PURPOSE To prospectively investigate the effect of low tube voltage on radiation dose, contrast enhancement, image quality, and image noise at abdominal dynamic computed tomography (CT). MATERIALS AND METHODS The institutional review board approved this study. Prior informed consent was obtained from all patients. Forty patients (24 women, 16 men; mean(More)
PURPOSE To compare enhancement of the aorta, portal vein, liver, and tumor with contrast medium of a higher iodine concentration to that with one of a standard iodine concentration for liver dynamic CT within the same patient with known liver cirrhosis and hepatocellular carcinoma (HCC). MATERIALS AND METHODS Fifty-three patients with known cirrhosis and(More)
PURPOSE To reduce radiation dose from abdominal computed tomography (CT) without degradation of low-contrast detectability by using a technique with low tube voltage (90 kV). MATERIALS AND METHODS The institutional review board approved the participation of the radiologists in the observer performance test, and informed consent was obtained from all(More)
PURPOSE To evaluate prospectively bolus tracking to time hepatic arterial phase (HAP) imaging of hypervascular hepatocellular carcinomas (HCCs) with a 40-detector computed tomographic (CT) scanner. MATERIALS AND METHODS This study received institutional review board approval; informed consent was obtained. The study included 192 patients (123 men, 69(More)
BACKGROUND Non-water-soluble iron compounds have been reported to be less well absorbed than ferrous sulfate in young children, and concern has been raised about their usefulness as food fortificants. OBJECTIVE The objective was to evaluate the usefulness of ferrous fumarate and ferric pyrophosphate, compared with ferrous sulfate, in maintaining(More)
