MCA
n. countablen. Stands for Middle Cerebral Artery. A large blood vessel in the brain that provides blood to the parts that control movement and speech.
n. Abbreviation for Middle Cerebral Artery. One of the three major paired arteries that supply blood to the cerebrum, specifically the lateral surfaces of the frontal, parietal, and temporal lobes.
The doctor checked the blood flow in the patient's MCA.
A blockage in the MCA is a common cause of stroke and can lead to sudden weakness on one side of the body.
Radiologists often use Doppler ultrasound to measure the velocity of blood flow through the MCA to assess the risk of vasospasm following a subarachnoid hemorrhage.
Typically used as a singular countable noun in clinical reports; often preceded by the definite article 'the'.
