During the medical rescue after Wenchuan earthquake, the Department of Appliances and Materials of West China Hospital took prompt action to ensure the regular operation of hospital devices and facilities. Meanwhile, owing to its specialized superiority of material and appliance purchase as well as the optimized processes for material and appliance supply, the hospital ensured the effective supply of disaster relief materials and efficiently managed the consumption of donated materials. From May 12 to 30, a total of 2 200 000 pieces of medical materials (total value RMB 3 770 000 Yuan) and 220 sets of medical appliance (total value RMB 9 000 000 Yuan) were purchased as part of the immediate medical rescue response to the earthquake.
In recent years, due to the emergence of ultrafast ultrasound imaging technology, the sensitivity of detecting slow and micro blood flow with ultrasound has been dramatically improved, and functional ultrasound imaging (fUSI) has been developed. fUSI is a novel technology for neurological imaging that utilizes neurovascular coupling to detect the functional activity of the central nervous system (CNS) with high spatiotemporal resolution and high sensitivity, which is dynamic, non-invasive or minimally invasive. fUSI fills the gap between functional magnetic resonance imaging (fMRI) and optical imaging with its high accessibility and portability. Moreover, it is compatible with electrophysiological recording and optogenetics. In this paper, we review the developments of fUSI and its applications in neuroimaging. To date, fUSI has been used in various animals ranging from mice to non-human primates, as well as in clinical surgeries and bedside functional brain imaging of neonates. In conclusion, fUSI has great potential in neuroscience research and is expected to become an important tool for neuroscientists, pathologists and pharmacologists.
