Summary
Radiographer preliminary image evaluation (PIE) accuracy is not significantly impacted by imaging workload. While accuracy remained high, it dipped below 85% when workload exceeded 7 exams per hour.
Area of Science:
- Medical Imaging
- Radiography
- Healthcare Management
Background:
- Radiographer preliminary image evaluation (PIE) adoption in Australia is slow despite proven accuracy.
- A perceived lack of time due to imaging workload is a barrier to PIE implementation.
Purpose of the Study:
- To investigate the correlation between radiographer imaging workload and the accuracy of PIE services.
- To determine if workload is a significant barrier to PIE service implementation.
Main Methods:
- Correlational analysis of 45,373 exams and 1152 PIE comments (Jan-Dec 2022).
- PIE comment accuracy was compared against radiologist reports.
- Imaging workload was categorized into three 8-hour shifts.
Main Results:
- No statistically significant linear association was found between increased workload and reduced PIE accuracy (P=0.136).
- Average PIE accuracy consistently fell below 85% when the workload exceeded 7 exams per hour.
Conclusions:
- Perceived workload is not a statistically significant barrier to radiographer PIE service accuracy.
- While not statistically significant, accuracy decline above 7 exams/hour warrants attention.

169
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Description
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...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (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...
