From: Head and neck malignant lymphoma and squamous cell carcinoma discernment, is DWI conclusive?
A male patient, 73 years old, suffering from change in quality of voice and dysphagia (proved pathologically as laryngeal SCC). A, B Axial T1- and T2-weighted image showing an abnormal signal intensity mass lesion (18 × 11 mm in size) involving the right glottis and supraglottic regions. The lesion displays iso- to hypo-signal in T1WI and hyperintense signal in T2WI. C, D DW-MRI at b = 1000 s/mm2, the ADC map (mean ADC = 1.3 × 10–3 mm2/s). E, F DW-MRI at b = 1500 s/mm2, the ADC map (mean ADC = 1.2 × 10–3 mm2/s). G, H DW-MRI at b = 2000 s/mm2, the ADC map (mean ADC = 1.1 × 10–3 mm2/s). The lesion is seen truly restricted on DWIs with low ADC values on the corresponding ADC maps with the lowest ADC value at b = 2000 s/mm2
