AIM To investigate the correlation of iodine concentration (IC) generated by spectral computed tomography (CT) with micro-vessel density (MVD) and vascular endothelial growth factor (VEGF) expression in patients with advanced gastric carcinoma (GC). METHODS Thirty-four advanced GC patients underwent abdominal enhanced CT in the gemstone spectral imaging mode. The IC of the primary lesion in t...

Although anti-programmed death 1 (PD-1) antibody plus chemotherapy has recently been approved for first-line (1L) ESCC, death-ligand (PD-L1) may offer another combination option in this setting. Sugemalimab (Suge), an anti-PD-L1 monoclonal antibody, fluorouracil and cisplatin (FP) regimen demonstrated preliminary anti-tumor activity a phase 1b cohort of patients (pts) with advanced ESCC. We pre...

Findings on the impact of perceived risk and trust in online purchasing are usually based on evidence obtained from the purchase of inexpensive, uncomplicated, and hence low risk products such as books, compact disks (CD’s, DVD’s), or clothing. Antecedents of perceived risk and trust are also not usually addressed in these studies. This study shows that the type of Internet marketing strategy (...

1 Abstract Computerized databases are essential and inseparable components of a vast majority of today's information systems. Database systems are used at all levels of management, research and production to provide uniform access and control of consistent information. Computer aided software engineering system require extensive database system support. Several industrial and academic research ...

Although dual-energy CT (DECT) was first conceived in the 1970s, it was not widely used for CT indications. Recently, the simultaneous acquisition of volumetric dual-energy data has been introduced using multidetector CT (MDCT) with two X-ray tubes and rapid kVp switching (gemstone spectral imaging). Two major advantages of DECT are material decomposition by acquiring two image series with diff...

BACKGROUND Lung cancer is the most common cancer which has the highest mortality rate. With the development of computed tomography (CT) techniques, the case detection rates of solitary pulmonary nodules (SPN) has constantly increased and the diagnosis accuracy of SPN has remained a hot topic in clinical and imaging diagnosis. The aim of this study was to evaluate the combination of low-dose spe...

Increasingly wider availability of biomedical imaging modalities, such as X-ray computed tomography (CT), magnetic resonance imaging (MRI), ultrasonic imaging, positron emission tomography (PET), single-photon emission computed tomography (SPECT), and optical imaging, have led to significant progresses in both biomedical research and clinical practice. Advancements in imaging technology and ima...
