Abstract:
The objective of this work was to evaluate the radiation exposure received by workers in the nuclear medicine department of a private hospital in Bogotá, Colombia, during the period 2022-2023. The Hp (10) and Hp (0.07) readings for 15 workers including nuclear medicine (NM) physicians, nurses, and technologists who performed tasks in PET/CT and SPECT/CT were retrieved and analysed retrospectively. The results showed that in 2022, the average accumulated Hp (10) values for NM physicians, nurses, and technologists were, 1.5 ± 0.3 mSv, 1.9 ± 0.4 mSv, and 2.1 ± 0.6 mSv, respectively. Compared with 2022 (9.45 mSv vs 16.07 mSv), the mean annual extremity doses to nurses and technologists increased by 37.5% and 44.6%, respectively, in 2023 (15.11 mSv vs 29.05 mSv), due to the increase in the number of procedures. Technologists, particularly those responsible for preparing and administering the radiopharmaceuticals in PET/CT, recorded the maximum annual effective dose (3.0 mSv) and extremity dose (91.3 mSv) during 2022 and 2023.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
