Analysis of CT Perfusion Blood Flow Maps in Patients with Lung Cancer: Correlation with the Overall Survival

Abstract

Computed Tomography perfusion (CTp) is a func- tional imaging technique with a wide application in the oncologi- cal field. CTp allows detecting the presence of tumour abnormal hemodynamic patterns, by analysing the tissue temporal varia- tions occurring after the administration of the contrast medium. This work presents a novel approach to extract meaningful features from blood flow (BF) maps of lung cancers, which could act as a prognostic image-based biomarker.
