Following image acquisition, there are several steps to processing the image data in order to achieve the final analysis. These steps may include coregistration of SPECT and PET images with CT or MRI images, attenuation correction, drawing of regions of interest (ROIs), generation of time-activity curves (TACs), and normalization of TACs for injected dose and body weight. The Johns Hopkins SAIRP provides a service center to perform all analysis procedures. The purpose of the center is to teach investigators the concepts behind the analytical methods, and to train users to perform their own analyses. We also provide dedicated computers for data analysis that feature the commercial medical imaging software Analyze, in addition to common shareware utilities such as Amide, ImageJ, and MIPAV. To arrange a meeting to review analysis procedures or to reserve time on the analysis computer, contact Chris Endres.
