Background: Image-guided radiotherapy used multiple imaging during the radiation therapy course to improve the precision and accuracy of health care provider's treatment. Objectives: This study aims to assess the safety, effectiveness and economic aspects of image-guided radiation therapy for decision-making about this technology in Iran. Methods: In this study, the most important med...

Conventional radiotherapy for cervical cancer relies on clinical examination, 3-dimensional conformal radiotherapy (3D-CRT), and 2-dimensional intracavitary brachytherapy. Excellent local control and survival have been obtained for small early stage cervical cancer with definitive radiotherapy. For bulky and locally advanced disease, the addition of chemotherapy has improved the prognosis but t...

BACKGROUND & OBJECTIVE Nasopharyngeal necrosis is an unusual sequelae after radiotherapy for nasopharyngeal carcinoma (NPC). It is mostly managed by conservative treatment, but the efficacy is unsatisfied. This study was to investigate the efficacy of endoscopy-guided debridement on irradiation-related nasopharyngeal necrosis in NPC patients after radiotherapy. METHODS Between Jul. 2006 and M...

The increasing interest in combined positron emission tomography (PET) and computed tomography (CT) to guide lung cancer radiation therapy planning has been well documented. Motion management strategies during treatment simulation PET/CT imaging and treatment delivery have been proposed to improve the precision and accuracy of radiotherapy. In light of these research advances, why has translati...

The appropriate application of 3-D conformal radiotherapy, intensity modulated radiotherapy or image guided radiotherapy for patients undergoing post-operative radiotherapy for prostate cancer requires a standardisation of the target volume definition and delineation as well as standardisation of the clinical quality assurance procedures. Recommendations for this are presented on behalf of the ...

The adverse side effects of gamma-ray radiotherapy can be reduced significantly by combining the treatment system with a real-time imaging system, used to precisely steer the radiation beam. MRI is a particularly attractive imaging modality for this, due to its excellent soft tissue contrast. A project is underway to combine a cylindrical, closed bore high-field MRI system with a 6 MeV Linac ra...

Volumetric imaging and planning for 3-dimensional (3D) conformal radiotherapy and intensity-modulated radiotherapy (IMRT) have highlighted the need to the oncology community to better understand the geometric uncertainties inherent in the radiotherapy delivery process, including setup error (interfraction) as well as organ motion during treatment (intrafraction). This has ushered in the develop...
