CT Hounsfield Unit Is a Good Predictor of Growth in Meningiomas

Neurologia medico-chirurgica, 2019
Predicting the growth rate of meningiomas is important in treatment planning. Although calcification may be an important sign of slow growth in meningiomas, the developmental process and its relation to the tumor growth pattern have not been elucidated.
