Feasibility study of diusion weighted imaging of nasopharynx using split-echo TSE-DWI combined with MultiVane acquisition

Diusion weighted imaging (DWI) has high sensitivity in the dierential diagnosis of nasopharyngeal carcinoma. However,the DWI based on SE-EPI has poor imaging quality in the nasopharynx. A combination of Multi-Vane (MV) and SPLICE(MV-SPLICE) were developed to reduce ELT, as well as improve SNR and the imaging quality of DWI. This study compares theDWI images of three acquisition sequences in nasopharynx,including DWI TSE without SPLICE(TSE), TSE with SPLICE(TSE-XD), and TSE with MV-SPICE(TSE-XD-MV) and proves that TSE with MV-SPLICE DWI based TSE with MV-SPLICE provides anexcellence imaging scheme of DWI for the clinical diagnosis of nasopharyngeal diseases.
