PURPOSEImage-guided adaptive brachytherapy (IGABT) recently has shown excellent clinical outcomes with superior local control and less toxicity. For IGABT, T2W (T2-weighted) MRI is the gold standard. However, studies have that target delineation same results in uncertainties, poor interobserver variabilities, low conformity indices for high-risk volume contours. In this study, we investigate ro...

Brachytherapy reduces the post radiation sequalae as dose required is lower than external beam therapy (EBRT) and limits area of exposure. This case report outlines two different patients managed by fabrication carrier prosthesis for duration brachytherapy.

introduction in this study, we aimed to calculate dose enhancement factor (def) for gold (au) and iron (fe) nanoparticles (nps) in brachytherapy and teletherapy, using monte carlo (mc) method. materials and methods in this study, a new algorithm was introduced to calculate dose enhancement by aunps and fenps for iridium-192 (ir-192) brachytherapy and cobalt-60 (co-60) teletherapy sources, using...

Background: Toxicity assessment is done by comparing HDR brachytherapy with ICRU point doses. D2cc doses of OAR in slightly more than Objectives:The primary objective volumetric dose and toxicity comparison between brachytherapy. Materials Methods: It a prospective comparative study. The total number patients enrolled the study 20. After obtaining informed consent, then were All diagnosed H.P.E...

BACKGROUND We reviewed the outcomes of oropharyngeal squamous cell carcinoma treated with external beam radiation and interstitial brachytherapy. METHODS Ninety patients with squamous cell carcinoma of the oropharynx were treated with interstitial brachytherapy at the University of Utah between 1984 and 2001. Seventy-two patients received external beam radiotherapy (EBRT) followed by brachyth...

OBJECTIVE The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. METHODS Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information...

On the other hand, brachytherapy combined with external beam irradiation is not a good therapeutic approach in advanced disease because, in this case, the brachytherapy target volume would be by definition identical for a primary brachytherapy and/or for a brachytherapy boost. (8,11) For any tumour size, the combination of external beam irradiation and brachytherapy boost yields worse results t...

Introduction: Gynecological malignancies present challenges in determining an appropriate volumetric dose due to the highly variable physiologic activity of the surrounding tissue. Because of the high doses used in brachytherapy, surrounding structures have the potential to move around in the dose region and receive unknown amounts of radiation. Calculating hotspot region from ...
