BACKGROUND The purpose of this study was to determine the feasibility of nondaily image-guided radiotherapy (RT) strategies with intensity-modulated radiotherapy (IMRT) for head and neck cancer. METHODS Alignment data was analyzed from 103 consecutive patients treated by IMRT for head and neck cancer who had undergone daily imaging with onboard mega-voltage CT (MVCT), resulting in 3275 images...
Technological advancement has facilitated patient-specific radiotherapy in bladder cancer. This been made possible by developments image-guided (IGRT). Particularly transformative the integration of volumetric imaging into workflow. The ability to visualise target using cone beam computed tomography and magnetic resonance initially assisted with determining magnitude inter- intra-fraction chang...
The objective of this study was to compare the effects of image-guided hypofractionated radiotherapy and conventional fractionated radiotherapy on non-small-cell lung cancer (NSCLC). Fifty stage- and age-matched cases with NSCLC were randomly divided into two groups (A and B). There were 23 cases in group A and 27 cases in group B. Image-guided radiotherapy (IGRT) and stereotactic radiotherapy ...
introduction: lung cancer is one of the leading causes of cancer related deaths in the world. the incidence of lung cancer is increasing in india and there is a need to understand the natural history of this disease. aim of the study: to study the clinico- pathological- radiological profile of patients diagnosed with lung cancer from january 2013 to may 2015 at a tertiary care teaching hospital...
the evaluate the diagnostic value of image guided fine needle aspiration (fna) in breast lesions, the cytologic results of 401 patients were studied. all patients had either unpalpable masses or lesions who were hardly possible to localize by palpation and fna was performed by single radiologist under ultrasound guide in all cases. the cytologic results were divided into four categories (inconc...
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...
