CONTRAST MEDIA USED IN COMPUTED TOMOGRAPHY

Contrast Media in Abdominal Computed Tomography: Optimization of Delivery Methods

OBJECTIVE To provide a systematic overview of the effects of various parameters on contrast enhancement within the same population, an animal experiment as well as a computer-aided simulation study was performed. MATERIALS AND METHODS In an animal experiment, single-level dynamic CT through the liver was performed at 5-second intervals just after the injection of contrast medium for 3 minutes...

Contrast Enhanced Computed Tomography

Application of 270 mgI/mL Iodinated Contrast Media in Dual-Source Computed Tomography Coronary Artery Imaging.

BACKGROUND This study aimed to explore the application of 270 mg I/mL iodinated contrast agent with a tube voltage of 100 kV scanning in coronary computed tomography angiography (CCTA). METHODS This CCTA study was a prospective observational study. The two radiologists were blinded to both patient information and image date arrangement. One-hundred twenty patients (body mass index < 25.0 kg/m...

Intravenous contrast media application using cone-beam computed tomography in a rabbit model

PURPOSE This study was performed to evaluate the feasibility of visualizing soft tissue lesions and vascular structures using contrast-enhanced cone-beam computed tomography (CE-CBCT) after the intravenous administration of a contrast medium in an animal model. MATERIALS AND METHODS CBCT was performed on six rabbits after a contrast medium was administered using an injection dose of 2 mL/kg b...

Immediate adverse reactions to intravenous iodinated contrast media in computed tomography.

This exploratory-descriptive, non-experimental quantitative research aimed to learn about immediate adverse reactions to intravenous iodinated contrast media in hospitalized patients submitted to computed tomography at a teaching hospital in the South of Brazil. During the study period, all adverse reactions showed mild intensity, at a frequency of 12.5% with ionic iodinated contrast media, and...
