Introduction: Boron neutron capture therapy (BNCT) is a method of cancer treatment and potentially, two borono-L-phenylalanine (BPA) and sodium borocaptate (BSH) are used in BNCT as common boron carriers. Some previous studies have shown that the dose rate is directly related to boron concentration in the tissue. This study aimed to simulate the structure of boron carriers and brain tumor compo...

Fluorine-18-fluorodeoxyglucose- positron emission tomography ((18)F-FDG PET) in head and neck cancer patients is useful for staging, identification of macroscopic disease, detection of invaded lymph nodes and distant metastases, delineation of radiotherapy target volume and assessment of treatment response. This brief review addresses the potential role of PET in radiotherapy planning as compar...

OBJECTIVES The relation of PET-derived parameters as maximum standardized uptake value (SUVmax), total lesion glycolysis (TLG), metabolic tumor volume (MTV) with clinical stage in lung cancer and correlation of SUVmax of primary tumor and that of metastatic lesion was studied in lung cancer patients. MATERIALS AND METHODS Patients with lung cancer who were referred for FDG PET/CT were include...

OBJECTIVE The aim of this study was to evaluate a 3D tumor segmentation method for fluorodeoxyglucose positron emission tomography (FDG-PET) in the context of noninvasive estimation of tumor metabolic length (Lm), as it correlates with surgical pathology and phantom results. METHODS Thirty-four patients (7 women, 27 men) with esophageal cancer were retrospectively evaluated. All patients unde...

18 F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) allows to quantify the metabolic activity of a tumor (glycolysis) and has become a reference tool in oncology for the staging, restaging, radiotherapy planning and monitoring response in many cancers. Quantitative analyses have been introduced in order to overcome some of the limits of the visual methods...

objective(s): the goal of this study was assessing the prophylactic effect of exercise and its role as an adjuvant therapy on level of cytokines involved in angiogenesis in estrogen-dependent breast cancer. materials and methods: forty female balb/c mice were randomly assigned to exercise-tumor-exercise (ete), exercise-tumor-rest (etr), rest-tumor-exercise (rte) and rest-tumor-rest (rtr) groups...

Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) is widely applied in non‐small cell lung cancer (NSCLC). The standardized uptake value (SUV), a semi‐quantitative index, plays an essential role in NSCLC for diagnosis, staging, and efficacy evaluation. It has been proposed that the SUVmax of tumors may correlate with the presence or absence of chemotherapy resista...

This study aimed to investigate whether the predictive values of intensity- and volume-based PET parameters are different between histological subtypes in patients with cervical cancer. Ninety patients, 65 with squamous cell carcinoma (SCC) and 25 with non-SCC (NSCC), who underwent pretreatment ¹⁸F-FDG PET/CT and pelvic MRI, were studied retrospectively. In addition to SUVmax and SUVmean, metab...
