Trauma imaging using computed tomography (CT) and radiographs shows declining radiation exposure over time. However, adult trauma patients still receive significantly higher radiation doses than pediatric and geriatric patients.
Area of Science:
- Radiology
- Trauma Care
- Medical Imaging
Background:
- Traumatic injuries necessitate imaging, often involving significant radiation exposure.
- Plain radiographs and computed tomography (CT) are standard trauma imaging modalities.
- Concerns exist regarding radiation's adverse effects, particularly in vulnerable populations like children.
Purpose of the Study:
- To assess trends in radiation exposure during trauma assessment.
- To analyze imaging radiation doses at a Level I trauma center.
Main Methods:
- Retrospective analysis of a de-identified trauma registry dataset.
- Calculation of total radiation amounts based on diagnostic modality (radiographs, CT scans).
- Assignment of effective radiation dose using American College of Radiology values.
Main Results:
- A positive correlation exists between injury severity score and effective radiation dose.
- Radiation exposure decreased significantly from 2016 to 2021.
- Adult trauma patients (16.32 mSv) received higher doses than pediatric (6.32 mSv) and geriatric (12.67 mSv) patients.
Conclusions:
- The Level I trauma center has successfully reduced radiation exposure through current protocols.
- Adults incur the highest radiation doses compared to pediatric and geriatric trauma patients.
- CT and radiography are vital but require judicious use in trauma imaging.

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...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
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...
