“…We therefore used 3DSRT, an analytic programme that can automatically establish a region of interest (ROI) after SPECT images are anatomically standardized, thus being able to quantitate rCBF despite anatomic variation. 13 Comparisons thus can be made between different subjects, and even between images obtained at different facilities.…”

“…11,12 Additionally, some investigators have reported SPECT to be useful in determining the stage of dementia 8 and in following up patients with VaD. 13 Although clinical manifestations of dementia have been extensively characterized, previous CBF SPECT studies typically have considered disease groups rather than individual patients, and have involved relatively few comparisons between disease groups. We therefore believe that the clinical value of CBF SPECT imaging in dementia warrants more detailed investigation.…”

“…An advanced fusion strategy (not limited to a color channel combination) allows the physicist to select image features to be displayed, to avoid spatial covering or frequency mixing that would hinder a good perception of the diagnostic information (e.g. hypoperfused gray matter for patients suffering from probable Alzheimer's disease (Colin & Boire, 1999)). …”

“…Multimodality image fusion has been studied in other fields, with applications varying from multifocal [6] to geographical images [7]. In medicine, image fusion has been used for brain imaging [8], [9], MRI-SPECT fusion [10], epilepsy treatment planning [11], liver ablation [12], and digital subtraction angiography [13]. For the spine, registered and overlaid CT and MR spine images have been used for surgery planning [1], [14] and evaluation of bone implants [2].…”

This study investigates a novel CT/MR spine image fusion algorithm based on graph cuts. This algorithm allows physicians to visually assess corresponding soft tissue and bony detail on a single image eliminating mental alignment and correlation needed when both CT and MR images are required for diagnosis. We state the problem as a discrete multilabel optimization of an energy functional that balances the contributions of three competing terms: (1) a squared error, which encourages the solution to be similar to the MR input, with a preference to strong MR edges; (2) a squared error, which encourages the solution to be similar to the CT input, with a preference to strong CT edges; and (3) a prior, which favors smooth solutions by encouraging neighboring pixels to have similar fused-image values. We further introduce a transparency-labeling formulation, which significantly reduces the computational load. The proposed graph-cut fusion guarantees nearly global solutions, while avoiding the pix elation artifacts that affect standard wavelet-based methods. We report several quantitative evaluations/comparisons over 40 pairs of CT/MR images acquired from 20 patients, which demonstrate a very competitive performance in comparisons to the existing methods. We further discuss various case studies, and give a representative sample of the results.
