Cone-beam CT for breast imaging: Radiation dose, breast coverage, and image quality.

Objective: The primary objectives of this pilot study were to evaluate the radiation dose, breast coverage, and image quality of cone-beam breast CT compared with a conventional mammographic examination. Image quality analysis was focused on the concordance of cone-beam breast CT with conventional mammography in terms of mammographic findings.

Subjects And Methods: This prospective study was performed from July 2006 through August 2008.

Dual-tract transhepatic U-shaped hemodialysis inferior vena cava catheter: a feasibility study in a swine model.

Purpose: To evaluate the feasibility of establishing a U-shaped inferior vena cava (IVC) catheter entirely from a transhepatic approach and to determine the catheter caliber that would provide adequate flow for hemodialysis.

Materials And Methods: Three pigs (weight, 45-50 kg) were used. A peripheral right hepatic vein was accessed transhepatically by using a 22-gauge needle, and a 0.

Post-lymphangiographic computed tomography in chylothorax after esophagogastrectomy: a case report.

Chylothorax is a rare complication of thoracic surgery. Lymphangiography has long been considered to be the standard of reference for diagnosis and post-treatment evaluation while the role of post-lymangiographic CT is debated. We report a case of chylothorax in a 68-year-old male following esophagogastrectomy for which conservative treatment and thoracic duct ligation failed.

Comparison of vasa vasorum after intravascular stent placement with sirolimis drug-eluting and bare metal stents.

The cytostatic drug, sirolimis has shown prevention in neointimal hyperplasia after stent placement. Recent studies have shown persistent inflammation seen with drug-eluting stents (DES) may result in late stent thrombosis. The aim of this study is to compare effects of bare metal stents (BMS) and sirolimis DES on the neointima and vasa vasorum in stented rabbit aortas.
