In 18 patients the perfusion of a malignant head and neck tumour was e
stimated using contrast enhanced dynamic computed tomography. The mean
estimated perfusion was 75.5 ml/100 g/min, varying between 27.9 and 1
31.9. Eleven patients were heated with radiation therapy; the obtained
perfusion rates were significantly different between tumours with a f
avourable and those with an unfavourable early outcome. (C) 1997 Elsev
