VRV is a system developed and designed by Daikin Industries and means âvariable refrigerant volumeâ. Daikin protected the term VRV so other manufacturers use the term VRF âvariable refrigerant flowâ.In principle they both work the same and are extremely efficient, reliable, energy saving ways to heat and cool all types of buildings with minimum installation time or disruption.aikin protected the term VRV so other manufacturers use the term VRF âvariable refrigerant flowâ.

Magnetic resonance venography (MRV) is an accurate, noninvasive technique used to detect deep vein thrombosis. This application of MRI provides images of blood flow in diseased and normal veins. In patients who are allergic to iodinated contrast medium, MRV is used in place of venography or CT venography. MRV is particularly useful for visualizing vascular abnormalities, thrombosis, and other pathology. MRV can be accomplished with a contrast-enhanced (CE) or nonâcontrast-enhanced method. Special imaging sequences allow the visualization of moving blood within the venous system.
