Colour Ultrasound – Myth vs Facts
Myth: A coloured ultrasound always has coloured images like yellowish etc which is better than a black and white ultrasound.
Facts: Gray scale is the key to radiological imaging. Coloured images (eg. Yellowish or Pinkish) are actually a change of tint of the gray scale image. See the example below.
Many doctors give a black and white print out on thermal paper roll which discriminates the grey shades better as well as saves time.
A true coloured ultrasound is imaging of vessels (or of movement of fluid in certain cases eg. Urinary jet in Urinary bladder), where you can see red and blue colours on the ultrasound machine screen, that represent direction of flow. When colour mode is on, any movement will give red and blue colours and the doctor adjusts the technical factors to evaluate the region of interest properly. See the example below.
In layman terms: When you see red and blue colours in an otherwise black and white image on the machine screen, that’s when your doctor is using colour imaging to evaluate your particular region of interest. Print outs may still be black and white.
