Abstract:
Angiogenesis is an important feature of malignant neoplasm and plays an essential role in the genesis,growth and metastasis of tumors. CT perfusion imaging (CTPI),as one of the functional imaging techniques reflecting neovascularity of neoplasm,perfectly combines anatomical imaging with physiological information and can be used in a range of clinical areas,such as differentiation between benign and malignant lesions,early detection of malignancy or metastasis,prediction of tumor behavior and the assessment of responses to therapies. Many researches have been done on perfusion CT in tumors of the brain,thyroid gland,salivary gland,mammary gland,lungs,liver,esophagus,kidney,colorectum,and so on. The present article reviews the basic principles of perfusion CT and its clinical application in tumors.
