Brain CT MRI Distinguish

Head ct and magnetic resonance imaging are two different examinations. Head ct is superior to magnetic resonance imaging in the early diagnosis of craniocerebral trauma and cerebral hemorrhage. But magnetic resonance imaging is obviously superior to head ct in the early diagnosis of ischemic cerebrovascular disease, that is, cerebral infarction. It is also obviously superior to head ct in neurodegenerative diseases and demyelinating diseases. Head ct examination time is relatively short, generally no more than 5 minutes. There is no special selectivity for patients examined, and this examination can generally be carried out. Head MRI examination time is longer, generally more than 15 minutes, and patients with metal implanted in the body are not eligible for head MRI examination.
