Echocardiography when it is needed?
Ultrasound is a sound wave with a frequency of over 20 000 MHz, inaudible but capable of penetrating a number of environments, the human body is a type of environment where ultrasound can spread, whereby ultrasound Although it is not harmful, it is very useful for probing internal organs to facilitate a diagnosis of the disease. Diagnostic ultrasound has spread over 50 years of establishment and development, including many types of ultrasound: One-dimensional ultrasound, or one-sided ultrasound, is the first type of ultrasound to allow structure Organs in the form of waves. This type of ultrasound is useful for measuring the size of the heart chambers, blood vessels, heart rate and fetal heart rate. Two-dimensional ultrasound is the most widely used type of ultrasound, it allows you to see the actual image of the body's organs in the most honest way, most abdominal and obstetric ultrasound tests , gynecology only requires a two-dimensional ultrasound to allow full investigation of the issues necessary for the diagnosis.
What is color ultrasound? People often prefer color ultrasound, which is expensive, and the ability to detect the disease is not always appropriate. Color ultrasound, essentially an ultrasound that uses the Doppler effect, is encoded in two primary colors, blue and red, to probe the flow of the body such as blood vessels. So color ultrasound is only needed when probing the heart and blood vessels, most pancreatic liver and pancreas tests and obstetrics do not necessarily have color ultrasound.
WHAT IS 3-WAY ULTRA SOUND?
Three-dimensional ultrasound is essentially a two-dimensional ultrasound, meaning that it is possible to see the internal structure of the organs on each cross section, then to remind the motor of a rotating ultrasound probe and with the help of a computer. The image is made of 3 dimensions. This type of ultrasound is only suitable for obstetrics so far.
IS IT BETTER TO HAVE A THREE-DIMENSIONAL ULTRASOUND THAN A TWO-DIMENSIONAL ULTRASOUND?
As mentioned above, the nature of three-dimensional ultrasound is 2-dimensional ultrasound, so the ability to diagnose disease is not much more than 2-dimensional ultrasound. However, in some cases of deformity of the baby's facial jaw, 3-dimensional ultrasound helps physicians evaluate more accurately ...
HOW IS ULTRASOUND OF THE HEART (ECHOCARDIOGRAPHY) DIFFERENT FROM ULTRASOUND?
The heart is an organ that is constantly beating during operation, so in order to investigate it, the ultrasound machine must have a strong (modern) configuration, high resolution, fast information processing speed. Therefore, the echocardiography machine is often a special-purpose device, which is expensive to buy.
WHAT KNOWLEDGE MAKERS DO NEEDS?
In all types of ultrasound, echocardiography is a complex type of exploration because many of the criteria for exploration are exact. Therefore, cardiologists need training with cardiac clinical courses; General ultrasound; Cardiac anatomy and applied physiology; ECG knowledge; Heart X-ray ... If a young doctor wishes to become a cardiologist in the future, we recommend you to start now. According to our experience, if you have intellectual qualities, after graduating from a regular dermatologist, it only takes 18 months of hard study and you have the key to the heart of everybody.
WHAT INFORMATION DOES ECHOCARDIOGRAPHY GIVES US?
The result of the echocardiogram tells us: 1. The contraction and contraction function of the heart, normally, each cardiac squeeze will be peripheral 60 cc color, so the echocardiogram indicates the ability to eject blood to the periphery. is it normal If it does not reach 60 cc, it means that the body's cells will be deprived of oxygen and will have difficulty breathing, lack of breath. 2. Please indicate whether the heart valve is damaged or not. For cases requiring intervention, or cardiac surgery, the echocardiogram allows the surgeon to know quite well about the parameters they need ... 3. Echocardiography shows the width of the valve hole. how much is the heart, valve closed or open, how much is open ... so that the prognosis and the management of the degree.
