What does b super echo mean in the examination?

When shooting B-ultrasound, did you know about B-super echo? What's the difference between low echo and low echo? The following is the meaning of B-mode ultrasonic hyperecho that I sorted out for you for your reference!

What does it mean that B-ultrasound shows low echo, high echo and no echo respectively?

Ultrasound uses echoes to determine the properties of matter. Echo can be divided into high echo, slightly high echo, low echo and no echo. High echo is also called strong echo. If it is in the liver, it is more common in intrahepatic bile duct stones and calcification, and low echo is more common in tumors, such as cavernous hemangioma and liver cancer.

What do B-ultrasound high echo and low echo mean?

Echo is an ultrasonic term. It can be divided into strong echo, equal echo, low echo and no echo. Generally speaking, compared with surrounding tissues, it is related to tissue density.

Strong echo refers to dense lesions, such as stones and calcification.

Hypoechoic refers to edema or low density in the lesion area, which can be seen in breast hyperplasia, breast tumor or hysteromyoma.

Anechoic polydactyly cyst, etc.

Ultrasonic echo

Ultrasonic wave is a kind of sound wave that can be heard by normal human ears, and its frequency is above 20000 Hz. Ultrasonic examination is an examination method that uses the difference between the physical characteristics of ultrasonic waves and the acoustic characteristics of human organs and tissues to display and record in the form of waveforms, curves or images, so as to diagnose diseases. In the early 1940s, we explored the use of ultrasound to examine the human body. In the 1950 s, we studied and used ultrasound to make organs form ultrasonic images. In the early 1970s, we developed real-time ultrasound technology to observe the activities of the heart and fetus. Ultrasonic diagnostic equipment is not as expensive as CT or MRI equipment, and can obtain images of any cross section of organs and observe the activities of moving organs. It is a non-invasive examination with fast imaging, timely diagnosis, no pain and danger. Therefore, it has been widely used in clinic and is an important part of medical imaging. The disadvantage is that the contrast resolution and spatial resolution of the image are not as high as CT and MRI. This paper only introduces gray-scale ultrasound.

B-ultrasound scans the human body with ultrasonic sound beam, and obtains images of internal organs by receiving and processing the reflected signals. There are many kinds of ultrasonic instruments in common use: Type A (amplitude modulation type) uses amplitude to indicate the strength of reflected signal, which one is displayed? Echo map? . M-shape (spot scanning type) represents the spatial position from shallow to deep in the vertical direction, and represents time in the horizontal direction, showing the motion curve of the spot at different times. Both of them are one-dimensional displays, and their applications are limited. B-type (brightness modulation type) is ultrasonic tomography, referred to as? Ultrasonic imaging? . The intensity of the received signal is represented by light spots with different brightness. When the probe moves along the horizontal position, the light spots on the display screen also move synchronously along the horizontal direction, and the tracks of the light spots are connected into a cross-sectional view of ultrasonic sound beam scanning, which is two-dimensional imaging. B-ultrasound is widely used in clinic because of its clarity, intuition and strong sense of hierarchy. As for the D-type, it is made according to the principle of ultrasonic Doppler, and the C-type displays the sound image perpendicular to the cross section of the sound beam in a scanning way similar to that of a television. In recent years, ultrasonic imaging technology has been developing continuously, such as gray scale display and color display, real-time imaging, ultrasonic holography, penetrating ultrasound, ultrasonic computed tomography, three-dimensional imaging, intracavity ultrasound and so on.

B-ultrasound is often used to judge the position, size and shape of organs, determine the scope and physical properties of lesions, provide some anatomical maps of gland tissues, and distinguish normal and abnormal fetuses. Widely used in ophthalmology, obstetrics and gynecology, cardiovascular system, digestive system and urinary system. At present, ultrasonic imaging technology has also been applied in the field of traditional Chinese medicine, such as using Doppler flowmeter to detect the blood flow of various pulse conditions. So as to provide an index for objectification and quantification of pulse condition; B-ultrasound can also be used to study the objectification of TCM syndromes.
