The purpose of this study is to analyze the medical care utilization behavior of patients to whom treatment (surgery) is recommended after they are diagnosed with abnormal findings on health screening and factors affecting the selection of the medical institute for treatment. The data was collected from 291 patients who need treatment or surgery, according to the abnormal findings on the additional examination such as cardiac CT, brain MRI, Gastroscopy and Colonoscopy since four diseases are suspected among of 2,752 people who receive health screening. The results are as follows. First, the most common disease of patients who have abnormal findings by the diagnosis through the results of first testing is colon disease based on through the additional examination. The most common disease of patients who will get treatment (surgery) based on final diagnosis by a doctor who determines the result of health screening on the basis of diagnosis from the first testing is cardiovascular disease. Second, in terms of diseases, patients with cardiovascular disease select the medical institute where they get the health screenings as a place for treatment. Patients with cerebrovascular disease select another medical institute for treatment. Finally, the affective factors of selectivity treatment facility on health screening satisfaction were human, facility, health screening and revisit factors.

폐 격리증이 없는 정상적인 폐에 체 혈관이 이상 기시하는 것은 매우 드문 질환이다. 저자들은 반복적인 하기도 감염을 보이는 영아에서 선천성 심장질환의 상태가 본 하기도 감염을 나타낼 정도로 심하지 않음을 이상히 여겨 컴퓨터 단층 촬영을 시행하였다. 그 결과 폐 격리증이 없는 폐의 이상 체 동맥 기시가 우측 폐하 엽에 존재함과 동시에 우측 하엽 폐동맥이 없는 사실을 확인하게 되었다. 어린 나이에 이 같은 선천성 질환의 조합은 이전에 보고 된 바가 없는 매우 드문 질환으로 생각된다.

A 4-month-old, female Maltese dog was referred with continuous heart murmur. Patent ductus arteriosus was diagnosed via radiography and echocardiography. The patient was untreated because of client's refusal. After 13 months, the dog was referred again with seizure and salivation. Laboratory examination revealed increased liver enzymes, hyperammonemia and decreased total cholesterol and total protein. Microhepatica was identified on abdominal radiography. CT angiography showed a shunt vessel that originated from the portal trunk to the prehepatic caudal vena cava and patent ductus arteriosus connecting proximal descending aorta with the main pulmonary artery. No portal vasculature toward liver is observed after shunt vessel. The patient was diagnosed as concurrent patent ductus arteriosus and congenital extrahepatic portosystemic shunt with suspected portal vein aplasia. In human, cardiac malformations are frequently observed in patients with congenital extrahepatic portosystemic shunt with portal vein aplasia. This report described concurrent patent ductus arteriosus and congenital extrahepatic portosystemic shunt with suspected portal vein aplasia in a dog.

DiGeorge syndrome is a disorder caused by microdeletion in chromosome 22q11.2 with various abnormalities including cardiac anomaly, facial dysmorphism, thymic and parathyroid hypoplasia, cleft palate and immune dysfunction. The frequency of hypocalcemia caused by hypoparathyroidism is known to be approximately 60% of DiGeorge syndrome. It is known that the disorder mostly occurs in the neonatal period and the symptoms are improved afterwards. Herein we report a case of DiGeorge syndrome only accompanied by hypocalcemia caused by hypoparathyroidism without other abnormalities. She was first diagnosed only at the age of 22 with basal ganglia calcification that had been discovered in brain CT (Computed tomography).

Congenital diverticula of the cardiac ventricle have been reported as arising either from the left ventricle or, rarely from both ventricles. A diverticulum arising from the right ventricle alone is very rare. Furthermore the diverticulum associated with double chambered right ventricle was extremely rare. We experienced a 62 years old female of double chambered right ventricle combined with congenital right ventricular true diverticulum. She had complained intermittent chest pain and mild dyspnea on exertion during 8 months. The chest X-ray and chest CT showed protruded abnormal density at anterolateral side of right ventricular outflow tract. Preoperative angiography demonstrated a double chambered right ventricle and a right ventricular diverticulum. In operative finding, there was found a anomalous muscle band, dividing the right ventricle into an inflow and outflow portion, and a 5x6cm sized right ventricular diverticulum arised from conus region with a stenotic orifice of 1.5cm in diameter. The diverticulum was open toward the infundibulum, and its orifice was approximately 1cm in diameter. On treatment, the diverticulum orifice was closed directly and the abnormal muscle band was resected in order to widen the right ventricular outflow tract. The postoperative result was satisfactory and good without specific complications.

Objective: To describe the radiologic findings of migrating lobar atelectasis of the right lung. Materials and Methods: Chest radiographs (n = 6) and CT scans (n = 5) of six patients with migrating lobar atelectasis of the right lung were analyzed retrospectively. The underlying diseases associated with lobar atelectasis were bronchogenic carcinoma (n = 4), bronchial tuberculosis (n = 1), and tracheobronchial amyloidosis (n = 1). Results: Atelectasis involved the right upper lobe (RUL) (n = 3) and both the RUL and right middle lobe (RML) (n = 3). On supine anteroposterior radiographs (n = 5) and on an erect posteroanterior radiograph (n = 1), the atelectatic lobe(s) occupied the right upper lung zone, with a wedge shape abutting onto the right mediastinal border. On erect posteroanterior radiographs (n = 6), the heavy atelectatic lobe(s) migrated downward, forming a peri- or infrahilar area of increased opacity and obscuring the right cardiac margin. Erect lateral radiographs (n = 4) showed inferior shift of the anterosuperiorly located atelectatic lobe(s) to the anteroinferior portion of the hemithorax. Conclusion: Atelectatic lobe(s) can move within the hemithorax according to changes in a patient s position. This process involves the RUL or both the RUL and RML.

건강한 정상인의 복부대동맥과 장골동맥 분기관의 다이콤 의료 영상으로부터 구성된 혈관 모델을 대상으로 전산혈류해석을 수행하였다. 본 연구에서는 CT로 촬영한 혈관영상으로부터 단면영상을 읽고 각 단면의 경계 좌표를 매끄럽게 추출하는 프로그램을 개발하여 적응하였다. 해석용 3차원 메쉬 생성과 혈류해석은 상용프로그램을 사용하였다. 해석을 통해 얻어진 압력, 속도 및 유량 분포는 정상인의 생리학적 범위 내에 있었다. 초음파로 측정된 장골동맥 중심부의 심장 수축기 속도는 해석에 비해 20% 정도 작은 값을 보였으며 한 주기 동안 속도 변화의 경향은 유사하였다. 본 연구의 접근방법은 환자 개인의 실제 혈관 형상에 기반한 혈류해석으로서 좁아진 동맥 또는 시술 될 동맥에서의 압력, 속도값, 속도분포에 대한 정보를 제공한다. 이 결과는 의사로 하여금 환자의 혈류역학적 변수의 변화를 파악하게 하여 환자의 상태를 더 잘 이해하고 수술의 필요성을 판단하도록 도움을 줄 수 있으며 나아가 혈관 수술의 기초자료로 사용될 수 있을 것이다. 이 연구는 향후 동맥경화와 밀접히 연관된 혈류역학적 변수의 분포를 혈관 내에 보여줌으로서 동맥경화를 조기 진단하는 프로그램으로 발전할 것으로 기대된다.

Background: To investigate the impact of the breast size, shape, maximum heart depth (MDH), and chest wall hypotenuse (the distance connecting middle point of the sternum and the length of lung draw on the selected transverse CT slice) on the volumetric dose to heart with whole breast irradiation (WBI) of left-sided breast cancer patients. Materials and Methods: Fifty-three patients with left-sided breast cancer undergoing adjuvant intensity-modulated radiotherapy (IMRT) were enrolled in the study. The primary breast size and shape, MHD and DCWH (chest wall hypotenuse) were contoured on radiotherapy (RT) planning CT slices. The dose data of hearts were obtained from the dose-volume histograms (DVHs). Data were analyzed by one-way analysis of variance (ANOVA), Student's t-test and linear regression analysis. Results: Breast size was independent of heart dose, whereas breast shape, MHD and DCWH were correlated with heart dose. The shapes of breasts were divided into four types, as the flap type, hemisphere type, cone type and pendulous type with heart mean dose being $491.8{\pm}234.6cGy$, $752.7{\pm}219.0cGy$, $620.2{\pm}275.7cGy$, and $666.1{\pm}238.0cGy$, respectively. The flap type of breasts shows a strong statistically reduction in heart dose, compared to others (p=0.008 for V30 of heart). DCWH and MHD were found to be the most important parameters correlating with heart dose in WBI. Conclusions: More attention should be paid to the heart dose of non-flap type patients. The MHD was found to be the most important parameter to correlate with heart dose in tangential WBI, closely followed by the DCWH, which could help radiation oncologists and physicsts evaluate heart dose and design RT plan in advance.
