Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
Hyperperfusion syndrome can occur in patients with preprocedural cerebral hemodynamic impairment who candidate for carotid stent. We investigated whether preprocedural measurement of cerebrovascular reserve (CVR) by using CT perfusion (CTP) with acetazolamide (ACZ) challenge could identify patients …

Lungenfunktion bei Säuglingen mit angeborenem Herzfehler
Angeborene Herzfehler mit pulmonaler Hyperperfusion führen im Säuglingsalter vor operativer Korrektur zu einer Überblähung der Lunge mit erhöhtem intrathorakalen Gasvolumen. Weiterhin haben diese Patienten in einem hohen Prozentsatz eine erniedrigte thorako-pulmonale Elastizität. <br>Diese …

Investigating white matter alterations and secondary neurodegeneration with MRI imaging and pathology in a mouse model of ischaemic stroke
… areas, with distinct patterns of hypoperfusion, hyperperfusion, inflammation, and structural degeneration. This work provides a foundation for future studies using spatial transcriptomic approaches to define the molecular correlates of these remote neuroimaging and pathophysiological changes.
