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 ideal for scanning soft tissues since it is more accurate. Ultrasound is a very safe imaging technique that is frequently used to form images of fetuses in the womb. This technique uses sound waves of high frequency to form images of organs. The sound waves are transmitted into the body by use of a handheld transducer.
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.
There is however one major problem caused by frequencies of higher magnitude whereby the skin and other tissues usually absorbs them more readily. When this happens, the sound is prevented from penetrating to deeper organs of the body. On the contrary, images of deeper-seated organs are generated when sounds of lower frequencies are used. This is because the sound has the ability to penetrate deeper into the body. However, the images generated by such sounds are usually of low quality as well.
Another name used to refer to ultrasound scan is sonography while the images that are produced through this process are called sonograms. The process can be done by various medical practitioners, including radiologists, sonographers, and cardiologists. However, in a hospital setting where tasks are divided and practitioners are specialized in their work, the scans are done by sonographers. Sonographers are specifically trained in the use of ultrasound machines.
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.
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.
