Abstract

The invention is applicable to the technical field of magnetic resonance imaging, and provides a method, a device, equipment and a medium for inhibiting cerebrospinal fluid signals in vessel wall imaging. The method comprises the following steps of: in a magnetic resonance vessel wall imaging process, reversing a obtained longitudinal macroscopic magnetization vector to a XY plane through a firstangle reversal pulse and a second angle reversal pulse in a preset reversal recovery pulse chain, thereby obtaining a transverse magnetization vector; reversing the transverse magnetization vector toa negative Z axis, thereby inhibiting the cerebrospinal fluid signals. The effect of inhibiting the cerebrospinal fluid signals in the magnetic resonance vessel wall imaging is improved, the tissue contrast of the vessel wall image is improved, and the diagnosis and quantitative analysis of the doctor is facilitated.

Description

technical field [0001] The invention belongs to the technical field of magnetic resonance imaging, and in particular relates to a method, device, equipment and medium for suppressing cerebrospinal fluid signals in blood vessel wall imaging. Background technique [0002] Cardiovascular and cerebrovascular diseases have become the primary disease that threatens human health, and atherosclerotic plaque is an important risk factor leading to the occurrence of cardiovascular and cerebrovascular diseases. Stroke events are of great significance. Since intracranial arteries are surrounded by cerebrospinal fluid, in order to clearly distinguish the boundaries of the intracranial artery wall and the plaque attached to it, it is necessary to simultaneously suppress arterial blood flow and cerebrospinal fluid signals. At present, Delays Alternating with Nutation for Tailored Excitation (DANTE) can effectively suppress arterial blood flow and cerebrospinal fluid signals. This technolog...
