Over the past two decades, computer-aided detection or diagnosis has
emerged as a highly promising field of research. Its primary goal is to
enhance the diagnostic and treatment procedures for radiologists and
clinicians in medical image analysis. With the help of big data and
advanced Artificial Intelligence (AI) technologies, i.e., machine
learning and deep learning algorithms, assist in making our healthcare
system more convenient, active, efficient, and personalized. The primary
goal of the literature survey study is to present a thorough overview of
the most important developments related to Computer-Aided Diagnosis
(CAD) systems in medical imaging. This survey holds considerable
importance for researchers and professionals in both medical and
computer science. Several reviews regarding specific facets of CAD in
medical imaging already exist. Nevertheless, the main emphasis of this
paper is on covering the complete range of CAD systems’ capabilities in
medical imaging. This review article introduces the background concept
used for typical CAD systems in medical imaging by outlining and
comparing several methods frequently employed in recent studies. The
article also offers a comprehensive and well-structured survey of CAD in
medicine, drawing from a meticulous selection of relevant publications.
Moreover, it describes the process of handling medical images and
introduces state-of-the-art AI-based CAD technologies in medical
imaging, along with the future directions of CAD. This study indicates
that deep learning algorithms are the most effective way to diagnose or
detect diseases.
