Lung cancer screening encompasses a pathway that includes several integral elements. It starts with the active recruitment of individuals and their risk assessment. The pathway continues into radiology, with the actual scanning using low dose computed tomography (LDCT), as well as standardized reporting that focuses on the follow up of both lung nodules and incidental findings. At the end of the pathway is the seamless integration into a diagnostic assessment program for confirmation and timely and appropriate treatment of the detected lung cancer.
High quality, and quality assurance of the radiology performance is the central piece in this pathway, to decrease the harm from radiation and false positives. Since lung cancer screening is most often a newly established program in an institution, this presents a unique opportunity to build robust quality standards for radiology. Radiology quality assurance comes with requirements regarding acquisition, interpretation and reporting of the low-dose computed tomography (LDCT) scans.
The facility standards need to provide equipment that does allow low dose data acquisition. Scanning protocols need to be defined, and protocol compliance needs to be assured, radiation exposure needs to be regularly measured with phantoms, and image storage needs to be properly identified.
Personnel requirements cover both the technologists and the reporting radiologists. Both have to provide the necessary training and certification. Radiologists need to document their ongoing experience in chest reporting, participate in a workshop or alternative training regarding nodule follow up, and get familiar with the respective reporting template. Radiologists training programs have received positive feedback on content, their goal is to increase confidence in reading lung cancer screening LDCTs and appropriate recommend follow up for screen-detected nodules. Complex cases are collected and their discussion fosters mutual learning.
Ongoing quality assurance measures include peer review and double reads, to minimize false positive. An adjudication process can provide expert opinion and support learning where consensus can not initially be reached. Report completeness should be confirmed with regular audits.
All these requirements should be available and met by a facility planning to engage in lung cancer screening using LDCT. All above standards are available; they need to be monitored, must be met at baseline and during tailored annual assessments, ensuring compliance across screening sites.
In summary, the implementation of a robust quality assurance program assures a high standard around the radiology workflow, from LDCT scanning to image interpretation and follow up recommendations. Radiologist training programs, centre minimum requirements, and standardized reporting can ensure that quality standards are consistently high
