Cerebral hemorrhage is a serious threat to human health.

Cerebral hemorrhage is a serious threat to human health.

With the continuous development of MRI technology, MRI examination has gradually been widely used in the clinical diagnosis of acute cerebral hemorrhage , which has the advantages of clear positioning and qualitativeness

The general evolution of MRI signal of intracerebral hematoma:

In general, intracerebral hematoma can be divided into hyperacute phase, acute phase, subacute early stage, subacute middle stage, subacute late stage, and chronic stage

In general, intracerebral hematoma can be divided into hyperacute phase, acute phase, subacute early stage, subacute middle stage, subacute late stage, and chronic stage

(1) The hyperacute period (1) The hyperacute period refers to the moment when the blood leaks, and the leaked blood has not yet coagulated

The evolution of cerebral hemorrhage is a complicated process.

Note: The stages of MRI signal changes of cerebral hemorrhage do not have strict boundaries, but are continuous changes.

The knowledge of this table assists learning.
The blood is constantly evolving according to the evolution of tissue time and whether the peripheral blood vessels are connected or not, and it needs to be used flexibly
