Swelling: An effusion is a medical term for swelling. The MRI is a sensitive tool that picks up even the slightest abnormality in a given area. A small effusion is a small amount of swelling in the joint. This could be due to a number of things, from arthritis to ligament and cartilage injury.

Knee MRI: Effusion is "water on the knee". This could be benign or caused by an internal derangement (ie: cartilage tear).
