PURPOSE To evaluate the feasibility of use and safety of a targeted radiofrequency ablation (RFA) device for metastatic posterior vertebral body tumors. MATERIALS AND METHODS This retrospective study was institutional review board approved and HIPAA compliant. Consent was waived for retrospective participation. Fluoroscopic or computed tomography-guided(More)
BACKGROUND Spinal metastatic lesions are a common occurrence among oncology patients and contribute to significant morbidity. Treatment options have been limited in their effectiveness and scope to this point. OBJECTIVE This study aims to report the safety and efficacy of radiofrequency ablation (RFA) of malignant spinal lesions using a novel RFA bipolar(More)
Carcinoid tumors are primary malignant neoplasms that arise from neuroendocrine cells. These cells are located throughout the body, resulting in many possible locations for the development of carcinoid tumor. The most common primary location is the gastrointestinal tract, followed by respiratory and thymic carcinoids. The presentations of these tumors are(More)
OBJECTIVES To develop comprehensive and reliable radiation-free methods to quantify femoral and acetabular morphology using MRI. METHODS 32 hips (16 subjects, 6 with intra-articular hip disorder (IAHD); 10 controls) were included. A 1.5T magnetic resonance system was used to obtain 3D fat suppressed gradient echo images at the pelvis and distal femora.(More)
BACKGROUND Radiation therapy (RT) is the current gold standard for palliation of painful vertebral metastases. However, other percutaneous modalities such as radiofrequency ablation (RFA), cryoablation, and vertebral augmentation have also been shown to be effective in alleviating symptoms. Combined RT and ablation may be more effective than either therapy(More)
BACKGROUND Previous studies have found a relationship between single indicators of ventilatory capacity and measures of cognitive function, but have not addressed dementia specifically. This study examined the relationship between different indicators of ventilatory capacity and dementia, diagnosed according to the Diagnostic and Statistical Manual of(More)
OBJECTIVES Studies on extracranial carotid atherosclerosis have predominately been undertaken on middle-aged subjects. This study examines the prevalence of extracranial carotid atherosclerosis, its relation to vascular risk factors and its significance for survival in elderly subjects. DESIGN Population-based cross-sectional survey. Non-modifiable(More)
This article reviews the basics of image-guided intervention of musculoskeletal neoplasms. Image-guided procedures are playing an ever-increasing role in the diagnosis, staging, and treatment of musculoskeletal tumors. The successful handling of these lesions necessitates a multidisciplinary approach, with the radiologist working closely with the orthopedic(More)
PURPOSE To describe a new complication and retrospectively identify the incidence and risk factors for hip chondrolysis and femoral head osteonecrosis associated with percutaneous cryoablation of periacetabular malignancies. MATERIALS AND METHODS In this retrospective study, 45 patients with a total of 113 musculoskeletal lesions were treated by(More)
BACKGROUND AND PURPOSE Percutaneous cryoablation has emerged as a minimally invasive technique for the management of osseous metastases. The purpose of this study was to assess the safety and effectiveness of percutaneous imaging-guided spine cryoablation for pain palliation and local tumor control for vertebral metastases.
