deoxyhemoglobin

 [de-ok″sĭ-he´mo-glo″bin]
hemoglobin not combined with oxygen, formed when oxyhemoglobin releases its oxygen to the tissues.

de·ox·y·he·mo·glob·in

(dē-oks'ē-hē'mŏ-glō-bin)

Evidences about the impact of CMB after thrombolysis are finitude, and SWI is characterized with high sensitivity of CMB or any other types of cerebral hemorrhage for the character of identifying deoxyhemoglobin and hemosiderin; further studies are needed to confirm the predicting role of CMB or asymptomatic hemorrhage after thrombolytic therapy.
