Periampullary carcinomas arise within 2 cm of the major duodenal papilla and comprise carcinomas of the ampulla, distal common bile duct, pancreas, and duodenum. Their clinical features and anatomic locations are similar, as are the therapeutic approaches; however, their long-term outcomes vary. Magnetic resonance (MR) images of 89 pathologically proved periampullary carcinomas (29 ampullary carcinomas, 27 distal common bile duct carcinomas, 21 pancreatic carcinomas, six duodenal carcinomas, and

Summary The antioxidative and anti‐allergic activities of fresh and aged black garlic extracts were investigated. The garlic samples were extracted with 70% ethanol (v/v) and the total phenolic content was measured. The antioxidant capacity of extracts was assessed by determining the scavenging activities on 1,1‐diphenyl‐2‐picrylhydrazyl and hydroxyl radicals, ferricyanide reducing power, ferrous ion‐chelating ability and inhibitory effect on linoleic acid peroxidation. The anti‐allergic activit

PURPOSE: The purpose of this work was to determine the diagnostic accuracy of MRI for the differentiation of mucinous and nonmucinous carcinomas in patients with rectal carcinomas. METHOD: Seventy-six patients with pathologically proven rectal adenocarcinomas were evaluated with MRI. Both T2-weighted fast spin echo and T1-weighted spin echo images were independently reviewed by two radiologists who were blinded for tumor histology. Of the 76 cases, mucin pools were found in 28 (37%), and 16 had

High-resolution pelvic MRI was more accurate than PET/CT for the prediction of regional nodal status. Magnetic resonance imaging had a high sensitivity and PET/CT had a high specificity for N staging in rectal cancer.

MR cholangiography is highly accurate in the detection of CBD stones in all patients, regardless of the grade of risk, and should be considered in patients with a moderate to high risk of CBD stones before cholecystectomy.

PURPOSE: We sought to evaluate the clinical usefulness of CT colonography (CTC) after incomplete conventional colonoscopy (CC) for occlusive colorectal cancer (CRC) according to the tumor location. MATERIALS AND METHODS: Seventy-five patients with occlusive CRC underwent subsequent CTC immediately after incomplete CC. Fifty-nine patients had distal CRC and 16 had proximal colon cancer. Experienced radiologists prospectively analyzed the location, length, and TNM staging of the main tumor. The co

경제적 불평등과 상대적 박탈의 심화가 개인의 정신건강에 미치는 부정적 영향이 심각함에도, 기존의 빈곤과 정신건강 간의 관계에 대한 연구는 주로 사회경제적 지위(SES)만을 빈곤의 지표로 삼아 진행되어 왔다. 본 연구는 보다 포괄적인 빈곤 개념인 사회경제적 박탈이 우울에 미치는 영향을 살펴보고, 이에 대한 연령의 조절효과를 검증하는 것을 목적으로 한다. 이를 위해 한국복지패널 9차년도(2014년)에서 전국 20세 이상 성인 총 13,005명의 자료를 활용하였다. 사회경제적 박탈은 한국복지패널 문항 중 식생활, 주거, 교육, 사회보장, 직업 및 경제상태, 사회적 요건, 건강 및 의료 등 7가지 영역에 대한 22개 문항을 선별한 후 각각에 대한 박탈여부를 측정･합산하여 지수화 하였고, 우울은 CESD-11 척도를 사용하였으며 연령은 연속변수로 처리하였다. 사회경제적 박탈과 우울의 관계 및 연령의 조절효과를 검증하기 위해 중다선형회귀분석을 사용하였다. 분석결과, 사회경제적 박탈과 우울 간

PURPOSE: To evaluate the different signal characteristics of focal hepatic lesions on ferumoxides-enhanced MR imaging, including T1-weighted spoiled gradient recalled echo (GRE) images using different echo times (TE) and T2- and T2*-weighted images. MATERIALS AND METHODS: Ferumoxides-enhanced MR imaging was performed using a 1.5-T system in 46 patients who were referred for evaluation of known or suspected hepatic malignancies. One hundred and seven lesions (42 hepatocellular carcinomas [HCC], 4

An annular pancreas is a rare congenital anomaly in which a portion of the pancreatic tissue surrounds the duodenum. Magnetic resonance cholangiopancreatography (MRCP) is used extensively for evaluating the pancreatobiliary ducts. There have been only few cases in which MRCP clearly demonstrated the types of annular ducts, however. Two cases of an annular pancreas based on a new classification of the morphologic type are reported.

Materials And Methods: Seventy-five patients with occlusive CRC underwent subsequent CTC immediately after incomplete CC. Fifty-nine patients had distal CRC and 16 had proximal colon cancer.

Anticoagulant drugs, like vitamin K antagonists and heparin, have been the mainstay for the treatment and prevention of venous thromboembolic disease for many years. Although effective if appropriately used, traditional anticoagulants have several limitations such as unpredictable pharmacologic and pharmacokinetic responses and various adverse effects including serious bleeding complications. New oral anticoagulants have recently emerged as an alternative because of their rapid onset/offset of a

The holmium-166-chitosan complex seems to be useful as a new painless sclerosing agent for the treatment of renal cysts with no significant complications.

OBJECTIVE: The purpose of this study was to evaluate the usefulness of kinematic MR cholangiopancreatographic (MRCP) images as an aid in predicting the need for intervention in patients with biliary dilatation. SUBJECTS AND METHODS: Fifty patients with suspected pancreaticobiliary disorders were separated into three groups. Group I patients had biliary dilatation with periampullary lesions (n = 16), group II patients had supraampullary obstructive lesions (n = 17), and group III patients had bil
