- ADC Level is Related to DWI Reversal in Patients Undergoing Mechanical Thrombectomy: A Retrospective Cohort Study
In acute ischemic stroke, the ADC value is independently associated with DWI reversal. Lesions with a mean ADC of ≥ 520 x 10-6 mm2/s are salvageable by mechanical thrombectomy, and DWI reversal areas regain neurologic function. The ADC value is easily assessed and is a useful tool to predict viable lesions.
- Perfusion Scotoma: A Potential Core Underestimation in CT Perfusion in the Delayed Time Window in Patients with Acute Ischemic Stroke
Ghost infarct core has been described to account for overestimating core infarct size in the early time period (<3 hours). The authors describe the phenomenon of underestimating core infarct size on CT perfusion in the later time period (>6 hours), which they have termed perfusion scotoma.
