Cerebral angiography is mainly applicable to the examination of intracranial vascular lesions, and is weak in the diagnosis of infections, which is mainly diagnosed by laboratory tests.
Cerebral angiography, including CT arteriography, is mainly applicable to the examination of aneurysms, cerebral arterial stenosis and other diseases, and the examination mainly reflects whether there is any abnormality in cerebral blood vessel alignment and patency, and has little significance in the diagnosis of infection.
In addition, severe intracranial or systemic infections may cause instability of vital signs or consciousness, which may not ensure the safety of the examination, and is therefore a relative contraindication to the examination.
If a test for infection is needed, laboratory tests are the mainstay. Blood tests such as routine blood tests, C-reactive protein, and calcitoninogen, as well as cerebrospinal fluid tests such as routine cerebrospinal fluid and biochemistry, are available. If a definitive determination of the infectious agent is needed, tests such as viral nucleic acid testing and bacterial culture are also available.
It is recommended that patients suspected of having intracranial infections seek early medical attention and be actively diagnosed and treated under the guidance of a doctor to avoid delays.
