PURPOSE: To evaluate diagnostic usefulness of ultrasonography(US) in pediatric patient with urinary tract infection. MATERIALS AND METHODS: Fifty-five children with urinary tract infection underwent renal ultrasonography and voiding cystourethrography(VCUG). The imaging findings were analyzed retrospectively. RESULTS: Renal sonograms were normal in 34 of 55 children(62%). Five of 34 patients with normal sonogram had vesicoureteral reflux of grade I to III on VCUG. Renal sonograms were abnormal in 21 of 55 children(38%). Sonographic findings included hydronephrosis, hyperechoic kidney, nephromegaly, atrophic kidney, renal abscess, and duplex ureter. Eleven of 21 patient with abnormal SOhogram had vesicoureteral reflux of grade I to IV on VCUG. CONCLUSION: Ultrasonography is an useful and reliable initial screening examination in the investigation of children with UTI. Unfortunately US is neither sufficiently sensitive nor specific for detecting VUR. VCUG provides confirmative and valuable information about vesicoureteral reflux, and VCUG should be considered as a next modality for UTI. The combined use of sonography and VCUG provides more valuable information in urinary tract infection.

PURPOSE: To verify the value of CT in the diagnosis of cirrhosis, CRL ratio was measured in 225 Koreans who had and evidence of cirrhosis both clinically and radiologically. MATERIALS AND METHODS: The mean value of CRL ratio was 0.68+/-0.21 which was significant difterent from the published value of normal person(0.45+/-0.07). The difference of CRL ratio between men and women and that among different age groups were found to be not statistically signficant. RESULTS: CRL ratio of virus- related group(N:149) was 0.64+/-0.18, whereas that of virus-nonrelated group (N=76) was 0.76+/-0.23. There was a statistically significant difference of CRL ratio between virus-related group and virus-nonrelated group. CRL ratio of hepatoma-related group(N:113) was 0.71+/-0.22 whereas that of heparoma-nonrelated group(N:112) was 0.66+/-0.19. There was no statistically significant difference of CRL ratio between hepatoma-related group and hepatoma-nonrelated group. CONCLUSION: Measurement of CRL ratio by CT is a useful method in assessing cirrhosis of the liver.

Syphilitic involvement of the stomach often takes the appearance of neoplastic conditions. We describe the radiological findings of syphilitic gastritis. A 36-year-old man was diagnosed with gastric cancer by upper GI and CT, but syphilitic gastritis was confirmed by endoscopy and upper GI series performed after penicillin therapy, We report a case of syphilitic gastritis presented as advanced stomach cancer by clinical, endoscopic and radiological study.

Two patients with clinical and biochemical evidences of islet cell hyperfunction underwent percutaneous transhepatic portal and pancreatic vein catheterization and hormone assays. Local step-ups of insulin level in the protal venous system, found in two patients with insulinoma, corresponded to tumor sites at surgery. One patients had single insulinoma and the other had malignant insulinoma and liver metastasis. Percutaneous transhepatic protal and pancreatic vein catheterization with measurement of radioimmunoactive insulin concentration is a safe and reliable method, and may play an important role in the localization of adenoma in patients with hyperinsulinism.
