Object iveThe purpose is to study the feasibility of using11C-Acetate(11C-ACE)PET/CT for detecting urinary system tumour and evaluate the clinical diagnosis effect of11C-Acetate used as a complement of18F-FDG.Materials and Methods26patients suspicious of urinary system malignancy tumor and without any systematic therapy were collected between11/2010-03/2012, which include15cases of kindey occupying lesions and11of suspicious prostate diease.20male and6female with [...]
Radiation therapy plays an important role in the cancer treatment, which aims atmore precise beam control with, better efficacy and less damage. Intensity modulatedradiation therapy (IMRT) is dominate technology in current precise radiation therapy,since multi-leaf collimator (MLC) and the large gradient change in IMRT can lead tolarge bias in conventional dose calculation. In order to [...]
Objectives: To investigate the effect and mechanism of the role of basic fibroblastgrowth factor combined with bone mesenchymal stem cells in promoting healing ofβ-rayirradiated skin injury.Methods:1.3SD rats （age:6-8weeks old）, clean grade, were killed using cervical dislocationmethod. We obtained the femur and tibia bone marrow under sterile conditions, isolatedand cultured bone mesenchymal stem cells （BMSCs） by [...]
Objectives: To evaluate the clinical value of256-row Spiral CT andUltrasound in the diagnosis of aortic intramural hematoma(IMH).Methods：Between January2009and January201127patients (male19,female8) who were examined by256-row Spiral CT and Ultrasound werediagnosed with IMH. Scanner is Philips Brilliance256-row CT. Scan range isfrom thoracic entrance to bilateral common iliac artery.Double tube highpressure syringe inject a contrast agent.①Non ionic contrast [...]
