Abstract
The technological evolution of Computed Tomography in the last decade, with the development of multidetector CT scanners (MDTC), has produced innovative acquisition and study techniques; one of the most effective is undoubtedly CT Angiography (AngioCT).
AngioCT can be defined as the acquisition of a body region during the arterial phase; therefore, the scan must be performed at the peak of vascular enhancement, which means when the maximum concentration of contrast medium is present in the arteries being studied. For optimal study, an adequate venous access is necessary for the rapid bolus injection of contrast medium, with a flow rate of 3-5 ml/sec, using modern automatic injectors, followed by a bolus of saline solution, which helps to keep the contrast bolus compact for a longer time, reducing the total volumes.
The purpose of this work is not to propose an alternative study technique for CT angiography of intracranial arteries, but to provide elements aimed at optimizing this examination, particularly regarding iodinated contrast media, where optimization refers to the adoption of strategies necessary to achieve the maximum yield from the diagnostic technique in question with minimal detriment to the patient.
