Health Check and Diagnostic Imaging
Ultrasound Scan

Theory
Ultrasound, which is a sound wave of frequency more than 20 kHz, is beyond hearing range of human. It can go underneath the skin, and reflect images of muscles, organs and tissues. Being painless, harmless, no radiation and no contrast is used, ultrasound scan is then believed to be the safest medical imaging.

Introduction



Siemens ACUSON S2000™ Ultrasound System uses Acoustic Radiation Force Impulse (ARFI) technology and Virtual Touch™ applications to provide clinical images which show the stiffness and thickness of different tissues with incredible clarity and detailed resolution. In addition, eSie Touch Elasticity Imaging Technology has a high sensitivity to differentiate stiff and soft tissues in order to obtain a clearer image.

Ultrasound Imaging is operated by specialist to offer our patients a worry-free check-up, which increases the efficiency and time for diagnosis.





Body parts that can be imaged

Examination Process
During the process of Ultrasound Scan, radiologists or radiographers will put ultrasound gel on body parts needed for imaging, and slide the transducer on those body parts. Ultrasound does not have ionization radiation. Patients may need to hold their breath for several seconds or turn around for convenient scanning. It usually takes 15 minutes to an hour, depending on number of body parts need to be scanned.

Precautions
Ultrasound of Upper Abdomen
