The fact that colloidal particulates of rdaiogold are mainly and effectively eliminated from the blood stream by phagocytic activity of Kupffer's cells of the liver has been successfully adopted to the diagnosis if certain liver diseases and the same principle has opened a new avenue to the study of the organ by obtaining scan. Indeed, the latter procedure has been widely used for the detection of space-occupying lesions of cirrhosis of the liver. Nevertheless problem of differential diagnosis of monochromatic "cold" areas or "mottling" of the internal structure on the scan limited the value of this diagnostic modality. The present investigation is aimed at improving intepretation of photoscan findings with the aid of blood clearance rate of the intravenously injected colloidal $^{198}Au$.

A 67-year-old male was admitted due to abdominal pain. Abdominal CT scan performed in a local clinic showed about 2 cm sized pancreatic tail mass with extensive liver and multiple regional lymph node metastasis. Histology of liver biopsy revealed poorly differentiated adenocarcinoma. He underwent chemotherapy with gemcitabine and erlotinib for 5 cycles followed by 8 cycles of second line chemotherapy with 5-fluorouracil and cisplatin. At 12 months after diagnosis, follow-up abdominal CT scan revealed marked reduction of tumor mass in the liver and pancreas with small residual tumor. After one month of last chemotherapy, he complained radiating pain along left leg. Blood chemistry revealed isolated elevation of alkaline phosphatase (ALP) and multiple bone metastasis were demonstrated in bone scan. Palliative radiation therapy to pelvic bone was performed for the relief of bone pain. The prognosis of advanced pancreatic cancer is extremely poor. We report late occurrence of multiple bone metastasis in a patient with well controlled advanced pancreatic cancer with chemotherapy.

Both primary hepatoma and amebic liver abscess are probably the most common space-occupying disease of the liver in Korea, and the importance of their accurate distinction can not be overemphasized. Radiogold hepatoscanning has been widely used at St. Mary's Hospital, and recently blood disappearance rate of colloidal $^{198}Au$ has been introduced in the study of hepatic ailments. A review of the literature revealed few previous publications concerning the differential features of the two conditions although some characteristic scan findings of each condition have been described. The present study is aimed at a critical review and analysis of various photoscan findings and blood disappearance rate determinations of colloidal $^{198}Au$ of 34 cases of primary hepatoma and 30 cases of amebic liver abscess. Among many scan manifestations, prominence of the uninvolved liver tissue, "hemispherical cold area," and splenic uptake are much more commonly encountered in primary hepatoma and the blood disappearance rate tends to be far more frequently delayed in primary hepatoma than in abscess providing at least a statistically useful basis of distinction of the two diseases.

Unexpected renal abnormality can be detected on bone scan using Tc-99m-MDP. The purpose of the study is to evaluate the diagnostic significance of diffusely increased bliateral renal uptake on bone scarf. 1,500 boor scan were reviewed and 43 scans which showed diffusely increased bliateral renal uptake were selected for analysis. Laboratory findings for renal and liver function tests including routine urinalysis were reviewed in 43 patients. 26 of 43 case showed abnormality in urinalysis and renal function stud 20 of 43 cases showed abnormal liver function study and 3 of these cases were diagnosed as hepatorenal syndrome later. 13 of those 20 cases had liver cirrhosis with or without hepatoma. 12 of 43 cases showed abnormality both in renal and liver function studies. 2 of 43 cases showed diffusely increased bilateral renal uptake after chemotherapy for cancer but not on previous scans before chemotherapy. 2 of 43 cases showed hypercalcemia and 8 of 43 cases had multifocal bone uptake due to metastasis or benign bone lesion. but the latter showed no hypercalcemia at all. There was no significant correlatrion between increased renal uptake and MDP uptake in soft tissue other than kidneys. This study raised the possibility that the impaired liver and/or renal function may result in diffuse increase of bliateral renal uptake of MDP of unknown mechaninsm. It seems to need further study on this correlation.

Sixty-nine patients with diffuse lung uptake of $^{99m}Tc-tin$ colloid were evaluated to determine the kinds of associated diseases, the incidence of associated liver scan abnormalities, and prognosis. The results were as follows: 1) Diseases associated with diffuse lung uptake included malignancies in 31 patients, infectious diseases in 19, chronic liver diseases in 14, and others in 5. It appeared that the marked degree of lung uptake was associated with severe diseases. 2) Thirty-one of the 69 patients(45%) had abnormal liver size, 43(62%) had space occupying lesions or nonhomogeneity in liver image, 37(54%) had splenomegaly and 45(65%) had increased splenic uptake. Increased bone marrow uptake was found in 48(70%) and renal uptake in 15(22%). As the degree of lung uptake increased, there was a statistically significant (p<0.05) tendency for the incidences of the abnormal liver image and renal uptake to increase. 3) Sixty-two of the 69 patients were followed up for one to 439 days(mean 44 days) after liver scanning. Eleven(18%) were dead, 10(16%) were aggravated, and 13(21%) were improved. Most of improved patients had infectious diseases. It appeared that diffuse lung uptake of $^{99m}Tc-Tn$ colloid was found in the various diseases including malignancies, infections, and chronic liver diseases, and that it was strongly associated with other liver scan abnormalities, but was not necessarily associated with a poor prognosis, particularly when underlying diseases were infections.
