Ultrasound, also known as sonograms, is a non-invasive imaging test that uses sound waves to produce real-time videos and images of structures in the body. It allows the doctor to see the soft tissues inside your body without making any cuts. Unlike X-ray, ultrasound does not use radiation so it’s completely safe. The images can provide valuable information for diagnosing and assisting treatment for a range of diseases and conditions. Commonly associated with pregnancy testing, it also diagnoses a wide range of medical conditions. In this blog, we’ll discuss the ultrasound scan procedure, purpose and potential risks associated with ultrasound imaging.
Ultrasound Scan Procedure: How is the Ultrasound performed?
A trained medical professional, such as a doctor, sonographer, or radiologist, conducts the ultrasound examination. Different methods are utilized depending on the specific body part under examination.
The ultrasound probe is a small handheld device that generates high-frequency sound waves. Although these sound waves are inaudible to the human ear, they bounce off various parts of the body, creating “echoes” that the probe detects. The echoes are then transformed into a dynamic image displayed on a monitor. Typically lasting between 15 to 45 minutes, ultrasound procedures are primarily conducted externally using the handheld probe, with a few involving the insertion of a small tool into the body.
Types of Ultrasound Scan
External Ultrasound
For external ultrasounds, the professional gently places the handheld probe on the skin, gliding it over the area that is being examined. Subsequently, a lubricating gel is applied to facilitate smooth movement. External ultrasound is most commonly used for examining the womb and heart.
Internal Ultrasound (Transvaginal Ultrasound)
Transvaginal ultrasound involves a probe inserted through the vagina or rectum to get a closer look at your ovaries, uterus or prostate glands. Internal examinations may cause some discomfort but there is no pain.
Endoscopic Ultrasound
In endoscopic ultrasound, a medical professional inserts the endoscope through the mouth to explore internal organs such as the stomach or oesophagus. The endoscope which is equipped with a light and ultrasound device on its tip is carefully inserted. It generates images via sound waves. Generally, to manage potential discomfort and pain caused by the endoscope, a sedative or local anaesthetic is administered.
Other new methods
Traditional ultrasound produces thin, flat and 2D images of the body. However, the evolution of ultrasound technology has enabled three-dimensional (3D) ultrasound. This innovation transforms sound wave data into 3D images, offering a more comprehensive view of the internal structures.
A specialized ultrasound technique known as Doppler ultrasound is a new method which focuses on analyzing the movement of substances within the body. Thus it empowers medical professionals to observe and assess the flow of blood through arteries and veins in the body.
Applications of Ultrasound Scan
Ultrasound’s versatility extends across a panorama of medical needs, shedding light on various conditions. Besides pregnancy testing, Ultrasound serves a diverse range of purposes, including assessing the brain, hips, and spine. It plays a crucial role in biopsies, aids in identifying heart-related issues, and facilitates the monitoring of post-heart attack damage.
The applications of ultrasound are
- Monitoring the well-being of a developing fetus
- Gain insights into the state of the uterus and ovaries during pregnancy
- Diagnosing gallbladder issues
- Assessing blood circulation
- Providing precision for guiding needles in biopsies or tumor treatments
- Monitoring breast lumps
- Exploring the thyroid gland
- Detecting problems concerning the genitals and prostate
Risks involved in Ultrasound
There are no known risks involved in ultrasound. Ultrasound does not expose you to radiation, it uses sound waves so it’s safer than other imaging techniques. It’s completely safe for the mother and fetuses during pregnancy
Ultrasound scan procedure are conducted in accredited medical facilities or laboratories under the guidance of qualified doctors or trained sonographers, ensuring adherence to safe practices. However, it’s important to note that places offering “keepsake” 3D or 4D ultrasound pictures or videos may not be safe, as they might not comply with the required safety standards.
Conclusion
Ultrasound Procedure has many perks, it’s non-invasive, safe and easier to perform which is why it’s the preferred diagnostic tool for doctors in detecting and detecting and tracking a myriad of conditions and its role in pregnancy is indispensable.
