Abstract:

Objective: To study the characteristics of Smart 3D SMI blood flow distribution in breast mass and evaluate the three-dimensional image characteristics of blood flow distribution pattern in breast cancer. Methods: Smart 3D SMI features of 145 pathologically confirmed breast cancer were analyzed. The characteristics of blood flow distribution pattern of breast cancer was evaluated in coordination with the characteristics of contrast enhanced ultrasound (CEUS) pattern of corresponding area. Results: Of the Smart 3D SMI of 145 breast cancer patients, the spherical blood flow distribution pattern with abundant blood flow was the most frequent (58 cases, 40%), then was the branched pattern (32 cases, 22%), and dot-line pattern was the least (11 cases, 8%).Comparing the blood flow distribution pattern of CEUS and Smart 3D SMI, CEUS showed that all cases had contrast agent perfusion. Of the patients with dot-line pattern of Smart 3D SMI, 55% showed rough and rich blood flow, while in branched pattern, spherical pattern, expansion pattern and mixed pattern, 75%, 72%, 75% and 52% showed rough and rich blood flow, respectively. Of the various Smart 3D SMI pattern, CEUS showed that in 82%, 75%, 67%, 60% and 58% of dot-line pattern, branched pattern, spherical pattern, expansion pattern and mixed pattern, respectively, the branched blood flow could not been clearly delineated. The perfusion intensity of branched and spherical pattern was higher than that of dot-line pattern, and the difference was significant(P=0.018, 0.006). The perfusion area was mostly located in interior of the mass in dot-line pattern, branched pattern and spherical pattern, and only a few cases had radial perfusion at periphery of the mass. Conclusions: Smart 3D SMI technology is commonly used in the evaluation of ultrasound micro-blood flow distribution of breast mass, spherical pattern and branched pattern are the frequently seen pattern. The three-dimensional morphological characteristics can afford more information regarding the blood flow distribution pattern of breast cancer.
