BACKGROUND AND PURPOSE: In recent years, the role of CTA and CTP for vasospasm
diagnosis in the setting of ASAH has been the subject of many research studies. The …

PURPOSE: To evaluate the utility of perfusion CT (PCT) combined with CT angiography
(CTA) for the diagnosis and management of vasospasm, by using conventional digital …

Background: The purpose of this study was to compare simple visual grading of perfusion
CT (PCT) maps to a more quantitative, threshold-based interpretation of PCT parameters in …

Introduction Cerebral vasospasm (CV) is one of the most dreaded complications in patients
who survive acute subarachnoid haemorrhage (SAH), and conventional cerebral …

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

BACKGROUND AND PURPOSE: Digital subtraction angiography (DSA) is the standard of
reference for detecting cerebral vasospasm after subarachnoid hemorrhage (SAH). CT …

The current role of CT perfusion (CTP) imaging in the diagnosis and treatment of vasospasm
in the setting of aneurysmal subarachnoid hemorrhage is discussed in this article, with …

Purpose: To evaluate the accuracy of multidetector-row CT angiography (CTA) for the
diagnosis of large-vessel vasospasm following subarachnoid hemorrhage by comparison to …

Object The goal of this study was to assess the accuracy of the routine clinical use of
transcranial Doppler (TCD) ultrasonography and SPECT in predicting angiographically …

BACKGROUND AND PURPOSE: We investigated the association of multisection CT
angiography (MSCTA) and perfusion CT (PCT) for the characterization of vasospasm …
