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 کاملA novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study
In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...
متن کاملAssessment of Contrast Media Volume Injected and Image Contrast in Abdominal Pelvic CT Scan and Related Factors in Referral Hospitals in Mazandaran, Iran
Background and purpose: Computed tomography scan (CT) is highly capable of diagnosing abdominal and pelvic lesions. Injection of contrast media at appropriate concentration and volume provides the least side effects and the highest image quality. This study aimed at investigating the volume of contrast medium injected and the level of image contrast compared to the standard model, in the imagi...
متن کاملA feasibility study on the use of MV-CBCT images for urgent palliative treatment planning
Introduction: The application of 3D volumetric imaging modalities in treatment planning of radiation therapy can provide more precisely define tumor localization, and computed tomography (CT) is the most common accepted method for treatment planning. Given the lack of a CT scanner stationed in all radiotherapy departments and equipping most of the medical linear accelerators wi...
متن کاملContrast Induced Nephropathy After Brain and Cervical CT Angiography in Stroke Patients: A Prospective Study
Background: Contrast-induced nephropathy (CIN) is a major side effect of intravenous iodinated contrast and causes both short- and long-term adverse effects. While diagnostic and interventional procedures of brain ischemia are recently advanced, it is necessary to be cautious about its major side effect. Objectives: To evaluate CIN and its risk factors in neurology patients after brain and cer...
