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
  • Screen for hepato-cellular disease
  • Detect hepatic metastasis and hematoma
  • Define cold spots as tumors, abscess, or cyst
  • Demonstrate splenomegaly
  • Monitor progression of the primary and secondary splenic disease and to eviled effectiveness of therapy
  • Evaluate spleen after abdominal trauma
  • Aid in diagnosis of pancreatitis, pseudocyst, and pancreatic carcinoma
  • Determine the size, shape, and position of kidneys, their internal structure, and perennial tissues
  • Evaluate and localize Urinary obstruction and abnormal accumulation of fluid
  • Assess and diagnose complications following kidney transplantation
  • Evaluate thyroid structure
  • Monitor the size of the thyroid gland during suppressive therapy
  • Evaluate fetal viability, position, gestational age, and growth rate
