Data from: Automated CT perfusion imaging for acute ischemic stroke: pearls and pitfalls for real world use
Recent positive trials have thrust acute cerebral perfusion imaging into the routine evaluation of acute ischemic stroke. Updated guidelines state that in patients with anterior circulation large vessel occlusions presenting beyond 6 hours from time last known well, advanced imaging selection including perfusion based selection is necessary. Centers that receive acute stroke patients must now have the capability to perform and interpret CT or MR perfusion imaging, or provide rapid transfer to centers with the capability of selecting patients for a highly impactful endovascular therapy, particularly in delayed time windows. Many stroke centers are quickly incorporating the use of automated perfusion processing software to interpret perfusion raw data. As CT perfusion is being assimilated in real world clinical practice, it is essential to understand the basics of perfusion acquisition, quantification and interpretation. It is equally important to recognize the common technical and clinical diagnostic challenges of automated CTP including ischemic core and penumbral misclassifications that could result in underestimation or overestimation of the core and penumbra volumes. This review highlights the pitfalls of automated CT perfusion along with practical pearls to address the common challenges. This is particularly tailored to aid the acute stroke clinician who must interpret automated perfusion studies, in an emergency setting to make time-dependent treatment decisions for acute ischemic stroke patients.
Data from: Can perfusion CT unmask postictal stroke mimics? A case-control study of 133 patients
OBJECTIVE: To study the diagnostic value of volume perfusion CT (VPCT) in patients with transient focal neurological deficits following and during epileptic seizures, that mimic symptoms of stroke. METHODS: a retrospective case-control study was performed on 159 patients that presented with a seizure and received an emergency VPCT within the first 3.5 hours of admission, after being misjudged to have an acute stroke. The reference test was a clinical-based, EEG-supported diagnostic algorithm for seizure. RESULTS: We included 133 patients: 94 stroke-mimicking cases with postictal focal neurological deficits ("Todd's phenomenon", n=67) or ongoing seizure on hospital admission ("ictal patients", n=27), and 39 postictal controls without focal neurological deficits. Patients with Todd's phenomenon showed normal (64%), hypo (21%)- and hyperperfusion (14%) on early VPCT. Ictal patients displayed more hyperperfusion compared to postictal patients (p=0.015). Test sensitivity of hyperperfusion for ictal patients is 38% CI [20.7-57.7], specificity 86% CI [77.3-91.7], positive predictive value (ppv) is 42% CI [27.5-58.7], the negative predictive value (npv) 83% CI [78.6-86.9]. A cortical distribution was seen in all hyperperfusion scans, compared to a cortico-subcortical pattern in hypoperfusion (p<0.001). A history of complex focal seizure and age were associated with hyperperfusion (p= 0.046 and 0.038, respectively). CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that VPCT accurately differentiates ictal stroke mimics from acute ischemic stroke. CONCLUSION: VPCT can differentiate ictal stroke mimics with hyperperfusion from acute ischemic stroke, but not postictal patients who display perfusion patterns overlapping with ischemic stroke.
