Evaluation of posttreatment response of hepatocellular carcinoma: comparison of ultrasonography with second-generation ultrasound contrast agent and multidetector CT
Abdominal Imaging - Tập 35 - Trang 447-453 - 2009
We evaluated the ability of one-month follow-up contrast-enhanced ultrasound (CEUS) with second-generation contrast agent in monitoring radio frequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) treatments of hepatocellular carcinoma (HCC). One-hundred forty-eight HCCs were studied using CEUS: 110 nodules were treated with RFA [41/110 RFA were performed using a pretreatment...... hiện toàn bộ
Preoperative evaluation of gastric cancer: value of spiral CT during gastric arteriography (CTGA)
Abdominal Imaging - Tập 26 - Trang 123-130 - 2014
Background: To evaluate the utility of dual-phase spiral computed tomography during gastric arteriography (CTGA) in the preoperative staging of gastric cancers.
Methods: We performed CTGA in 21 patients with pathologically proven gastric cancers. CTGA findings were prospectively analyzed and correlated with surgical and pathologic findings. Dual-phase scans were p...... hiện toàn bộ
Causes of error in gastrointestinal radiology
Abdominal Imaging - Tập 5 - Trang 99-105 - 1980
A study of causes of error on barium enema examinations is reported. There were 144 patients with 189 inflammatory and neoplastic lesions of the large bowel examined endoscopically and with a preceding barium enema. Twelve lesions were not reported radiologically, a false negative error rate of 6.3%. Radiographic errors included 11 polyps and 1 sigmoid carcinoma. Causes for these errors were analy...... hiện toàn bộ
Magnetic resonance imaging of macroscopic intrahepatic portal-hepatic venous shunts
Abdominal Imaging - Tập 16 - Trang 221-224 - 1991
Direct communication between portal branches and the hepatic vein [macroscopic intrahepatic portal-hepatic venous shunt (IPHVS)] is a rare entity. We have recently studied five patients with this condition. Magnetic resonance imaging (MRI) clearly demonstrated in each case the portal-hepatic venous shunt due to “flow void. “ Multiple diffuse shunts were present in one case and a solitary shunt was...... hiện toàn bộ
Enhanced CT for initial localization of active lower gastrointestinal bleeding
Abdominal Imaging - Tập 28 - Trang 634-636 - 2003
Background: Active lower gastrointestinal (GI) bleeding is a potentially dangerous situation because patients with this condition may fall into shock. Colonoscopy, angiography, and scintigraphy have been used widely to localize the source of bleeding, but time is needed to perform these examinations. The purpose of this study was to illustrate how vividly enhanced computed tomography (CT) may show...... hiện toàn bộ
Transjugular liver biopsy using ultrasonographic guidance for jugular vein puncture and an automated device for hepatic tissue sampling: a retrospective analysis of 200 consecutive cases
Abdominal Imaging - Tập 33 - Trang 627-632 - 2008
We retrospectively evaluated the value of the combination of ultrasonographic guidance for jugular vein puncture and an automated biopsy device for transjugular liver biopsy. Transjugular liver biopsy was performed with ultrasonographic guidance for right internal jugular vein puncture and an automated device for hepatic tissue sampling (Quick-Core®) in 200 consecutive patients in whom percutaneou...... hiện toàn bộ
Perspective on radiation risk in CT imaging
Abdominal Imaging - Tập 38 - Trang 22-31 - 2012
Awareness of and communication about issues related to radiation dose are beneficial for patients, clinicians, and radiology departments. Initiating and facilitating discussions of the net benefit of CT by enlisting comparisons to more familiar activities, or by conveying that the anticipated radiation dose to an exam is similar to or much less than annual background levels help resolve the concer...... hiện toàn bộ
Thuyên tắc tĩnh mạch cửa gây tử vong sau liệu pháp tiêm ethanol xuyên qua da một lần điều trị ung thư biểu mô tế bào gan Dịch bởi AI
Abdominal Imaging - Tập 23 - Trang 608-610 - 2014
Hai tuần sau liệu pháp tiêm ethanol xuyên qua da để điều trị ung thư biểu mô tế bào gan, với việc tiêm 110 mL ethanol trong một phiên duy nhất dưới gây mê toàn thân, một phụ nữ 69 tuổi mắc xơ gan bù bắp tốt đã phát triển thuyên tắc toàn bộ hệ thống tĩnh mạch cửa, dẫn đến tình trạng cổ trướng không thể điều chỉnh và tình trạng chung của bà ngày càng xấu đi, dẫn đến tử vong 6 tuần sau thủ thuật.
