Illuminating type poster looks very impressive and one may feel as if it were on the view box in his readingroom. Some difficulties and nuisances really exist in making them and a few of demerits can also be encounteredthat of contrast enhancement and of rough graininess. Contact print renders the best quality, though, KodakTechnical-Pan film with HC-110 (Dil. F) developer, llford xp 1–400 with Kodak C-41 color developer and KodakPlus-X with Microdol-X developer combinations also work in minimizing the deterioration of resolution and grainisswhich can almost always occur in enlargement prints.

Pecutaneous transhepatic portogram with selective catheterizatio of the portal vein and its tributaries notonly provide information about the status of portal circulation and but can also be used in the treatment ofbleeding esophageal varices by selective embolization with various embolic materials. The authors describe easierand safer modified method of conventional percutaneous transhepatic portogram. We wish to describe our experiencewith the technical aspects and portosystemic collateral patterns in 26 patients with variceal bleeding, from July1985 to July 1986 at Kyungpook National University Hospital. 1. To overcome the difficulties of catheter passageand superselection of variceal supplying vein, we used 7F sheath directly introduced over the ,018″ guide wire.We used coaxial system using 25cm 18G needle within 7F vessel dilator to make the tip of dilator more rigid. 2.Variceal obliteration attempted in 23 patients who showed variceal supplying veins on the protogram, Successfulobilteration was obtained in 20 patients. We used absolute ethanol, stainless steel coil, and Gelfoam cubes withsclerosing and embolica agent of variceal vein. 3. Portosystemic collaterals of 24 patients; Coronary vein;21cases, Inferior mesenteric vein:9 cases, Short gastric vein:7 cases, Umbilical & paraumbilical vein; 6 cases,Gastrorenal: 3 cases, Splenorenal: 2 cases, Splenoretoperitoneal: 1 case. 4. The number of coronay vein were 18cases of single and 4 cases of two. The locations of coronary vein: Splenic vein: 13 cases, Main portal vein: 7cases, Junctional area: 6 cases. 5. Transhepatic obliteration of the gastroesophageal veins is a relatively simpleand usually successful form of palliative treatment for actively bleeding and stable gastroesophageal varices.

PURPOSE: To compare the efficacy and safety of CT-guided automated gun biopsy with those of fine needleaspiration biopsy of pulmonary lesions. MATERIALS AND METHODS: Under CT guidance, we performed automated gunbiopsies in 115 cases of 109 patients and fine needle aspiration biopsies in 119 cases of 108 patients withpulmonary lesions. Between the two methods, we compared the diagnostic rate, diagnostic accuracy and frequency ofcomplications according to the depth and diameter of pulmonary lesions. RESULTS: The overall diagnostic rates ofautomated gun biopsy and fine needle aspiration biopsy were 76.5% (88/115) and 64.7% (77/119) respectively. Therewas a significant statistical difference (p=0.048), especially in the case of malignant lesions less than 3 cm(p=0.027) and more than 6 cm (p=0.008) in maximal diameter. The diagnostic accuracy of automated gun biopsy andfine needle aspiration biopsy showed significant statistical difference only in malignant lesions more than 6cm inmaximal diameter (p=0.008), and in the lesions located from 1 cm to less than 3cm from the pleura (p=0.030), asseen on CT. There was no significant statistical difference in the frequency of complications. CONCLUSION:Automated gun biopsy of pulmonary lesions under CT guidance is safe, with complications rate comparable to thoseof fine needle aspiration biopsy. A higher overall diagnostic rate can be achieved by automated gun biopsy than byfine needle aspiration biopsy. For the diagnosis of pulmonary lesions under CT guidance, automated gun biopsy istherefore a more useful procedure than fine needle aspiration biopsy.

Sternocostoclavicular hyperostosis is a rare syndrome characterized by hyperostosis and soft tissue ossification between the clavicle and the anterior part of the upper ribs. Since first reported in 1974, the syndrome has been noted predominantly in Japan(1). Our case report describes the disorder and its radiologic manifestations.

PURPOSE: The purpose was to evaluate the procedure-related complications of the TIPS and its clinical significance. MATERIALS AND METHODS: The materials consisted of 52 patients who had 57 TIPS procedures for the management of variceal bleeding due to portal hypertension. To detect the occurrence of complications during transhepatic needle puncture(from hepatic vein to the portal vein), contrast material was injected with the withdrawl of the puncture needle. RESULTS: Procedure-related complications occurred in 28 patients (54%) among 52 patients. The corn lications were biliary tree puncture(15 cases), transperitoneal puncture(14 cases), stent malposition(3 cases) stent migration(1 case), hepatic arteries puncture(1 case), splenic vein perforation(1 case), and paroxysmal tricular tachycardia(1 case). Three patients had acute stent thrombosis with rebleeding immediately after procedure. The procedure was repeated in two patients. One patient was expired due to rebleeding. CONCLUSION: The procedure related complications were clinically insignificant in most instances, when stent thrombosis or proxysmal ventricular tachycardia was developed.

Primary role of ultrasound in patients with thyroid nodule is to determine the multiplicity and detect occult carcinoma. We analyzed US findings of 53 thyroid carcinomas with multiple nodular lesions from january 1988 to december 1991. The results were as follows: 1. 109 malignant nodules in 53 cases and 24 benign in 23 were comfirmed. 2. The nature of the masses were solid in 72 malignant nodules (74.2%), and complex in 25 (25.8%) of which 19 were predominantly solid. 3. The echo pattern of the solid and solid predominant masses were hypoechoic in 78 malignant nodules (80.4%), hyperechoic in 10 (10.3%), and isoechoic in 3 (9.3%) 4. Internal punctate calcifications within the masses were observed in 31 malignant nodules (31.9%). 5. Halo sign was present in 16 malignant nodules(16.5%). 6. The preoperative sonographic diagnosis of thyroid carcinoma was made in 39.4% of 53 cases with multiple nodules on US. In conclusion, the number, and halo formation of nodules were insignificant to differentiate the benign nodule from the malignant. The heterogeneous hypoechoic nodules with size greater than 4cm, multiple stippled calcifications, displacement of the trachea or other surrounding structures of combined lymph node enlargements seem to indicate the possibility of malignancy.

We report the results of field operation of TELEACE system between Kyung-Pook National University Hospital and Ul-Jin Goon Health Care Medical Center from December, 1990 to September, 1991, which had been operated as a kind of Integrated Services Digital Nework projects by KOREA TELECOMMUNICATION Inc. Ul-Jin Goon Health Care Medical Center transmitted 414 plain radiographs to our hospital in speed of 9600BPS. Each image was composed of 1024X1024 pixelsX8 bits/pixel. In our hospital, the image files were displayed on high resolution monitor (1280×1024 pixets). Text files of image interpretations were transmitted to the health care medical center. The two radiologists who had interpreted the transmitted images, went to the health care medical center and read radiographic film with blind test method. We obtained the following results: false negative rate of 6.3%, false postitve rate of 2.4%, mean sensitivity of 81.4%, mean specificity of 96.3%, and mean accuracy of 91.3%. In predictive value of 0.05, there was no significant difference between results of these two types of radiographs. In conclusion, TELEACE system was valuable to the clinicians isolated from services of radiologists.

A patient with a history of asthma underwent computed tomography (CT). With a soft tissue window (width 330, level 30) the scan of the neck did not show any lesion within the airway lumen, but with a lung parenchymal window(width 1300, level -500), we were able to find a low attenuationg endotracheal mass lesion measuring -320HU. A bronchoscopy was performed and a polypoid mass approximately 2cm in diameter was found within the tracheal lumen. An endoscpic biopsy was not performed due to the risk of bleeding and the bronchoscopy was inconclusive for tissue diagnosis. CT, however, provided a definitive diagnosis by demonstrating fat within the tumor on the lung window.
