Xenon CT measurement of cerebral blood flow in hydrocephalus. 1995

Since the recognition of normal-pressure hydrocephalus as an entity (1965), ventriculo-atrial or peritoneal shunting has been proposed as a treatment for this disease. Unfortunately, selection of patients who would benefit from shunting has always been difficult, and no clinical or brain imaging criteria have been entirely satisfactory. Functional studies intended to measure the local cerebral blood flow (lCBF) seem more promising. Xenon CT CBF measurement has been chosen because of its ability to measure deep white matter lCBF with good spatial resolution. This preliminary study reports the results of lCBF measurement in four patients examined by this technique before and after shunting or cerebrospinal fluid subtraction by lumbar puncture. In this small collective the two patients who improved clinically after shunting or lumbar puncture also had a substantial improvement in deep white matter lCBF.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D002540	Cerebral Cortex	The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D002557	Cerebrospinal Fluid Shunts	Tubes inserted to create communication between a cerebral ventricle and the internal jugular vein. Their emplacement permits draining of cerebrospinal fluid for relief of hydrocephalus or other condition leading to fluid accumulation in the ventricles.
