Objective of 104 patients with NPC (nasopharyngeal carcinoma, NPC) CT (computerized tomography) and MRI (magnetic resonance imaging) data were analyzed to explore the '08 installment, '92 Fuzhou staging and '02 the UICC / AJCC (International Union Against Cancer / American Joint Committee on Cancer) staging of nasopharyngeal T staging. Materials and Methods From January 2009 to 6 pathologically confirmed 104 cases of untreated NPC patients before treatment interval the the week expert nasopharyngeal and neck-enhanced CT and MRI. CT scan: GE8 slice CT scanners scan the supine position, scan range from the sternoclavicular joint to the suprasellar cistern, slice thickness 5mm, all patients underwent axial enhanced scan, partial demolition as thin as 2.5mm, spread to GE Advantage Worksation 4.2 post-processing workstation line multi-planar reconstruction (inclined plane, sagittal, coronal, and curved). MRI scans: GE Signa 1.5 T superconducting magnetic resonance imager, using the head coil, thickness 6mm layer spacing 1mm; imaging sequences: Axial T1 fast spin echo (Axial T1 FSE), sagittal T1 fast since the cycle wave (Sagital T1 FSE), Axial T2 fat-suppressed fast spin-echo (Axial FSE T2fs) or proton density fat-suppressed spin-echo (Axial PD fs) coronal short T1 inversion recovery (Coronal STIR), transection Coronal T1 fast spin-echo fat-suppressed enhanced fat-suppressed T1 fast spin echo enhanced (the Axial T1 FSEfs Gd) scanning (Coronal T1 FSEfs Gd) six sequences; Scan range: more than two imaging sequence coverage from the temporal lobe Central to the thoracic inlet; scanning plane: Coronal 3 cervical parallel, axial 3 cervical vertical. And CT and MRI results (especially of the skull base invasion) were analyzed, all the data are used SPSS13.0 statistical software for processing. 104 NPC patients MRI showed the slopes, sphenoid body, inside and outside the pterygoid side panels, petrous apex and cavernous sinus invasion was significantly better than CT, MRI skull base invasion detected in the number of cases of 65 cases (62.5%), CT skull base invasion detected cases of 30 cases (28.8%) ratio, both significant difference, p lt; 0.05 (χ 2 value of 23.735). 104 NPC patients in Fuzhou, '92, '08 installments staging T Dividing T 2 , T 3 phase as well as the overall distribution, have a statistically significant difference , p lt; 0.05 (χ 2 value of 11.493). 104 NPC patients installments '08 with '02UICC / AJCC staging T stage divided in T2, T 3 , T 4 period and overall distribution has statistically significant difference, p lt; 0.05 (χ 2 value of 15.887). Conclusions based on MRI of '08 staging systems representing T staging of NPC, late the '92 Fuzhou installments and '02UICC / AJCC staging system, T stage, the difference will be the development of NPC treatment program and its prognosis have an important impact. Prospective study of new treatment technology development in view of the new staging system adapted to its comparison with the old staging system should have a higher clinical value, of course, its long-term effects still need a multi-center, large cases and long-term follow-up to be confirmed.
