Abstract:
Purpose: To study the best MR sequence for liver examination. Methods: Scanning 29 patient's liver with four sequence (SEMSH, Tse
11, Tse
23),measure and calculate Ihe SNR and CNRmeanwhile evaluate the images with vision. Results: The first-string film ratio of FLASH and Tse
23 aresuperior to that of SE and Tse
11 sequence; On T
1 weighted images, the SNR and CNR of FLASH is superiorto that of SE sequence,on T
2 weighted images, the SNR and CNR of Tse
23 is lower than Tse
11 saquence.Conclusion : The FLASH sequence is the first choice for liver MR examination and the Tse
23 sequence canassist it to get more information.
