Physical movement of the patient (i.e. the inability of the person to stay still when the scan is being taken). This kind of motion causes a blur in the phase-encoded direction of the image. Periodic motion such as arterial pulsations, swallowing, breathing and peristalsis results in discrete and well-defined ghosts.
A bruise, also known as a contusion, is a type of hematoma of tissue, [3] the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration.

Like other haematomas, welts change their colors as they heal, which usually takes two to four weeks. The colors include purplish black, reddish blue, brown or yellowish green.

Fluid can be drained, including by inserting a drain surgically. Seromas can be prevented through careful surgery, and drains can be inserted before they form.
