How should I prepare for an Ultrasound?
- Wear comfortable, loose-fitting clothing
- Depending on the type of ultrasound exam you have, you will be asked to:
- Refrain from eating or drinking for up to 12 hours before your appointment, or
- Drink up to six glasses of water two hours prior to your exam and avoid urinating. This ensures a full bladder when the exam begins
What should I expect during this procedure?
During:The examination usually takes less than 30 minutes. After being positioned on the exam table, a clear gel is applied in the area being examined; it may feel a bit cold. The gel helps the transducer make contact with the skin. The technologist firmly presses the transducer against the skin and moves it back and forth to image the area of interest.
Generally, the technologist is able to review the ultrasound images in real-time. Alternatively, when the examination is complete and the gel is wiped off, you may be asked to dress and wait while the ultrasound images are reviewed, either on film or monitor.
A catheter approximately the size of a pen tip is guided under fluoroscopy into the desired vessels in your liver. Ionizing radiation via millions of tiny glass beads is then delivered into the tumor.
