Final--Result

It turns out that most abstracts have similar structure of the corresponding introduction. The portion of the length of each move is similar in both parts. If a move in the abstract is "long", then the one in the introduction is also "long" or at least "medium". And if one is short, the corresponding one is often short or even absent. 7 out of 11 articles follow this pattern. For example, in LV Segmentation and Motion Analysis from 4D Cardiac Images (Yun Zhu, 2010), move one of the abstract is "medium" whereas that of the introduction is "short"; move two of the abstract have only one sentence while that of the introduction has just a few; both move threes are long. Another example is A Model-based Self-adaptive Approach to Image Processing (Jim Nichols & Ted Bapty, 2004). This article lacks move one in both abstract and introduction, and move two and three are weighed relatively equal. Another point is if there is a short or no abstract, then the introduction is usually short, like in Spotlights in Biomedical Imaging (Andrew F. Laine, 2009), where there is no abstract and the introduction has only two sentences.
Concerning the purpose of the articles, there is not much characteristic revealed except that 4 out of 4 articles with purpose of developing an algorithm have long move three in abstracts. The fact is that 7 out of 11 abstracts has long move three but no obvious trend of introductions.
