  • Correlation between the blood clearance half time and findings of liver scan using the colloidal radiogold in patients of liver cirrhosis is observed through the scoring system, in which the more changes in size, shape and density in the liver scan, the more points are given (table 1). Results: 1) Within the increase in severity of hepatocellular dysfunction in liver cirrhosis, the degree and frequency of following changes in liver scan (done with colloidal radiogold) were increased in order. a) generalized hepatomegaly b) enlargement of the left lobe & reduction of the right lobe c) relatively increased radiodensity in the left lobe and 4) visualization of spleen. 2) Frequency of the normal scan in liver cirrhosis was $12{\pm}3.56%$, frequency of normal value in blood clearance half time of the radiogold was $5.0{\pm}2.34%$ and frequency of normal scan & normal blood clearance rate in liver cirrhosis was $3.6{\pm}2.06%$.

  • The purpose of this study was to develop a method by which the sensitivity of radionuclide liver imaging for detection of liver cirrhosis could be enhanced. Dynamic blood flow scan were performed 21 cases of liver cirrhosis patients by using computerized gamma camera named arterialization index. The results were as follows: 1) Arterialization index were higher in liver cirrhosis comparing to normal value 0.33 and its mean is 2. 02. 2) Comparing to static liver scan, higher sensitivity in dynamic hepatic blood flow scan for detection of liver cirrhosis. Sensitivity for detection of liver cirrhosis is over 90%. 3) There are no correlation between arterialization index and serum albumin level. The use of hepatic dynamic blood flow scan proved effective in detection of liver cirrhosis. However, the test may be used as an aid in distinguishing between normal and pathologic livers.

  • Technetium-labeled phosphate bone scan was shown to detect bone fractures and bone metastasis in early stage than general radiographs. Therefore, bone scan has become one of the most frequently performed nuclear medicine imaging examination. However, non-osseous radiopharmaceutical uptake on the bone scan are unusual findings. We report a case of diffuse splenic absorption of Tc-99m dicarboxypropane diphosphonate in patients who undergo liver transplantation.

  • In an endeavor to help understand some typical scan findings and portal hemodynamics in liver cirrhosis, several commonly occurring scan changes and esophageal varices as demonstrated by esophagram were correlated one another from quantitative and qualitative stand points. Clinical materials consisted of 34 patients with proven diagnosis of liver cirrhosis and esophageal varices. Liver scan was performed with colloidal 198-Au and the changes in the size and internal architecture of the liver, splenic uptake and splenomegaly were graded and scored by repeated double-blind readings. The variceal changes on esophagrams were also graded according to the classification of Shanks and Kerley following modification. Of 34 patients, 91% showed definite reduction in liver volume (shrinkage) constituting the most frequent scan change. The splenic uptake and splenomegaly were noted in 73.5 and 79.4%, respectively. The present study revealed no positive correlation between the graded scan findings including shrinkage of the liver, splenic uptake or splenomegaly and severity of variceal changes of the esophagus. Exceptionally, however, apparently paradoxical correlation was noted between the severity of mottlings and varices. Thus, in the majority (73.5%) of patients mottlings were either absent or mild. This interesting observation is in favor of the view held by Christie et al. who consider the mottlings to be not faithful expression of actual scarring of the cirrhotic liver. This also would indicate that variceal changes are to be the results of intrahepatic arteriovenous shunting of blood with hypervolemic load to the portal system rather than simple hypertension secondary to fibrosis and shrinkage.

  • For this study, the authors obtained and examined anterior views of the liver and spleen in two different positions, upright and supine, of 39 normal subjects and 20 patients with hepaticpathology by means of $^{99m}Tc-colloid$ and gamma camera. This examination confirms the following findings. In general, it is shown, left lobe of the liver in upright position becomes longer in height than in supine position, while the distance between lateral margin of the liver and that of the spleen becomes father in with in supine position than in upright position. The upper margin of liver moves more downward in upright position than in supine. It is noticeable that as for 5 cases with severe chronic liver disease, there is minimal alteration of the liver shape between in two positions. The comparison of the both positions for the better liver scan shows the following finding. Prominent caudate and/or left lobe are marked in the upright position in 16 cases out of the total 59, while none is found in the supine. The false cold area in lower part of the liver disappears in 7 cases in the upright position, while only one shows the disappeance of the false cold area in the supine. Left liver margin due to close contact of spleen is blurred in 3 cases in the upright position. In total 23 cases out of 59 support that the upright position is better for the liver scan, while only 4 cases support the supine position is better. These findings support two assumptions. One is that upright view can bo expected more improved resoluton than supine view for liver scan. Second is that minimal change of the liver shape in both views indicate the serious abnormality in the liver.

  • A 73-year-old male visited our hospital with a complaint of general weakness. He underwent pyloric preserving pancreas-toduodenectomy due to ampullary cancer three years ago. Abdominal computed tomography scan at initial visit revealed multiple hepatic masses. A PET-CT scan showed multiple FDG uptakes at whole liver. He underwent hepatic artery infusion chemotherapy (HAIC) for five cycles. During the first cycle of HAIC, he developed gastric ulcer bleeding and endoscopic hemostasis was done successfully. Esophagogastroduodenoscopy after the 5th cycle of HAIC revealed ulcer scar at gastric angle. PET-CT scan at 12 months showed no FDG uptake at liver, but a focal FDG uptakes at stomach and peri-gastric lymph nodes were newly developed. Esophagogastroduodenoscopy revealed about 3 cm sized mass at gastric angle. He underwent surgery and pathologic examination revealed large cell neuroendocrine carcinoma. We report a case of gastric large cell neuroendocrine carcinoma with liver metastasis treated with HAIC followed by surgery.

  • A twenty-one-year-old man visited our hospital due to abdominal distension for a month. On the physical examination, there was severe abdominal distension with fluctuation and shifting dullness. The routine laboratory results were within normal range. On the Magnetic Resonace angiography, there wasn't any blood flow within the right and middle hepatic vein. So we concluded that the etiologic disease was Budd-Chiari syndrome. On the liver scan, there was cold area(absence of radiouptake) on entire right lobe of the liver, increased uptake on the bone marrow and showed splenomegaly. This finding was similar to the liver mass occupying right lobe with underlying chronic liver disease. On the previous reports, it is quite uncommon finding that Budd-Chirari syndrome shows lesion like space occupying one on the liver scan. So we report this case with a review of the literature.

  • In the past few years, scintigraphy has become increasingly important in clinical practice, and the use of a color-printing technique has permited a more accurate interpretation of the scan image. Our liver color scintigrams consist of 51 hepatomas, 35 liver cirrhosis, 22 liver abscessis, 10 hepatitis and other 13 cases of the liver diseases which were clinically arid pathologically diagnosed at Sevarance Hospital, Yonsei Univ., since Feb. 1969 through Sept. 1969. These scintigrams have been analized in terms of various pathologic morphology, such as size, shape, margin of the liver, distribution of radioactivity, and shape of the space occupying lesions. The results are as follows: 1. Enlargement of the liver was the most common finding in the diseased livers. The Rt. lobe enlargement was particularly prominent in the liver abscess. 2. Irregular distribution of radioactivity in the liver (so called mottling) was present in 78% of hepatoma, while it was seen only in 31% of liver abscesses. 3. Liver cirrhosis tends to show perihilar accumulation of the isotope (57%). 4. The deformity of the lower most angle of the Rt. lobe, and the Lt. lateral margin of the Lt. lobe was also impressive throughout the cases ($74{\sim}95%$ of all diseased livers). 5. The frequency of visualization of the spleen was influenced by the size of space occupying lesions and the amount of functioning liver. 6. Differentiation between the liver abscess and hepatoma seems to be possible on scintigram, when shape and margin of defect and patterns of distribution of radioactivity in the remaining liver are clearly demonstrated.

  • Hepatoscintigram has been a useful diagnostic method for the liver diseases since 1953, but reasonable diagnostic criteria for parenchymal liver diseases are not yet accurately established. For the purpose of searching for more advanced diagnostic criteria for various types of live disease by the liver scan, a retrospective study was made of 272 cases who underwent both hepatoscintigram with 198 Au colloid and liver biopsy in Hanynag University Hospital from Jan., 1978 to Dec., 1981. The results were as follows: 1. Fuzzy margin (irregular indentation of the liver margin) in the hepatoscintigram was noted in 226 cases (97.79%). 2. Of 35 cases with fuzzy margin only, 28 cases (80%) revealed mild parenchymal liver disease, such as acute hepatitis or chronic persistent hepatitis by the liver biopsy. 3. Mottling change (209 cases) was always accompanied by fuzzy margin except only one case, and 31 cases (86.1%) of fuzzy and mottling cases (36 cases) showed mild parenchymal liver disease. 4. Configuration change (193 cases) was usually accompanied with other changes and espicially 104 cases had configuration change with fuzzy and mottling changes. 73 cases (88.44%) of 86 cases with severe configuration change revealed advanced parenchymal liver disease on biopsy. If liver scan showed mild configuration change, we could not decide the type of liver disease only liver scan, and so further studies are needed. 5. Splenic uptake was noted in 34 cases (40.48%) of 84 cases with advanced parenchymal liver disease, and the degree of splenic uptake was for the most part morderate or severe; whereas splenic uptake was noted in 18 cases (16.51%) of the mild parenchymal liver disease (109 cases), and the degree of splenic uptake was largely mild.
