BACKGROUND & OBJECTIVE Sentinel lymph node (SLN) identification has been increasingly used in the treatment design of a variety of solid tumors, particularly breast cancer and melanoma. A negative SLN predicts the absence of tumor metastases in the regional lymph nodes with high accuracy. This study was to investigate the clinical value of combined(More)
AIM Esophageal cancer remains a significant health problem worldwide. It is important to investigate alterations in expression of retinoic acid receptor-beta, p 53 and Ki67 proteins in esophageal carcinogenesis. METHODS To find biomarkers for early identification of esophageal cancer, we analyzed the retinoic acid receptor-beta, p 53 protein and the(More)
Structures were obtained from images with morphological characteristics to register with voxel-based method. We applied simple morphological operations to obtain human brain cortex and chose normalized mutual information as similarity measure for the geometric alignment of PET and MR images. Evaluation used nine patients, and the results showed that(More)
BACKGROUND & OBJECTIVE Radiation-induced lung injury is commonly following radiotherapy (RT)for tumors in,and around the thorax. Lung function is usually assessed by pulmonary function tests (PFTs), but RT-induced regional changes of pulmonary function cannot be accurately evaluated by PFTs. Lung perfusion scintigraphy compared with other radiographic(More)
BACKGROUND & OBJECTIVE Carcinoembryonic antigen(CEA), is highly expressed in many kinds of carcinomas, especially in colon carcinoma. Anti-CEA antibodies have great application in diagnosis and therapy of the patients with colon carcinoma. This study was designed to investigate the biodistribution and radioimmunodetection in nude mice bearing human colon(More)
