Peripheral Venous Ultrasound.

After clinical evaluation, especially clinical prediction rules, appropriately ordered venous duplex has become the standard test for evaluating and excluding deep vein thrombosis (DVT). Ultrasound is useful for lower- and upper-extremity veins. Protocols include grayscale, color Doppler, and spectral Doppler.

Peripheral Arterial Ultrasound.

Peripheral arterial ultrasound is an important technique to evaluate vascular disease. Protocols include grayscale, color Doppler and spectral Doppler. Arterial duplex is used to evaluate patients with claudication to characterize atherosclerotic disease.

Spinal ganglion cyst presenting with radiculopathy: diagnostic challenges and differential.

Introduction: Ganglion cysts are benign soft tissue lesions, usually arising from periarticular connective tissue. These are very rarely reported in the spine, but when seen can cause radiculopathy or myelopathy.

Case Presentation: A 68-year-old female patient presented with worsening radiculopathy and right foot drop and imaging noted a right L5-S1 foraminal mass.

Sensitization, pathologic, and imaging findings comparing symptomatic and quiescent failed renal allografts.

Late allograft failure (LAF) is a common cause of end stage renal disease. These patients face interrelated challenges regarding immunosuppression management, risk of graft intolerance syndrome (GIS), and sensitization. This retrospective study analyzes sensitization, pathology, imaging, and transfusion requirements in 33 LAFs presenting either with GIS (22) or grafts remaining quiescent (11).

Adnexal torsion: new clinical and imaging observations by sonography, computed tomography, and magnetic resonance imaging.

Objective: The purpose of this study was to review the clinical, imaging, and pathologic findings associated with adnexal torsion.

Methods: A review of surgically proven cases of torsion between 1990 and 2006 included clinical, surgical, and pathologic data and preoperative sonographic, computed tomographic (CT), and magnetic resonance imaging (MRI) studies. Imaging reports were assessed to determine whether a correct preoperative diagnosis was made.

Lateral epicondylitis of the elbow: US findings.

Purpose: To determine the sensitivity and specificity of ultrasonography (US) in the detection of lateral epicondylitis and identify the US findings that are most strongly associated with symptoms.

Materials And Methods: Internal review board approval was obtained for retrospective review of the patient images, and the need for informed consent was waived. Internal review board approval was also obtained for scanning the 10 volunteers, all of whom gave informed consent.

Ultrasound-guided biopsies: tricks, needle tips, and other fine points.

Ultrasound (US)-guided biopsy of thyroid nodules, abdominal masses, liver masses, random core liver biopsies, as well as aspiration of abdominal or pleural fluid is now routine practice. The ability of US to guide biopsy of abnormalities seen on cross-sectional imaging studies is well recognized as an efficient and effective means of achieving a tissue diagnosis. Its use requires basic knowledge of US image analysis, but clinically useful intuitive and nonintuitive methods can enhance its strengths.

Retroperitoneal laparoscopic cryoablation of small renal tumors: intermediate results.

Objectives: To present our experience with laparoscopic renal cryoablation with up to 3 years of follow-up. Laparoscopic renal cryoablation remains a viable option for the treatment of small peripheral renal masses in patients with significant comorbidities. Although partial nephrectomy has been shown to be a safe and reliable method of renal parenchymal preservation, laparoscopic cryoablation still requires longer term data to prove its efficacy.
