What does ultrasound check?

Ultrasound is not new to people's lives, but ultrasonic technology has been applied to all aspects of life and has brought many benefits to people. For example, ultrasonic technology has achieved good results in the medical field. The medical use of ultrasound is mainly to provide accurate examination results. Let’s take a look at what ultrasound checks.

Ultrasound is an advanced medical technology with good directionality and is a diagnostic method commonly used by doctors. Ultrasound is divided into A-type (oscillometric) method, B-type (imaging) method, M-type (echocardiography) method, sector-type (two-dimensional echocardiography) method, Doppler ultrasound method, etc. In fact, the Type B method is divided into three categories: line scanning, fan scanning and arc scanning, that is, the fan method should be included in the Type B method.

Type A method

Type A method is more commonly used, and it determines whether there are abnormal lesions based on the amplitude, number of waves, and order of waves on the oscilloscope. It is relatively reliable in diagnosing cerebral hematoma, brain tumor, cyst, chest and abdominal edema, early pregnancy, hydatidiform mole, etc.

Type B method

Type B method is the most commonly used method and can obtain various cross-sectional images of the human internal organs. It is very effective in diagnosing the brain, eyeball (such as retinal detachment) and orbit, thyroid gland, liver (such as detecting small liver cancer with a diameter of less than 1.5 cm), gallbladder and bile duct, pancreas, spleen, obstetrics, gynecology, urology (kidney, bladder, prostate, scrotum), identifying abdominal masses, large vessel diseases in the abdominal cavity (such as abdominal aortic aneurysm, inferior vena cava thrombosis), and large vessel diseases in the neck and limbs. The graphics are intuitive and clear, making it easy to detect smaller lesions.

M-type method

The M-mode method records the echo distance change curve between the heart and other structures in the body and the chest wall (probe). From this curve, the characteristics of the heart wall, ventricular septum, heart chamber, valve, etc. can be clearly identified. Electrocardiogram and phonocardiogram are often displayed and recorded simultaneously to diagnose various heart diseases. This method has a very high compliance rate for certain diseases such as intraatrial myxoma.

Fan Method

The fan-shaped method can obtain various cross-sectional images of the heart and observe the different manifestations of the heart's contraction and diastole. Because it sees more comprehensive graphics, the diagnostic range is much greater than the M-type method, and it is more detailed

And exact. In addition, this method can also be used to diagnose diseases of the liver, gallbladder, pancreas, spleen, brain, obstetrics and gynecology, etc.
