Ultrasound imaging, also known as sonography, uses high-frequency sound waves to create real-time images of the inside of your body. Because ultrasound is highly effective at assessing soft tissues, it is often the very first step your doctor will take to determine the cause of your symptoms.
To perform the exam, a sonographer uses a small handheld probe (transducer) to send high-frequency sound waves, produced by piezoelectric crystals housed inside the probe, into the body and record the echoes that return. As these waves travel through the area being examined, they encounter structures with varying densities and hit boundaries between different tissue types, such as the transition from fluid to soft tissue, or soft tissue to bone. Some of the signal bounces back to the probe immediately, while the rest travels deeper until it reaches another boundary. A computer interprets the returning sound waves (or echoes) into a 2D grey scale image based on the velocity, intensity and direction of the echoes it receives.
The shape and intensity of the echoes depend on how different tissues reflect, transmit, or absorb the sound waves:
Ultrasound has been around for over sixty years and is considered safe since there are no known risks and it doesn’t use radiation. It’s one of the most ordered imaging exams since it’s versatile, portable, non-invasive and can provide real-time information about the area of concern.
Ultrasound has a variety of uses, despite being most often associated with pregnancy. It can be ordered to investigate pain, swelling, or other symptoms.
For example, ultrasound can help determine the composition of a lump, distinguishing between a cyst and a lesion. A cyst is a sac filled with fluid, which is mostly benign. A lesion is an area of solid tissue, which can be either benign or malignant. Ultrasound can often identify suspicious features, initiating further investigation, like further testing or a biopsy, as it is typically not used for a definitive diagnosis. Both cysts and lesions can be found in your skin, soft tissue, and organs.
Ultrasound is a standard part of prenatal care, providing images of the fetus or embryo’s viability and growth. Within the abdomen, ultrasound can help check for a myriad of conditions and diseases. Multiple still images are taken to represent the location and texture of each organ, as well as blood flow when required.
Ultrasound can also be used to assess muscles, ligaments, tendons, and the surface of bony structures for fluid or inflammation. Diagnostic quality can vary depending on factors such as patient mobility, physique and size. A musculoskeletal (MSK) ultrasound is often ordered for muscle, tendon, ligament, and nerve concerns such as symptoms in the ankle, elbow, knee, shoulder, or wrist. The dynamic nature of ultrasound is an advantage for accurate diagnosis, since the area in question can be evaluated while moving and as the patient performs the maneuvers that cause symptoms. MSK ultrasounds may be requested on their own or in conjunction with an X-ray to rule out a fracture.
Ultrasound imaging is covered under the Alberta and Saskatchewan Health Care Insurance Plans. It helps health care practitioners make a diagnosis and inform care decisions. Once your doctor has identified the need for an ultrasound, your doctor’s office may book an appointment for you or provide you with a number to call to book your appointment. You will also be given a requisition form and preparation instructions for your exam.
Some ultrasound exams require preparation before the exam. For example, for an abdominal ultrasound, you will be asked to fast and have nothing to eat or drink (except water) for six hours prior to your exam. For some obstetrical and pelvic ultrasounds, you will need to arrive with a full bladder. For more about prep instructions, visit Services – Mayfair Diagnostics.
Your images will be reviewed by a specialized radiologist who will compile a report that is sent to your doctor typically within two business days, sooner for urgent requests. Mayfair Diagnostics is owned and operated by over 55 radiologists who are fellowship-trained in many key areas, such as neuroradiology, body, cardiac, musculoskeletal, etc. This allows for an expert review of your imaging by the applicably trained radiologist.
Your images will be uploaded to a provincial picture archiving and communication system (PACS) – this technology provides electronic storage and convenient access to your medical images from multiple sources, including your doctor, specialists, hospitals, and walk-in clinics.
Your referrer will review the report from the radiologist and discuss next steps with you, such as a treatment plan or the need for further diagnostic imaging or lab tests to ensure an accurate diagnosis.
Mayfair Diagnostics has 13 locations across Calgary, one in Cochrane, and one in Regina, providing ultrasound services. For a list of our locations and how to book an exam, please visit radiology.ca.
