What are the advantages of contrast-enhanced ultrasound puncture needle tumor biopsy

The advantages of biopsy under CEUS are as follows: Puncture biopsy of tumor under CEUS is a new technology emerging at present, which can improve the display ability of small blood vessels and low blood flow in the tumor, and also show the different characteristics of benign and malignant tumors and perfusion patterns. Ceus can well display the distribution of microcirculation in the tumor and reflect the richness of new blood vessels in the tumor. This is CEUS evaluation. Basis of intratumor blood perfusion. Ceus technology can make the color blood flow signal seen in conventional ultrasound more prominent, and also has unique advantages in the display of microvessels and low-speed blood flow in the tumor. By selecting the contrast enhancement area as the target for puncture biopsy, puncture can accurately reach the active area of the tumor, improving the accuracy of puncture biopsy, and to a certain extent, improving the satisfaction of puncture and sampling of the lesion. It has important clinical value to reduce the number of puncture, reduce postoperative complications and alleviate patients' pain. This method is especially suitable for the puncture of heterogeneous tumors, such as ovarian tumors, most of which are cystic solid. Ceus can clearly show the active areas of tumors and guide the puncture sampling.
