CT is a noninvasive and highly valuable method in the diagnosis of intracerebral vascular accidents. Authors analysed 200 cases of clinically suspected cerebrovascular accident(CVA) who were performed CT scan from April1980 to June 1981. The results were as follows; 1. The analysis of CT finding in 200 cases of clinically suspected CVA showed 129 cases (64.5%) of definite CVA, 53 cases of normal finding, 8 cases of equivocal finding and 10cases of miscellaneous disease. 2. Among CVA positive finding of 129 cases, intracerebral hemorrhage was noted in61 cases (47.3%), cerebral infarction in 39 cases (30.2%) and subarachnoid hemorrhage in 29 cases (22.5%) 3. The most prevalent age group as 6th decade in intracerebral hemorrhage and subarachnoid hemorrhage, but 7th decade in cerebral infarction. The sex ratio between male and female in intracerebral hemorrhage and subarachnoid hemorrhage was 1:1 and 1:1.6 respectively, but incerebral infarction male was predominant with the ratio of 3:1. 4. The most common sites of involvement was basal Anglia (41.0%), thalamus (32.8%) and lobes(18.0%) in intracerebral hemorrhage; and lobes(51.6%) and basal ganglia (30.7%) in infarction. 5. Among 33 cases of subarachnoid hemorrhage confirmed by spinal tapping, 25 cases (75.8%) showed CT positive finding and 8 cases (24.2%) CT negative finding. Most cases of CT positive finding were performed CT scan was 7 hours after onset; and the mass effect of the lesion was observed in 44% of cases, mostly(82%) within a week. The contrast enhancement of the cerebral infarct was demonstrated in 19% of cases mostly between 3 days and 30 days and after onset.

In the diagnosis of bile duct carcinoma, oral or intravenous cholangiography is of no air in the majority ofpatients with bile duct carcinoma who are jaundiced. Recently ultrasonography and CT are widely used for evalutionof biliary disease, but direct visualizing methods of the biliary tract by ERCP and PTC gives more detailed information and exact localization of the lesion. ERCP is less invasive and dangerous and has some more advantages than PTC. We analyzed 33 cases of confirmed extrahepatic bile duct caracinoma who were performed ERCP. The resultswere as follows; 1. The 7th decade was the predilection age, and the radio of male to female was 3.:1. 2. Thelocations of extrahepatic bile duct carcinomas were common bile duct in 45.5%, common hepatic duct in 27.3%,junction of cystic duct and widely extended in 12.1% respectively and junction of hepatic duct in 3.05 in order offrequency. 3. ERCP finding of extrahepatic bile duct carcinomas revealed complete obstruction of bile duct in mostcases, and irregular margined protuberant type was more common than smooth margined constricted type atobstruction site. 4. ERCP finding according to the location of lesion showed that protuberant type was relativelyfrequent in common bile duct and constircted type in common hepatic duct respectively.

The differentiation between lung abscess and empyema can be difficult, but has important therapeuticconsequences. Thoracostomy tube drainage is essential therapy for an empyema, whereas prolonged antibiotic therapyand postural drainage often suffice for a lung abscess. Conventional radiographic findings are usually relied onto help make correct indfferentiation between empyema and lung abscess, but overlying lung disease or unfavorablelocation of lesion often results in ambiguous findings. Although ultrasound has proved useful in differentiatingempyema from lung abscess, CT is best accurate diagnostic method. Authors reviewed chest CT of 50 cases(41empyemas, 9 lung abscesses)which were diagnosed by suegery or clinical background during the period from May 1980to June 1985 at Dongsan Medical Center, Keimyung University. The results were as follows: 1) Age and sexdistribution a) Empyema: The incidence was most common in the 6th and 7th decades. Male to female ratio was 3:1.b) Lung abscess: The incidence was most common in the 5th, 6th and 7th decades. Male to female ratio was 2:1. 2)Wall characteristics(empyema 32 cases, lung abscess 9 cases): The 9 cases of 41 empyemas had not defined theirwalls. a) Empyema had at least a part of their wall that was thin (81%), uniform width(84%), and smooth on bothmargins (more than 96%). b) The wall of lung abscess was thick (89%), and irregular margins(100%). 3) Separationof uniformly thickened visceral pleura from parietal pleura("split pleura" sign) was seen only in 68% of allempyemas. 4) Adjacent lung compression was seen only in 88% of all empyemas. 5) Chest wall angle: In 78% of allempyemas had obtuse or mixed angles, wherease in 85% of all lung abscesses had acute angle. 6) Shape oflesion:Empyema had variant shapes from round to crescent, however all lung abscesses had round or ovoid shape. 7)Size of lesion: In 85% of all empyemas had medium(41%) or large (44%) size, but the lung abscess had onlysmall(33%) or medium (67%) size. 8) Air in lesion was seen in 41% empyemas and in 89% lung abscesses. 9) Adjacentlung consolidation showed in 34% empyemas and in all lung abscesses. 10) Free pleural fluid was seen in 12%empyemas and in 89% lung abscesses. 11)Septated lesions were seen in 32% empyemas and in 56% lung abscesses. 12)Multiple lesions were seen in 44% empyemas and in 55% lung abscesses. 13) Mediastinal shifting was seen in 49%enpyemas and in 44% lung abscesses, but which all lung abscesses were coexisted with empyemas. 14) Pleuralcalcification was seen only in 5 cases(12%) of all empyemas. 15) Location of leison: Most(93%) of empyemas werelocated in posterolateral portion of hemithorax, and most (78%) of lung abscesses involved in right lower lobe.
