Scans and Tests

CT scans

A CT scan is a computerized tomography scan of your head. Doctors conduct

this scan through X-rays and try to locate any untoward growth, swelling, or
inflammation that could be the cause of your headache. This test can divulge

details of sinus problems, strokes, and tumors.

MRI scans

An MRI scan is a scan through Magnetic Resonance Imaging. This is a diagnostic

procedure to form images of your inner body parts and organs through a

combination of radio waves, computer technology, and a strong magnetic field.
You lie on a table while the detectors take measurements of your head from
various angles. Different computer processes form three-dimensional pictures of

your brain and head.

An MRI is a costlier procedure but delivers detailed revelations. MRI scans are

without iodine or contrast dye. You get to know of any sinus problems, malignant
diseases, skull fractures, concussions or other serious medical problems.

Lumbar Puncture or Spinal Tap

Sometimes doctors take some fluid from your lumbar region for testing about
your headaches. This test detects any brain diseases like subarachnoid

hemorrhage or meningitis. Tests of a sample of the cerebrospinal fluid (CSF) can
detect any such disease. You could develop a headache after this test as drawing

of fluid upsets your CSF pressure. This test carries the risk of infection too. The
test lasts for around half an hour.

Sinus X-Ray

This can detect and provide a clearer picture if you have any sinus-related
problems where your headache could be an aftermath of such infection.
