ABSTRACT
DSA(Digital Subtractin Angiography) is a valuable diagnostic imaging method in many clinical fields, includingranal-related conditons. Sixty four renal DSA examinations were performed in 59 patients with renal-relateddiseases from Jan. 1984 to Dec. 1985. Summary of these were as follows: 1. Intraarterial (IA)-DSA is performed in6 cases, intravenous(IV)-DSA in 58 cases. In 58 Examinations of IV-DSA, diagnostic image quality is obtained in 51cases(88%). 2. In investigations of a possible renovascular etiology of hypertension, IV-DSA,is a safe, sensitiveand accurate method. On screening for evaluation of renovascular hypertension, RSP should be replaced with IV-DSA,because IV-DSA is moe sensitive and accurate and can detect not only anatomic change of renal arttery but alsofunctional hemodynamic change. 3. IV-DSA is valuable in diseases with morphologic changes of vessels. Incharacterization of a known renal mass, and evaluation of hematuria, suspected aneurym and renal trauma, IV-DSA isvery useful diagnostic imaging modality. 4. In evaluation of potential renal donors, IV-DSA is an accurate andsafe method with 82.4% of accuracy. IV-DSA also is useful in follow-up of allograft recipients. 5. Ininvestigation of diabetic nephropathy, glomerulonephritis, pyelonephritis, IV-DSA is little helpful. 6. Theadvantages of DSA are well known, particularly post-procedure process using computer programs is helpful forobtaining informations of hemodynamic change or time-sequence-curve of density etc. More technical improvementwith this modality is required for improvement of the image quality and resolution. And more accumulation ofclinical experience is required in order to increase the diagnostic accuracy.

As a adjuvant, 99m Tc-IDA complex cholescintigraphy has been used to differentiate the causes of jaundice,hepatocellular jaundice from the obstructive jaundice. So we conducted the retrospective study from the 41 casesof cholescintigraphy from the Mar, 83 to Sept. 84 at the Dept. of radiology in the Sonnchyunhyang university todetermine the etiology and differential points in the diagnosing the Jaundice. The following results wereobtainend; 1. As a 1st-ordered parameter, the leading edge hepatic parenchymal transit time was very significant in differentiating the causes of jaundice, among the hepatocellular jaundice, obstructive jaundice due to tumor,and obstructive jaundice due to cholelithiasis. (P0.01 by t-test) 3. The difference in hepatic clearance between the biliary obstruction dueto tumor and that of the cholelithiasis, was not significant. (P>0.05 by X2-test) 4. The difference in bile ductdilatation among the hepatocellular jaundice obstructive jaundice due to tumor, and obstructive jaundice due tocholelithiasis, was singnificant in differentiating the causes of jaundice. (P<0.05 by X2-test) 5. Intrahepaticstone showed scintigraphic pooling with partial stasis. 6. Cholescintigraphy was useful to differentiated the Rotor's syndrome from the Dubin-Johnson syndrome, supplying the additional criteria.

The UGI studies had been performed to 238 patients below the age of 15 years during the period from Jan. 1979to Jul. 1983 in SCH hospital. The results are as follows; 1. Among 238 cases, 48 cases revealed peptic ulcers ofstomach or duodenum (20.2%). The ulcer was in 31/37 cases of male patients(22.6%), and in 17/101 cases of female(16.8). Below the age of 5 years, ulcer was noted in 9 cases among 61 cases (14.8%), whereas above 5 years, in 39cases among 177 patients (22.0%). 2. In the age group below 5 years, mostly the objective symptoms were discovered(8/9), but above 5 years, complained of subjective symtoms (30/39). 3. The predominant site of peptic ulcer wasgastric antrum in the age group below 5 years (7/9), whereas duodenal bulb above 5 years(33/43). 4. Gastric antrumor duodenal bulb deformity was revealed in 13 cases and most of them were in the age group above 5 years. 5. Alllesion so peptic ulcers in this study were benign in nature. 6. In follow up study after 1 or 2 months, ulcer wasdecreased in size strikingly(9/11).

Bone scan using 99m Tc-MDP is the most accurate and reliable method for the early detection of fracture, andgive the most accurate in formation about the healing process of fractured bone. Recent days, the medicolegalproblem about the injured time is frequently provoked in vertebral fracture patient by trauma. The authorsanalyzed the bone scan of vertebral fracture patients from March to Dec. 1983. The authors obtained results asfollows: 1. The minimum time for a fracture to return to normal on a bone scan was 4 month in cervical spine. 2.It was 12 month in thoracic spine. 3. It was 6 month in lumbar spine. 4. Surrounding soft tissue injury was healedwithin 10 days after trauma in our cases. 5. Focal hot uptake is persisted in case of callus deposition on plainfilm, although very small in amount. 6. Healing time is delayed in case of severely compressed vertebral body,belowed the half than normal height. 7. With bone scan it is possible to differentiate the fresh fracture from oldhealed, impossible by plain film. 8. Healing time is delayed in old age.

The study was undertaken to asses the changes in the size and densities of intracranial hematomas by analyzingthe sequential CT examination of 23 patients ar Soon Chun Hyang College Hospital from July '80 to Aug. '81. Theresuls were as follows; 1. The high densities of hematoma were the cause of hematoma, hematoma locaiton, age andsex of patients, and initial hematoma size. 3. The CT findings that indicate complete absorption of hematomas werenormalization of mass effect, not diappearence of hematoma densities. 4. In intracerebral hematoma, the highdensity of hematoma reduced it's density and mass effect about 4-6 weeks duration. 5. In subdural hematoma, about7 weeks after head trauma, the CT findings were normalized.
