Lens of Eye Dose Assessment for Nuclear Medicine and PET Technologists
Background In 2021, the Canadian Nuclear Safety Commission (CNSC) adjusted the equivalent dose limit for the lens of the eye to 50 mSv in a one-year period based on a recommendation made by the International Commission on Radiological Protection (ICRP). This is a significant reduction from the previous limit of 150 mSv in a year. […]
Enhancing Eye Dose Monitoring in Radiation Protection: Evaluating Hp(0.07) and OSLDs as an Alternative to Hp(3)
Background Occupational exposure to ionizing radiation is a significant concern for medical workers, particularly those in interventional radiology and nuclear medicine. Radiation-induced cataract formation has led to stricter dose limits for the eye lens, as recommended by the International Commission on Radiological Protection (ICRP) [1]. Traditionally, Hp(3) has been the preferred metric for assessing eye […]
AI-Driven Enhancement of Low-Count Lung Scintigraphy: Optimizing Radiation Safety and Imaging Efficiency with cGANs
Background Lung ventilation/perfusion (V/Q) scintigraphy is a crucial imaging tool for diagnosing pulmonary embolism (PE). Transitioning exclusively to single photon emission computed tomography (SPECT) acquisitions presents challenges for clinicians accustomed to interpreting traditional planar lung scintigraphy. Additionally, standard acquisition protocols for lung SPECT and planar V/Q scintigraphy, designed to produce high-quality images, are time-consuming and […]
