Abstract:In medicine, particularly in radiology, there are great expectations in artificial intelligence (AI), which can “see” more than human radiologists in regard to, for example, tumor size, shape, morphology, texture and kinetics — thus enabling better care by earlier detection or more precise reports. Another point is that AI can handle large data sets in high-dimensional spaces. But it should not be forgotten that AI is only as good as the training samples available, which should ideally be numerous enough to co… Show more
“…Furthermore, it also requires human oversight and a more complete explanation. Interactive machine learning with the ”human in the loop” could be a potential solution to this limitation of AI [42] , [43] . It should be noted that physicians/radiologists have conceptual understanding and experience that no AI can fully learn.…”

“…Additionally, in several reports, radiologists have expressed that they do not believe AI will replace them in the foreseeable future [ 14 , 18 , 19 ]. The model usually proposed is a cooperation of AI and radiologists, with AI facilitating and increasing the efficiency of radiologists and improving the diagnostic and prognostic workflows [ 20 ]. A radiologist might not need to know the technical details of ML/DL algorithms; however, knowing some general concepts would help one prepare for an even-more technology-rich practice.…”
Machine-learning (ML) and deep-learning (DL) algorithms are part of a group of modeling algorithms that grasp the hidden patterns in data based on a training process, enabling them to extract complex information from the input data. In the past decade, these algorithms have been increasingly used for image processing, specifically in the medical domain. Cardiothoracic imaging is one of the early adopters of ML/DL research, and the COVID-19 pandemic resulted in more research focus on the feasibility and applications of ML/DL in cardiothoracic imaging. In this scoping review, we systematically searched available peer-reviewed medical literature on cardiothoracic imaging and quantitatively extracted key data elements in order to get a big picture of how ML/DL have been used in the rapidly evolving cardiothoracic imaging field. During this report, we provide insights on different applications of ML/DL and some nuances pertaining to this specific field of research. Finally, we provide general suggestions on how researchers can make their research more than just a proof-of-concept and move toward clinical adoption.
“…The labeled data require radiologists to label, and its quality depends on the labeling of radiologist as such. 9 Other datasets, including validation and test sets, are fed again to validate after finishing the learning process. External validation by independent cohort and from real-life data from several institutions is advised.…”

“…This type of variability makes an unnecessary complexity for the computer to normalize data. 9 Unsupervised learning learns the dataset on the basis of data patterns without using ground truth and as in the developmental process. 13 Hybrid learning that uses partially labeled data and unlabeled data is the other future option.…”
Artificial intelligence (AI) in radiology is recently a rapidly growing subject. Much literature about AI in radiology has been launched within 5 years, as well as commercial AI companies. This phenomenon makes some old radiologists feel worried about losing their jobs, and junior doctors hesitate to choose radiology as a specialty. Currently, implementations of proprietary AIs in clinical practice are limited, with a default setting for a convenient human overwrite. The AIs in clinical imaging largely remain either investigational as part of clinical/pre-clinical trials or being developed for commercialized purposes. Radiologists have an important role in all AI processes from the beginning to the end and vital in training the machine, as well as to validate its added benefit for outcome prediction/prognostication. This article will discuss the importance for radiologists to develop, implement, and monitor AI in clinical imaging, together with some ethical considerations. We would like to encourage radiologists to use AI as an adjunct tool, to save time and have better performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
