CT血管成像在腹盆腔肿瘤诊治中的临床应用及进展

Application and progress of CT angiography in diagnosis and treatment of abdominal and pelvic tumors

腹部肿瘤较为常见,来源广泛,部分肿瘤的形态学表现缺乏特征性、位置变化较大,给诊断带来一定的困难。腹盆腔原发性肿瘤的血供一般来自起源器官或起源组织,肿瘤的生长方式及形态的不同,肿瘤血管的影像表现也不尽相同。随着CT技术的发展,腹部CT血管成像(Computed Tomography Angiography,CTA)已成为一种显示腹盆腔肿瘤供血动脉及肿瘤血管的重要检查方法,对于肿瘤的早期定位及定性诊断、肿瘤分期、治疗方式的选择、预后生存率的判断都有着举足轻重的价值。

Abdominal tumors are relatively common,with a wide range of sources,and some of them lack characteristic morphological manifestations and have great changes in location,which brings certain difficulties to diagnosis.The blood supply of primary abdominal and pelvic tumors usually comes from the organs or tissues of origin.With the development of CT technology,Computed Tomography Angiography(CTA)has become an important examination method to display the blood supply arteries and blood vessels of abdominal and pelvic tumors.It is of great value for the early localization and qualitative diagnosis of tumors,tumor staging,choice of treatment methods,and judgment of prognosis and survival rate.
