The most effective technique for the treatment of most illnesses is early detection. Cancer, for instance, has higher probability of being treated or put under control once detected earlier. Treatments including chemotherapy, surgery, radiation therapy and many others have the capacity to kill most cancer cells when administered to the patient during the early stage.
Evolutions and advancements in the medical field have paved the way for early detection of some of the most terminal diseases that are threats to human life. One of these is diagnostic sonography or in laymans term, ultrasound. Ultrasound uses sound waves to develop images of what is happening inside a persons body. This diagnostic tool is commonly used by physicians to evaluate symptoms such as pain, swelling or infection. Thus, it is a very useful tool in examining various internal organs of the body such as the heart, liver, gallbladder, uterus, kidneys, pancreas, spleen, thyroid glands, and scrotum. However, it is mostly used by obstetricians during pregnancy to give the expectant parents a sneak peak of their little angel inside the womb.
Physicians use a medical instrument called a transducer that is used to do the scanning. A transducer is a hand-held device that resembles a microphone and is attached to the scanner. It emits inaudible, high-frequency sound waves into the body and subsequently records the echoes that it receives. The resulting image that is immediately visible on the monitor was created based on the amplitude, frequency and time it took for the ultrasound signal to return within the area that is being examined, considering the type of body structure and composition of tissues of the patient. A small amount of gel is applied to the skin area to allow the sound waves to best travel from the hand-held device to the area under examination and back.
Way back, ultrasound has been simple. It detects sound waves from within the body to provide information regarding the due dates of pregnancy, unveil the presence of twins or other multiples and detect ectopic pregnancies in the early stage. The imaging was only two-dimensional (2D). However, with the emergence of improvements surrounding this diagnostic tool, three-dimensional (3D) and four-dimensional (4D) images are now available, meaning, expectant parents can now have a preview of what their smiling babies in a womb look like.3D 4D ultrasound week by week are optional. However, it is best for parents who want to observe the growth and development of their little one inside or for doctors to monitor their patients cases.
Other than providing expectant mothers a clearer view of their unborn babies, 3D 4D ultrasound week by week is also used by obstetricians and physicians to help them detect certain birth defects such as cleft lip, which cannot be seen on a standard ultrasound.
In most cases, such as pregnancy, ultrasound is non-invasive. It does not use needles or injections thus making it painless. It can be uncomfortable, but it is not that painful. This procedure is more accessible and cheaper than most diagnostic techniques and does not expose the patient to radiation. It also captures images that x-rays could not quite catch, such as those of the tissues. Moreover, ultrasound poses no known harmful effects to humans. Indeed, ultrasound is one of the best advancement the medical field has ever come up with.
