Percutaneous Transluminal Agioplasty(PTA) is an effective initial treatment modality in renovascular hypertension. For determination of PTA effect, the pulse pressure recording of renal artery is not simple as compared within femoral artery stenosis. We tried to evaluate the PTA effect of renal artery stenosis with tracing the pressure of distal renal artery. We used the cardian catheterization apparatus(VR-12 Honeywell) as a pressure monitor in two cases of focal renal arterial stenosis. The renal artery pressure was doubled after first attempt of ballooning , and the rpressure elevated up to 94 % and 79% of aorta pressure in two cases, respectively, after third attempt. We believe that renal artery pressure monitoring is a good method of determination of PTA effect in renovascular hypertension.

The ultrasonography(US) is one of very important item for abdominal evaluation. Especially for the routine check of the abdomen, the US becomes the essential part of the precedure. Though the abdominal US is simple and easy, its value is very high for detection of various morphological changes of abdominal organs. The study techniques of US, common abdominal abnormalities, standardization of image interpretation, and clinical significance of the lesions, etc, were discussed.

The routine chest roentgenogram is standardized as upright postero-anterior teleroentgenogram with half inspiration, but in impossible cases, such as infants, children and severe illed patients, the supine chest AP view have to be taken. There are many different points between upright chest PA and supine chest AP view. Authors analysed the 51 cases of normal upright chest PA and supine chest AP views which were taken in the same people, same exposure factors and the same tube-film distance of 72 inches. The results were as follows: 1. The width of the mediastinum was wider in the supine chest AP view than the upright chest PA view, 6.60$\pm$1.36cm, respectively. 2. The diameter of right descending pulmonary artery was slightly smaller in the supine chest AP view than the upright chest PA view. The distribution of the pulmonary vasculartures was nearly even in the supine chest AP view. 3. The transverse diameter of the thorax was slightly smaller in supine chest AP view, but the t ansverse diameter of the heart was significantly increased in the supine chest AP view. The transverse diameter of the heart was 12.12$\pm$1.5cm in upright chest PA, and 13.12$\pm$1.63cm in supine chest AP, respectively. 4. The cardiothoracic ratio was markedly increased in supine chest AP than the upright chest PA view. the cardiothloracic ratio of the upright chest PA was 43.72$\pm$3.97%, and in the supine chest AP, it was 48.19$\pm$4.73%. 5. The supine chest AP view of this study is different in tube-film distance from the routine portable films of the chest AP view, and the magnification factors are probably different. Further studies are need.

Among the main components of the Triogy of Fallot, pulmonary stenosis, right ventricular hypertrophy and right to left shunt through the ASD or patent foramen ovale, pulmonary stenosis is the most important factor. Due to the pulmonary stenosis, right ventricular and right atrial pressure are increased and this results in venoarterial shunt across the ASD or patent foramen ovale and in cyanosis. Radiological findings of eight cases of the Trilogy experienced at the Department of Radiology, Seoul National University Hospital, were analysed with their clinical findings. The summerized results were as follows: 1. Male to female ratio was 4 : 4, and the age of the patients was distributed between 6 year and 31 year. The common symptoms and signs of the patients were cyanosis, dyspnea on exertion, phalangeal clubbings and grade III-IV systolic murmur. In most cases, the clinical diagnosis was the Tetralogy of Fallot. 2. The characteristic findings of right heart catheterization were (1) right to left transatrial shunt, (2) increased right ventricular pressure without transventricular shunt, and (3) abrupt decrease of pulmonary arterial pressure. In all eight cases, the right ventricular pressure was elevated more than 100mmHg, and in six cases, the right ventricular pressure was elevated more than systemic blood pressure. 3. In chest PA view, six of eight cases were presented mild cardiomegaly, however in two cases, the cardiothoracic ratio was under 50%. Important chest PA findings were prominent pulmonary conus, decreased pulmonary vascularity and left atrial enlargement. In all cases, the cardiac apex was not elevated. 4. In right heart cardioangiograms, the right ventricular cavity was small except one case, and infundibular hypertrophy of right ventricle was present in all cases. The left lateral view of right heart cardioangiogram was very useful in the evaluation of the infundibular hypertrophy, pulmonary valvular stenosis and poststenotic dilatation of p lmonary artery, Especially the stenosis, thickening and doming of the pulmonary valve was beautifully demonstrated in the left lateral view of right heart cardioangiogram. 5. The right heart cardioangiogram, with right heart catheterization, was essential in diagnosis of the Trilogy of Fallot.

The value of selective celiac and hepatic angno Graphy in the diagnosis of primary hepatoma of the liver has amply been documented in the literatures. The selective angiography is useful not only for the diagnosis of primary hepatoma and its vascular anatomy but also for intraarterial injection of anticancerous durgs. The findings of selective celiac and/or hepatic arteriorgraphy in total 38 cases of confirmed hepatocellular carcinoma of the liver, with their clinical findings, were analysed. The summarized results are as follows: 1. Incidence of hepatoma is more common in male: male to female ratio is 34:4, and the peak age incidence is 5th to 7th decades (73.7%). About twothirds of the all patients had a clinical onset characterized by indefinite abdominal symotomes such as epigastric discomfort, indigestion and palpable mass in right upper quadrant. The laboratory examinations revealed elevation of serum alkaline phosphatase more than 5 Bodansky units in 73.5% of all patien s, and the alphafeto-pretein was positive in 66% of all patients. 2. The simple chest chest PA films revealed metastatic nodules in the lung of 5 cases and esophagograms demonstrated 8 cases of esophageal varices. 3. All 38 cases were hypervascular in the selective angiograms, and the angiographic gross anatomical types were 17 cases of massive type, 11 cases of diffuse type and 10 cases of nodular type. Most constant angiographic findings of the hepatocollular carcinoma was hypervascularity and tumor vessels (100%), and the other important findings were tumor stanings (96%), displacement of intrahepatic arteries (74%), arterioportal shunt (66%), vascular lakes and channel (61%) and encasement of hepatic artery (26%), in orders, The portal vein regurgitation was in 7 cases and the artery-to-hepatic vein shunt with tumor mass in hepatic vein was in one case. 4. In 28 cases of hepatoma patients, the intraarterial injection of 10mg of Mitomycin was done through the catheter after the an iographic studies. 5. The selective hepatic and/or celiac arteriographies are one of excellent diagnostic tool of hepatocellular carinoma and an essential technique for intraarterial injection of anticancerous drugs in hepatoma patients.

The radiological studies are very important in the diagnosis of pericarditis. The clinical and radiological findings of 57 cases of pericarditis which were diagnosed at the Seoul National University Hospital during past seven years from January 1969 to November 1976 are analysed. The diagnosis was based on aspiration of the pericardial fluid with or without air replacement, operation such as pericardiotomy or pericardiectomy and other clinical studies. Performed radiological studies include simple chest PA and lateral, fluoroscopy, pneumo-pericardiography, cardiac scan, echocardiography and angiocardiography. The results are as follows: 1. There is no sex difference of incidence and age distribution is even in all age groups. 2. The tuberculous origin is most common and 42.1% of total 57 cases, and pyogenic, malignant, cardiomyopathy, uremia and trauma are the etiology in decreasing order. The idiopathic pericarditis are 11 cases. 3. The main symptoms were dyspnea(61.4%), ches pain(14.0%), abdominal distension(14.0%) and the physical findings of pericarditis were remote heart sound(59.6%), hepatomegaly(59.6%) and neck vein engorgement(49.1%). 4. Pericardiocentesis was performed in 37 cases and the nature of the effusion was bloody in 51.4%, seroexudate in 29.7% and us in 18.9%. 5. Cardinal findings of pericardial effusion in simple chest PA were cardiomegaly(80.7%), acute cardiophrenic angles(68.4%), pleural effusion(56.1%) and straightening of left cardiac border or narrowing of cardiac waist(49.1%). 6. On the pneumopericardiography, the thickness of the pericardium is not related to the etiology but to the duration of the diseases.
