Pelvic classification based on deep learning algorithm on clinical CT scans in Malaysian population

The estimation of biological sex and skeletal age is vital when dealing with skeletal remains. As human are sexually dimorphic, are present in the skeleton, markedly after the age of puberty. Age related changes also can be quantified in the skeleton, manifesting in the formation of skeleton to a...

The CT scans of 290 individuals (179 males and 111 females) which comprised an age range from 7 to 94 years old of the Malaysian population were analysed by GTM (Google Teachable Machine). The sample was collected at Hospital Universiti Sains Malaysia (HUSM) starting from 2009 until May 2023.

For age classification, each feature has been divided into two main groups which are age above 20 years old and age below 20 years old. The Phenice sex estimation method provides 98% of mean precision while 88.3% and 95% for mean sensitivity and mean specificity respectively. However, the Phenice age classification method is only applicable for sample age above 20 years old. It gives 97.75% of mean precision, 93.95% of mean sensitivity and 95.7% of mean specificity. For samples under 20 years old, the precision, sensitivity and specificity cannot be calculated as the result by Google Teachable Machine is error.
