"There are different types of decision tree model algorithms. Some of these algorithms have been used for radiology image classification and thus appear the radiology literature ( including CART 1 and CHAID 2 ) or radiology related computer science literature ( ID3 3,4). In contrast to many methods of machine learning, decision tree models utilise heuristics and are therefore comprehensible."
