SOUND WAVES THROUGH Initially, continued Riris, people unaware of the adverse effects of X-ray radiation up to continuous use for years. Later became known only to birth defects, among others, thanks to X-ray radiation or other wave in radiology. "Since then, radiological examinations of pregnant women began to be avoided. Especially during pregnancy under 12 weeks. Therefore, when the formation of the organs of the fetus is not perfect." When the initial cell division is disturbed by radiation, it is feared will bring up the defects in the body such as hands, feet and head. Or abnormalities in the heart, lungs, kidneys, or cancer. Defects or abnormalities are usually discovered when the baby is born or when it is many years old. Through 12 weeks of gestation, the formation of the organs of the fetus is perfect, so some experts believe the fetus will not be affected whatsoever. But according Riris, if not very forced, doctors generally recommend that pregnant women still do not undergo X-ray images using "Even if compelled, must wait for safe time. Such examination was delayed until the last trimester or just after 6 months of pregnancy. It is also still done by giving priority to safety. For example, protecting the body with a blanket layer of lead for radiation effects can be minimized. Another case with ultrasound. Although also the development of radiology, the impact is in no way harm the fetus. Work ultrasound, clear Riris, using sound waves. This is confirmed dr. Rudianti, SpOG, on separate occasions. Ultrasound, obstetricians clearly who is familiarly called Anti this is one diagnostic method to detect fetal development. "Instead of ultrasound with all the advantages, to overcome the limitations of roentgen diagnosis that is rich in radiation exposure." According to Anti, an ultrasound examination uses high frequency sound waves will not cause adverse effects, both for pregnant women, fetuses, and physicians who perform ultrasound. "Unfortunately, there are still a handful of doctors who do not understand well how the ultrasound. It may be because the result is an image, they think Ultrasound uses X-rays and contain radiation, so its use should be avoided." Although ultrasound is done each month, said Anti, until recently did not show significant difference in body weight and birth length. Also no effect on child development, learning ability, or create visual impairment, hearing, and nerves. What is clear, he added, pregnant women are entitled to an explanation of the purpose / objective ultrasound examination. Including the advantages and possible disadvantages. Only When Forced In general, pregnant or not, is not radiological examination will have a negative impact on the body. With notes, Riris demolished, "Inspection not done repeatedly, such as 5-10 times a year. Because, among others, could potentially cause infertility, cancer, skin disorders or other." The impact did not snap. Time consuming and can not be certain when emergence. Therefore, the message Riris, perform radiological examination only if recommended by a doctor for medical indications. Meanwhile, according to Anti, ideally before pregnancy, a woman must consult with the doctor concerned to seek the possibility of the disease. Like the lungs, abdominal cavity, abnormalities in the brain, or bone fractures that eventually expected to require radiological investigation. When the safe or the disease can be treated, pregnancy can be immediately scheduled. Unfortunately, radiological examination is often performed due to sudden demand. For example, the mother had an accident and need immediate radiological examination. Usually the doctor will look at the condition of the patient. When you can wait until the end of pregnancy, the examination will be deferred radiology. But if very urgent / emergency, such as detecting blockage of blood vessels in the brain, CT-scan is usually the choice is permitted. "This may be due to save the life of the mother." Meanwhile, to minimize its effect on the fetus, the mother's body will be protected by a blanket layer of lead.
