WHAT IS ULTRASOUND?
Ultrasound imaging, also called ultrasonography, uses sound waves to produce pictures of the inside of the body. When the sound waves strike an object, they bounce back and produce echoes. By measuring these echo waves, it is possible to determine the distance of the object, its size, shape and consistency (whether the object is solid, filled with fluid or both). Because ultrasound images are captured in real-time, they can show the structure and movement of the body’s internal organs, as well as blood flowing through blood vessels or movement of joints or tendons in the musculoskeletal system.
IS ULTRASOUND HARMFUL?
Ultrasound does not use ionizing radiation so there is no radiation exposure during an ultrasound exam. No studies in humans have shown ultrasound to have harmful effects.
WHAT CAN I EXPECT?
- A clear water-based gel is applied to the area of the body being studied to help the transducer make secure contact with the body.
- The ultrasound technologist presses the transducer firmly against the skin in various locations, sweeping over the area of interest or angling the sound beam to better see an area of concern.
- In some ultrasound examinations, such as transrectal and transvaginal, the transducer is inserted into a natural opening in the body.
HOW CAN I PREPARE FOR A ULTRASOUND EXAMINATION?
- The steps you will take to prepare for an ultrasound will depend on the area or organ that is being examined. It is important to follow your doctor’s instructions and ask any questions you may have before the procedure.
- Fasting required (Allowed to drink water)
- Ultrasound Abdomen
- Fasting and full bladder (Allowed to drink water)
- Ultrasound abdomen & pelvis
- Full bladder (No fasting required)
- Ultrasound pelvis
- Ultrasound kidney ureters and bladder
- No Fasting required
- Ultrasound Neck/Thyroid
- Ultrasound Breast
- Ultrasound Scrotum
- Ultrasound extremities. Eg: Shoulder, forearm, hand, calf, foot etc.
- Ultrasound doppler arteries or veins
HOW AND WHEN DO YOU GET THE RESULTS?
- Ultrasound images are stored as electronic data files (PACS) and are usually reviewed on a computer screen. Your doctor will view the report through PACS once it is interpreted and approved by the radiologist.
- Your scan results will be reported within one (1) working day. However, urgent scans are reported within 4 hours.
- Reports and DVD copies of the Ultrasound images will be provided upon request only. Please inform the Imaging receptionist (front desk) to prepare it in advance should you wish to collect it after consultation. Preparation of the DVD will take approximately 15 minutes.
HOW DO I MAKE AN APPOINTMENT?
All outpatients going for ultrasound examination are required to make an appointment prior to the examination. Your appointment can be made through your referring doctor.
Our operating hours are from 8:30am to 4:30pm on weekdays and 8:30am to 1:00pm on Saturdays.
