Online published on 4 April, 2020. Abstract Purpose Assessing DW MR imaging and ADC value in pediatric head and neck lesions and ability of determination benign from malignant masses. Methods Study was undertaken on 56 patients as 39: 17, male: female, respectively where they had head or neck mass. Patients exposed to routine MRI to characterize lesions. Diffusion weighted imaging sequence was added to routine MR and evaluation of DWIs. Results We found that ± ADC of malignant, benign lesions as0.64 X 10−3, 1.58 X 10−3, and 2.10 X 10−3 mm2/sec. ADC of 1.25 X 10−3 mm2/sec threshold value was used to differentiating among tumors which were represented 100% and 94.1% for sensitivity and specificity, respectively. Conclusion Beneficial roles for DW imaging to discriminate between malignant and benign head and neck tumors. Top Keywords Diffusion MR imaging, pediatric head and neck masses. Top |
