Figure 2b: Images in 55-year-old man with large biopsy-proved inoperable HCC in right lobe of liver. There was an approximately 85% reduction in tumor size with necrosis and fibrosis after one dose of 188Re HDD iodized oil. The serum AFP level also decreased to 249 from 55 582 ng/mL. At the time of this writing, the patient was alive and fully ambulatory. (a) Transverse CT scan shows large mass in right lobe of liver. (b) Angiogram in same patient. (c) Posttreatment 188Re whole-body scan shows good radiotracer accumulation in tumor, with faint visualization of lungs and liver. (d) Transverse CT scan obtained 6 months after treatment shows approximately 85% reduction in tumor size with necrosis and fibrosis. Also seen is iodized oil in the shrunken lesion.
