Nuclear medicine, contrast angiography, and magnetic resonance imaging for evaluating vascular problems in the hand.

Techniques for imaging the vascular tree have undergone change and development. Nuclear imaging can lead to decisions concerning diagnoses of masses, while contrast angiography with digital subtraction gives a complete picture of the vessels. Magnetic resonance angiography is the most exciting advance. Completely noninvasive, it yields much the same information as conventional contrast angiography.
