Black and White Ultrasound and Doppler Color Ultrasound
Clinical Application: Suitable for heart, liver, bile, spleen, pancreas, obstetrics and gynecology, peripheral blood, superficial organs (such as eyeball, thyroid, breast, scrotum, etc.) soft tissue examination of various diseases .
Generally speaking, due to its own limitations, black and white B-ultrasound is usually equipped with only one probe, which can only be used to examine the abdominal cavity, such as liver, gallbladder, pancreas, spleen, kidney, ureter, bladder, prostate, uterus and accessories, general obstetric examination, pleural and abdominal fluid exploration, etc. And color B is exceeded to configure 3 probe commonly, besides can check abdominal cavity, still can check heart, skin superficial surface, lymph node, mammary gland, thyroid gland, submandibular gland, parotid gland, peripheral blood tube, eyeball, testis, appendix. Color ultrasound can understand the blood supply of these organs, especially for the blood flow in some lumps, which can roughly distinguish between benign and malignant.
Color super and black and white super is not only the difference in color:
Compared with a single black and white B-mode ultrasound, color B-mode ultrasound has more functions, more ways to diagnose diseases, more clear diagnosis of diseases, and its image resolution is better than black and white B-mode ultrasound. A few superficial organization organs, wait like thyroid gland, mammary gland, parotid gland, testis the examination needs to do color to exceed, in addition, a few abdominal examination, wait like tumor, obstructive icteric, liver cirrhosis, vascular sex pathological change, should use color B to exceed commonly. In addition, if the umbilical cord blood flow status is needed for obstetric examination and the middle and late pregnancy needs to be determined whether the umbilical cord around the neck, color B ultrasound should be selected. Of course, color ULTRASOUND is more expensive than black and white Ultrasound.
Compared with black and white ultra, color ultra has more advantages besides the function of color display:
First, high resolution and strong sensitivity, can find black and white super can not show the small lesions;
Two, more functions, according to the need to exchange at any time the application of B method, M method, Doppler method (tissue, energy, blood flow display), conducive to the detection of lesions and tumor benign and malignant judgment;
Three, more widely used, with a variety of frequency probe, can carry out the body of each organ, all kinds of disease inspection;
Fourth, the technology is more advanced and can support the application of a variety of new technologies, such as real-time contrast-enhanced ultrasound and ultrasound-guided puncture biopsy and treatment.
