Trauma Scan - What Is Its Role In Trauma Injury?
A quick computed tomography procedure known as a "trauma scan" (TS) may be used to obtain high-resolution investigations of the head, cervical spine, chest, belly, and pelvis. When CT first became available, it had little use in assessing patients who had suffered repeated traumas.
The scanning time for specific bodily parts was between twenty and thirty minutes. The introduction of rapid CT scanners completely changed the way that numerous traumas were imaged.
Whole-body trauma scanning has been shown to reduce mortality and morbidity due to its rapid diagnosis. Whole-body trauma CT scans may not always be properly interpreted at first. This issue may be resolved if another radiologist were to review the case.
Scanning the head and cervical spine without contrast is the first step in the conventional CT procedure for a whole-body trauma scan, which is followed by a 30-second scan of the chest during the arterial phase and a 70-second scan of the belly and pelvis during the portal venous phase.
Prior to the 70-second scan, several trauma centers additionally get an arterial phase scan of the belly and pelvis. Both the coronal and sagittal planes are used to reformat pictures of the whole body such that they seem like thin axial slices.
Alternatives include runoff CT angiograms of the lower limbs and arterial phase pictures of the head and neck when medically necessary. The radiologist conducting and evaluating a whole-body CT scan must manage and interpret hundreds of CT pictures, including those of the lungs, soft tissues, and bones.
It is extremely difficult for teleradiologists who operate alone. Another difficulty is the urgent need to review and correctly interpret scans in order to rapidly discover potentially life-threatening or otherwise crucial diagnoses.
It's reasonable to assume that certain injuries won't be noticed during the first analysis of CT scans of the whole body that has been subjected to trauma. A second radiologist's opinion might help resolve this issue.
How to read a Body CT for Trauma
Injuries to ligaments, tendons, muscles, and cartilage, such as meniscal tears, may be seen clearly on an MRI due to the high contrast resolution it provides.
Patients with blunt abdominal injuries who are otherwise clinically stable are evaluated by computed tomography (CT) imaging at present. CT can quickly and accurately look at the abdominal organs, the retroperitoneum, and the abdominal wall. It can also look at the lower thoracic area and the boney pelvis, but not as well.
Painless and quick, CT scans are now possible with state-of-the-art equipment. It usually only takes approximately 30 minutes to complete the full procedure.
A trauma scan is an efficient method of assessing trauma patients for the brain, cervical spine, chest, abdominal, and pelvic injuries that may affect morbidity and mortality. The trauma scan was completely transformed by whole-body CT scanning.
Sometimes, however, injuries are overlooked during first scan interpretations; in such cases, a second radiologist may help. All whole-body CT images may not be able to be reread, but in the future, radiologists will benefit from knowing what elements are linked to a higher rate of missing damage.
