Does our human & experienced Radiologist Eye see
"brain atrophy"
on rutinary CT or MRI images?
If answer is "Yes" our Neurologists or Geriatricians decide to treat the patient medically
If answer is "No" or "Not sure" we continue with a specific MRI study & Postprocessing Structural Brain Mapping
We only consider selected patients clinically diagnosed of
Mild Cognitive Impairment
by Neurologists and/or Geriatricians & Neuropchycologists
Simple rutinary CT and/or MRI study?
MRI images with specific acquisition and complex long Postprocessing Parametric Mapping using Computer tools to avoid interobserver variability?
We can determine our patient's neuron loss evolution comparing to himself & to normal population
We diagnose and treat Alzheimer's Disease before Clinical or Traditional CT/MRI Evidence
CONCLUSIONS:
Thank you!
