Gamma camera and SPECT imaging after infusion of131I-huA33. Whole body gamma camera image (a) anterior and (b) posterior of patient 6 at 6 days following infusion of 131I-huA33. Excellent uptake of 131I-huA33 in extensive liver metastases involving the entire right lobe of liver (arrow) is evident, with some bowel uptake (double arrows) also seen. Coronal SPECT (c) and transverse SPECT (d) through the right lobe of liver showing 131I-huA33 uptake in metastatic disease throughout the right lobe of liver, with some central reduced uptake due to necrosis (confirmed on histology of resected hepatic lobe).
