Spontaneous massive hemothorax presenting as a late complication of stent implantation in a patient with pulmonary vein stenosis following radiofrequency ablation for atrial fibrillation.

Catheter ablation for symptomatic and drug-resistant atrial fibrillation is considered as the main acquired cause of pulmonary vein stenosis in adults. Controversy currently exists about the optimal treatment approach of this entity. Stenting seems to achieve lower vessel restenosis rates than isolated balloon angioplasty.

Integrating CAD modules in a PACS environment using a wide computing infrastructure.

Purpose: The aim of this paper is to describe a project designed to achieve a total integration of different CAD algorithms into the PACS environment by using a wide computing infrastructure.

Methods: The aim is to build a system for the entire region of Galicia, Spain, to make CAD accessible to multiple hospitals by employing different PACSs and clinical workstations. The new CAD model seeks to connect different devices (CAD systems, acquisition modalities, workstations and PACS) by means of networking based on a platform that will offer different CAD services.

Breast hemangiomas: correlation between imaging and pathologic findings.

Hemangiomas are benign vascular tumors that are rare in the breast. A high percentage of hemangiomas are diagnosed incidentally during imaging examinations. They have mammographic, sonographic, and pathologic characteristics that allow radiologists and pathologists to diagnose them.
