Fig. 1 Images of 64-year-old man with diagnosed squamous cell carcinoma of the left upper lung. The extent of primary tumor in the left hilum (arrow) was not accurately distinguished from the secondary changes on axial MDCT (a). Tumor (arrow) was appeared as slightly hypointense compared the signal of secondary changes on axial T2-weighted MRI (b). Tumor (arrow) was showed as hypointense while that of secondary changes were hyperintense in early phase of dynamic contrast-enhanced MRI (c and d), in delay phase both of them were appeared as heterogeneously hyperintanse (e and f)

Upper row: The SPM of the t statistics is displayed in a standard format as a maximum intensity projection viewed from the right hand side (left image), the back (middle image), and the top (right image) of the brain. The anatomic space corresponds to the atlas of Talairach and Tournoux. Lower row: Significance maps of decreased gray matter volume in AD patients superimposed on a T1-weighted brain MRI template image in Montreal Neurological Institute (MNI) space.

Figure 1 Procedure of tensor-based morphometry using brain SPECT. First, an original SPECT image (A) is linearly transformed to the Talairach space. Subsequent non-linear spatial normalization using the high-dimension-warping algorithm deforms a linearly standardized brain (B) to match it to a 99mTc-ECD template (C). This step generates a high-dimensionally warped SPECT image (D) and a parametric image of Jacobian determinants (E) indicating a local volume change relative to the template brain. Then the natural logarithm of this parametric image (F) is separated into negative log J (G) and positive log J maps (H) representing contraction and expansion respectively. A conventionally warped SPECT image is also shown (I).
