- CT angio used in the diagnosis of PE has increased due to recent studies
- The CT is done with intravenous contrast through a peripheral IV
- Studies suggest a wide range of accuracy from 98% to as low as 53%

- CT has a 90% negative predictive value indicating that negative results are more accurate [17]
- With any positive test results, clinical correlation should also be addressed
