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, such 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...
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. In other embodiments, the memory 20 may also be an external storage device of the terminal, 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. Th...
Embodiment 3
[0064] The present invention also provides a storage medium, where one or more programs are stored in the storage medium, and the one or more programs can be executed by one or more processors, so as to realize the steps of the magnetic resonance imaging method described in the above-mentioned embodiments .
