2.Abnormalities of IV!ucosal Folds of the Small Intestine: a Guide in Interpretation of Small Bowel Series.
Journal of the Korean Radiological Society 1994;31(5):925-932
Normal small intestinal folds are less than 2mm in thickness and criss-cross in appearance. Many diseases of the small interstine produce an abnormality in mucosal folds, namely thickening and parallel (perpendiulcer to the bowel lumen) arrangement of folds, nodularity, destruction, and ulcer. Diseases causing submucosal edema produce regular smooth thickening whereas diseases producing submucosal hemorrhage produce regular spiky thickening. Inflammatory bowel diseases and lymphoma produce irregular (in width, or distorted or 'bent at peculiar angles to the bowel lumen) thickening nodularity of the mucosa. Severe inflammatory processes as well as malignant tumors produce mucosal destruction and ulcer. Proposed here is an approach to narrow the category of disease processes based on mucosal fold abnormality. This approach with sufficient clinical history is invaluable in the interpretation of small bowel series.

3.Effective lecture slides
Journal of the Korean Radiological Society 1986;22(4):641-645
Lawyers, with their constant opportunity for parctive, show a talent for public oratory that few dictors canequal. However, the physician, despite his more modest and hesitant delivery, has one great advantage over themost experienced lawyer. He is allowed to use slides. Slides of good quality conceal defects in oratory and theymake for a confident speaker and a contented audience. By contrast smudged, complicated or ill-prepared slides maydraw attention to minor defects in delivery and make the audience inattentive.

5.An experimental study on vascular changes in renal biopsy injury
Journal of the Korean Radiological Society 1981;17(3):381-391
An experimental study on the vascular alternations of the kidney following biopsy procedure was carried out in 47 kidneys from 28 rabbits to clarify their nature and frequency by renal arteriography and microangiography together with histopathologic investigation. Renal arteriography and microangiography were perforemd immediately 2 days, 1 week, and 2 weeks after percutaneous biopsy and the findings were correlated with histological nature. The results are summerized as follows; 1. Important biopsy injuries verified by renal arteriography and microangiography were arterial spasm, perfusion defect, arteriovenous fistula, injury to vasa recta and renaltubules, intrarenal and extrarenal extravasation of contrast media, and arterial obstruction, in order of frequency. 2. Artierial spasm observed in majority of the cases were relieved during the period of 2 weeks. 3. Detectability of perfusion defect was 57% and 72% by angiography and microangiography, respectively, and this perfusion defect seemed to be mostly caused by renal infarction due to vascular injury, such as arteriovenousfistula, arterial obstruction and other vascular injuries. 4. Arteriovenous fistula was detected in 28% byangiography and 50% by microangiography. Many of the arteriovenous fistula appeared to be closed spontaneously within a week. Above findings suggest that renal biopsy procedure results in various degree of vascular injuries with their sequential modification, and that microangiography is assumed the most effective approach in analysisof biopsy injuries such as small arteriovenous fistula, perfusion defect, injury to vasa recta and renal tubules, overcoming the limitation of traditional angiography.

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

The most common causes of conjugated hyperbilirubinemia after the first or second week of life are neonatal hepatitis and biliary atresia. Since these entities represent variable expressions of same pathologic process and have similar clinical, biochemical, and histologic features, differential diagnosis is extremely difficult. We prospectively studied 28 jaundiced infants by sonography and hepatobiliary scintigraphy. Final diagnoses included 12 biliary atresia and 16 neonatal hepatitis. Visualization of a normal-sized common bile duct or gallbladder was compatible with the diagnosis of neonatal hepatitis. Non-visualized or atrophic gallbladder no sonography coupled with non-visualization of bowel activity on scintigraphy was highly suggestive of biliary atresia. We believe that sonography plays valuable role in the initial evaluation of the infants with persistent neonatal jaundice. The combined use of sonography and hepatobiliary scintigraphy provides the most valuable in formation in suspected biliary atresia for prompt surgical treatment.
