Embodiment 1

[0041] The magnetic resonance imaging method provided by the present invention applies imaging sequences periodically, and the number of repetitions of the period is not less than 1, such as figure 1 As shown, in each cycle, steps are included:

[0042] S100, applying a 180° radio frequency pulse;

[0043] S200, applying a gradient echo sequence;

[0044] S300. Apply a first fast spin echo sequence.

[0045] A T1-weighted image is generated from the data acquired in the gradient echo sequence, and a CSF-suppressed T2-weighted image is generated from the data acquired in the first fast spin echo sequence. Specifically, as figure 2 As shown, the magnetic resonance imaging equipment periodically applies an imaging sequence, and each cycle of the imaging sequence includes a reversal recovery module, a T1-weighted imaging module, and a T2-weighted module for cerebrospinal fluid suppression. The sequence diagram of each module is shown in Figure 4-6 As shown, the sequence of e...

Embodiment 2

[0060] Based on the above embodiments, the present invention also provides a magnetic resonance imaging device, the block diagram of which can be as follows Figure 8 shown. The device includes a processor 10 and a memory 20 . Understandably, Figure 8 Only some components of the terminal are shown, but it should be understood that implementation of all illustrated components is not required, and more or fewer components may be implemented instead.

[0061] The storage 20 may be an internal storage unit of the terminal in some embodiments, such as a hard disk or memory of the terminal. The memory 20 may also be an external storage device of the terminal in other embodiments, such as a plug-in hard disk equipped on the terminal, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD ) card, flash memory card (Flash Card), etc. Further, the memory 20 may also include both an internal storage unit of the terminal and an external storage device. The...

Abstract

The invention discloses a magnetic resonance imaging method, equipment and storage medium. The method includes: in each cycle: applying a 180° radio frequency pulse; applying a gradient echo sequence; applying a first fast spin echo sequence; wherein, the repetition times of the cycle is not less than 1; collecting according to the gradient echo sequence A T1-weighted image is generated from the data of the first fast spin echo sequence, and a CSF-suppressed T2-weighted image is generated from the data acquired in the first fast spin echo sequence. The present invention takes advantage of the gap between the inversion recovery pulse and the excitation pulse needed to generate CSF-suppressed T2-weighted images by applying a gradient echo sequence after applying the 180° RF pulse and before applying the first fast spin echo sequence. time to acquire T1-weighted image data, shortening the MRI scan time to generate T1-weighted images and CSF-suppressed T2-weighted images.

Description

technical field [0001] The present invention relates to the field of magnetic resonance technology, in particular to a magnetic resonance imaging method, equipment and storage medium. Background technique [0002] Clinically, magnetic resonance sequences are often used to scan and image lesions. For some diseases, such as TSC (Tuberous Sclerosis Complex, Tuberous Sclerosis Complex), a clearer display is required. In order to clearly display lesions, the selected clinical scanning The intra-layer resolution is high, and the amount of data to be collected is large, resulting in a longer scanning time, and a longer scanning time will cause discomfort to the patient. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [0004] In view of the above-mentioned defects of the prior art, a magnetic resonance imaging method, device and storage medium are provided, aiming at solving the problem of long scanning time of the magnetic re...
