OBJECTIVES To evaluate the feasibility of dose-modulated retrospective ECG-gated thoracoabdominal aorta CT angiography (CTA) assessing abdominal aortic intimal flap motion and investigate the motion characteristics of intimal flap in acute aortic dissection (AAD). MATERIALS AND METHODS 49 patients who had thoracoabdominal aorta retrospective ECG-gated CTA(More)
PURPOSE To compare the image quality and diagnostic accuracy between sinogram affirmed iterative reconstruction (SAFIRE) algorithm and filtered back projection (FBP) reconstruction algorithm at 70 kVp-tube-voltage DSCT angiography in children with congenital heart disease (CHD). MATERIALS AND METHODS Twenty-eight patients (mean age: 13 months; range: 2-48(More)
PURPOSE To investigate the value of prospective ECG-gated high-pitch 128-slice dual-source CT (DSCT) angiography in the diagnosis of congenital extracardiac vascular anomalies in infants and children in comparison with transthoracic echocardiography (TTE). METHODS Eighty consecutive infants or children clinically diagnosed of congenital heart disease and(More)
So far, there is no satisfactory imaging modality to monitor antiangiogenesis therapy of ovarian cancer noninvasively. The aim of this study was to evaluate the effectiveness and sensibility of an 18F labeled Arg-Gly-Asp (RGD) peptide in imaging and monitoring antiangiogenic responds in SKOV-3 xenograft-bearing mice. 18F-FB-NH-PEG4-E[PEG4-c(RGDfK)]2(More)
OBJECTIVE To explore the clinical value of low-dose prospectively electrocardiogram-gated axial dual-source CT angiography (low-dose PGA scanning, CTA) in patients with pulsatile bilateral bidirectional Glenn shunt (bBDG) as an alternative noninvasive method for postoperative morphological estimation. METHODS Twenty patients with pulsatile bBDG (mean age(More)
PURPOSE Based on practice guideline of "management of hepatocellular carcinoma (HCC): update" published by American Association for the Study of Liver Diseases (AASLD) and "Barcelona Clinic Liver Cancer staging system (BCLC)," this study investigated how to enroll the optimal VX2 liver tumor model for HCC researches by dynamically observing the biological(More)
PURPOSE To investigate the coronary venous system and its relation to adjacent structures using 256-slice computed tomography (CT). MATERIALS AND METHODS The study consisted of 102 patients who underwent coronary CT angiography (CTA) using 256-slice CT. For each patient, the coronary venous system and its relation to adjacent structures were evaluated.(More)
The distribution of the geometric distances of connected neurons is a practical factor underlying neural networks in the brain. It can affect the brain´s dynamic properties at the ground level. Karbowski derived a power-law decay distribution that has not yet been verified by experiment. In this work, we check its validity using simulations with a(More)
BACKGROUND Accurate assessment of intra- as well as extra-cardiac malformations and radiation dosage concerns are especially crucial to infants and children with interrupted aortic arch (IAA). The purpose of this study is to investigate the value of prospective electrocardiogram (ECG)-triggered dual-source computed tomography (DSCT) angiography with(More)
