Diagnostic Modalities

An ultrasound scanner uses high frequency sound waves to create an image of the internal of the body. It is one of the safest types of scan as it can be used on pregnant women. During the scan, a small transducer is moved over the skin. This sensor is able to project and detect its own sound waves, which bounce off from different parts of the body. A computer then organises the reflected waves into a dynamic picture in which the radiologist uses to help make a diagnosis. The scan is usually done by a sonographer, but some doctors are trained to be able to do the scan too.


Before your appointment

Once we’ve received your referral and have booked a time slot for your scan, you’ll receive a confirmation with all the details of your appointment. Some ultrasound scans may require preparation, which you will be told about before your appointment.

When you arrive

When you arrive at Crawfurd hospital ,you’ll be checked in by a staff at our reception on the ground floor. You’ll be introduced to the Sonographer who will show you to the ultrasound room, explain the procedure to you and answer any questions about the scan. For some scans you might need to change into a gown; if this is the case you will be shown to a changing room where you can get changed and leave your valuables.

During your appointment

In the ultrasound room you will be asked to sit or lie down on a bed. The sonographer uses a water-based gel to help the sensor sweep across the skin, which help to generate a clear image. It is easily  wiped off after the scan.

The sonographer will move the transducer over your skin, during which you will be able to see the live images on the ultrasound machine. The sonographer will be taking screenshots to help the radiologist write up a report after your appointment.

After your appointment

After your scan, you can collect your valuables from the changing room, and go back home. The report will be ready within 24hrs and your referring physician will have the report then. He will then arrange a time for you to see him to discuss about your scan.
