Predictive Value of CTA Spot Sign on Hematoma Expansion in Intracerebral Hemorrhage Patients
Figure 4
This figure demonstrates the process of hematoma expansion and its secondary effects. Spot sign on CTA (computed tomography angiography) and CTP (computed tomography perfusion) and leakage sign on CTA are strong predictors of hematoma expansion. Utilizing spot sign in acute initial hemorrhage can help reduce secondary brain injury and inflammation and thus reduce morbidity and mortality associated with hematoma expansion.
