Gammagrafia de la perfusión cerebral en neurología y neurocirugía

Oncología, 2019
Aunque el cerebro constituye el 2-3% del peso total corporal, sin embargo requiere del 20% del consumo total de oxígeno y del 15% del gasto cardiaco, habiéndose estimado que la corteza cerebral normal presenta un flujo sanguíneo promedio de 50-55 ml/min
