PROGRAM, RECORDING MEDIUM, AND METHOD FOR IMAGING RECEPTOR BINDING POTENTIAL

摘要

PROBLEM TO BE SOLVED: To provide a BP (Binding Potential) imaging program capable of; presenting BP of abnormal regions even if both normal and abnormal regions are present in an ROI (Region of Interest); presenting BP for a brain under pathological conditions with damage to gray matter or white matter; accurately identifying anatomical regions on a PET brain image; and facilitating BP evaluation of the whole cerebral region.

SOLUTION: A BP imaging program includes steps of; aligning an MRI brain image to a PET brain image; separating gray matter portions and white matter portions from the MRI brain image and applying noise removal processing; defining an ROI in a reference region of the MRI brain image and defining the same ROI on the PET brain image; defining an elliptical ROI on the PET brain image and inputting a time-radiation count value for each pixel therein; computing BP for each pixel in the elliptical ROI of the PET brain image by means of the reference region method using the PET brain image in the elliptical ROI and the time-radiation count values in the ROI in the reference region; and displaying BP in the gray matter portions and/or white matter portions.
