NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Artificial Intelligence Technologies for Detection and Quantification of Hepatic Steatosis: A Scoping Review
ABSTRACT
Background:
Non-alcoholic fatty liver disease linked to an increased risk of morbidity and mortality in afflicted individuals. Non-invasive liver imaging technologies such ultrasound (US) is the preferable method for screening hepatic steatosis because to its non-invasiveness, cheap cost, and widespread availability. Artificial intelligence (AI), in particular deep learning algorithms, has garnered widespread notice for its superior performance on image identification and quantification. They are capable of quantitatively assessing complicated medical image properties automatically and achieving better diagnostic accuracy while increasing efficiency. AI is frequently utilized and gaining popularity in the field of liver medical imaging, which includes radiology, nuclear medicine and ultrasound. AI can assist physicians in making more accurate and reproducible imaging diagnoses while also reducing the workload of physicians.
Objective:
The primary purpose of this work was to conduct a scoping review of artificial intelligence technologies for hepatic steatosis detection and quantification. It also aimed to explore the role of AI technologies on Ultrasonography for the detection and quantification of hepatic steatosis.
Methods:
The researcher searched several electronic bibliographies including Google Scholar, PubMed, EMBASE, CINAHL, PsychINFO, ACM Digital, IEEEXplore, and Scopus. The references retrieved were investigated for additional relevant studies through the backward and forward reference list checking strategy. One reviewer carried out the studies selection and data extraction.
Results:
A total of 718 publications were retrieved; 268 duplicates were removed. After scanning the titles and abstracts, 234 were excluded. After scanning the full texts, many articles were excluded for the following reasons: studies focusing on diseases other than liver parenchymal diseases (n = 39), studies that did not confirm the specified outcomes or confirmation study population (n = 58), studies that were not original research, i.e., reviews, editorials (n = 106), and studies not written in English (n = 8). The qualitative analysis comprised a total of 25 publications.
Conclusions:
This review illustrates the potential for AI systems to aid in the diagnosis and stage of liver fibrosis and non-alcoholic fatty liver disease. By incorporating AI into established noninvasive methods, effective diagnostic tools with an ideal mix of sensitivity and specificity are created. Before adopting these AI-assisted systems in clinical practice, it is necessary to validate these models in additional independent cohorts.
