Early detection is crucial to optimise treatment outcomes and minimise ulceration or gangrene and possible subsequent amputations. This systematic review evaluated the diagnostic significance and clinical utility of infrared thermography (IRT) and hyperspectral imaging (HSI) as non-invasive, contactless techniques for PAD and chronic limb-threatening ischaemia assessment. Infrared thermography assesses blood perfusion by detecting temperature changes in limbs and HSI can be utilised to evaluate oxygen saturation, and deoxyhaemoglobin and oxyhaemoglobin concentrations in superficial tissue.</p><p><strong>Methods: </strong>After a comprehensive PubMed literature search, a total of 15 articles were included in the final analysis: eight studies utilising IRT for circulation assessment, six studies employing HSI, and one study combining the two.
