Accuracy of uncalibrated 2D digital subtraction angiography measurements on a novel biplane system compared to computed tomography angiography.

Background: 2D digital subtraction angiography (DSA) images are the gold standard for neuroradiological vascular assessment and the basis of interventional procedures such as mechanical thrombectomy and cerebral aneurysm coiling. However, length measurements in projected DSA images are affected by the distance between the x-ray source, the object, and the detector. Precise coordination between all integrated parts of a novel biplane system makes it possible to accurately measure DSA distances without manual calibration.

FDG-accumulating atherosclerotic plaques identified with 18F-FDG-PET/CT in 141 patients.

Purpose: The aim of this study was to describe the prevalence of atherosclerotic plaques based on [(18)F]-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) in a large population characterized by high risk of cardiovascular disease.

Procedures: One hundred forty-one patients referred to our department for FDG-PET/CT for suspected lung cancer were re-evaluated for atherosclerotic lesions. Cardiovascular risk factors were analyzed based on patient records.
