Centerline analysis of aortic CT angiographic examinations: benefits and limitations.
OBJECTIVE
The purpose of our study was to illustrate workflow, benefits, and limitations of centerline analysis compared with double oblique multiplanar reformations using aortic CT angiography data.


CONCLUSIONS
Semiautomatic centerline analysis is beneficial for the assessment of aortic geometry and allows precise measurements of aortic diameters and lengths. It can be simple, fast, and reproducible, but it should be used with care considering its inherent limitations. Manually adjusted multiplanar reformations remain an essential tool for intuitive visualization of the vascular anatomy.
