Ultra-fast enhancement ultrasound monitors blood supply at spinal cord injury site

Ref: Khaing ZZ, et alJNeurosurg Spine2018 Sep;29 (3): 306-313doi: 10.3171/2018.1.SPINE171202Epub 2018 Jun 15.)ischemic semi-dark band in the injured area of traumatic spinal cord injury (traumatic spinal cord injury, tSCI) and the presence of secondary low perfusion zones near the injuryAt present, neuroprotective therapy is to limit the above-mentioned secondary injury, but during surgery to detect the blood flow time distribution and spatial distribution of the injured spinal cord is more difficultZin ZKhaing of Neurosurgery at the University of Washington in Seattle, USA, and others used enhanced ultrasound ultrasound doppler( CEUS Doppler) to detect local hemodynamic changes in rodent spinal cord injury models, published online in June 2018 in Js Neurourg Spineresearchers used iris to build a model of chest damage in adult ratsAt the same time, using a new type of overspeed CEUS Doppler instrument made of an ultrasonic platform combined with a 15MHz linear array transducer, the low-speed blood flow of high-speed blood flow in the blood vessels and tissue perfusion microcirculation is collected through ultra-fast flat wavesLocal blood flow changes are shown immediately after the booster is injectedThe results showed that the ultrasound images of the animal model of chest marrow injury can be monitored in real time to the bloodless perfusion area of 1.93 to 1.14mm2, and the low perfusion area of 2.21 to 0.6mm2, i.eischemia semi-dark band, with a significant difference between the two in real time (Figure 1)Figure 1Blood flow is infused with topographic maps after spinal cord injury Red indicates no blood flow perfusion area, blue indicates low blood flow perfusion area, green indicates normal blood flow perfusion area the study, ultra-fast-enhanced ultrasound Doppler helps monitor spinal cord blood supply in real time, laying the experimental foundation for further exploration of the treatment of "salvageable" semi-dark areas of the spinal cord (Fudan University, Shanghai School of Medicine
