Overuse and underuse of pulmonary CT angiography in patients with suspected pulmonary embolism
Background: The aim of the present study was to evaluate the utilization and diagnostic yields of CT pulmonary angiography (CTPA) using the Revised Geneva score and Wells’ criteria, in patients with suspected pulmonary embolism (PE). Methods: One hundred and twelve adult patients underwent CTPA for suspected PE were participated in this study. The outcome was positive or neg...
متن کاملAssessment of pulmonary arterial enhancement on CT pulmonary angiography using a leg vein for contrast media administration
The purpose of our study was to compare pulmonary artery (PA) enhancement according to venous routes of contrast media (CM) administration in patients who underwent CT pulmonary angiography (CTPA) in the emergency department (ED).This retrospective study reviewed the CTPAs of 24 patients who administered CM via leg veins (group A) and 72 patients via arm veins (group B) with age and gender matc...
متن کامل4D-CT Simulation using Individually Optimized Contrast Enhancement (CE): A Phantom Study
Innovation/Impact: 4D-CT simulation has been widely used to estimate the respiratory motion of lung tumors and abdominal tumors for radiotherapy planning. However, most abdominal tumors (liver, pancreas etc.) cannot be readily visualized in CT without dynamic CE. It is desirable to combine a 4D-CT without CE and a CE 3D-CT into a CE 4D-CT so that we can both visualize the tumor and estimate its...
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...
متن کاملAutomatic multiscale enhancement and segmentation of pulmonary vessels in CT pulmonary angiography images for CAD applications.
The authors are developing a computerized pulmonary vessel segmentation method for a computer-aided pulmonary embolism (PE) detection system on computed tomographic pulmonary angiography (CTPA) images. Because PE only occurs inside pulmonary arteries, an automatic and accurate segmentation of the pulmonary vessels in 3D CTPA images is an essential step for the PE CAD system. To segment the pulm...
