Patterns of Pelvic Radiotherapy in Patients with Stage II/III Rectal Cancer
(2013)High-level evidence supports adjuvant radiotherapy for rectal cancer. We examined the influence of sociodemographic factors on patterns of adjuvant radiotherapy for resected Stage II/III rectal cancer. Methods. Patients ... -
The Potential Role of Magnetic Resonance Spectroscopy in Image-Guided Radiotherapy
(2014-05)Magnetic resonance spectroscopy (MRS) is a non-invasive technique to detect metabolites within the normal and tumoral tissues. The ability of MRS to diagnose areas of high metabolic activity linked to tumor cell proliferation ... -
Proctitis following stereotactic body radiation therapy for prostate cancer
(2014-12)Background Proctitis after radiation therapy for prostate cancer remains an ongoing clinical challenge and critical quality of life issue. SBRT could minimize rectal toxicity by reducing the volume of rectum receiving ... -
Prognostic factor from MR spectroscopy in rat with astrocytic tumour during radiation therapy
(2014-11-27)Objective: To investigate the relationship between the tumour volume and metabolic rates of astrocytic tumours using MR spectroscopy (MRS) during radiation therapy (RT). Methods: 12 healthy male Sprague-Dawley® rats ... -
Radiation isocenter measurement devices and methods and 3-D radiation isocenter visualization systems and related methods
(2008-05-25)A three-dimensional phantom assembly for use with a radiation treatment device includes a three-dimensional support member having at least two, spaced apart opposed surfaces configured to hold at least one generally planar ... -
Radioprotective Effect of American Ginseng on Human Lymphocytes at 90 Minutes Post-irradiation: A Study of 40 Cases
(East Carolina University, 2010-05)Backgroundâ Ionizing radiation (IR) initiates intracellular oxidative stress through enhanced formation of reactive oxygen species (ROS) that attack DNA leading to cell death. As the diversity of IR applied in medicine, ... -

Total error shift patterns for daily CT on rails image-guided radiotherapy to the prostate bed
(2011)Background To evaluate the daily total error shift patterns on post-prostatectomy patients undergoing image guided radiotherapy (IGRT) with a diagnostic quality computer tomography (CT) on rails system. Methods A ... -
A Tri-Modality Image Fusion Method for Target Delineation of Brain Tumors in Radiotherapy
(2014)Purpose To develop a tri-modality image fusion method for better target delineation in image-guided radiotherapy for patients with brain tumors. Methods A new method of tri-modality image fusion was developed, ... -
Yttrium-90 Radioembolization in Patients with Hepatocellular Carcinoma Who have Previously Received Sorafenib
(2013-11)Purpose: Yttrium-90 radioembolization (RE) is a locoregional therapy option for hepatocellular carcinoma (HCC). Sorafenib is a multikinase inhibitor used in HCC that can potentially affect the efficacy of RE by altering ...
