Radiologic Technologists' Perceived Reasons for Inappropriate Imaging
1Quentin T Moore, PhD, R.T.(R)(T)(QM), is director of imaging sciences and associate professor for Mercy College of Ohio.
Purpose:
To examine whether radiologic technologists' perceptions of imaging appropriateness differed based on their primary imaging modality, work shift, shift length, and primary practice type.
Methods:
A national, cross-sectional study was conducted in the fourth quarter of 2019 using a simple, randomized sample of American Society of Radiologic Technologists (ASRT) members. Study participants were employed in health care settings in radiography, computed tomography (CT), mammography, or radiology leadership. Seven potential reasons for inappropriate imaging procedures (ie, patient expectations, provide patient with a feeling of being taken seriously, lack of time, expectations from relatives, compensation for insufficient clinical examination, normal findings would reassure the patient, and fear of lawsuits) were evaluated for relationships with their primary imaging modality, work shift, shift length, and primary practice type.
Results:
Disparities in perceived reasons affecting imaging appropriateness were found. Providing the patient with a feeling of being taken seriously was related to primary practice type (P = .022). Lack of time was related to primary imaging modality (P = .005) and primary practice type (P = .006). Expectations from relatives was related to primary imaging modality (P = .016) and primary practice type (P = .027). Compensation for insufficient clinical examination was related to primary imaging modality (P < .001), shift length (P = .011), work shift (P = .002), and primary practice type (P < .001). Fear of lawsuits was related to primary imaging modality (P = .001)) and work shift (P = .002).
Discussion:
The study reveals that radiologic technologists' perceptions of patient-centered factors and defensive medicine-related factors differ among imaging modalities, shift types, and practice settings. However, more research is required to determine why radiologic technologists perceive these reasons to be present, investigate whether providers feel similarly, and determine perceptual alignment with evidence-based guidelines.
Conclusion:
The findings suggest that attention should focus on the appropriateness of CT imaging procedures performed in hospitals during night shifts.

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...

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
