BACKGROUND AND PURPOSE Chemonucleolysis represents a minimally invasive percutaneous technique characterized by an intradiskal injection of materials under fluoroscopic or CT guidance. Recently, a substance based on radiopaque gelified ethanol has been introduced. The purpose of this study was to describe the indications, procedure, safety, and efficacy of radiopaque gelified ethanol in the per...

INTRODUCTION Foreign body aspiration is a significant cause of morbidity and mortality in elderly hospitalized patients. These are typically small items that patients have access to, including small coins. CASE PRESENTATION This is a case report of a 75-year-old man recently bedridden from a large hemispheric stroke with sudden onset of hoarseness, cough and dysphagia. A chest X-ray was obtai...

Currently commercially available acrylic bone cements lack adequate radiopacity and viscosity when they are used in percutaneous vertebroplasty (PVP). In this work improved formulations of radiopaque and injectable poly(methyl methacrylate) bone cements were prepared with different amounts (10-50 wt.%) of BaTiO3 or SrTiO3 particles as the radiopaque agent. Two sets of cements were prepared by u...

BACKGROUND AND OBJECTIVES Hem-o-lok clips are safe and reliable for controlling the renal vasculature. We retrospectively evaluated the CT appearance of Hem-o-lok clips in patients who had undergone laparoscopic radical nephrectomy (LRN) or nephroureterectomy (LRU) as well as their appearance on ex vivo CT scans. METHODS Between January 2006 and December 2006, 19 patients underwent LRN or LR...

There are previous reports of the identification of radiopaque medications on abdominal X-rays or computed tomography (CT). We describe an interesting case of the incidental identification of a radiopaque medication on cervical spinal CT following cervical spinal surgery. A sixty seven-year-old male patient with Parkinson's disease (PD) visited our emergency center with a C5-6 dislocation and f...

PURPOSE This prospective study was performed to achieve visualization of the reestablishment of anatomy after reconstructive surgery in the different pelvic compartments with non-absorbable radiopaque meshes, providing valuable anatomic information for surgeons implanting meshes. MATERIALS AND METHODS A total of 30 female patients with stress urinary incontinence (SUI), anterior and posterior...
