ABSTRACT To analyze and evaluate the MR diffusion-weighted imaging (MR-DWI) features of head and neck hemangioma and venous malformation in children.
We retrospectively observed 10 head and neck hemangiomas and 40 head and neck venous malformations in children, which underwent both conventional MR imaging and MR-DWI. In the MR-DW images, the apparent diffusion coefficient(ADC) mean value was taken from b=500 s/mm² and 1000 s/mm², The data was analyzed using SPSS13.0 software package for t test.
The mean ADC obtained from b value of 500 s/mm² was (1.227±0.324)x10⁻³mm²/s in hemangioma and (1.851±0.364)x10⁻³mm²/s in venous malformation, and from b value of 1000 s/mm² was (0.728±0.256)x10⁻³mm²/s in hemangioma and (1.200±0.228)x10⁻³mm²/s in vein malformation. There was significant difference between both lesions (P<0.01).
There are different features in MR-DWI between head and neck hemangioma and venous malformation in children, which may be helpful for radiological differential diagnosis.
