Abstract:
OBJECTIVE:To investigate the value of MRI and MSCT in TNM staging of laryngocarcinoma.
METHOD:Thirty-seven patients with laryngocarcinoma were underwent by contrast enhanced scan and multiplanar reconstruction. Thirty-five patients with laryngocarcinoma were underwent contrast enhanced multislice spiral CT, which of them were done by MPR. There are 28 cases which were scan by MRI and MSCT in the two former and we contrasted the accuracy rating in laryngeal manifestation of abnormality. In the former two groups, we observed them the variability in the aspect of lymphaden metastasis and TNM staging.
RESULT:In all 28 cases, the MRI had better accuracy rating in displaying the parts of preepiglottic space, larynx side interspace, lingual root, neck tissue, vocal cord. In the TNM staging, there was no difference in stage one in accuracy rating, as the stag stepping up, the accuracy rating of MRI had became better. The last result was that the two methods had difference in staging. In the two methods, MSCT had better sensitivity, specificity and accuracy rating.
CONCLUSION:MRI and MSCT had good accuracy rating in TNM staging, MRI has better accuracy rating in some of laryngeal, but as the lymphaden metastasis, the MSCT was better. There were variability in staging, and the MRI was better.
