Zusammenfassung:	Description of a new noninvasive method for the evaluation of tissue oxygenation in head and neck cancer. Prospective nonrandomized controlled study in an academic medical center on 20 patients with neck metastases of head and neck cancer. Metastases were investigated using color duplex sonography and pO 2 histography. The vascularization in sonography was quantitatively evaluated by color pixel density and compared to the pO 2 values of the same nodes. The correlation between vascularization and flow velocity was 0.71. For the mean/median pO 2-values and for the pO 2 readings
