“…El Backry et al 17 studied the role of DCE‐MRI in differentiating benign from malignant head and neck neoplasms with a sample size of 55 patients wherein they found 82% of the benign tumors showing gradual progressing and plateau curves, whereas 93% of malignant tumors displayed plateau and fast curves. Among the evaluated perfusion parameters, wash‐in rate with a cutoff value of 15.4/s (sensitivity: 87.9%, specificity: 90.0%) was adjudged as the best parameter for differentiating benign from malignant tumors.…”

“…A total of 55 patients with head and neck masses were evaluated by Backry et al 10 Four TIC patterns were described: Type A (gradual enhancement), type B (rapid enhancement and low washout), type C (rapid enhancement and fast washout), and type D (flat). It was found that most of the benign tumors showed type A curve while malignant tumors showed type C curve while curve B and D were statistically insignificant.…”

“…Moreover, to date only 11 cases have been reported regarding the apparent diffusion coefficient (ADC) values of STA 10,12 . Only one study used quantitative dynamic contrast‐enhanced MRI (DCE‐MRI) parameters with STA but in a small percentage of included cases (3/55, 5.5%) 13 . No reports focused on only STA.…”
