In the treatment of cerebral ischemia, it is often said that “time is brain.” The faster the clinician can detect areas of decreased blood flow and determine the optimal treatment pathway, the better the patient’s chances for survival and recovery.

For perfusion analysis to be effective and accurate, the data needs to be taken with an imaging modality capable of acquiring temporally uniform dynamic images of the entire anatomy, have sufficient temporal sampling, and the perfusion algorithm can represent flow characteristics independent of the image acquisition and contrast injection processes.

Our CT scanners and post-processing software are capable of high resolution, three dimensional imaging, essentially eliminating the previous concerns in perfusion imaging. The partial brain coverage limitations of CT perfusion were addressed with the introduction of the Wide Area Detector on the Aquilion ONE series and the shuttle mode in Aquilion Prime. Visualization of fine detail of anatomical structures is now feasible with Aquilion Precision, the world’s first Ultra-High Resolution CT scanner.

Unique bi-directional gantry tilt, Single Energy Metal Artifact Reduction (SEMAR), Deep Learning Spectral Imaging and SURESubtraction bone removal eliminate various other challenges often experienced in Neurology imaging.

“The combination of whole brain perfusion and SEMAR means enormous diagnostic and clinical improvements providing added value in everyday clinical practice.”
