Related topics: Medical Imaging Medical tests & imaging
Ultrasound is a non-invasive medical procedure that uses high-frequency sound waves to capture real-time images to monitor pregnancies, assess organs and soft tissues, and evaluate blood flow in blood vessels. This procedure can look at the structures of your body without the use of radiation or contrast dye.

During the ultrasound scan
Room set-up
You will be taken to an examination room and asked to lie down on a stretcher. The room will typically be dimly lit to help the sonographer see the monitor and the images that are taken during the test. While the sonographer is scanning, they will not be able to turn the screen towards you.Gel application
A water-based gel will be applied to the area of your body that will be examined. This gel helps the ultrasound probe/transducer make better contact with your skin and allows sound waves to pass through more easilyComfort
Ultrasound examinations are generally painless. You will feel slight pressure as the sonographer moves the ultrasound transducer, but it is usually well-tolerated. -
Getting your scan results
The sonographers are registered and trained to perform your test. Radiologists are physicians who are qualified to read and interpret the images that the sonographer obtains during the test.
- For this reason, sonographers cannot discuss the results with you. The final report from the radiologist will be sent to your referring health care provider.
- The images captured during the ultrasound examination will be read and interpreted by a radiologist. Afterwards, they will send the final report to your health care provider with any findings and may provide recommendations.
The final report takes 2 to 3 business days to be sent to your referring health care provider. Urgent results will be phoned to your health care provider as soon as possible.

What causes the noise in the MRI scanner?
The loud noises are caused by the operation of the magnetic coils in an MRI scanner machine.
When the MRI machine takes images, it uses powerful electromagnetic pulses that cause the coils and magnets to turn on and off rapidly. This creates vibrations and mechanical movements that result in the loud knocking, buzzing, or tapping sounds.
Different sequences of images create different patterns of sound. The loud noises are part of the MRI technology and are not a sign of a problem or malfunction. The MRI machines are designed to minimize the noise levels as much as possible, however, it can still be quite loud.
Most MRI centers provide earplugs, headphones or music to help reduce the noise and make the experience more comfortable.
