Pulsatile To-and-Fro Flow Detected by Contrast-Enhanced Electrocardiogram-Gated Computed Tomography

Images in Cardiovascular Medicine Pulsatile To-and-Fro Flow Detected by Contrast-Enhanced Electrocardiogram-Gated Computed Tomography A Novel Method for Detecting the Leakage Point of a Pseudoaneurysm

A 64-year-old man came to the emergency department complaining of dyspnea. He had a history of ascending aortic pseudoaneurysm treated by ascending aortic and total arch replacement 2 months before. Because he had had deep vein thrombosis of the femoral vein, pulmonary thromboembolism was suspected, and contrast-enhanced computed tomography (CT) of the chest was performed. The dose-length produ...

Pulsatile to-and-fro flow detected by contrast-enhanced electrocardiogram-gated computed tomography: a novel method for detecting the leakage point of a pseudoaneurysm.

Contrast Enhanced Computed Tomography

Detection of coronary artery stenoses by contrast-enhanced, retrospectively electrocardiographically-gated, multislice spiral computed tomography.

BACKGROUND Multislice spiral computed tomography (MSCT) with retrospectively ECG-gated image reconstruction permits coronary artery visualization. We investigated the method's ability to identify high-grade coronary artery stenoses and occlusions. METHODS AND RESULTS A total of 64 consecutive patients were studied by MSCT (4x1 mm cross-sections, 500-ms rotation, table feed 1.5 mm/rotation, in...

Evaluation of blunt pancreatic injury with contrast-enhanced ultrasonography in comparison with contrast-enhanced computed tomography

The aim of the present study was to evaluate acute blunt pancreatic injury using contrast-enhanced ultrasonography (CEUS) in comparison with contrast-enhanced computed tomography (CECT). Superficial and deep lesions were established by blunt pancreatic injury in 40 Chinese Guangxi Bama miniature pigs. Conventional ultrasound (US), CEUS and CECT were performed to detect traumatic lesions in the ...
