The examination checks the flow of cerebrospinal fluid flow through the Sylvian aqueduct.
A normal brain produces about half a litre of cerebrospinal fluid in 24 hours. Normally the equilibrium in the rates of production and resorption of the fluid is maintained. If the balance is disturbed due to reduced production or some pathological stenosis, hydrocephalus occurs.
The flow study is performed with special techniques using an MRI tomography machine, which is part of the fully renewed equipment of PLATON DIAGNOSIS. The machine contains new technology a 32 channel brain coil providing top quality images.
The examination is performed using the perspective/prospective resonance method. In other words, data collection takes place during a heart cycle and stops when the cycle ends until the next activation signal comes. This produces a set of images that are reconstructed at the sagittal plane. The sequence is made up of 1-5mm slices so that they cover the aqueduct diameter, which ranges from 2 to 4 mm.
