We evaluated the usefulness of simple diffusion kurtosis (SD) imaging, which was devel-oped to generate diffusion kurtosis images simultaneously with an apparent diffusion coefficient(ADC) map for 27 cystic disease lesions in the head and neck region. The mean kurtosis (MK)and ADC values were calculated for the cystic space. The MK values were dentigerous cyst (DC):0.74, odontogenic keratocyst (OKC): 0.86, ranula (R): 0.13, and mucous cyst (M): 0, and the ADCvalues were DC: 1364 × 10−6 mm2/s, OKC: 925 × 10−6 mm2/s, R: 2718 × 10−6 mm2/s, and M:2686 × 10−6 mm2/s. The MK values of DC and OKC were significantly higher than those of R andM, whereas their ADC values were significantly lower. One reason for the characteristic signal valuesin diffusion-weighted images of DC may be related to content components such as fibrous tissueand exudate cells. When imaging cystic disease in the head and neck region using SD imaging, themaximum b-value setting at the time of imaging should be limited to approximately 1200 s/mm2for accurate MK value calculation. This study is the first to show that the MK values of DC arecharacteristically higher than those of other cysts.
