Over the years, there are many medical imaging techniques that have come into use. CT scan, x-ray, digital X-ray, ultrasound, and MRI are some of these techniques. The techniques have their individual pros and cons which allows them to be applied differently depending on the situation. For example, when imaging bones and other hard tissues, it is most appropriate to use x-ray. When one needs 3d ultrasound Dallas offers the perfect location to visit.
On the other hand, MRI is suitable for imaging soft tissues because it gives a high level of accuracy. Ultrasound on the other hand is a very safe imaging method that is often used to image infants in the womb. This method of imaging makes use of high-frequency sound waves to create images of body organs. The waves are sent into the body using a handheld transducer.
The waves then bounce off body organs and register an image on the screen. The term ultrasound is usually to imply the fact that the sound used is usually at a frequency that the human ear cannot detect. The range of the frequency used is usually between 2 to 18 megahertz. Higher frequencies usually produce images of better quality.
However, higher frequencies present one major shortcoming where they are more readily absorbed by the skin and other tissues. This usually prevents the sound from penetrating deeper into the body. On the other hand, lower frequency sounds are able to penetrate deeper into the body to produce images of organs seated deep into the body. However, the one shortcoming that is associated with them is that they form images of inferior quality.
The term sonography is at times used to refer to ultrasound. The process produces images which are known as sonograms. Medical professionals such as cardiologists, radiologists, and sonographers can perform sonography. However, sonographers normally carry out the process in health facilities where tasks are divided and there is specialization of tasks. Sonographers are usually trained specifically to handle machines used in ultrasound.
Once the sonographer produces the images, they are transmitted to a cardiologist or radiologist to be interpreted. In some cases the practitioner that does the interpretation of the images may be located at an offsite facility. In this case, remote radiology is normally employed. Remote radiology makes use of high quality technologies that use high speed internet connection. The sonograms get encrypted for privacy and sent over to the interpreter.
Radiation is not used in ultrasound scans because the process uses sound waves. This makes it very safe. The safety of the technique allows it to be used in examining fetal development. Problems in internal body organs such as heart, kidneys, liver and abdomen can also be detected using sonography. These organs are usually very delicate and can be damaged severely if techniques that are based on ionizing radiation are used to image them.
When used for evaluation of fetal development, this method is used at different stages. It can also be used to determine the gender of the baby before birth. No risks have been associated with the use of this method to image fetuses in the womb.
