FIGURE 6. (A) Axial HCT and PET data (corrected by HCT) for tumor 11 (patient 6). (B) Corresponding ACT and PET data (corrected by ACT). SUV for HCT PET and ACT PET were 1.9 and 3.8, respectively. SUV increased 97.4% from HCT PET to ACT PET. (C) Coronal HCT, HCT PET, and maximum-intensity projection (MIP) of HCT PET data. (D) Coronal ACT, ACT PET, and MIP of ACT PET data. With ACT, there was a significant reduction in breathing artifacts caused by different breathing states during HCT and PET. On each image, crosshair or arrow indicates tumor location.
