Ultrasound Scan


What is an ultrasound?

    Ultrasound imaging is a medical procedure that employs high-frequency sound waves to capture real-time images of the inside of the body. It is also referred to as sonography.

    Similar technologies, such as sonar and radar, help the military detect aircraft and ships. Using an ultrasound, a physician can see problems with organs, vessels, and tissues without making an incision.

    Ultrasound, unlike other imaging techniques, does not utilize radiation. As a result, it is the procedure of choice for observing a developing foetus during pregnancy.

How to prepare for an ultrasound

    Preparation for an ultrasound will vary based on the location or organ being examined.

    Your physician may instruct you to fast for eight to twelve hours before your ultrasound, particularly if your abdomen is being examined. Food that has yet to be metabolized can obstruct the sound waves, making it difficult for the technician to obtain a clear image.

    For an examination of the gallbladder, liver, pancreas, or spleen, you may be told to consume a fat-free meal the evening before your test and then to fast until the procedure. However, you may continue to drink water and take your prescribed medications. For other examinations, you may be asked to consume a large amount of water and hold your urine so that your bladder can be better visualized when filled.

    Before the exam, you should inform your doctor of any prescription medicines, over-the-counter medications, or herbal supplements you are taking.

    Before the procedure, it is essential to observe your doctor's instructions and ask any questions you may have.

    Ultrasound poses minimal dangers. Contrary to X-rays and CT exams, ultrasounds do not utilize radiation. Therefore, ultrasounds are the preferable method for examining a foetus during pregnancy.

How an ultrasound is performed

    Before the examination, you will wear a hospital robe. You will likely lie on a table with a portion of your body exposed for the test.

    A sonographer, an ultrasound technician, will administer a special lubricating jelly to your skin. This inhibits friction so the ultrasound transducer can be rubbed on the patient's skin. The transducer resembles a microphone in appearance. The jelly also aids in the transmission of sound pulses.

    The transducer transmits sound vibrations with a high frequency through your body. They resound when waves strike a dense object, such as an organ or bone. These echoes are subsequently reflected into a computer. The frequency of the sound waves is too high for the human ear to detect. They create an image that the physician can


    Depending on the area being examined, you may be required to adjust your position to allow the technician easier access.

    Following the procedure, the gel will be removed from the epidermis. The procedure typically takes less than thirty minutes depending on the examined area. After the process has concluded, you can resume your normal activities.

After an ultrasound

    After the examination, your doctor will examine the images for any abnormalities. They will contact you to discuss the results or to schedule a subsequent appointment.

    Depending on the studied area, you may be required to undergo additional diagnostic procedures such as a CT scan, an MRI, or a tissue biopsy if the ultrasound reveals anything aberrant. If your doctor can diagnose your condition based on the ultrasound, they may promptly begin treatment.
