    Midline shift (MLS) of the brain is an important feature that can be known that intracranial mass can cause brain shift, followed by herniation.
    A number of studies have examined the effects of midline shift on long-term outcomes. Colorado Springs, Colorado. The authors have sought to confirm the correlation of pineal shift with level of consciousness and to assess the prognostic value of brain shift measurements in a prospective study.

    Also, it lessens the chance of human error by detecting MLS from an entire image set compared to selecting the single most important slice, which allows the computer to do the work that was once manually done. Namespaces Article Talk. However, new-generation CT scanning picks up most cases of SAH noninvasively, so the best approach is to obtain a CT scan first and follow with LP if the scan result is negative.

    Midline shift is the degree of horizontal shift of midline cerebral structures as risk of developing tentorial herniation than those with a frontal or parieto-occipital​.
    The sign can be caused by conditions including traumatic brain injury, ischemic strokeintracranial hematomaor birth deformity that leads to a raised intracranial pressure. A midline shift occurs when the pressure exerted by the buildup of blood and swelling around the damaged brain tissues is powerful enough to push the entire brain off-center.
