Radiation exposure to nuclear medicine technologists performing a V/Q PET: Comparison with conventional V/Q scintigraphy, [F]FDG PET and [Ga]Ga DOTATOC PET procedures.

Introduction: Ventilation/Perfusion (V/Q) PET/CT is an emerging imaging modality for regional lung function evaluation. The same carrier molecules as conventional V/Q scintigraphy are used but they are radiolabelled with gallium-68 (Ga) instead of technetium-99m (Tc). A recurrent concern regarding V/Q PET imaging is the radiation dose to the healthcare workers.

In vivo validation of Dosemap software use in interventional cardiology with dosimetrics indicators and peak skin dose evaluation.

Objectives: The aim of this study was to determine the accuracy of DoseMap™ software as compared to gafchromic film in real clinical practices.

Background: The radiation exposure from cardiovascular procedures could expose patients to potential risk of cancer and/or skin injury. New tools like Dosemap software were developed to estimate the patient skin dose in the cardiac catheterization laboratory.
