Many people today have most probably heard about sonography or ultrasound. Basically, it is the commonest diagnostic method used today for obstetrics purposes as well as other important parts of medicine. For obstetric purposes, sonography is used to scan the uterus to confirm a pregnancy, to determine the sex and age of the baby, tell the exact position (i.e. how the fetus is lying inside the womb), and basically tell the general condition of the fetus. As mentioned, there are several other uses of sonography such as scanning the internal organs of the human body in an effort to diagnose underlying medical conditions such as blood vessels, brain, heart etc.
The equipment used during this sonography procedure is simply a handheld transmitter known as a transducer which helps in emitting high frequency sound waves. This transducer equipment is passed over the skin on some special gel to create echoes or the sound waves, which in turn create an image of the internal organs of the patient. Sonography is safer than X-RAY as it used sound waves in place of radiation thereby not putting the health of the patient at risk. As mentioned, the images are used to prevent, diagnose, and treat underlying medical conditions.
The field of sonography has several specializations – for instance, vascular technologist is a sonography field that specializes in imaging and helping in testing of human blood vessels. On the other hand, ultrasound technicians who specialize in the abdomen examine the condition of various abdominal organs like the spleen, liver, pancreas, urinary tract and also soft tissue blood vessels found in the abdomen.
The other common type of specialization in Sonography is the heart, which is known ad echocardiography. Their main job entails evaluating the flow of blood to the heart and checking the state of the blood vessels and blood valves around and within the heart. Neurosonology sonographers are qualified to scan and diagnose problems that involve the spinal cord, brain, and the nervous system as the name would imply. Equally, the Ophthalmology sonographer examines conditions of the eye.
Nearly all sonography jobs have the same job description and duties. For one, they have to look into, and manage the history of a patient, clearly analyze information in different diagnostic procedures, determine the needs of a patient by scanning their internal condition, and finally writing an oral or written summary of the findings for the physician. People searching for employment in sonography can thus collaborate with physicians, doctors, and nurses.
Today, most people prefer sonography to X-Ray due to their safe non-invasive nature. This has created a high demand for sonography technicians. Sonography is cheaper and safer as compared to X-RAY as it uses sound waves instead of harmful radiations. As time goes on and new technology advances, the demand for sonography jobs will without a doubt increase. Technology advancements today ensure there are 3D and 4D images being generated. It is in light to this that all sonographers should keep abreast with the latest happenings in the field and the latest news, thereby creating more sonography job opportunities.
