The development of ultrasound imaging has been the most significant achievement in the field of diagnostic imaging.The word “ultra” means beyond.An ultrasound scan also refered to as a sonogram, diagnostic sonography and ultrasonography is a device that uses high frequency sound waves which is beyond audible range of human ear , but is used to create an image of some part of the inside of the body.In last one decade phenomenal advancement in technology and innovation in High Resolution sonography and color flow imaging have opened new areas of imaging which were considered to be gray areas.DNA Forensics Lab provides highly accurate Ultrasound Test at cost effective rates.
Unlike other imaging techniques ,ultrasound uses no radiation .For this reason,it is the preferred method for diagnosis.It only uses high frequency sound waves to capture live images from the inside of body .The reflected sound waves are called echoes. The amount of echoes produced will depend on the structural propertyof the various organs.
WHY AN ULTRASOUND
Your doctor may order an ultrasound if u r having pain, swellimg or other symptoms that require an internal view of ur organs like
- gall bladder
- blood vessels
Since the scan has no radiation so is useful to luk at the unborn child(fetal ultrasound)
Depends on the area or organ that is being examined
12 hrs fasting for abdominal ultrasound because undigested food can block the sound waves
Full bladder by drinking lots of fluid for pelvic ultrasound
