Pulmonary CTA is a commonly performed study and the radiologist's role is not limited to simply producing a report. The process from identifying the appropriate patients who will benefit from the study to improving performance in the radiology department requires the radiologist's involvement, expertise, and leadership. The focus of this narrative review is to highlight the different steps and the ways to improve the quality in the assessment of thromboembolic disease where the radiologists can have an impact. This article provides an update on the commonly used and more recently published clinical decision tools, specific parameter adjustments of pulmonary CTA for more challenging patients and potential improvement for the radiology department.
