Objectives: To synthesise existing evidence for the diagnostic accuracy of chest radiographs to detect lung malignancy in symptomatic patients presenting to primary care. Methods: A systematic review was performed and reported in accordance with the PRISMA framework, using a protocol prospectively registered with the PROSPERO database (CRD42020212450). Nine databases were searched for relevant studies. Data were extracted and chest radiograph sensitivity and specificity calculated where possible. Risk of bias was assessed using a validated tool. Random effects meta-analysis was performed. Results: Ten studies were included. Sensitivity meta-analysis was performed in five studies which were not the high risk of bias, with summary sensitivity of 81% (95% CI: 74–87%). Specificity could be calculated in five studies, with summary specificity of 68% (95% CI: 49–87%). Conclusions: The sensitivity of chest radiographs for detecting lung malignancy in primary care is relatively low. Physicians and policymakers must consider strategies to attenuate the possibility of false reassurance with a negative chest radiograph for this significant pathology. Options include widening access to cross-sectional imaging in primary care; however, any intervention would need to take into account the medical and financial costs of possible over-investigation. Prospective trials with long-term follow-up are required to further evaluate the risks and benefits of this strategy. Advances in knowledge: The chest radiograph has a sensitivity of 81% and specificity of 68% for lung malignancy in a symptomatic primary-care population. A negative chest radiograph does not exclude lung cancer, and physicians should maintain a low threshold to consider specialist referral or cross-sectional imaging.

Plain film radiography is often the first imaging modality employed in the assessment of patients with a rheumatological condition. More recently this has been superseded by cross-sectional imaging, in particular ultrasound and MRI, which have improved sensitivity in detection of early disease when compared with plain film imaging. However, there remains a role for conventional radiography in both the initial diagnosis and monitoring of disease progression. A standard approach to assessing radiographs in the context of arthropathy is usually employed by radiologists; by following this structured review a diagnosis or narrow differential may be reached on plain film imaging alone. Plain film radiograph findings of the most common rheumatological disorders are covered in detail in this chapter including osteoarthritis, the inflammatory arthritides, and crystal arthropathy. Findings in the connective tissue disorders are then covered, followed by less commonly encountered conditions such as SAPHO, neuropathic arthropathy, and haemochromotosis.
