Initial trials of hepatic imaging using I-123-IMP

Hepatic single photon emission computed tomography (SPECT) using I-123-IMP were performed in 8 space occupying lesions of the liver. All of metastatic lesions and hemangiomas showed cold spots. Although the degree of I-123-IMP uptake were various in hepatoma, the area of tumor which corresponded closely to the enhanced parts on X ray CE-CT showed to be hot. However, the necrotic area of hepatoma were observed to be cold. Hepatic SPECT using I-123-IMP may be useful to evaluate the viability of hepatoma. (author)
