Detection of early ischemia in occlusive and hemorrhagic CVA
Embolization

Explanation

Answer: B - Positron emission tomography detects the relationship between cerebral blood flow, oxygen utilization and extraction in focal areas of ischemia.

Electro encephalogram examines the spontaneous electrical activity of the brain.

Single photon emission tomography (SPECT) is used in detection of early ischemia in occlusive and hemorrhagic CVA.

Embolization is an interventional angiography which plays an important role in neurosurgery.
