Embodiments can relate to a method for detecting a physiological condition by generating a Magnetic Resonance Image (MRI) contrast image comprising a T1 weighted (T1W) image/T2 weighted (T2W) ratio. Embodiments can further include using the T1W/T2W ratio to identify changes in substantia nigra pars compacta within a region of the brain.
