Colour vision deficiency and perfusion brain scans

Colour vision deficiency (CVD), more colloquially known as colour blindness, impairs the perception and differentiation of various colours. CVD affects 1-6% of the population including medical professionals. CVD has been negatively associated with how medical staff recognise abnormalities in various disciplines, including histopathology and microscopy. Recent advances in treatment delivery have seen the increasing use of CT perfusion and colour maps in the management of acute stroke. The impact of CVD on interpretation of these colour perfusion maps has not been explored. It is possible that certain colour palettes may pose a problem for clinicians with CVD and if clinicians with CVD are less good at interpreting certain colour maps, this could directly impact on patient care. The colour palettes used in perfusion maps could be adjusted to accommodate professionals with CVD if a significant difference in interpretation is identified.

色觉异常（Colour Vision Deficiency，简称CVD），俗称色盲，会削弱个体对多种色彩的感知与分辨能力。全球约1%至6%的人群受其影响，其中包括医疗从业者。已有研究表明，色觉异常会对医疗人员在多个学科领域识别异常状况产生负面影响，涵盖组织病理学与显微观测场景。随着治疗手段的近年进展，CT灌注成像与色彩映射图在急性脑卒中诊疗中的应用日益广泛，但目前尚未有研究探讨色觉异常对这类灌注色彩映射图解读的影响。部分色彩调色板可能会对色觉异常临床医师造成解读障碍；若此类医师对特定色彩映射图的解读能力偏弱，则可能直接对患者诊疗产生不利影响。若经研究确认解读能力存在显著差异，可通过调整灌注成像所用的色彩调色板，以适配色觉异常的医疗从业者。
