Definition

Noun: 1. A medical imaging procedure: Venography is a diagnostic technique that uses X-rays to visualize veins within the body. A contrast agent (dye) is injected into a vein to make it visible on the X-ray images.

Usage

Venography is used to diagnose conditions affecting the veins. * The doctor ordered a venography to check for a deep vein thrombosis (DVT). * Venography is a common method for mapping the venous system before certain surgeries. * Compared to an ultrasound, venography provides a more detailed image of the vein's structure.

Advanced Usage

• Contrast venography: This is the full technical term, specifying the use of a contrast medium.
  • Contrast venography remains the gold standard for diagnosing venous malformations.
• The procedure itself or the resulting image can be referred to as a venogram.
  • The radiologist reviewed the venogram from the lower limb venography.

Notes

Venography is an invasive procedure because it requires an injection. Non-invasive alternatives like Doppler ultrasound are often used first. The term is almost exclusively used in medical and clinical contexts.
