In vivo visualization of heterogeneous intratumoral distribution of POS by SPECT/CT. The comparison of in vivo SPECT images and ex vivo images. Upper raw: in vivo SPECT images, lower raw: ex vivo SPECT images, left column: sagittal sectional images, right column: axial sectional images. Arrows 1: markers for coregistration, arrows 2: vertebrae, and arrowheads: the tumor.
