The simple chest X-ray study is essential in diagnosis of pulmonary tuberculosis, especially primary pulmonarytuberculosis. Authers analyzed the chest films and tuberculin tests of 521 cases which are suspected primarypulmonary tuberculosis coinically, from Jan. 1978 to Nov. 1982 at Seoul Red Cross Hospital. The results are asfollows; 1. Among the total 521 cases, the 115 cases of chst film reveal 245 probable pulmonary tuberculouslesions. 2. The coincidence of the parenchymal and lymphnodal involvement are observed in 40 cases (34.8%) with137 lesions(55.9%), parenchymal only in 23 cases (20.0%) with 25 lesions(10.2%) and lymphnodal only in 52 cases(45.2%) with 83 lesions(33.9%). 3. In observing the distribution of the 83 parenchymal lesions, the right lung istwo times as common as that of the left, being the highest in the RLL field with 41 lesions(49.4%), the lowest inthe LLL field with 3 lesions(3.6%). 4. In observing the distribution of the 162 lymphnodal lesions, there are 95lesions(58.6%) in the right and 67 lesions(41.4%) in the left, involving hilar nodes with 150 lesions(92.6%) andmediastinal nodes with 12 lesions(7.4%). The incidence of unilateral involvement is 13 cases (11.3%) and bilateral79 cases (68.7%). 5. Among the total 245 lesions, 141 lesions(57.9%) are smaller than rice in size, 120lesions(49.0%) are amophous in shape and 186 lesions(75.9%) are mainly calcific in density. According to theincrease of age, count and detection rate of the lesion on the chest film are increased. 6. Tuberculin testsshowed 26.1% negative rate in 115 tuberculous cases, and 51% positive rate in 406 negative chest cases.

Ultrasonographic and radiographic findings in 72 cases of pelvic masses which have been provedhistopathologically were analyzed. The results were as follows; 1. Among 72 cases, 28 cases were uterine massesand 44 cases were adnexal masses. 2. Pathologic accuracies of ultrasonographic diagnosis were 64.3% in uterinemasses, 70.5% in adnexal masses, and 68.1% in all pelvic masses. 3. Plain or IVP findings were not specific indiagnosis and showed secondary mass effects or functional disturbances. 4. Because of its high accuracy ofpathologic diagnosis and safety, ultrasonography can be regared as the most valuable and preferential study. Butin cases of cystic myomas, endometrioses, cystic missed abortions and huge masses, the accurate diagnoses weredifficult.

PURPOSE: The purpose of this study was to identify errors in statistical descriptions in articles published in the journal of Korean Radiological Society and to suggest guidelines for the reduction of such errors. MATERIALS AND METHODS: In order to investigate statistical errors, 139 of the 514 original articles published between July 1994 were analysed. To assess the validity of statistical descriptions, five items were evaluated. The five items included descriptions of basic data, statistical tests and their results, tables, articles which had presented two or more statistical methods or results, and the Chi-square test. RESULTS: The percentages of correct descriptions of basic data, statistical tests and their results, tables, articles which had presented two or more statistical methods or results, and the Chi-square test were 86.3%, 74.8%, 24.4%, 76.7% and 79.4%, respectively. In 50 of 139 articles (36.0%), statistical descriptions were correct. CONCLUSION: More than half of the articles assessed contained statistical errors; inaccuracies of this kind might raise doubts about the objective validity of an article and the authors should there fore be careful when performing a study which needs statistical descriptions.

PURPOSE: To determine the enhancing patterns of hepatocellular carcinoma(HCC) and the difference of enhancing patterns according to the tumor size, using spiral CT. MATERIALS & METHODS: We reviewed 213 lesions in 76patients who had been clinically or histopathologically diagnosed as HCC sufferer. The tumors were divided into three groups, according to size(&3 cm, 3-5cm and >5 cm). The enhancing patterns of tumor and capsule in the earlyand delayed phase were analysed. The enhancing patterns of the tumor were divided into five types(high, peripheralhigh, mixed, iso and low attenuation) in the early phase and four types(central high, mixed, iso, and low attenuation) in the delayed phase. The enhancing patterns of the capsule were divided into three types such asiso, low and high attenuation. RESULTS: High attenuating lesions in the early phase were as follows : below 3cm 72% ; 3-5cm., 60% ; above 5cm., 49%. Mixed attenuating lesions in the early phase were as follows : below 3cm., 1%; 3-5cm., 22% ; above 5cm., 36%. Thus, most HCCs were high attenuation type in the early phase, but as the tumorbecame larger, less high attenuation and more mixed attenuation was demonstrated(p<0.01). There was no difference of enhancing patterns according to the tumor size in peripheral high, iso and low-attenuating lesions. In the delayed phase most of the hepatomas appeared as totally hypodense lesions. For capsules, the results were as follows : below 3cm., 20% ; 3-5cm.,58% ; above 5cm., 73%. As the tumors became larger, more capsules were demonstrated(p <0.01). The capsules were visualized as iso or low attenuating rim in the early phase and high attenuating rim in the delayed phase. CONCLUSIONS: To determine the enhancing patterns of HCC using spiral CT is considered to be helpful in the diagnosis of HCC.

BACKGROUND: Fascioliasis is a zoonotic helminthiasis by fasciola species and is occasionally complicated by liver abscess, and the treatment of choice is oral bithionol, which is not available in Korea. Most clinical reports showed that praziquantel given at usual dosage (75 mg/kg for 1day) failed to cure Fasciola hepatica infections, however, it has not been investigated whether long-term praziquantel (70 mg/kg/d for 7 days) would be effective. We evaluated the effectiveness of long term praziquantel therapy in patients with Fasiola liver abscess. METHOD: Three patients who were diagnosed as liver abscess by F. hepatica were included in the current study. The diagnostic criteria for inclusion were 1) eosinophilia, 2) positive serologic test for F. hepatica antigen, 3) characteristic findings on CT scan and 4) demonstration of aggregates of eosinophils on ultrasonography-guided aspirates of the abscess. Praziquantel was given orally to patients at the daily dose of 70-84mg/kg for 7 days. The effectiveness was assessed by the normalization of eosinophil count at the end of 3 months and the disappearance of abscess cavity on ultrasonography or CT scan one year after treatment. RESULTS: Blood eosinophil count decreased less than 500/mm3 in all patients within 2 to 3 months. The liver abscesses reduced in size by 90% in 5 months in one patient and disappeared within a year in two patients. No major adverse effects were observed. CONCLUSION: We conclude that 7-day praziquantel therapy may be effective and safe in the treatment of liver abscess caused by F. hepatica.

Background/Aims: A quick and accurate diagnosis of Helicobacter pylori (H. pylori) infections is vital for effectively managing many upper gastrointestinal tract diseases. Many diagnostic methods have been developed for rapid and accurate diagnosis, including invasive and non-invasive methods, but each tool has some limitations. Among the invasive diagnostic methods, the rapid urease test (RUT) is a relatively time-saving and accurate method, but a variation in the reaction time range causes inconvenience and inefficiency in the clinical field. This study developed a liquid-type medium, Helicotest ® , to enable faster detection. This study examined the reaction time of a new liquid-type RUT kit with other commercial kits. Methods: Two H. pylori strains were cultured (H. pylori ATCC 700392 and 43504), and the urease activity of H. pylori was measured using a urease activity assay kit (MAK120, Sigma Aldrich). Four RUT kits were used to compare the time of H. pylori detection, including Helicotest ® (Won Medical, Bucheon, Korea), Hp kit (Chong Kun Dang, Seoul, Korea), CLO kit (Halyard, Alpharetta, GA, USA), and ASAN Helicobacter Test ® (ASAN, Seoul, Korea). Results: The detection of H. pylori was possible in bacterial amounts less than 10 μL. The color change was detected from five minutes with bacterial densities of 5 μL and 10 μL for both strains, whereas 30 minutes and one hour were required for 0.5 μL and a 1 μL bacterial density of ATCC 43504 and 700392 strains, respectively. Conclusions Compared to other RUT kits, Helicotest ® showed the fastest reaction. Therefore, faster diagnosis in clinical practice is expected.

PURPOSE: To analyse the long-term survival rate after transcatheter arterial chemoembolization (TACE) of hepatocellular carcinoma and to determine prognostic factors. MATERIALS AND METHODS: In 1067 hepatocellularcarcinoma patients who had undergone TACE, of long-term survival rate and prognostic factors were retrospecfively analysed. Chemoembolization was accomplished by hepatic arterial infusion of a mixture of Lipiodol and Adriamycin(51%) or by Gelfoam embolization after infusion of the Lipiodol mixture(49%). The survival rate was calculated by the Kaplan-Meier method and multivariate analysis using the weibull model was applied to determine which prognostic factors were statistically significant. RESULTS: Among the 1067 patients, survival rates were asfollows : one-year, 60.6% ; two-year 42.3% ; three-year, 29.1% ; four-year, 23.7% ; and five-year, 14.7 %. The oneyear survival rate and median survival period of 432 patients with tumors 5cm in diameter or smaller were 77.7%and 33 months respectively, significantly higher than those of patients with larger tumors for whom the corresponding figures were 44.8% and 11 months. Other significant prognostic factors(p<0.0001) shown bymultivariate analysis included type of tumor, portal vein invasion and child-pugh classification. CONCLUSION: Theone-year survival rate agter chemoembolization in 1067 patients with hepatocellular carcinoma was 60.6%. The significant prognostic factors were size and type of the tumor, portal vein invasion, and Child-Pugh classification.

PURPOSE: To transmit DICOM data to a personal computer in the hospital without PACS, and estimate theusefulness of digital image management and its convenience for physicians through transmitted file size,transmission time and quality of transmitted images. MATERIALS AND METHODS: The raw data of three brain MRI andlumbar spine MRI were transmitted from an MR system to a personal computer via Ethernet TCP/IP connection. Thefile size and transmission time of transmitted images were measured according to the matrix number. Threeboard-certified radiologists compared the image quality of the transmitted and scanned images. RESULTS: Thetransmission of DICOM data to the personal computer was successful and the transmitted images and their headerinformation were displayed by various personal computer-based DICOM viewing programs. The file size andtransmission time of the 256 and 512 matrix images were 136 Kbyte, 2.17 seconds/slice and 520 Kbyte, 4.37seconds/slice, respectively. All radiologists regarded the transmitted brain MRI images as superior. Oneradiologist considered the transmitted lumbar spine MRI images superior, while others decided that the quality oftransmitted and scanned images was the same. CONCLUSION: The transmission of DICOM format image data to apersonal computer through an appropriate DICOM receiving program is useful for managing digital images andconvenient for physicians in the hospital without PACS.
