Femoral arteriography has assumed in recent years a greater clinical and surgical significance, especiallysince the advent of arterial grafting for occlusive arterial disease. Evaluation of the site and extent ofocclusion, the state of distal arterial tree and degree of collateral circulation can best be obtained byserialographic studies. Authors analyzed 28 cases of clinically and radiologically diagnosed Buerger's disease inGURO hospital radiology, College of medicine, Korea university, during last 6 months from March to August, 1984.The results are as follows; 1. The age distribution were between 20 and 50 years old, and most commonly involvedage group was 20-29. 2. The most frequent finding was the obstruction of peripheral artery with or withougcollateral vessel and almost all patient had occlusion more than 1 segmental branch. 3. The most frequentlyinvolved arteries in Buerger's disease were trifurcation area below the knee joint, anterior and posterior tibialartery and peroneal artery. Peroneal artery was less commonly involved than anterior or posterior tibial artery.

PURPOSE: To develop an efficient journal searching program. MATERIALS AND METHODS: A graphic user interface oriented program was developed with Microsofts Access 2.0 and its Deveolper Tool Kit under the Windows system. The program needed four floppy diskettes {4.5 megabyte) for in stallment. With the author, title, journal name, volume and pages, index words, and abstracts from JKRS and JKSMU as the input data, the utility of the program was tested for its journal searching ability in 486 DX II with 8 megabyte main memory. RESULT: The author, titlie, index word, abstract, and variable queries were carried out from 3,200 articles within 13 seconds. The test of the program satisfied and useres, radiologists, and physicians. CONCLUSION: The program is recommended for seaching of journals as it is very eary to use and userfriendly.

In the intestinal perforation during hydrostatic reduction for intussusception, the diluted isotonic Gastrografin may prevent body fluid shifting to peritoneal space, and granulomatous reaction resulting in intestinal obstruction, which can be induced by Barium on the peritoneal surface. We have experienced two perforations from 563 Gastrografin reductions during the last five years. One of the perforated cases had no complication on one year follow up after ileocecectomy, but the other, who was in the state of shock before the reduction, died at 133rd day after the operation. The cause of death was aspiration during the feeding. We report the above two cases of intestinal perforation by Gastrografin reduction without evidence of fatal complication.

PURPOSE: To compare the feasibility and safety of US-guided right and left percutaneous transhepatic biliary drainage (PTBD). MATERIALS AND METHODS: Between March 1998 and May 1999, 32 patients underwent 36 US-guided right or left PTBD in referred order, alternatively. The causes of biliary obstruction were bile duct stone (n=2), bile duct carcinoma (n=10), carcinoma of the pancreas (n=9), GB carcinoma (n=7), metastasis to the porta hepatis (n=3), and carcinoma of the ampulla of vater (n=1). Technical success, procedure time, fluoroscopic time, and complications were evaluated. RESULTS: PTBD was successful in 94% of both right and left approach. The average procedure time was 9.7+/-3.8 min. in the right approach and 9.6+/-3.1 min. in the left approach, respectively (p=0.794). The average fluoroscopic time were 3.9+/-2.4 min. in the right approach and 3.8+/-2.2 min. in the left approach (p=0.892). A major complication, bile peritonitis, occurred in one of 16 patient with right-sided approach. Minor complications occurred in six right (2 hemobilia, 3 tube malfunction, 1 cholangitis) and three left (1 hemobilia, 1 fever, 1 cholangitis) PTBD. There were no significant difference in the complication rates between right and left PTBD (p=0.729). CONCLUSION: There were no significant differences in feasibility and safety in US-guided right and left PTBD.

It is difficult to distinguish an islet tumor originating from heterotopic pancreas tissue from the other submucosal tumors. Although the malignant transformation of a heterotopic pancreas, including islet cell tumor, is extremely rare, it remains an important consideration in the differential diagnosis of duodenal submucosal masses. We have demonstrated the radiologic appearance and the clinical-pathologic findings of a highlighted, rare case of islet cell tumor arising from a heterotopic pancreas in the duodenal wall.

PURPOSE: To evaluate the extrahepatic spread of peripheral cholangiocarcinoma with CT. MATERIALS AND METHODS: We retrospectively reviewed CT findings of extrahepatic spread in thirty-six patients with peripheral cholangiocarcinoma confirmed adenocarcinoma at surgery(n=5) or percutaneous biopsy(n--31) without primary leion in other organs, and analysed the frequency and distribution of enlarged lymph nodes, direct invasion of adjacent solid organs, and thrombosis of major vessels. RESULTS: Among the 36 cases, enlarged metastatic lymph node was noted in twenty-four(66.7%), direct invasion into adjacent organs in six(16.7%), portal and inferior vena caval thrombosis in five(13.9%). Enlarged lymph nodes were seen in hepatic nodes(n=16, 44.4%), portocaval nodes(n=15, 41.7%), interaortocaval nodes (n=10, 27.8) and celiac nodes in two(5.6%). Direct invasion was detected in the greater omentum(n=6), gallbladder(n:3) and stomach(n=2). Portal vein thrombosis(n:5) and thrombosis of inferior vena cava(n=2) were noted. CONCLUSION: Lymph node metastasis was seen in 67% in patients with peripheral cholangiocarcinoma. Direct invasion to adjacent organs and thrombosis in portal vein or inferior vena cava were occasionally associated.

PURPOSE: To determine the appropriate size of a short and long-term storage device, bearing in mind the design factors involved and the installation costs. MATERIALS AND METHODS: The number of radiologic studies quoted is the number of these undertaken during a one-year period at a university hospital with 650 beds, and reflects the actual number of each type of examination performed at a full PACS hospital . The average daily number of outpatients was 1,586, while that of inpatients was 639.5. The numbers of radiologic studies performed were as follows: 378 among 189 outpatients, and 165 among 41 inpatients. The average daily number of examinations was 543, comprising 460 CR, 30 ultrasonograms, 25 CT, 8 MRI, and 20 others. RESULTS: The total amount of digital images was 17.4 GB Per day, while the amount of short-term data with lossless compression was 6.7 GB Per day. During 14 days short-term storage, the amount of image data was 93.7 GB in disk array. The amount of data stored mid term (1 year), with lossy compression, was 369.1 GB. The amount of data stored in the form of long-term cache and educational images was 38.7 GB and 30 GB, respectively. The total size of disk array was 531.5 GB. A device suitable for the long-term storage of images, for at least five years, requires a capacity of 1845.5 GB. CONCLUSION: At a full PACS hospital with 600 beds, the minimum disk space required for the short-and mid-term storage of image data in disk array is 540 GB. The capacity required for long term storage(at least five years) is 1900 GB.
