For diseases of the abdominal and pelvic system, especially those of the blood duct system, the main examination methods of the transmission system are color Doppler ultrasound, enhanced CT angiography and digital subtraction angiography (DSA). Among them, DSA is the gold standard of
angiography, but it is an invasive examination, which is complicated, time-consuming and laborious, and the skill of intubation is very high. Enhanced 3D-CT blood tube imaging has been gradually used in clinic because of its advantages such as fast imaging speed and wide imaging range. It
has good vascular imaging conditions and satisfactory vascular imaging results in all parts of the human body, but this examination is radioactive and is not beneficial to young women of childbearing age, children and frail patients. The purpose of this paper is to further illustrate the value
of magnetic resonance angiography (CTA) in displaying pelvic vessels by comparing the three-dimensional model of magnetic resonance angiography (CTA) and magnetic resonance angiography (MRA) in healthy young women. The results showed that for the venous system, CTA usually showed only the
internal and external iliac vein, but not for the uterine vein and other branches of the internal and external iliac vein, and almost no imaging for the anterior sacral vein. CE-MRA can not only display 1-4 grade arteries to the same extent, but also show more branches of superior and inferior
gluteal arteries, and show more abundant veins, especially presacral veins. For cases such as gynecological pelvic floor surgery, it is necessary to know the vascular network of presacral region before operation. In a word, for clinical diagnosis and treatment value, the 3D-CT imaging is the
first choice.
