Quality Standard for Imaging (QSI)
The Quality Standard for Imaging (QSI) sets out what high‑quality imaging services should look like in practice. Jointly developed by the Royal College of Radiologists and the College of Radiographers, it brings together clinical expertise, professional leadership and patient insight to define clear, practical expectations for safe, effective and consistently high‑quality care.
Designed for use within medical imaging services, QSI provides a clear framework for measuring and improving quality. The standards describe what is expected of a well‑run imaging service and support best practice across patient care and safety, staff wellbeing, and continuous quality improvement.
The Colleges support services to meet the standards through membership of the QSI Hub and a formal assessment process, with successful services awarded the QSI Quality Mark in recognition of their commitment to quality improvement.
QSI Quality Mark Scheme
The Colleges' QSI Quality Mark scheme is designed to focus on quality improvement for imaging services for the benefit of both patients and our members and engages imaging services in continuous quality improvement through formal peer review.
Quality Standard for Imaging
Developed collaboratively by the Royal College of Radiologists and the College of Radiographers, The Quality Standard for Imaging (QSI) is an ongoing joint enterprise between the two organisations. The standards are written by imaging professionals, informed by consultation with representatives from across the imaging workforce, alongside lay and patient representatives.
