Ultrasound is a noninvasive diagnostic imaging test. It uses high-frequency sound waves to create real-time pictures of internal organs or other tissues, such as blood vessels. Ultrasound does not use any x-rays or radiation.

Your Results

When you first register with us, you will be invited to access SVCMI Patient, our patient app that enables our patients to securely access their images and reports.

See here for more information.

At the completion of your examination, you do not need to wait for images. You will receive the images into your SVCMI Patient app, approximately one hour after your scan is completed, and the report 4-6 days later. Your referring doctor will receive your results as soon as the report is finalised by our radiologist.

We recommend that you always return to your referring physician to discuss your results.

To download the app, go to your app store and select SVCMI Patient.

What to Expect

You may be asked to remove certain pieces of clothes or change into a gown. For the scan, you will lie on your side or back on a comfortable table. An ultrasound test usually takes 30-60 minutes , depending on the region of examination. A small amount of water-soluble gel will be applied to the area to be examined. The sonographer will move a transducer (probe) over the gel, using gentle pressure. You may be required to hold your breath for a few seconds to acquire higher quality images. If you experience any discomfort, please inform the sonographer.
