本研究针对心脏扩散张量成像（cDTI）中回波平面成像（EPI）读码导致的图像失真问题，由研究人员系统评估了FSL TOPUP与TORTOISE DR-BUDDI两种校正技术。结果表明，TOPUP在几何保真度（DSC=0.86, AHD=1.33 mm）和参数稳定性（MD=1.64 μm2/ms, FA=0.26）方面均优于DR-BUDDI，为cDTI精 ...

To do this, they used two cutting-edge heart scanning techniques: cardiac diffusion tensor imaging (cDTI), a type of MRI scan that shows how individual heart muscle cells are organised and packed ...

MRI images of the hearts of a healthy volunteer (left), individual with HCM gene but no symptoms (middle), patient with overt HCM (right). Top: quantitative perfusion images showing defects in heart ...

Anew robotic heart can contract and expand with a remarkably lifelike beat, researchers reported yesterday (January 29) in Science Robotics. The researchers created the robotic heart as a tool to ...
