The thrombolysis in cerebral infarction scale otherwise known as the (TICI) scale is an important outcome measure to evaluate the quality of endovascular stroke therapy. The TICI scale is ordinal and observer dependent, so this means it may not result in the best prediction of patient outcome and can also provide an inconsistent reperfusion grading.  Carmen Lahiff Jenkins Managing Editor of the International Journal of Stroke spoke to Drs Haryadi Prasetya and Manon Kappelhof from Amsterdamn University Medical Centre two of the author group who submitted the article qTICI: Quantitative assessment of brain tissue reperfusion on digital subtraction angiograms of acute ischemic stroke patients. In this podcast we look at the authors investigations into  qTICI and eTICI using image processing techniques based on the TICI methodology to develop better quality reperfusion grading.  The International Journal of Stroke is the flagship publish of the World Stroke Organisation  qTICI: Quantitative assessment of brain tissue reperfusion on digital subtraction angiograms of acute ischemic stroke patients
