Photoacoustic mesoscopy visualises vascular architecture at high-resolution up to ~3 mm depth. Despite promise in preclinical and clinical imaging studies, with applications in oncology and dermatology, the accuracy and precision of photoacoustic mesoscopy is not well established. Lina undertook a detailed phantom and in vivo study to understand the sources of artefacts and variability in photoacoustic mesoscopy, leading to an important set of recommendations for users of such systems.
