What role do imaging studies play in the assessment of whiplash injuries in primary care?

Role of Imaging in Whiplash Injuries in Primary Care

In primary care, imaging studies are generally not routinely indicated for the assessment and management of whiplash injuries unless there are specific clinical concerns suggesting a more serious cervical spine injury.

Imaging, such as plain X-rays or CT scans, is reserved for cases where there is suspicion of cervical spine injury based on clinical assessment, including the presence of high-risk factors (e.g., neurological deficits, dangerous mechanism of injury, midline cervical tenderness) or inability to safely assess neck range of movement.

For adults, CT cervical spine scans are recommended urgently if high-risk factors are present or if the Canadian C-spine rule indicates imaging is necessary. MRI is reserved for cases with neurological abnormalities or when further detail is needed after CT.

In the absence of these indications, imaging is not routinely required, and management focuses on clinical assessment and symptom control.

This approach helps avoid unnecessary radiation exposure and resource use while ensuring that serious injuries are not missed.

Therefore, in primary care, the role of imaging in whiplash is primarily to exclude cervical spine fractures or significant injury when clinical suspicion arises, rather than for routine evaluation of whiplash symptoms.

Referral for imaging should follow established clinical decision rules and guidelines to identify those at risk of cervical spine injury.
