title: Multifractal spectrum of chorionic villi: a novel approach.
abstract: OBJECTIVE
  To measure the multifractal dimension in histopathology sections of chorionic villi to study its role to distinguish between normal chorionic villi and hydatidiform mole.
  
  
  METHODS
  Multifractal spectrum was measured in 10 each cases of normal chorionic villi and hydatidiform mole. The values of alpha max and alpha min and their difference Delta alpha (alpha max--alpha min) were recorded in each case. The data for these groups were compared.
  
  
  RESULTS
  The mean +/- SD of alpha max, alpha min, and Delta alpha (alpha max--alpha min) of normal chorionic villi were 2.6335 +/- 0.16109, 1.6975 +/- 0.04435, and 0.9360 +/- 0.12725, respectively. Whereas the mean +/- SD of alpha max, alpha min, and Delta of hydatidiform moles were 2.3196 +/- 0.11937, 1.6209 +/- 0.06208, and 0.7000 +/- 0.08350, respectively. The mean alpha max, alpha min, and Delta alpha of normal chorionic villi were much higher than for hydatidiform mole. Independent sample t-test shows significant difference (p < 0.001) in alpha max, alpha min, and Delta alpha of normal chorionic villi and hydatidiform mole.
  
  
  CONCLUSIONS
  Multifractal dimension was significantly different in normal chorionic villi and hydatidiform mole.
