    Notes: Abstract Conflicting data have been reported on the incidence of myocardial abnormalities after mediastinal irradiation for Hodgkin's disease. We studied myocardial perfusion in 31 clinically asymptomatic patients (13 male, 18 female, mean age 35 years) 7 years (range 3–11 years) after mantle field radiotherapy. Thallium-201 tomoscintigraphic data were obtained after exercise, 4 h later and at rest (8–15 days later). Images were analysed visually and quantitatively (sectorial quantification of 201T1 uptake on the bull's eye images of the short-axis slices) compared with those of 35 subjects with a low likelihood of coronary artery disease. Twenty-five tomographic data sets were available. Images were visually abnormal in 21 patients (84%) showing an heterogeneous 201Tl uptake. In 68%, the sectorial 201Tl uptake was lower than the mean 201Tl uptake value minus 2 standard deviations measured in subjects with a low likelihood of coronary artery disease. Significant redistribution (quantitatively assessed ≥ 10%) was present in 10 patients (40%). In most of the patients, the location and the shape of the defect(s) could not be anatomically related to an epicardial coronary vessel disease. These results indicate that after mediastinal irradiation the 201Tl myocardial uptake is frequently abnormal. The observed patterns suggest a disease of the small coronary vessels and/or the existence of a myocardial fibrosis rather than epicardial coronary artery disease.

    Diagnosis of malignancy in thyroid nodules by factor analysis of spectral and dynamic structures: a simultaneous dual-isotope dynamic study with thallium-201 and iodine-131 (1992)

    Notes: Abstract The aim of this study was to identify malignant thyroid nodules using iodine-123 and thallium-201 simultaneous dynamic acquisition. The image sequences acquired were processed by factor analysis of spectral and dynamic structures (FASDS). Some 49 patients were investigated, and their diagnoses were confirmed by histological examination. Data processing enables the estimation of the spectra of the two isotopes and the evaluation of the kinetics and spatial structures related to each tracer. The superimposition of thallium and iodide sum images allowed us to delineate the nodule accurately. Two groups were defined: 21 patients who had 201T1 uptake in the nodule, and 28 who had none. In the first group, 5 nodules were carcinomas, whereas all nodules in the second group were benign. The results of the 201T1 dynamic study improved the diagnosis of carcinoma as the number of false-positive cases decreased. FASDS succeeds in extracting spectral and kinetic information, proving its usefulness in clinical diagnosis.

    131I rose bengal: Its use in the evaluation of infantile jaundice (1981)

    Notes: Abstract One-hundred ten 131I-rose bengal studies (RBI) were performed in infants suspected of having biliary atresia. Fecal RBI excretion of less than 10% was observed in 72 of 73 cases of extrahepatic biliary atresia, but also in 10 of 37 cases of intrahepatic cholestasis of various origins. One-hundred twenty-two RBI tests were performed in children operated on for extrahepatic biliary atresia and 71 tests were performed between postsurgical weeks 3 and 8, and 51 tests were done later. Prognostically, early tests show that fecal RBI excretion of more than 15% was observed in 2 of 34 cases who were later completely jaundice-free and in only 1 of 37 cases where no bile flow restoration occurred.

    Biliary pain in postcholecystectomy patients without biliary obstruction (1991)

    Notes: Abstract Biliary pain without obvious biliary obstruction is common in postcholecystectomy patients. We studied 20 symptomatic patients with episodes of biliary-type pain after cholecystectomy (all having undergone endoscopic retrograde cholangiography), and in 18 asymptomatic postcholecystectomy controls. We performed quantitative hepatobiliary radionuclide analysis with dimethyl-imidodiacetic acid. From a series of 90 dynamic images at 1-min intervals using a gamma camera coupled to a computer, time-activity curves were produced in regions of interest in the liver, intrahepatic biliary tree, common duct, and heart, from which quantitative biliary excretion indexes were obtained. The results demonstrate a biliary kinetic dysfunction in patients with postcholecystectomy pain without morphological abnormalities.

    Significance of intra- and extrahepatic portasystemic shunting in survival of cirrhotic patients (1981)

    Notes: Abstract Survival and incidence of hemorrhage and encephalopathy were studied in 121 medically managed cirrhotic patients according to the type of naturally occurring portasystemic shunting. Three types of shunting were distinguishable using scintillation splenoportography, a method whereby morphological and hemodynamic data on portal and hepatic circulation were obtained by external detection. The three patterns were: (1) extrahepatic shunting with partial splenic blood flow diversion, (2) spontaneous total splenic blood flow diversion, and (3) intrahepatic shunting corresponding to portohepatic communications with a diameter larger than 10 μm. The probability of 4-year survival was much lower in case of portasystemic shunting (18%) than in its absence (73%,P〈0.01). Patients with intrahepatic shunting had a survival rate not significantly different from that of patients with extrahepatic shunting. However, they had the highest incidence of hemorrhage (71%), and hemorrhage was not due to rupture of esophageal varices. The highest incidence of encephalopathy was seen in patients with total splenic blood diversion (40%), but it was not significantly different from that of other cirrhotic patients. No group of patients can be significantly identified as a high-risk group.
