Most pseudoaneurysms of splanchnic arteries are caused by pancreatitis, biopsies or operative trauma, In the cases of pseudoaneurysms by pancreatitis, the splenic arbeiy is the most common site of bleeding, Complication of splenic artery pseudoaneurysms is the rupture into the peritoneal cavity and hemorrhage by the erosion of adjacent structure, In this case, we report the CT findings and angiographic findings of lower gastrointestinal hemorrhage by erosion into colon of the splenic artery pseudoaneurysm.

The clinical applications of cardiac MRI for defining viability of myocardium, congenital heart diseases, and various other heart diseases are evolving due to the advantage of the technique's excellent spatial resolution, Its large field of view, unlimited imaging planes, CINE imaging and delayed enhancement with contrast enable the depiction of complex lesions, abnormal movement of chamber, myocardial ischemia and infarction. Recently, guidelines for when this technique should be employed in clinical practice have revised on 2004. Therefore the aim of this article (from a Consensus Panel by the Working Group on CMR of the European Society of Cardiology and the Society for Cardiovascular Magnetic Resonance) is to update these guidelines tor cardiovascular radiologist, cardiologist, and cardiac surgeon at Chosun University Hospital.

An application of the multi-detector computed tomography (MDCT) for cardiac imaging is the non-invasive CT angiographic assessment of the cardiac morphology and of the major coronary arteries. The most important application is for the non-invasive diagnosis of coronary artery disease and this includes assessment of coronary artery anomaly and stenosis, evaluation of non-calcified atherosclerotic plaque, and follow-up examinations after stent deployment and bypass surgery. We illustrate a variety of diseases of the coronay artery by using MDCT. These will facilitate understanding of MDCT features of coronary artery lesions.

Purpose: The goals of this study are to evaluate and to analyze radiologic findings of Fitz-Hugh-Curtis syndrome (FHCS). Materials and Methods: Eight women with right upper abdominal pain who were radiologically diagnosed with FHCS were included. Abdominal ultrasonography (US) and dynamic computed tomography (CT) of the abdomen with triphasic (arterial, Portal, and delayed phases) scans were performed in all patients. We reviewed patterns and sites of enhancement and combined another radiologic findings. Follow-up CT was available in 1 patient. Results: On enhanced CT, hepatic and splenic capsular enhancement was identified in 8 and 7 patients, respectively. Hepatic capsular enhancement on the early phase, which was detected in all patients, disappeared after treatment (n=1). No adhesive band or fluid collection around the liver was evident. No enhancement of the "bare area" of the liver and spleen was seen. Combined radiological abnormalities in abdomen and pelvis are hepatic hemangioma (n=1), myoma and polyP (n=1), Pelvic inflammation (n=4), and ovarian cyst (n=4). Abnormalities detected by US are hepatic hemangioma (n=1), Peritonitis (n=1), and ovarian cyst (n=2). Conclusion: Hepatic and splenic capsular enhancement on abdominal enhanced CT may be characteristic of FHCS. Enhanced CT may be a useful and noninvasive modality to help a di- agnosis of FHCS, especially in young women with right upper abdominal pain without significant findings on abdominal US and gastrointestinal endoscopy.

Purpose: The goal of this study is to evaluate the intel-observer agreement in diagnosis of pulmonary embolism with multidetector row computed tomography. Materials and Methods: 62 patients were identified retrospectively from 76 consecutive patients who were diagnosed with a pulmonary embolism either clinically or with chest multidetector-row CT (MDCT). Among 76 patients, 14 patients were excluded because there was no evidence of a pulmonary embolism or there was different interpretation of the pulmonary embolism comparing with previous interpretation between radiologists. The radiological data for the patients were assessed by two thoracic radiologists who interpreted the chest MDCT in terms of the diagnosis of a pulmonary embolism and the location of the thrombus independently. A clinical diagnosis was scored by the basis of the approximate prevalence of pulmonary embolism ("Rules for predicting the probability of embolism" by Wells et al.). Patients were considered low probability if the score was <2.0, moderate of the score was 2.0 to 6.0 and high if the score was over 6.0. Results: The accordance of the radiologists was 96% in the main, 84% in the lobar, 90.2% in the segmental, and 94% in the sub-segmental pulmonary arteries. After excluding the negative interpretation from both radiologists, their agreement was 78.3% (κ: 0.85) in the main, 59.8% (κ: 0.66) in the lobar, 53.5% (κ: 0.64) in the segmental, and 41.6% (κ: 0.54) in the sub-segmental pulmonary arteries. The mean score of the patients according to the Wells method was 3.62 ± 0.40 (0-9) and patients with low, moderate, and high probability were 15, 40, and 7 respectively. Conclusion: Chest MDCT has been recently applied to patients suspected of having a pulmonary embolism, It was found that CT is a rapid test for diagnosing a thrombus, and there was reliable accordance between the observers from the area of the large pulmonary arteries. However, there was a lack of agreement between the observers in diagnosing thrombi located distal to the sub-segmental arteries.

In order to investigate the factors influencing the chronic obstructive pulmonary disease (COPD), especially for the relationship between gastroesophageal reflux disease(GERD) and COPD, a case-control study was conducted in chonnam area. Data were obtained from hospital records and interview survey from Jan. to Dec. 1991. Final 64 cases with COPD(case group) were compared with 83 cases of normal lung(control group 1) and 45 cases of non-COPD lung disease (control group 2) The results were as follows. 1. Smoking status, history of adulthood pulmonary infection and frequent history of URI, socioeconomic status and GERD were significantly different between COPD group and control group 1. 2. Drinking status, physical height of the subjects and GERD were significantly different between COPD group and control group 2. 3. If control group 1 was used, odds ratio of GERD and COPD was 5.68(95% confidence interval, 95% CI: 2.59-12.45) and 4.81(95% CI: 1.89-10.53) when adjusted by age and smoking status. 4. If contol group 2 was used, odds ratio of GERD and COPD was 4.22(95% CI: 1.69-10.56) and 4.59(95% CI: 1.64-12.86) when adjusted by alcohol and adulthood respiratory infection status. 5. This results suggested that GERD might play a causative role in the development of COPD.
