Abstract：Objective To explore the effect of optimizing nasopharyngeal and cervical magnetic resonance imaging (MRI) combined with enhanced T1 weighted imaging fat suppression (T1WI FS) serial scanning technology on image quality in patients with nasopharyngeal carcinoma. Methods A retrospective analysis of 60 cases of nasopharyngeal carcinoma patients (A group) combined plain scan and enhanced scan image quality, to evaluate its impact on the observation results of tissue structure, and then optimize and verify the scan sequence or sequence according to the source of the problem that affects the image quality. Finally, the chi-square test and Fisher exact probability method were used to analyze the difference in image quality and organization structure improvement of 60 cases (B group) before and after sequence optimization. Results 58 cases in A group and 57 cases in B group were included in the analysis. There were no clear image quality problems in A group and B group before optimization. The main problem of image quality in A group and B group before optimization was the magnetic sensitivity of T1WI FS sequence. Magnetic sensitive artifact (MSA), vascular pulsation artifact (VPA) and non-uniformity fat suppression (NUFS)| 57 cases of MSA, VPA and NUFS in B group were signi?cantly improved after optimization, P values were all <0.001. Conclusion Nasopharyngeal and neck MRI combined with T1WI FS scans mostly have problems such as MSA, VPA and NUFS, which can be reduced or eliminated by optimizing the scan sequence or sequence parameters, and the diagnostic accuracy or diagnostic con?dence can be improved.
