background and objective:determination of her2 gene is crucial in breast carcinoma management and prognosis, as her2 alterations are linked to a shorter disease-free period, overall survival and resistance to tamoxifen anti-estrogen therapy and other chemotherapy regimens, regardless of the nodal or hormone receptor status. this study aimed to estimate her2 gene status of infiltrative mammary c...

PURPOSE Three-dimensional (3D) reformatted images provide a more inclusive representation of abnormalities than transverse images in cranial computed tomography (CT). The purpose of this study was to assess the value of 3D reformations for radiology residents in the interpretation of emergency cranial CTs. MATERIALS AND METHODS In total, 218 consecutive patients who underwent emergency crania...

patients and methods in 382 subjects admitted in the emergency department (ed), we evaluated maximal (volmax) and minimal (volmin) la volumes and la emptying fraction (la-ef), from rt-3d images, with a semiautomated border detection program. a follow-up was performed in order to evaluate all-cause mortality and new hospital admission for cardiovascular events. objectives aims of this study were...

Volumetric data is common in medicine, geology and engineering, but the O(n) complexity in data and algorithms has prevented the widespread use of volume graphics. Recently, 3D image processing and visualization algorithms have been parallelized and ported to graphics processing units. Today, medical diagnostics highly depends on volumetric imaging methods that must be visualized in real-time. ...

INTRODUCTION: Pre-pectoral direct to implant (DTI) breast reconstruction has historically been fraught with complications including flap necrosis, implant extrusion, and capsular contracture as well as extremely high rates of operative revisions. This may result from a number of factors, including the lack of an algorithmic approach, failure to predict postoperative migration of the implant, us...

PURPOSE The use of SPECT/CT in bone scans has been widespread in recent years, but there are no specific guidelines concerning the optimal acquisition protocol. Two strategies have been proposed: targeted SPECT/CT for equivocal lesions detected on planar images or systematic whole-body SPECT/CT. Our aim was to compare the diagnostic accuracy of the two approaches. METHODS 212 consecutive pati...

Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...

BACKGROUND AND PURPOSE Classification of variations of the superficial middle cerebral vein (SMCV) remains ambiguous. We propose a new classification system based on embryologic development for preoperative examination. METHODS Three-dimensional CT angiography was used to evaluate 500 SMCVs (in 250 patients). The outflow vessels from the SMCV were classified into seven types on the basis of e...
