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.
These waves usually generate an image on the screen when they bounce off body organs. The sound generated is referred to as ultrasound because it cannot be detected by the human ear due to its high frequency. The frequency usually ranges between 2 and 18 megahertz. Images generated by higher frequencies are usually of higher 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.
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.
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.
