What does short t2 signal stand for?

On T2-weighted images, the signal is high, which means that the water content of the lesion is high.

According to the query of 39 Health Network, short T2 signal is a term in magnetic resonance imaging (MRI), which refers to high signal on T2-weighted images and high water content in lesions. Short T2 signal can be normal tissue or pathological tissue. For example, acute cerebral hemorrhage is characterized by low signal at T 1 and high signal at T2. Subacute cerebral hemorrhage showed mixed signal of T 1 and high signal of T2. Chronic cerebral hemorrhage is characterized by high signal intensity of t1t.

It is only one manifestation in MRI images, which needs to be combined with other imaging manifestations and clinical symptoms for comprehensive diagnosis.
