Objective:
We assess the utility of transparent 3D reconstructed CT images for evaluation of traumatic pelvic bony injuries compared to traditional radiographs.
Methods:
Radiographs and 3D reconstructed CT were anonymized and randomized before review by 4 board certified physicians using a standardized questionnaire and compared to a gold-standard axial CT by a fifth board certified physician.
Results:
49 patients were included. We found significant agreement (K=[0.5-0.92], p<0.001) and comparable accuracy (K=[0.36-0.38], p<0.02) and ghost images of radiographs and transparent 3D reconstructed CT without a difference in confidence (p=0.38).
Conclusion:
Transparent 3D reconstructed CT images may be sufficient for pelvic trauma injury without the use of radiographs.

Computed Tomography
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...

Imaging Studies for Cardiovascular System III: X-Ray
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...

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
