Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) are used to obtain morphological imaging data. Functional imaging data, such as the spectrum and blood flow changes are obtained by proton magnetic resonance spectroscopy (1H-MRS) and CT perfusion (CTP). Results show that PD rat models have no characteristic morphological imaging abnormalities, but exist regional cerebral blood flow (CBF) reductions and spectral changes in the striatum.展开更多
