Abstract

SUMMARY


Introduction: Lung tumour perfusion CT may help to evaluate characteristics and haemodynamics of lung cancer. This research was carried out to assess changes in haemodynamics and contrast enhancement pattern of lung cancer lesions.
Methods: 12 patients were enrolled to the study underwent perfusion CT of lung tumour. Perfusion paramerters were obtained from perfusion CT maps.
Results: perfusion paramerters increased in malignant tumour with measured blood flow of 33.15 ±15.7 ml/100g/min, blood volume of 17ml/100g and tumour volume ranged from 7
– 577ml. blood volume in small tumours was higher than that in larger lesions. The higher homogeneity in blood flow was found in small tumours.
Conclusion: Lung tumour perfusion CT could be used to assess changes in tumour haemodynamics that may help in pretreatment of unresectable lung cancers.
