion of this study was approved by the institution's Anatomical Donations Department. Institutional review board approval and informed(More)
