Clinical applications of virtual, non-contrast head images derived from dual-source, dual-energy cerebrovascular computed tomography angiography
Background: This study set out to evaluate the utility of cerebrovascular virtual non-contrast (VNC) scans. Materials and Methods: Conventional non-contrast (CNC) and dual-energy computed tomography angiography (DE-CTA) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...
متن کاملDual source computed tomography coronary angiography in new onset cardiomyopathy.
AIM To evaluate safety and utility of coronary computed tomography angiography (CCTA) compared to invasive coronary angiography (ICA) in new cardiomyopathy. METHODS Eighteen patients (mean age 56.5 years, 10 males) who presented for evaluation of new onset heart failure with evidence of systolic dysfunction (ejection fraction < 40%) on echocardiography and recent ICA were prospectively enroll...
متن کاملIncidental Findings in Patients Evaluated for Pulmonary Embolism Using Computed Tomography Angiography
Introduction: Pulmonary embolism (PE) is a common lethal disease that its clinical symptoms may be seen in many other diseases. Computed tomography pulmonary angiography (CTPA) is a valuable diagnostic modality for detection of PE. In addition, it can accurately detect the other diseases with clinical symptoms similar to PE. The aim of this study is to evaluate the frequency of PE and nonemboli...
متن کاملPulmonary venous anatomy imaging with low-dose, prospectively ECG-triggered, high-pitch 128-slice dual-source computed tomography.
BACKGROUND The efforts to reduce radiation from cardiac computed tomography (CT) are essential. Using a prospectively triggered, high-pitch dual-source CT protocol, we aim to determine the radiation dose and image quality in patients undergoing pulmonary vein (PV) imaging. METHODS AND RESULTS In 94 patients (61±9 years; 71% male) who underwent 128-slice dual-source CT (pitch 3.4), radiation d...
