The cost-utility of CT angiography and conventional angiography for people presenting with intracerebral hemorrhage.

ABSTRACT:

Objective

To determine the optimal imaging strategy for ICH incorporating CTA or DSA with and without a NCCT risk stratification algorithm.

Methods

A Markov model included costs, outcomes, prevalence of a vascular lesion, and the sensitivity and specificity of a risk stratification algorithm from the literature. The four imaging strategies were: (a) CTA screening of the entire cohort; (b) CTA only in those where NCCT suggested a high or indeterminate likelihood of a lesion; (c) DSA screening of the entire cohort and (d) DSA only for those with a high or indeterminate suspicion of a lesion following NCCT. Branch d was the comparator.

Results

Age of the cohort and the probability of an underlying lesion influenced the choice of optimal imaging strategy. With a low suspi
