"The oxygenation state of haemoglobin and its location (whether it is contained within red blood cells or diffused in the extracellular space) has a tremendous effect on the imaging effects of blood. The three haemoglobin states to be considered are oxyhaemoglobin, deoxyhaemoglobin and methaemoglobin."
"Eventually, haemosiderin and ferritin (both strongly paramagnetic) are ingested by monocytes and macrophages andresults once more in unevenly distributed paramagnetic effects and signal loss 2."
"subacute and chronic blood appears hypointense and blooms on MRI T2* weighted sequences (e.g. susceptibility weighted imaging (SWI))"
