Apart from, lacking sufficient sensitivity and specificity, these techniques pose a challenge when defining the anatomic extent of disease, in case of planning highly conformal radiation treatment or highly targeted therapeutic regimens (Zaidi et al., 2008; Vogel et al., 2004). Functional imaging with 18-fluorodeoxyglucose, (18F-FDG) PET, despite a high detection sensitivity reaching below the picomolar range, produces a relatively low spatial resolution of images (range: 4–6 mm and physically limited to about 2 mm) along with poor recognition capacity and delineation of anatomic structures, which may lead to uncertainty or failure in correctly localizing detected abnormalities. A few examples include lesions in the upper abdomen, situated near the border of organs, or between adjacent organs (Vogel et al., 2004). In order to address these shortcomings of stand-alone CT and PET imaging modalities, whilst taking advantage of the less redundant and highly complimentary information from different imaging techniques, the present technology explores software- and/ or hardware-based correlative functional-anatomic imaging combining PET with CT or MR imaging modalities (PET/CT and PET/MRI) (Judenhofer et al., 2008). In view of the above and the emerging data, the present paper discusses software and hardware fusion with respect to the two dual-modality imaging technologies (PET/CT and PET/MRI), their role in a clinical setting, possibilities, limitations and technological obstacles. Software-based image registration and fusion with respect to PET/CT and PET/MRI Software-based image registration and fusion techniques basically involve the integration of two or more image sets from two or more different imaging modalities following their separate acquisition on stand-alone imaging systems. When a colorful image of functional feature is superimposed over a gray-scale CT or MR image of the corresponding anatomic region the resulting fused image has a small rotation along 3D axes and displacement, which could be corrected manually (Vogel et al., 2004, Zaidi et al., 2008). A study by Vogel et al. (2004), focusing on PET/CT commented that although numerous algorithms including, count difference, shape difference, mutual information, normalized mutual information, have been developed, the resultant fused images, vary in accuracy (p. 18S). Software-based image registration techniques employ two approaches namely, rigid and non-rigid registration of images. Research by Slomka & Baum (2009) highlights the accuracy of rigid image registration of brain PET with CT and MRI in case of software techniques. Non-rigid registration approaches are usually combined with linear registration tech ...Download file to see next pagesRead More
