The initial, horizontal segment of the middle cerebral artery.

A sophisticated imaging technique using magnetic fields instead of x-rays to create the image.

Middle cerebral artery

Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes.  A genetic disorder of mitochondria occurring in children and adults and associated with neurologic deficits.

Muscle Evoked Potential. Refers to a recorded nerve or muscle potential that is evoked by stimulation of the central nervous system, typically transcranial cortical stimulation. The D-Wave refers to the recorded upper motor neuron potential and the muscle MEP refers to the potential recorded from a muscle.

Maternal-Fetal Medicine: a subspecialty of obstetrical medicine that specializes in the care of women with complicated or high-risk pregnancies.

O-6-methylguanine-DNA methyltransferase-an enzyme that repairs DNA damage due to methylation. The gene responsible for the synthesis of this enzyme is variably expressed and tumors with epigenetic silencing of this gene have been found to be particularly sensitive to the drug temozolomide.

as in MIB-1 antibody – a monoclonal antibody used to determine the Ki-67 labeling index, an indicator of the degree of cell proliferation shown on a histological section (microscopic piece of tissue being examined microscopically). It can be used on formalin-fixed paraffin-embedded sections, a process used universally when examining submitted material microscopically.

a sonography-based imaging technique with a higher resolution than conventual millimeter scale doppler ultrasound with an ability to image to a depth exceeding the 5 cm limit of conventional ultrasound imaging.  This technology allows for a much more detailed image of vascular structures and their directionality of flow.
