Ultrasonography| Indications



Ultrasonography refers to a procedure where a focused beam of high-frequency sound waves passes into the body, creating echoes that vary with changes in tissue density.

When echoes are converted to electric energy and amplified by a transducer, they appear on an oscilloscope screen as a pattern of spikes or dots. This pattern reveals the size, shape, and position of an organ.

Indications for Ultrasonography

  • Confirm the diagnosis e.g cholelithiasis
  • Distinguish between obstructive and non-obstructive jaundice

  • Determine the size, shape, and position of kidneys, their internal structure, and perennial tissues
