PURPOSE The aim of this study was to examine the neural bases for the exceptional mental calculation ability possessed by Chinese abacus experts through PET imaging. METHODS We compared the different regional cerebral blood flow (rCBF) patterns using (15)O-water PET in 10 abacus experts and 12 non-experts while they were performing each of the following(More)
OBJECTIVE The use of the micro positron emission tomography (microPET) technique provides a powerful means for molecular imaging on small animals, while its inferior spatial resolution offers insufficient anatomical information which impedes the interpretations of the scans. To improve this limitation, it often relies on a clinical magnetic resonance(More)
CyberKnife is one of multiple modalities for stereotactic radiosurgery (SRS). Due to the nature of CyberKnife and the characteristics of SRS, dose evaluation of the CyberKnife procedure is critical. A radiophotoluminescent glass dosimeter was used to verify the dose accuracy for the CyberKnife procedure and validate a viable dose verification system for(More)
PURPOSE Coronary artery calcification (CAC) scores are widely used to determine risk for Coronary Artery Disease (CAD). A CAC score does not have the diagnostic accuracy needed for CAD. This work uses a novel efficient approach to predict CAD in patients with low CAC scores. MATERIALS AND METHODS The study group comprised 86 subjects who underwent a(More)
Most patients with liver cirrhosis must undergo a series of clinical examinations, including ultrasound imaging, liver biopsy, and blood tests. However, the quantification of liver cirrhosis by extracting significant features from a T2-weighted magnetic resonance image (MRI) provides useful diagnostic information in clinical tests. Sixty-two subjects were(More)
Multi-detector CT (MDCT) is increasingly utilized for the investigation of neurovascular disease in recent year, but limited in z-axis coverage (3.2cm for 64-MDCT) with about 9′12 mSv for small area of the brain close to Circle of Willis. Our aim of the study is to evaluate 4-dimensional (4D) cerebral vessels and whole brain perfusion with 5′7(More)
