Parkinson’s disease (PD) is a progressive neurodegenerative disorder commonly observed in middle-aged and elderly. Currently, its etiology and pathogenesis are still not completely understood. It is associated with many symptoms that severely affect patients’ health and quality of life. At present, the PD clinical treatment mainly aimed to alleviate symptoms, and both medicinal and surgical treatments have side effects and treatment blind spots. The use of acupuncture for the treatment of PD is relatively widespread, and its safety and efficacy have been gradually accepted by the public and medical professions. However, the efficacy of acupuncture in experimental studies remains controversial. Therefore, this paper reviews imaging studies on the use of acupuncture for the treatment of PD. From the study, it shows that acupuncture can improve the neuronal activity, activate the neuronal activity in damaged brain regions, affect relevant neural networks and brain circulation, improve cerebral metabolism, and cause structural changes in related brain regions. Intuitive and visible imaging studies provide objective bases on the use of acupuncture for the treatment of PD.

Pediatric brain tumors are a type of tumors that are commonly present in children and young adults. With the improvement of treatment, the quality of life, especially the cognitive functioning, is gaining increasingly more attention. Apart from cognitive evaluations, neuroimaging studies begin to play an important part in neurocognitive functioning investigation. In this way, the brain tissue changes caused by tumor variables (including tumor location and tumor size) and treatment variables (including surgery, chemotherapy and radiotherapy) can be detected by neuroimaging. Recent advancement of neuroimaging techniques, such as functional- MRI (fMRI) and diffusion tensor imaging (DTI), made great contributions to understanding cognitive dysfunction and quantifying the effects of tumor variables and treatment variables. In recent years, laminar-fMRI provided a potentially valuable tool for examining the exact origins of neural activity and cognitive function. On the other hand, molecular fMRI might guide diagnosis and treatment of brain disease in the future by using new biomarkers, and DTI can detect white matter changes and obtain some anatomically specific information.
