Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] figure 1 It is a schematic flowchart of a deep vein thrombosis magnetic resonance imaging method in one embodiment. Such as figure 1 As shown, the magnetic resonance imaging method includes the following steps:

[0024] In step S110, the blood flow signal of the deep vein is suppressed to obtain a preprocessed signal including the deep vein vessel wall signal and the thrombus signal.

[0025] Deep vein thrombosis refers to abnormal clotting of blood in deep veins, blocking the lumen caused by venous reflux disorders. The commonly used deep vein thrombosis detection method uses magnetic r...

Abstract

The invention relates to a deep-venous-thrombosis magnetic resonance imaging method and device, a medium and computer equipment. The method includes the steps that blood flow signals of deep veins areinhibited, and preprocessing signals comprising deep-vein vessel wall signals and thrombosis signals are obtained; the preprocessing signals are sampled with water-excitation-pulse three-dimensionalgradient echo sequences; according to the sampled data, a deep-venous-thrombosis magnetic resonance image is obtained. According to the deep-venous-thrombosis magnetic resonance imaging method and device, the medium and the computer equipment, the preprocessing signals are sampled with the three-dimensional gradient echo sequences, and the sampling period can be effectively shortened; the samplingsequences are excited with the water-excitation pulses, fat signal inhibition is achieved while imaging signals can be excited, artifacts generated by uneven fat inhibition are reduced, and thereforethe accuracy of thrombosis detection is improved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a deep vein thrombosis magnetic resonance imaging method, device, medium and computer equipment. Background technique [0002] There are four main types of imaging techniques currently available for the examination of deep vein thrombosis (DVT) in the lower extremities, including digital subtraction angiography (Digital Subtraction Angiography, DSA), ultrasound (Ultrasound, US), computed tomography (Computed Tomography) , CT) and Magnetic Resonance Imaging (MRI). Among these four types of methods, magnetic resonance has been gradually applied to clinical examination of DVT due to its many advantages such as good soft tissue contrast, multi-parameter scanning, full-field imaging, and no radiation damage. However, the existing technology still has major limitations. [0003] Traditional magnetic resonance vessel wall imaging methods for clinical examination and diagnosis o...
