Method for saving time of MRI contrast agent extraction

Abstract

The invention relates to a method for saving time of MRI contrast agent extraction. The method is characterized by comprising the following steps: (1) preparing at least one injector, extracting the contrast agent by using the injector before MRI check and putting the injector which is full of the contrast agent in a refrigeration device for after use; (2) when the MRI check is carried out, taking one injector which is full of the contrast agent from the refrigeration device and injecting the contrast agent into the body of a patient; (3) carrying out MRI scanning on the patient. According to the method for saving time MRI contrast agent extraction, the enhanced contrast agent can be uniformly extracted before the MRI check and put in a refrigerator for after use, so that the step of extracting contrast agent before the enhancement scanning of each patient is avoided and the time is saved. The method is cost-saving and very practical.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to MRI scanning, and specifically refers to a method for saving time for pumping MRI contrast agents. Background technique [0002] Magnetic resonance imaging is a type of tomography, which uses magnetic resonance phenomena to obtain electromagnetic signals from the human body and reconstruct human body information. In 1946, Flelix Bloch of Stanford University and Edward Purcell of Harvard University independently discovered the phenomenon of nuclear magnetic resonance. Magnetic resonance imaging is based on this physical phenomenon. In 1972, Paul Lauterbur developed a method for spatial encoding of nuclear magnetic resonance signals, which can reconstruct human body images. MRI magnetic resonance imaging technology has something in common with other tomographic imaging technologies (such as CT), for example, they can both display the distribution of a certain physical quantity (suc...

Problems solved by technology

[0004] However, due to the long time of MRI examination and the limited capacity of the high-pressure injector, the number of MRI examinations that can be performed every day is limited. As a result, patients need to make an appointment for several days for MRI examination, which may delay the patient's consultation time.

Moreover, in MRI-enhanced patients, in order to save costs, if a high-pressure injector is not used, the contrast agent is usually pumped on-site before the enhanced scan, and then manually injected. This step takes a certain amount of time for each patient.
