Purpose:
To assess whether alterations in the type of duty assignment system can affect the reading efficiency and stress level of diagnostic radiologists.
Materials And Methods:
Fourteen board-certified diagnostic radiologists were enrolled. We investigated three different reading systems for 1 week each. System 1 is our default, in which there are no assigned duties and everyone finishes when all cases are done. In system 2, two late shift readers are assigned every day, and, after everyone else leaves at a fixed time (5:30 p.m.), they take all remaining cases until they are finished. In system 3, a dedicated single reader is assigned to finish 30 cases, and everyone else will read all remaining cases. The total time required for reading and the number of cases read were recorded. In addition, participants completed two questionnaires regarding work-related stress.
Results:
There was a trend toward shorter finishing time in system 2 and 3 compared to system 1 (P = 0.072 and 0.012). In terms of working stress, the subjective burden was lighter when systems 2 or 3 were employed.
Conclusion:
Minor modification of the duty assignment system has the potential to improve working efficiency and may reduce the work-related stress of diagnostic radiologists.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
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...

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...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
