Can venous varicosity be measured by CT?
Venous varicosities can undergo CT imaging, but generally, it's best to avoid injecting medication into the varicose veins. If the varicosities are in the lower limbs, a routine ultrasound examination is usually sufficient. To perform venous imaging with CT, medication is typically administered through the upper limbs. It moves through the general circulation, enters the arteries, reaches the peripheral tissues, and then flows back through the veins to allow imaging of the lower limb veins. This process is time-consuming, laborious, and costly; therefore, CT is generally not used to detect lower limb venous varicosities. However, CT can be used to examine venous abnormalities in other areas, such as problems with abdominal veins.
