Proposal - Essay Example It is very important for the treatment of the ischemic stroke that the scope of the damaged made to be defined. Diagnostic requirements for imaging the patients with ischemic stroke changed due to the result of research made by National Institute of Neurological Disorder and Stroke (NINDS). A new treatment for ischemic lesions of the (MCA) middle cerebral artery territory was introduced. It is called Thrombolysis. A metanalysis was published and it summarizes the entire outcome for which Thrombolytic agents were used to treat severe ischemia in three to six hours (Kobayashi et al 2007). The result was significant decrease in patients with negative outcome after the treatment. However there was also higher threat of hemorrhage and death in the first ten days of treatment. At the increase of the time interval between the beginning of the stroke and thrombolytic treatment, the threat of death and hemorrhage also increases. The determining factor of the success of thrombolytic therapy de pends greatly on the earliest detection of the unfortunate event. The study shows that those patients that have been diagnosed as early as three hours from the onset have the greater positive outcome. Thus, the efficiency of the diagnostic imaging is of uttermost importance. It will ascertain the right patients for thrombolytic therapy so that severe complications could be avoided. For this reason the efficient diagnostic imaging should greatly help (a) leave out intracranial bleeding, (b) to determine which brain tissue is irreversibly affected and which is still has the good chance to recover, (c) and recognize stenosis or narrowing of the passage of the major extra and intracranial artery. On time restoration of blood flow to an organ or tissue may help prevent death of cell and reestablish normal function (Tomandl et al 2003). The one aim of the neuroimaging in ischemic stroke is to ascertain the tissue at risk of infaction (Murphy et al 2008). The aim of this
