| Outline of Research at the Start |
褥瘡の肉芽組織の評価は，創面を占める良性肉芽の割合で点数化されている．肉芽が良性か不良かの判断は主観的なもので，評価者により評価がことなることがある。そこで本研究では，褥瘡の肉芽組織の病理組織所見，肉眼的所見と触診の所見，超音波診断検査の所見を統合し，エコーによる肉芽組織の客観的評価方法を確立し，自動判別システムを構築することを目指す．

| Outline of Final Research Achievements |
This study validated a method to quantitatively assess the condition of granulation tissue as benign or bad granulation using echo. First, the state of the granulation tissue was classified histopathologically and its characteristics were extracted. The granulation tissue was characterised by a low number of blood vessels, no fibrin matrix or angiogenesis on the surface of the granulation, and no myofibroblast layer in the underlying layer. For the echo evaluation, the images of the pressure sore area of interest were extracted from the echo images of the pressure sore and a histogram was calculated. The frequency of occurrence of each intensity value was normalised by image size and compared for each site. The results showed that there were significant differences in the mean and standard deviation of the histograms of the pressure ulcer and surrounding areas compared with normal areas in the echo images.
