Why do patients with dizziness need to undergo imaging examinations?

Generally speaking, the main reasons for conducting imaging examinations for patients with dizziness include ruling out cerebral vascular abnormalities, identifying cervical spine structural issues, diagnosing intracranial inflammation, detecting space-occupying brain lesions, and assessing bony abnormalities related to the inner ear. If discomfort symptoms arise, it is recommended to seek timely medical consultation and treatment at a reputable hospital. Detailed explanations are as follows:

1. Ruling out Cerebral Vascular Abnormalities

Cerebrovascular abnormalities, such as cerebral vascular stenosis or cerebral infarction, may impair cerebral blood supply, leading to vestibular system ischemia and causing dizziness. Imaging examinations can clearly reveal the status of cerebral vessels and provide a basis for treatment.

2. Identifying Cervical Spine Structural Issues

Conditions such as cervical osteophytes or intervertebral disc herniation may compress the vertebral artery or nerve roots, affecting cerebral blood supply and causing dizziness. Imaging tests can clearly reveal cervical structural abnormalities. In daily life, one should avoid prolonged periods of neck flexion and perform appropriate cervical traction exercises.

3. Diagnosing Intracranial Inflammation

Intracranial inflammations, such as viral encephalitis or purulent meningitis, can damage the vestibular center or related nerves, resulting in dizziness. Imaging examinations can assist in determining the extent and severity of the inflammation.

4. Detecting Space-Occupying Brain Lesions

Benign space-occupying lesions in the brain, such as meningiomas or acoustic neuromas, may compress the vestibular nerve or brain tissue, causing dizziness. Imaging examinations can precisely determine the location and size of the lesion.

5. Assessing Bony Abnormalities Related to the Inner Ear

Bony structural abnormalities in the inner ear, such as otosclerosis, may impair inner ear function and cause dizziness. Imaging examinations can help identify these bony abnormalities.

In daily life, it is important to avoid sudden, vigorous head movements to prevent worsening of dizziness; ensure adequate sleep and avoid excessive fatigue; perform appropriate balance training, such as walking slowly or practicing yoga; and schedule regular follow-up visits to adjust treatment plans according to disease progression.
