We screened the suitable image reconstruction to observe the abdominal artery and compare the quality between the polychromatic and the monochromatic reconstruction images of the abdominal artery spectrum CT. Eighty patients underwent Gemstone CT energy spectrum imaging to obtain an abdominal artery polychromatic image (140 kVp) and a monochromatic image from 40 ~ 140 keV. The CT value of region of interest (ROI) was measured on the polychromatic image and the single energy image. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the abdominal aorta and hepatic artery were determined...

The aim of this study was to evaluate whether diagnosing pulmonary fibrosis with projection radiography can be improved by using X-ray dark-field radiograms. Pulmonary X-ray transmission and dark-field images of C57Bl/6N mice, either treated with bleomycin to induce pulmonary fibrosis or PBS to serve as controls, were acquired with a prototype grating-based small-animal scanner. Two blinded readers, both experienced radiologists and familiar with dark-field imaging, had to assess dark-field and transmission images for the absence or presence of fibrosis...

INTRODUCTION: Posttraumatic osteomyelitis (PTO) is a feared complication after surgical fracture care. Late diagnosis can result in interrupted and prolonged rehabilitation programmes, inability to work, medical dependency, unnecessary hospital admissions, and high medical and non-medical costs. Primary aim of this study was to assess preferred diagnostic imaging strategies for diagnosing PTO amongst orthopaedic and trauma surgeons, radiologists, and nuclear medicine physicians. Secondary aims were to determine the preferred serum inflammatory marker for diagnosing PTO and the existence of a local hospital protocol to diagnose and manage PTO...

One of the rare but most challenging issues in the management of the locally-advanced breast cancer (LABC) is life-threatening bleeding from the fungating and/or ulcerating focus (foci) of these tumors. Breast surgeons may need the assistance of interventional radiologists to solve this urgent condition if surgery cannot provide sufficient benefit. Herein, we report a case of recurrent locally-advanced breast cancer that presented with sudden severe bleeding, which was stopped by an interventional radiologist via transcatheter arterial embolization (TAE)...

BACKGROUND: Gastric leak (GL) is one of the main early-onset postoperative complications of sleeve gastrectomy (SG). Many institutions perform routine upper gastrointestinal (UGI) contrast studies within 24 hours of surgery, looking for GL or gastric stenosis and to determine the need for urgent re-exploration, but this examination delays oral feeding, can cause side effects and is responsible for systematic and probably unnecessary irradiation of the patient. OBJECTIVE: Determine the efficacy of routine UGI contrast studies to predict postoperative complications after SG in a large population...

REVIEW
A Ruggiero, N J Screaton
Acute pulmonary embolism (PE) is a life-threatening condition that requires prompt diagnosis and treatment. Recent advances in imaging allow acute and rapid recognition even by the non-specialist radiologist. Most acute emboli resolve on anticoagulation without sequelae; however, some emboli fail to fully resolve becoming endothelialised with the development of chronic thromboembolic disease (CTED). Increased pulmonary vascular resistance arising from CTED may lead to chronic thromboembolic pulmonary hypertension (CTEPH) a debilitating disease affecting up to 5% of survivors of acute PE...
