BACKGROUND AND PURPOSE: There are limited indicators available to predict cerebral
vasospasm in patients with subarachnoid hemorrhage (SAH). The purpose of this study was …

BACKGROUND AND PURPOSE: After subarachnoid hemorrhage (SAH), vasospasm is
frequent and increases the risk of stroke and poor clinical outcome. The purpose of this …

Subarachnoid hemorrhage (SAH) causes dynamic changes in cerebral blood flow (CBF),
and results in delayed ischemia due to vasospasm, and early perfusion deficits before …

The aim of this prospective study was to assess the feasibility and diagnostic relevance of
repetitive dynamic (contrast-enhanced) CT measurements of cerebral blood flow (CBF) …

Introduction The aim of this study is to evaluate computed tomography perfusion (CTP)
during admission baseline period (days 0–3) in aneurysmal subarachnoid hemorrhage (A …

Introduction Dynamic perfusion computed tomography (PCT) has been established as a
diagnostic instrument for the detection of vasospasm after subarachnoid hemorrhage (SAH) …

Objective We investigated the ability of early alteration of cerebral perfusion–computed
tomography (PCT) parameters to predict the risk of vasospasm, delayed cerebral ischemia …

Purpose We sought to imitate angiographic cerebral circulation time (CCT) and create a
similar index from baseline CT perfusion (CTP) to better predict vasospasm in patients with …

OBJECTIVE: Angiographic cerebral vasospasm occurs in approximately 70% of patients
hospitalized after aneurysmal subarachnoid hemorrhage (SAH) and is associated with poor …

Object. This study was conducted for two purposes. The first was to determine whether a
combination of measurements of subarachnoid clot volume, clearance rate, and density …
