OBJECTIVE To investigate the role of first pass dynamic 16-slice spiral computed tomography in the evaluation of tumor angiogenesis in patients with non-small cell lung cancer (NSCLC) and to assess its importance in predicting pathologic characteristics. METHODS The first pass dynamic 16-slice spiral computed tomography was performed in 33 patients with(More)
The aim of this study was to evaluate the oxygen partial pressure of the rabbit model of the VX2 tumor using a 64-slice perfusion CT and to compare the results with that obtained using the oxygen microelectrode method. Perfusion CT was performed for 45 successfully constructed rabbit models of a VX2 brain tumor. The perfusion values of the brain tumor(More)
This study sought to determine the expression of angiopoietin-2 (Ang-2) and vascular endothelial cell growth factor (VEGF) in oral squamous cell carcinoma (OSCC) and assess their correlations with tumor progression, angiogenesis, vessel maturation, and clinical survival. Tumor tissue from 102 OSCC patients, adjacent noncancerous oral tissue from 79 OSCC(More)
CT perfusion imaging is a promising technique for delineating the target volume for three-dimensional conformal radiotherapy, but it is difficult in humans to obtain gross pathological samples at the same level of the brain tumor to evaluate this technique. The aim of this study was to use the BV map of CT perfusion imaging to assess the target volume in(More)
OBJECTIVE To study the effectiveness and safety of acellular dermal matrix (ADM) graft in preventing Frey syndrome after parotid neoplasm surgery, we reviewed foreign reported clinical randomized controlled trials systematically. Based on this review, we aimed to assess the effectiveness of ADM graft and provide reliable evidence for clinical application.(More)
OBJECTIVE Tumor hypoxia can influence response to radiotherapy and other treatment modalities. Oxygenation status is proved to be an independent prognostic factor. 99mTc-HL91 (99mTc labeled 4,9-diaza-3,3,10,10-tetramethyldodecan-2,11-dione dioxime) is a potential noninvasive marker of tumor hypoxia. It has been reported that 99mTc-HL91 has certain validity(More)
