BackgroundThe development of radiation pneumonitis (RP) after Stereotactic Body Radiotherapy (SBRT) is known to be associated with many different factors, although historical analyses of RP have commonly utilized heterogeneous fractionation schemes and methods of reporting. This study aims to correlate dosimetric values and their association with t...

BackgroundAfter each cycle of [177Lu]-DOTA-TATE peptide receptor radionuclide therapy (PRRT) dosimetry is performed to enable precise calculation of the radiation-absorbed dose to tumors and normal organs. Absorbed doses are routinely calculated from three quantitative single-photon emission computed tomography (SPECT) studies corrected by computed...

Interventional radiologists/cardiologists are repeatedly exposed to low radiation doses which makes them the group of the highest occupational exposure and put them at high risk of stochastic effects. Routine monitoring of staff is usually performed by means of passive dosimeters. However, current personal dosimeters are subject to large uncertaint...

BackgroundComputed tomography (CT) scans are routinely performed in positron emission tomography (PET) and single photon emission computed tomography (SPECT) examinations globally, yet few surveys have been conducted to gather national diagnostic reference level (NDRL) data for CT radiation doses in positron emission tomography/computed tomography ...

The purpose of study is to investigate the dosimetry of electron intraoperative radiotherapy (IOERT) of the Intraop Mobetron 2000 mobile LINAC in treatments outside of the breast. After commissioning and external validation of dosimetry, we report in vivo results of measurements for treatments outside the breast in a large patient cohort, and inves...

SABR offers an effective treatment option for clinically localized prostate cancer. Here we report the dosimetric predictors of late toxicity and quality of life (QOL) in a pooled cohort of patients from four phase II trials. The combined cohort included all three prostate cancer risk groups. The prescription dose was 35-40 Gy in 5 fractions. Toxic...

Recently, there has been a significant amount of interest in studying the importance of radiation doses to the eye lens during endoscopic retrograde cholangiopancreatography (ERCP). A study that focused on measuring the scattered radiation using an ionization chamber survey meter reported that a lead curtain was useful in reducing the scattered rad...

IntroductionA new therapeutic option for metastatic castration–resistant prostate cancer (mCRPC) of heavily pre-treated patients lies in 177Lu-PSMA-617 radioligand therapy.MethodsOn the basis of PSMA-targeted 68Ga-PSMA-11 PET/CT, 32 consecutive mCRPC patients were selected for 177Lu-PSMA-617 therapy (6 GBq/cycle, 2 to 6 cycles, 6–10 weeks apart) an...

L'évaluation des grandeurs dosimétriques de protection utiles au respect des trois principes de la radioprotection est réalisée par des instruments de mesure de rayonnements ionisants. Par l'intermédiaire de leur étalonnage, lequel doit être contrôlé périodiquement, ces instruments délivrent une indication de la grandeur dosimétrique opérationnelle...
