CT diagnosis is generally plain CT, enhanced CT and cisternography CT.

CT plain scan is generally a cross-sectional scan, which takes the auditory canthus line as the baseline and scans up or down in turn. The contrast agent commonly used in enhanced CT scanning is 60% meglumine diatrizoate, which is 1.5~2.0ml per kg body weight. Anyone with allergic history and heart and renal failure is prohibited from using 60% meglumine diatrizoate.

Cerebral cisternography CT usually injects nonionic contrast agent or gas through lumbar puncture or cisterna magna puncture to fill the cisterna.
