We proposed an automatic evaluation model for estimating the degree of motion artifacts in high-resolution multi-echo gradient echo images for nigrosome-1 visualization in the substantia nigra. A combination of a convolutional neural network and a long short-term memory was used to develop the automatic motion evaluation model. The results demonstrated that the proposed model could be useful tools for N1 visualization for diagnosing Parkinson’s disease.
