Abstract:

Cerebrovascular disease is the disease with the highest mortality and disability rate in China. Digital subtraction angiography, CT angiography, magnetic resonance angiography, and other traditional imaging technologies can only show the degree of stenosis of the lumen, but can not show the early changes of the vascular wall. High resolution magnetic resonance vascular wall imaging (HR-VWI) is a new technique for displaying vascular diseases, which can clearly display the vascular wall and has good application value for early diagnosis and prediction of cerebrovascular diseases. This article compared and analyzed the techniques for HR-VWI, such as spatial pre-saturation technology, double inversion recovery technology, motion-sensitized driven equilibrium technology, delay alternating with nutation for tailored excitation technology, and variable flip angle fast/turbo spin-echo. It is helpful to develop a clinical scanning strategy for vascular diseases.
