Abstract:
OBJECTIVE To investigate the carotid artery invasion in patients with head and neck malignant tumor with multislice helical CT and MPR. METHODS Thirty-six tumors adjacent to the carotid artery in head and neck were studied using 16 slice helical CT scanner.The following two parameters were measured:tumor-artery angle(the angle surrounded by the tumor)and tumor-artery ratio(the ratio between the length of intersection of the tumor with carotid and the diameter of the carotid).RESULTS Tumor-artery angle:in judgment of carotid involvement with axial CT,the accuracy of the tumor-artery angle≥90?group and the tumor-artery angle≥180?group were higher than that of the tumor-artery angle≥45?group (P
