Objective(s): The partial volume effect (PVE) of single-photon emission computed tomography (SPECT) on corpus striatum imaging is caused by the underestimation of specific binding ratio (SBR). A large ROI (region of interest) set using the Southampton method is independent of PVE for SBR. The present study aimed to determine the optimal ROI size with contrast and SBR for striatum images and val...
Fig. 1. Image processing steps for visceral fat partial-volume effect analysis. (a): Original WS b-SSFP abdominal fat image; (b): Automated regional segmentation on intensity-corrected image; (c): Visceral fat only image; (d): Visceral fat histogram (red curve) and the corresponding fitting curve (blue curve) for fulland partial-volume fat voxel number quantification. Visceral Fat Quantificatio...
