Several imaging techniques have been invented over the years to be used to image the body. Some good examples include x-ray, CT scan, digital x-ray, MRI, and ultrasound. Each of these methods offers various advantages and disadvantages that make them suitable for use in different situations. For instance, x-ray is excellent for imaging bones and other hard tissues in the body. When in need of 3d ultrasound Dallas should be visited.
When imaging soft tissues, MRI should be used due to the high accuracy level that it provides. On the other hand, imaging of fetuses in the womb is done using ultrasound because it is very safe. In ultrasound, images of body organs are generated using sound waves of high frequency. A handheld transducer is used to send the waves into the body.
The sound waves then bounce back from body organs and generate a picture on a screen. The word ultrasound is normally used to refer to the high frequency of the sound used in this process. The frequency normally ranges between 2 and 18 megahertz. The higher the frequency, the better the quality of images produced.
Higher sound frequencies however are problematic because they tend to be readily absorbed by tissues like the skin too. This normally stops the sound from reaching greater depths into the body. Lower frequency sounds, nevertheless, have the ability to go deeper into the body to form images of organs situated deeper into the body. The one demerit, however, that is related with the lower frequency sounds is that they create low-quality images.
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.
After the images are produced by the sonographer, they are sent over to the radiologist or cardiologist for interpretation. There are cases where the practitioner who is supposed to interpret the images may be located offsite. In such a case, remote radiology is usually employed. Remote radiology involves the use of high-quality technologies that work on fast-speed internet connection. The images are encrypted for privacy reasons and transmitted to the interpreter for interpretation.
The use of sound waves means that ultrasound scans do not use radiation, which makes them very safe. In fact, they are so safe that they are routinely used to evaluate fetal development. They are also used to detect problems in vital internal organs such as kidneys, abdomen, heart, and liver. The use of radiation-based technique to image these organs can cause more harm than good.
If sonography is used for assessment of fetal development, it is carried out in various stages. Sonography may also be used in establishing the gender of a fetus before it is born. There are no dangers that have been found to be related with the use of this technique to image infants in the womb so far.
