AIm: Computed tomography perfusion (CTP) has recently been used to identify regions of potential ischemia due to cerebral vasospasm, ... As the current gold standard, digital subtraction angiography (DSA) can straightforwardly and accurately diagnose anatomic narrowing of cerebral arteries. Endovascular treatment and/ or intra-arterial injection can then be performed in time … Accuracy test characteristics, agreement rates, kappa values, and bias indices were calculated.Performing validation methods for a new reference standard is an evolving and ongoing process because limitations and bias in the reference standard are identified. for confi rming the diagnosis of vasospasm and in a re-cent analysis of 597 studies it was found to be a safe meth-od. A treatment recommendation based on CTA was compared to actual treatment received.Final analysis included 34 patients. Used to predict the risk of cerebral vasospasm after SAH based on: 1. blood thickness 2. presence of IVH.

While there are many different techniques for evaluating PTV, the gold standard for diagnosis remains DSA.

Introduction: Cerebral vasospasm (CV) is one of the most dreaded complications in patients who survive acute subarachnoid haemorrhage (SAH), and conventional cerebral angiography (DSA) is the gold standard for its diagnosis.
