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 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.
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.
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.
After the sonographer has produced the images, the next step is to forward them to a radiologist or a cardiologist for interpretation. At times, the interpreting practitioner might not be located in the same facility as the sonographer. Remote radiology is usually utilized in such a case. In remote radiology, high quality technologies that operate on fast internet connection are used. Encryption of the images is done to secure them while being sent for interpretation.
Using of sound waves implies that sonography scans do not involve the use of radiation, which renders it quite secure. As a matter of fact, the waves are so safe in that they are habitually used to assess fetal development. The sonograms are also used to establish problems in vital organs like the heart, kidneys, abdomen and liver. Use of a technique that uses radiation can lead more of danger than good when used to image these organs.
There are various stages of examining fetal development using this method. The gender of the baby can also be discovered before the baby is born through sonography. So far, there are no risks that have been determined to be associated with imaging fetus using ultrasound imaging.
