Aim:
To explore the nature and extent of peer-reviewed literature related to the use of diagnostic imaging by nurse practitioners (NPs) to inform future practice and research.
Background:
Nurse practitioners undertake advanced assessment, diagnosis, and management of patients, including requesting and interpretation of diagnostic imaging. It is unclear what evidence exists related to the quality use of radiological investigations by NPs in recent years.
Design:
A scoping review based on the steps suggested by the Joanna Briggs Institute.
Methods:
A structured review of the databases Medline, CINAHL and Embase was undertaken using the keywords and MESH terms 'nurse practitioner', 'medical imaging', 'diagnostic imaging', 'scan' and 'radiography'. Only English language articles were included, and no date limit was applied. Database review was completed on 30 May 2021.
Results:
Eight themes were identified-country and clinical context, requesting diagnostic imaging, performing diagnostic imaging, image-guided interventions, interpreting diagnostic imaging, training education and knowledge, impact on resource usage and comparison with medical practitioners. There were more studies across a greater breadth of clinical specialties and imaging modalities in the United States than in other countries. Nurse practitioner practice is frequently benchmarked against that of medical colleagues. There is a paucity of studies focusing on educational preparation and the lack of relevant university curricula for NPs around diagnostic imaging.
Conclusion:
There are significant gaps in the evidence outside of the United States across several of the identified themes. Further studies are needed to explore NP access to and use of diagnostic imaging and to understand the barriers and facilitators to this.
Relevance To Clinical Practice:
Studies from four countries were included in this review. The evidence suggests that, where studied, nurse practitioners (NPs) can safely and appropriately request and interpret plain x-rays in the emergency and minor injuries setting. Further research is needed to evaluate the educational needs of NPs in relation to diagnostic imaging and their use of advanced imaging techniques, particularly outside of the United States.
Patient Or Public Contribution:
No patient or public contribution.

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...
