Aquilion 64 , CT scanner features a unique detector system that provides super-thin slices for crystal clear, comprehensive images. The scanner is engineered to generate the same high resolution in all three dimensions, allowing for multi-planar views of internal anatomical structures. In a single breath-hold of 6-10 seconds.The aim of this study was the assessment of intracranial physiological and pathological calcifications as well as intracranial space occupying lesions which are generally used to identify any lesion, whether vascular or neoplastic or inflammatory in origin which increases the volume of intracranial contents and leads to a rise in the intracranial pressure. It's often difficult for children, or people with severe breathing problems, to hold their breath and remain still for the longer times needed by older scanners, while Aquilion's ability to conduct fast, highly detailed brain scans can help stop a stroke in its tracks.
