Ultrasound imaging, as the image analysis and diagnosis tool with the largest number of equipment, the largest number of people inspected, the highest safety factor, the fastest inspection results, and the most cost-effective image analysis and diagnosis tool among the four major imaging (CT, MRI, X-ray machines, and ultrasound) equipment in China, has been used in recent years. accounted for the largest proportion of the market in the year.
Ultrasound, CT, and MRI imaging diagnostic methods have their own advantages in disease diagnosis, treatment plan selection, prognosis estimation and regular follow-up treatment. Which imaging diagnostic method should I choose to better apply to my own field?
1. Ultrasound
Ultrasound, an indispensable basic diagnostic medical device, has been popularized in major clinics, nursing institutions, and hospitals. The world’s factory—China, does not sacrifice quality as a premise, produces and exports various types of ultrasound equipment for wholesalers, and doctors import ultrasound at the best price. So how should you choose the corresponding ultrasound for the ultrasound brands headed by Mindray and Sonoscape which are Chinese ultrasound imaging manufacturers?
A.What is ultrasound: Sound waves with a frequency higher than 20,000 Hz are inaudible to the human ear. Utilizing the physical characteristics of ultrasound, various cross-sectional images of organs and surrounding organs can be clearly displayed, which is close to the real anatomical structure.
B-scan ultrasound (B-scan ultrasound) B-scan ultrasound was invented in 1950 by Professor Ian Donald of the University of Glasgow in Scotland.
B.What advantage：
1） Inexpensive, simple, rapid, non-invasive, non-radiative, accurate, continuous dynamic and repeatable scanning, so it is easy to popularize and apply, and is often used as the first choice for solid organs and fluid-containing organs.
2） The imaging speed is fast, and the moving organs can be observed in a timely manner, which is very suitable for the display and measurement of the heart, great blood vessels and gallbladder; no radiation.
C.What shortcoming:
1） Ultrasound is hindered by gas and bones, so it is not suitable for the examination of gas-containing organs such as the lungs, digestive tract and bones. However, with the development of body cavity probes and the application of acoustic contrast agents for the digestive tract, gastric ultrasound has been applied clinical.
2）On the other hand, the accuracy of ultrasonic diagnosis is affected by the operator’s experience, examination skills and seriousness.
2.CT
CT (Computed Tomography), that is, electronic computerized tomography, can be divided into X-ray CT (X-CT), ultrasonic CT (UCT) and γ-ray CT (γ-CT) according to the different rays used.
A. advantage:
1)The prominent advantages of CT are high density resolution, clear cross-sectional anatomical relationship, and good display of lesion details. In particular, plain films cannot show fine calcification, liquefaction, necrosis and other structures, which is very helpful for qualitative diagnosis.
2)Relatively cheap, safe and fast, suitable for the first choice of inspection.
3)The inspection speed is fast, especially suitable for emergency inspections, such as trauma and cerebrovascular accidents.
4)The CT value of photosensitive areas of different tissues can be obtained for quantitative analysis.
5)Enhanced scanning is helpful for better display and qualitative diagnosis of lesions.
6)Image reconstruction is possible.
B. shortcoming:
1)There are too many bone artifacts in some parts, which affect the display of surrounding soft tissue structures, such as the base of the skull and the spinal canal.
2)Affected by respiratory movement, it is easy to miss small symptoms, such as lung and liver.
3)The amount of X-ray radiation is large.
4)The reconstructed image has many artifacts.
5)High-speed CT has greatly improved the inherent defects of CT machines,
A.advantage :
1)X-rays have a strong penetrating ability, and the inspection is like taking a picture of a flat image of the inside of the body. Due to the uneven density of the irradiated object, the negative film after inspection will form black and white in different colors. It can usually be seen that the color of the bones on the film is off-white, and the soft tissue is not clearly visualized.
2)It is mainly used for the preliminary examination of some diseases, and it is easy to find the tissues and structures with obvious lesions. It is the first choice for the initial screening of diseases, and the price is cheap.
B.shortcoming:
X-ray examination can only provide a two-dimensional plane image, and the imaging is easily affected by clothing, packing and even thick soft tissue, so it is generally used as a preliminary examination.
Notice:
X-rays have slight radiation. To be on the safe side, pregnant women and those who are planning to become pregnant are not recommended to take X-rays, so as not to affect the normal development of the fetus.
Therefore, to choose a medical imaging device that is most suitable for you, it is recommended that you consider multiple factors such as the price, performance, function, and usage scenarios of the device. You can consult a professional medical equipment company or salesperson for more detailed information and advice.
