N/A Radionuclide cardioangiography has been widily applied and has played mjor foles in moninvasive assessment of cardiac function. Three techinques, first-pass gated first and gated equlibrium nethods have commonly been used to evaluate right ventricular ejection fraction which usually abnormal in the patients with cardiopulmonary disease. It has been known that the gated first pass method is most accrate method among the three rechiques in assessment of fight ventricuiar ejection fraction. The radionuclide right ventricular ejection fraction values were determined in 13 normal subjects and in 15 patients with chronic obstructive puimonary disease by the gated first pass method and compared with those of the first pass method because there has been no published data of fight ejection fraction by the gated first pass method were compared with the detas from the pulmonary function test performed in the patients wih chronic obstructive pulmomar desease. The results were as follows; 1) The values of fight ventricular ejection fraction by the gated first pass method were 50.1 +- 6.1% in normal subjects and 38.5 +- 8.5 in the patients with chronic obstructive pulmonary disease. There was statistically significant difference between the right ventricular ejection fraction of each of the two groups (p<0.05) 2) The right ventricular ejection fraction by the gted first pass method was not linearly correlated ith FEV, VC. DLCO. and FVC as well as PO2 and PCO2 of the patients with chronic obstructive pulmonary disease. We concluded that right ventricular ejection fraction by the gated first pass method usingradionuclide cardioangiography may be suseful in clinical assessment of the right ventricular function.

Sternocostoclavicular hyperostosis (SCCH) is a chronic, nonsuppurative inflammatory disease involving sternum, clavicle, upper ribs and its adjacent soft tissue. It is a relatively newly described syndrome, characterized by ossification in the region between the clavicle and the first rib, and hyperostosis of the medial end of the clavicle with simultaneous involvement of the sternum and juxtasterna1 ribs. We experienced one case of sternocostoclavicular hyperostosis, diagnosed by pinhole bone scintigraphy. This paper describes characteristic pinhole scintigraphic findings of SCCH, with comparative study with radiographic and pathologic findings.

N/A Radioaerosol inhalation imaging (RII) has been used in radionuclide pulmonary studies for the past 20 years. The method is well accepted for assessing regional ventilation because of its usefulness, easy fabrication and sirnple application system. To evaluate its clinica1 utility in the study of irnpaired regional ventilation in bronchial asthma, we obtained and analysed RIIs in 31 patients (16 women and 15 men; age ranging 21-76 years) with typical bronchial asthma at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Wledical colle#ge, from January, 1988 to August, 1989. Scintiscans were obtained with radioaerosol produced by a HARC(Bhabha Atomic Reserch Center, 1nc]ia) nebulizer with 15 mCi of Tc-phytate. The scanning was performed in anterior, posterior and lateral projections foIlowing 5-rninute inhalation of radioaerosol on sitting position. The scans were analyed and correlated with the results of pulmonary function study and the findings of chest radiography. Fifteen patients had concomitant lung perfusio#n image with ' Tc-MAA. Follow-up scans were obtained in 5 patients after bronchodilator therapy. 1 he patients were divided into (1) att.ack type (4 patients), (2) resistant type (5 patients), (3) remittent type (10 patients) and (4) bronchitic type (12 patients). Chest radiography showed hyperinflation, altered pulmonary vascularity, thickening of the bron- chial wall and accentuation of hasal interstiti.al markings in 26 of the 31 patients. Chest radiographs were normal in the remaining 5 patients. Regardless of type, the findings of RII were basically the same, and characterized by the deposition of radioaerosol in the central parts or in the main respiratory air ways along with mottled nonsegmental ventilation defects in the periphery. Peripheral parenchymal defects were more extensive than that of expected findings from clinical symptoms, pulmonary function test and chest radiograph. Rroomstick sign was present in 1.7 patients. The abnorrnality of RII was poorly correlated with perfusion scans. In all 5 patients treated with bronchodilators, follow-up study demonstrated a decrease in the degree of radioaerosol deposition in the central air way with improved ventilation defects. This study indicates that RII is a useful technique for the evaluation of regional ventilation abormality and the effect of treatrnent with bronchodilators in patients with bronchial asthma.

N/A It is well known that hepatobiliary agent are taken up by metastatic hepatocellular carcinoma(HCC) as well as primary HCC. But the reported cases of the extrahepatic metastasis of HCC diagnosed by hepatobiliary scintigraphy are for the most part hematogenous ones. The relation of the uptake pattern of hepatobiliary agent in the primary and metastatic HCC is also still remains unknown. So we undertook this study to evaluate the relation of the hepatobiliary scintigraphic patterns of primary and metastatic HCC with different metastiatic routes. Nine patients with primary HCC and twelve cases of metastaic HCC including four lung metastases, one bone metastasis, one right atrial metastasis, one peritoneal wall metastasis, and five lymph node metastases were studied with Tc-99m-DISIDA scintigraphy. The images were taken on 10, 30 minutes, 1, 2, 4-6 hours. The overall detection rates of hematogenous metastases(lung and bone) is 60%(3 of 5), direct metastasis(right atrium and peritoneal wall), 100%(2 of 2) and lymphatic metastases, 0%(0 of 5). In four of five metastatic cases demonstrated with hepatobiliary scintigraphy, biliary agent is also taken up by primary HCC lesions. And the appearing time of the radioactivity in the direct metastatic HCC lesion is same as that of primary HCC and in the cases of hematogenous metastasis, earlier than that of primary HCC. Hepatobiliary scintigraphy is more useful in the diagnosis of the metastatic HCC than primary HCC, in the cases of hematogenous and direct metastasis.

N/A To evaluate availability of cerebral radionuclide imaging for diagnosis of brain death, we examined 25 patients with a suspected clinical diagnosis of brain death. 8 patients were studied by Tc-99m-DTPA and 15 patients were by Tc-99m-HMPAO (Hexamethyl propyleneamine oxime). Seven patients with Tc-99M-DTPA studies revealed absence of cerebral blood flow and sagittal sinus activity. All of 15 patients with Tc-99m-HMPAO studies revealed complete absence of cerebral perfusion. The results of the cerebral radionuclide studies of brain death correlated with other clinical conditions, such as intracranial pressure(ICP), EEG, transcranial doppler sono- graphy(TCDS), and neurologic examination. The ICP of 8 patients, who are confirmed by brain death with Tc-99m-HMPAO study are elevated in all cases. In conclusion, cerebral radionuclide imaging for diagnosis of brain death is available. Tc-99m-HMPAO imaging is unequivocal, easily interpreted, well reflect the physiologic state of increased ICP, and provides adequate assessment of posterior fossa activity. In addition, the SPECT imaging with Tc-99m-HMPAO produces more accurate results due to it's superiority of image contrast and proper localization of radiopharmaceutical distribution than conventional planar imaging.
