Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Blood pool agents (BPAs) are a class of magnetic resonance angiography contrast agents. [ 1 ] [ 2 ] Blood pool agents (also known as intravascular contrast agents) are differentiated from other contrast agents due to their high molecular weight and higher relaxivities . [ 3 ]

When the heart stops functioning and is no longer agitating the blood, heavy red blood cells sink through the serum by action of gravity. The blood travels faster in warmer conditions and slower in colder conditions. Livor mortis starts within 20–30 minutes, but is usually not observable by the human eye until two hours after death. The size ...

Blood stasis is also described by practitioners of TCM in terms of yin deficiency, qi deficiency and qi stagnation.
Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities. If weakened, they may fail to close properly which leads to backwards blood flow/blood pooling. This can lead to slower blood flow in the veins. [8] Ultrasonography-Doppler ultrasound
