From this book "Deep Learning and Convolutional Neural Networks for Medical Image Computing"

Abstract Computerized algorithms and solutions in processing and diagnosis mammography X-ray, cardiovascular CT/MRI scans, and microscopy image play an important role in disease detection and computer-aided decision-making. Machine learning techniques have powered many aspects in medical investigations and clini- cal practice. Recently, deep learning is emerging a leading machine learning tool in computer vision and begins attracting considerable attentions in medical imaging. In this chapter, we provide a snapshot of this fast growing field specifically for mammography, cardiovascular, and microscopy image analysis.

this is beginning of the chapter 2 of that book, to give the outline of this chapter, which expression is better

expression_1:

In this chapter, we provide a snapshot of this fast growing field specifically for mammography

expression_2

In this chapter, we'll provide a snapshot of this fast growing field specifically for mammography
