We obtained sixty normal chest postero-anterior(PA) radiographs with high kilovoltage technique(90-100kVp), 10 radiographs from the consecutive normal persons in each decade from twenties to seventies to analyze normal course and appearance of azygoesophageal recess (AER) line. CT scans from sixty consecutive normal persons were correlated with the radiographs to see how the line is formed and what structure the line abuts. In 20 patients with a lesion in AER area (10 with subcarinal lymphadenopathy of various size, five with left atrial enlargement, three with lesions in the esophagus, and two with dilated azygos vein), radiographic and CT correlation was done with main attention to the pattern of displacement of the azygoesophageal line. In normal chest PA radiographs, AER was shown as a straight line in young adults. As age increased, it was seen as a smooth arc with convexity to the left. Sigmoid shape with midline cross was noted in anaged person. At the level of the righ main bronchus on CT, AER was noted along the right lateral aspect to the vertebral margin in young adually. It extended medially as age increased. Caudally the recess extended more medially. The azygos vein usually bordered the recess. The esophagus or mediastinal fat sometimes bordered the recess in caudal level. In normal persons, the recess appeared deeper on plain radiographs than on CT. On plain radiographs, there were no changes in contour of AER with subcarinal lymphadenopathy of less than 2.5cm in diameter. With left atrial enlargement, obliteration of the line was noted at T8-10 level. Focal right sided bulging of the line was noted with esophageal cancer. Dilatation of azygos vein caused the line to appear with right sided displacement. In conclusion, AER line can be delineated with various features on radiographs with high KVP technique, depending on the age of normal persons and the formation of the line can be explained with CT. Displacement and change in the contour of the line can be seen with various mediastinal diseases.

Purpose: To evaluate clinical outcome after documentation of pancreatic pseudocyst by computed tomography (CT). Methods: The clinical course of 18 patients with pancreatic pseudocysts documented by computed tomography (CT) were retrospectively reviewed. History, physical examination, laboratory findings and CT finding were analyzed between operated and non -operated group of pancreatic pseudocysts. Result: There are 20 pancreatic pseudocysts in 18 patients with 16 males and two females (mean age: 45). There is no significant difference between operated and non- operated group in clinical symptoms and laboratory findings. On CT study, there are six cases of intrapancreatic pseudocysts and four cases of extrapancreatic pseudocysts in operated group. The mean diameter of pancreatic pseudocyst is 10.4 cm. In 10 pseudocysts of non-operated group, there are four case of intrapancreatic pseudocysts and six cases of extrapancreatic pseudocysts. The mean diameter of pancreatic pseudocyst is 5.4cm. There are approximately twice in diameter of the pseudocysts between operated and non-operated group (p < 0.05). Conclusion: CT is useful in the guiding of pancreatic pseudocyst management.

In order to assess the value of plain chest radiograh in diagnosing traumatic diaphragmatic rupture due to blunt trauma, we retrospectively reviewed preoperative chest radiograph performed in 25 patients with surgically proven diaphragmatic rupture. The mechanism of injury included traffic accident (passenger:13, pedestrian:11) and fall from height (one case). Traumatic rupture of left and righht hemidiaphragm was 72% (18/25) and 28% (7/25) respectively. 11 cases were diagnostic of traumatic diaphramatic rupture (TDR) on plain chest radiograph as elevated hemidiaphragm with air-containing viscera or obscuration of hemidiaphragem. 4 cases were highly suggestive of TDR as elevated hemidiaphragm without air-containing viscera. Therefore the sensitivity of plain chest radiograph in diagnosing TDR was 60%. Injury of abdominal viscera was combined in 14 cases. Plain chest radiograph obtained at admission & repeated soon after were valuable the diagnosis of TDR.

누두흉은 전흉벽에 생기는 가장 흔한 선천성 기형이다.누두흉은 흉골이 함몰되어 오목 가슴을 만든다.흉골 함몰의 정도와 부위,관련된 흉골의 경사짐과 늑골연골의 심한 볼록함으로 인해 함몰 혹은 돌출의 다양한 변형을 보인다.가장 흔하게 동반되는 질환은 Poland 증후군, Marfan 증후군,측만증 등이다. Pectus excavatum in which the sternum is depressed and the anterior chest wall is concave in shape, is the most common congenital deformity to affect this region of the body. Various deformities involving depression or protrusion are caused by the degree and location of the sternal depression, and associated deformities such as a tilted sternum and anterior convexity of costal cartilages may occur. The most common associated disorders are Poland syndrome, Marfan syndrome and scoliosis.

초음파검사에의한 만성활동성간염과 지방간의 감별점은 명확히 정립된 것이 없다. 본연구자들은 상기의 만성활동성간염과 지방간의 감별점을 초음파검사에 의해 찾아보고자 본연구를 시행하였다. 저자들은 간실질의 에코의 정도와 간문맥의 벽의 불명확정도를 분석하였다. 간의 에코의 정도는 우측신장의 피질과 비교하여 그정도를 분류하였다. 간문맥의 불명확정도를 분류하였으며 가장 않보일때를 그레이드 3으로 정하였다. 정상소견 13례를 포함하여 11례의 지방간과 32례의 만성활동성간염의 초음파필림을 2명의 방사선과전문의가 병리적진단에 대한 정보없이 판독하였다. 지방간에 있어서는 간실질의 에코는 그레이드 Ⅱ가 6례, 그레이드 Ⅲ이 5례였다. 문맥의 불명확정도는 전례에서 그레이드 Ⅲ이었다. 만성활동성간염에서는 간실질의 에코는 그레이드 Ⅰ이 29례, 그레이드 Ⅱ가 2례, 그레이드 Ⅲ이 1례였다. 간문맥의 불명확정도는 그레이드 Ⅱ가 18례, 그레이드 Ⅲ가 14례였다. 초음파소견에 의한 진단의 평균 정확도는 64%였다. 평균 예민도는 60%, 평균 특이도는 77%였다. 본연구의 결과는 두질환을 감별하는데 통계적으로 유의하였다 (p=.0458).

Differentiation between acute and old fractures in the thoracic and lumbar spine is often difficult. We have evaluated the intraobserver agreement and interobserver variability of interpretations. We have prepared 50 cases from 40 patients with thoracic or lumbar spine fracture for evaluation. At first, two radiologist interpreted each of the 50 cases. only by using plain roentgenograms. Then, they interpreted the cases again using also spine CT. HRI. bone scintigrams and follow-up roentgenograms. Intraobserver agreement was found to be 78% in Doctor A, and 76% in Doctor B, Interobserver agreement was only 62% at first. It was 88, when they used CT, MRI, bone scintigrams and follow-up roentgenograms. It was not easy to differentiate the old fractures from acute one only by plain roentgenograms. Differentiation was more difficult. when the patient was female or over 55 years old Plain roentgenography in hyperextension posture seems to be a simple but useful method for the diagnosis of the acute fracture. MRI was more valuable than CT or bone scintigraphy to differentiate the old fractures from the acute ones.
