For differentiating between tension headache and cervicogenic headache, MRI of the cervical spine is the preferred imaging modality as it visualizes soft tissues, nerve roots, and potential disc pathology, especially in cases where cervicogenic headache is suspected due to its ability to identify issues in the neck that may be causing the headache. When considering the diagnosis of tension headaches versus cervicogenic headaches, it's crucial to understand that tension headaches are typically diagnosed clinically based on symptoms such as bilateral pressure or tightness without significant neurological findings 1. In contrast, cervicogenic headaches, which originate from neck structures, may benefit from targeted imaging studies focusing on the cervical spine 2, 3. The choice between imaging modalities depends on clinical suspicion, with MRI being more sensitive for soft tissue pathologies and CT better for bony abnormalities 4. Key points to consider in the diagnosis and management of these headaches include:
- Clinical diagnosis of tension headaches based on symptoms
- Targeted imaging for cervicogenic headaches, with MRI preferred for soft tissue and disc pathology
- CT of the cervical spine for suspected bony abnormalities
- Limited utility of X-rays but potential use as an initial screening tool for cervical spine alignment issues
- Importance of clinical suspicion and physical examination findings, such as reduced cervical range of motion and reproduction of headache with neck movement or pressure, in diagnosing cervicogenic headaches 5. Given the most recent and highest quality evidence, the use of MRI for cervicogenic headache diagnosis is supported by its ability to accurately visualize the cervical spine and its components, thereby aiding in the differentiation from tension headaches 1.
