Recently DW-MR Imaging has shown promising results in distinguishing between recurrent tumors and posttreatment changes in Head and Neck Squamous Cell Carcinoma (HNSSC).
Aim of this study was to evaluate the diagnostic performances of DWI at high b-value (b = 2000 s/mm2) compared to standard b-value (b = 1000 s/mm2) and A D C r a t i o values ( A D C r a t i o = A D C 2000 / A D C 1000 × 100 ) to differentiate recurrent tumors from posttreatment changes after treatment of HSNCC.
20 patients (16 M, 4 F) underwent MR Imaging between 2 and 16 months (mean 7) after treatment.
Besides morphological sequences, we performed single-shot echo-planar DWI at b = 1000 s/mm2 and b = 2000 s/mm2, and corresponding ADC maps were generated (ADC1000 and ADC2000, resp.).
By considering contrast-enhanced T1-weighted images as references, ROIs were drawn in order to evaluate mean ADC1000, ADC2000, and A D C r a t i o .
The mean ADC1000 and ADC2000 in recurrent tumors were significantly lower than those in posttreatment changes ( P = 0.001 and P = 0.016 , resp.).
Moreover, the mean A D C r a t i o between the two groups showed a statistically significant difference ( P = 0.002 ).
Sensitivity, specificity, and accuracy of A D C r a t i o were 82.0%, 100%, and 90%, respectively, by considering an optimal cutoff value of 65.5%.
A D C r a t i o is a promising value to differentiate between recurrent tumors and posttreatment changes in HNSCC and may be more useful than ADC1000 and ADC2000.
