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.

Background and Objective : Dural sinus thrombosis(DST) is a rare disorder with many etiologies and unpredictable clinical courses. The optimal mode of treatment has not been well established. With the advent of neuroradiological intervention, we have successfully performed the direct infusion of t-PA into the venous sinus for the prompt Iysis of thrombosis and subsequent clinical Improvement. METHODS: Three patients, presented with headache, vomiting or focal neurological deficits, were diagnosed as having dural sinus thrombosis by MRI. After the confirmation by angiogram with a superselective transfemoral catheter, a bolus of t-PA was injected into the thrombosed portion of the dural sinuses, followed by a continuous t-PA infusion at a rate of 40mg/hr. Result : All three patients were clinically improved. Follow-up angiogram on the next day demonstrated recanalization of the thromboses venous sinus. Two patients developed non-life threatening extracranial hemorrhage as a complication. Conclusion : Authors suggest that direct thrombolysis with t-PA is a very effective method of treatment in the early phase of DST. Further study is needed to decide the appropriate t-PA dosage to minimize the complication.

The vaso-epididymography and vasoseminal vesiculography is the only diagnositc method for investigating thepatency and abnormal lesion of male genital system radiologically. The author performed 53 cases ofvaso-epididymography and vasoseminal vesiculography in Busan National University Hospital during the 8 years from1973 to 1981. All patients complained of primary infertility more than a year and were confirmed azoospermia onsemen examination, and 23 cases of them underwent testicular biopsy. The results are as follows; 1. The agedistribution were mainly between 26 and 35 years old (83.0%). 2. The infertile duration were almost from 1 to 5years(86.8%). 3. The past history associated with infertility was gonorrhea, tuberculosis and scrotal trauma. 4.Of the 23 cases of confirmed by testicular biopsy, the pathologic findings were normal spermatogenesis in 12 cases(52.2%) and hypospermatogenesis or arrest type in 11 cases (47.8%). 5. Non-filling sites of contrast media onvas-epididymography and vasoseminal vesiculography were epididymis(83.0%), ejaculatory duct (41.5%) and seminalvesicle (24.5%), were commonly bilateral (68.0%) and were more prevalent in the right side than left (1.2:1.0). 6.The abnormal findings of ejaculatory ducts, seminal vesicles, vas ampullas and vas deferens were mainly strictureof obstruction, obstruction of dilatation, beaded appearance or obstruction and obstruction respectively. 7. Inthe epididymis, there was almost obstructive lesion at the tail portion(83.0%).

The lymphoepitheliomalike carcinoma of the cervix is histologically similar to lymphoepithelioma of the nasopharyngeal region or medullary carcinoma of the breast which has grossly circumscribed, histologically poorly differentiated nonkeratinized squamous cell carcinoma with prominent stromal inflammation. Although the entity has been rarely reported in the united states, it has been reported relatively common in Japan. The Japanese literature suggests that patient with this varient may have a more favorable prognosis when compared with the usual squamous cell carcinoma of the cervix A patient with a squamous cell carcinoma of the uterine cervix with marked lymphocyte and plasma cell infiltration is reported and the literature reviewed.

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.

The causes of pneumomediastinum during perioperative period are trauma to the airway from intubation or other manipulation, raised airway pressure during anesthesia, rupture of a bleb or other intrapulmonary lesion, upper airway damage during neck surgery, infiltration of the tonsillar fossa or adenoid bed with air under pressure, increased airway pressure after nausea and vomiting, and coughing during awakening. This paper is represents and discusses a case of pneumomediastinum, pneumothorax, extensive subcutaneous and retroperitoneal emphysema which occurred suddenly a few minute after several times of bucking and straining in the intubated state with oxygen catheter after tonsillectomy and adenoidectomy at recovery room. The complieation was thought to be a infiltration of air through tonsillar fossa under pressure or alveolar rupture due to increased airway pressure after coughing. The patient was treated with high concentration of oxygen and recoverd uneventfully.

PURPOSE: To assess the role and efficacy of radiologic intervention in the adult patients with esophagobronchial fistula. MATERIALS AND METHODS: Radiologic intervertion was performed in 4 patients with esophagobronchial fistula. We tried direct occlusion of fistula tract by glue(histoacylate 0.4cc + lipiodol 0.3cc) and coil in 2 patients and performed presurgical wire insertion by using 8F curved catheter via esophageal opening of fistula tract. The latter procedure was carled out to detect the fistula tract easily at operation. RESULTS: Direct occlusions of fistula tract by glue and coil were performed only to fail in 2 patients. Pre-surgical wire incertion by using 8F curred catheter under guidance of fluroscopy in 3 patients were helpful in detecting fistula tract at operation. CONCLUSION: Direct occlusion of the fistulous tract in esophagobronchial fistulas was ineffective. However, presur- gical wire insertion by using cured catheter under fluroscopy guidance is helpful to detect the fistula tract easily at operation.

PURPOSE: Lipiodol CT is a important modality for the diagnosis of hepatocellular carcinoma and compared is usually performed at 2-3 week after Lipiodol injection. Therefore, we assessed and the diagnostic value and merits of immediate CT after chemoembolization from there of 2-3 week delayed Lipiodol CT. MATERIALS AND METHODS: Thirty three cases of chemoembolization which were performed both immediate CT after chemoembolization and 2-3 week delayed Lipiodol CT were reviewed retrospectively. They were divided into four grades according to pattern of lipiodol uptake by three radiologists. The diagnostic value of immediate Lipiiodol CT was compared to delayed Lipiodol CT. RESULTS: Grade 0 was two cases(3.0%) and Grade 1 was seven cases(21.2%). In the cases of Grade 2(23/33, 69.7%) tumor uptake could be dishng wished from parenchymal uptake of Lipiodol by its density and pattern. Tumor uptake showed dense and homogeneous pattern, but parenchymal uptake revealed less dense and hepatoram-like wedge shaped pattern. Lipiodol uptake of tumor in Grade 3(1/24, 3.0%) was equal to that in delayed Lipiodrl CT. Grade 3 and 2(72.7%) of the immediate Lipiodol CT were not inferior to delayed Lipiodol CT in its diagnostic value. CONCLUSION: The immediate Lipiodol CT could make rapid establishment of treatment plan and are expected to be more convenient than delayed CT for the patients.
