Digital Imaging as a Possible Approach in Evaluation of Islet Yield

Blog Article

Digital image analysis (DIA) is a new method in Oval Casserole assessment of islet amount, which is expected to provide reliable and consistent results.We compared this method with conventional counting of small numbers of rat islets.Islets were isolated from 8 pancreases and counted in 24 samples in duplicate, first routinely by sizing according to estimated diameters under a calibrated reticule and then by processing of islets pictures taken by camera.As presumed, no significant difference was found in absolute numbers of islets per sample between DIA and conventional assessment.

Volumes of islets per sample measured by DIA were on average more than 10% higher than amounts evaluated conventionally, which was statistically significant.DIA has been shown to be an important method to remove operator Ski de fond - Accessoires - Piece de rechange bias and provide consistent results.Evaluation of only two dimensions of three-dimensional objects still represents a certain limitation of this technique.With lowering of computer prices the system could become easily available for islet laboratories.
