NCT06093217

Brief Summary

The goal of this exploratory observational study is to assess the feasibility and real-world clinical impact of implementing Artificial Intelligence (AI) software for the detection of acute Pulmonary Embolism (PE) in patients who undergo Computed Tomography Pulmonary Angiogram (CTPA). The main questions that this study aims to answer are: \[Question 1\] What is the real-world impact of AI on the clinical outcomes and decision making by radiologists and clinicians in the management of acute PE? \[Question 2\] Is AI software for the detection of acute PE acceptable to use in clinical practice and do they have a favourable impact on clinical workload? \[Question 3\] Is it cost-effective to implement AI software for the detection of acute PE in clinical practice? Patients having a CTPA for the detection of acute PE will have their imaging analysed by AI software in combination with a human radiologist. Researchers will aim to compare the clinical and radiology specific outcomes with a retrospective cohort of patients who have had standard routine radiology reporting.

Study Arms (2)

Prospective Cohort: 'Live' Introduction of AI technology

Consecutive CTPAs, for patients with suspected acute PE, which have their imaging interpreted 'live' by AI technology. The radiologist will have ultimate responsibility for the report generated.

Device: Artificial Intelligence

Comparator Cohort: Standard Radiology reporting

Retrospective CTPAs, for patients with suspected acute PE, which have been reported by a human radiologist only. These CTPAs will not be interpreted by AI technology 'live' BUT undergo analysis to help assess the sensitivity, specificity, false negative, false positive rates of AI technology.

Device: Artificial Intelligence

Interventions

AI technology will generate a report with relevant key slice imaging identifying the presence of an acute pulmonary embolism and RV:LV ratio measurements to the radiologist
