OBJECTIVE The aim of this study was to investigate the image quality, radiation dose, and accuracy of virtual noncontrast images and iodine quantification of split-filter dual-energy computed tomography (CT) using a single x-ray source in a phantom and patient study. MATERIALS AND METHODS In a phantom study, objective image quality and accuracy of iodine(More)
Extraskeletal Ewing's sarcoma (EES) is a rare soft tissue tumor that is morphologically indistinguishable from skeletal ES. We report a case of a 25-year-old female with recurrent EES/primitive neuroectodermal tumor of right breast with imaging findings on mammogram, ultrasound, magnetic resonance imaging breast, and positron emission tomography-computed(More)
INTRODUCTION Urolithiasis is one of the major, recurring problem in young individuals and CT being the commonest diagnostic modality used. In order to reduce the radiation dose to the patient who are young and as stone formation is a recurring process; one of the simplest way would be, low dose CT along with tube current modulation. AIM Aim of this study(More)
Rising concerns of radiation exposure from computed tomography have caused various advances in dose reduction technologies. While proper justification and optimization of scans has been the main focus to address increasing doses, the value of dose management has been largely overlooked. The purpose of this article is to explain the importance of dose(More)
OBJECTIVE The purpose of this study is to compare diagnostic reference levels from a local European CT dose registry, using radiation-tracking software from a large patient sample, with preexisting European and North American diagnostic reference levels. MATERIALS AND METHODS Data (n = 43,761 CT scans obtained over the course of 2 years) for the European(More)
We report the eighth case of eosinophilic mastitis and the first one without an association with peripheral eosinophilia or systemic involvement. A 51-year-old diabetic presented with a painful right breast lump. The mammogram, ultrasound, and magnetic resonance imaging suggested a diagnosis of periductal mastitis, however, a sinister etiology of breast(More)
PURPOSE To determine the diagnostic potential of Material Density (MD) iodine images in dual-energy CT (DECT) for the detection and characterization of hypervascular liver lesions compared to monenergetic 65keV images, using MRI as the standard. MATERIALS AND METHODS The study complied with HIPAA guidelines and was approved by the institutional review(More)
