CT灌注成像作为功能成像技术之一,将组织学功能与解剖学结构完美地结合在一起,在血管性病变及肿瘤性病变中有着很高的临床应用价值,在乳腺肿瘤中的应用尚处于起步阶段。此技术可用于乳腺肿瘤的临床诊断、鉴别诊断及治疗监测等几个方面,因而有着广阔的应用前景。本文就CT灌注成像技术的基本原理及其在乳腺肿瘤中的临床应用予以综述。 As one of the functional imaging techniques, CT perfusion imaging perfectly integrates the histological functions and anatomic structures and has high clinical value in vascular lesions and neoplastic lesions. The application of CT perfusion imaging in breast tumors is still in its infancy stage. This technology can be used in clinical diagnosis of breast cancer, differential diagnosis and treatment monitoring, and several other aspects, which has a broad application prospects. This article summarizes the basic principle of CT perfusion imaging and its clinical application in breast neoplasms.
