The Royal College of Radiologists’ 2025 Clinical Radiology Census presents a worsening workforce picture across UK clinical radiology. The census received responses from all Clinical Directors leading radiology departments and covers diagnostic and interventional radiology. Clinical radiologists interpret scans, monitor disease and injury and perform minimally invasive procedures that support diagnosis and treatment planning across patient pathways. The UK now has a 32% shortfall of consultant clinical radiologists, equivalent to more than 2,300 whole time equivalent doctors. Without action, the shortfall is forecast to reach 40% by 2030. Demand for complex imaging is rising faster than workforce growth, while recruitment freezes, rising outsourcing costs and pressure on training capacity are limiting departments’ ability to maintain stable services.
Demand Rises Faster Than Capacity
Clinical radiology capacity continues to grow, but not fast enough to match the pace of imaging demand. The substantive consultant workforce expanded over the past year, and the NHS has added consultant and Specialty and Associate Specialist radiologists over the past five years. That growth remains far below the level required to close the current workforce gap.
The pressure is not only a matter of volume. Diagnostic imaging has increased across the UK, with complex modalities such as CT, MRI, PET, SPECT and nuclear medicine forming a growing share of activity. These scans are largely reported by clinical radiologists and often require more time and expertise than simpler imaging. The result is a heavier and more complex workload for departments already operating below required staffing levels.
The workforce is also unevenly distributed. Small acute hospitals face the largest average shortfalls, while specialist and teaching hospitals are better placed. Regional variation is substantial, with some areas facing much deeper gaps than others. The UK also has fewer radiologists per population than the OECD average and the European Union average. London is the only UK region above the OECD average, leaving many departments with limited capacity to absorb rising demand.

Patient Care and Training Face Strain
Workforce shortages are affecting patient care. Clinical Directors identify delays caused by staff shortages as a factor in worsening patient conditions. Many departments also face backlogs in scan reporting, with diagnostic imaging studies exceeding the target reporting timeframe. Waiting times for scans remain a further pressure across the NHS.
The impact extends beyond reporting. Radiologists contribute to multidisciplinary team meetings, clinical liaison, request vetting, teaching, supervision, quality improvement, research and service development. These activities support safe and effective care, but rising demand can erode the time available for them. Reporting alone accounts for nearly half of consultant clinical radiologists’ working time, while multidisciplinary work and clinical liaison take a substantial further share.
Training is under strain despite strong interest in clinical radiology careers. Entry posts continue to fill, and competition for places has increased substantially over time. The main constraint is not recruitment interest, but capacity to train. Clinical Directors express concern that shortages reduce training opportunities and limit supervision. Longer training periods, less than full time working and vacant training slots also reduce the number of doctors moving through the pipeline.
Interventional radiology faces similar workforce pressure, with uneven access across the UK. Many services do not provide round-the-clock cover, and some areas have limited access to urgent image-guided procedures. Clinical Directors identify delayed or cancelled interventional radiology procedures, delayed discharge and patient deterioration as consequences of workforce shortfalls.
Departments Rely on Costly Workarounds
Recruitment freezes have become a major barrier to workforce growth. The share of radiology departments affected by freezes doubled in one year. Some freezes apply only to new posts, while others also prevent vacant roles from being filled. These restrictions limit the ability of departments to respond to rising demand, even where local service needs are clear.
Departments are using outsourcing, insourcing and ad hoc locums to manage excess reporting demand. Spending on these measures reached £362 million (€420 million) in 2025, exceeding the cost of the consultant capacity required to close the current shortfall. Outsourcing accounts for the largest share of this spending. Clinical Directors also identify concerns around cost, communication with referrers, report quality and the extra work created when outsourced imaging requires review within local departments.
Technology has not yet released substantial capacity. Artificial intelligence is now used in most radiology departments, especially for image interpretation, but its effect on workload remains limited. In many departments, AI has no reported impact on workload or adds work. Report drafting is the least common use case, although departments using it are more positive about its potential workload effect.
Departments are also adopting productivity initiatives, including changes to pathways, reporting practices and administrative processes. These measures can support efficiency, but they do not remove the underlying workforce gap. The pressure on departments reflects a mismatch between increasing imaging demand and the available clinical workforce needed to deliver safe reporting, interventional services, supervision and clinical leadership.
The UK radiology workforce faces a widening gap between demand and capacity. The shortfall affects reporting times, patient care, interventional access, training and departmental finances. Smaller hospitals and some regions carry a heavier burden, while recruitment freezes and reliance on temporary workarounds limit long-term recovery. Technology and productivity measures may support services, but current use has not offset the workforce deficit. Stable radiology services depend on sustained workforce growth, protected training capacity, reduced reliance on outsourcing and better alignment between imaging demand and available clinical expertise.
