Diagnosis of Low Pressure Headache
A doctor's evaluation Sometimes imaging tests Doctors base the diagnosis of low-pressure headaches on the symptoms and the situation. If people have had a spinal tap, the diagnosis is usually obvious, and testing is rarely needed. If people have not had a spinal tap, imaging tests of the brain, such as magnetic resonance imaging (MRI), may be done. Before the imaging test, a contrast agent is injected into a vein, usually in an arm or a hand. The contrast agent is used to provide greater detail.
