OBJECTIVES To compare accuracy, image quality and radiation dose between high-pitch spiral and sequential modes on 128-slice dual-source computed tomographic (DSCT) angiography in children with congenital heart disease (CHD). METHODS Forty patients suspected with CHD underwent 128-slice DSCT angiography with high-pitch mode and sequential mode(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)
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)
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)
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 evaluate the feasibility of high-pitch spiral CT in imaging vascular anomalies (VAs) with affluent blood flow in the head and neck of infants and children. METHODS For patients with suspected VAs and affluent blood flow pre-detected by ultrasound, CT was performed with high-pitch mode, individualized low-dose scan protocol and(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)
AIM To evaluate whether some magnetic resonance imaging (MRI) signs suggesting idiopathic intracranial hypertension (IIH) could also be found in intracranial hypertension (IH) due to cerebral venous thrombosis (CVT) and to assess their possible contribution to diagnosing this disorder. MATERIALS AND METHODS Thirty-one patients with IH due to CVT were(More)
