Abstract：Angiogenesis is an important feature of malignant neoplasm and is the fundamental of genesis and growth of tumors. CT perfusion imaging (CTPI), as one of the functional imaging techniques, can detect neovascularity of neoplasm. It has been applied in a range of clinical areas, such as lesion characterization, staging, predicting patient outcome or response to therapy, assessment of response to different therapies, and so on. However, the major limitations of CTPI are the risk of exposure to ionizing radiation and the dispute of reproducibility of parameters which limit its routine use. Low-dose CT perfusion can be better used in clinical work. In this article we reviewed the basic principles, technique, and various oncological applications of Low-dose CT perfusion.
