Background:
Contrast media use is high in computed tomography (CT). This study aimed to explore radiographers' decision-making process when using contrast media injectors in the CT environment, with a focus on infection prevention and control (IPC).
Methods:
A qualitative study using observation within a think-aloud methodology in a simulated environment was undertaken. Participants performed all the steps to undertake a contrast-enhanced CT scan, while verbalizing their actions and process.
Results:
CT radiographers (n=20) participated in this study. Variations were observed across all stages of CT scanning. Gloves were used by a large proportion of participants while connecting the patient (n=16, 80%), followed by disconnecting from the patient (n=18, 90%).
Discussion:
To the best of our knowledge, this is the first study to map steps and explore radiographers' decision-making relating to contrast-enhanced CT procedures. Justification of practice centered around patient care and self-protection factors, using routine IPC practice and awareness of IPC risks.
Conclusions:
There was inconsistency between participants in terms of workflow and order of steps setting up a patient in CT, along with variations in IPC practices. The lack of universal guidelines specific to IPC in CT has manifested as variations in practice across CT departments.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...

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...
