In echography, ultrasound waves pass through the cranial cavity and are reflected from the midline structures of the brain, which most authors refer to as the epiphysis, the third ventricle, the sickle-shaped process, the longitudinal interhemispheric cleft, and the transparent septum. This is the so-called midline echo - M-echo.</p>Kazan Medical archiveКазанский медицинский архив
