Embodiment

[0030] The invention provides a method for controlling enhanced nuclear magnetic resonance imaging, comprising the following steps:

[0031] S1. Pre-scanning with nuclear magnetic resonance equipment to obtain multiple tomographic images of the coronal plane;

[0032] S2. Find the superior vena cava 4 and the aorta 5 in multiple tomographic images; the superior vena cava 4 is in the first tomographic image, and the aorta 5 is in the second tomographic image;

[0033] S3. Connect any point of the superior vena cava 4 in the first tomographic image with any point of the aorta 5 in the second tomographic image to obtain an oblique tomographic straight line;

[0034] S4. Make a cross-section perpendicular to the axial plane through the oblique fault line, and use the cross-section as the reference plane 8 for nuclear magnetic resonance imaging;

[0035] S5. Carry out scanning imaging on the reference plane 8; inject the contrast agent, and monitor the moving track of the contrast...

Abstract

The invention provides a method for controlling enhanced nuclear magnetic resonance imaging. The method comprises the following steps: S1, performing pre-scanning to obtain a plurality of tomography images of a coronal plane; S2, respectively finding a superior vena cava and an aorta in the tomography images, wherein the superior vena cava is in a first tomography image and the aorta is in a second tomography image; S3, connecting any point of the superior vena cava in the first tomography image to any point of the aorta in the second tomography image to obtain an oblique tomography line; S4,drawing a section perpendicular to the shaft-shaped surface through the oblique tomography line, and taking the section as a reference surface; S5, performing scanning imaging on the reference surface, injecting a contrast agent, and monitoring the movement track of the contrast agent in the superior vena cava and aorta vessels in the reference surface; S6, when it is monitored that the contrast agent enters the aorta, performing voice prompt; and S7, scanning an area to be imaged to obtain an image of the required part. The method can solve the technical problem that enhancement of nuclear magnetic resonance imaging is affected due to the fact that a patient does not hold breath in time after hearing the voice prompt.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance imaging, in particular to a method for controlling enhanced nuclear magnetic resonance imaging. Background technique [0002] During the MRI examination, for some diseased areas, in order to obtain a clearer image, an enhanced MRI scan is required. An MRI-enhanced scan is an MRI scan after intravenous injection of contrast agent. After the contrast agent is injected into the vein, it is distributed to all parts of the human body along with the blood circulation. The blood supply and supply source of various tissues are different, so the distribution amount, distribution time and clearance speed of the contrast agent are different; thus, in the process of MRI scan In the process, different tissues enhance the signal in different degrees, and images with stronger contrast and clearer can be formed. [0003] During the enhanced MRI scan, in order to obtain a clear image for the a...
