Traditional screening techniques, including barium enema and fecal occult blood tests, have been progressively replaced by more precise modalities, such as colonoscopy, liquid biopsy, and artificial intelligence (AI)-assisted imaging. Objective: This review explores the evolution of CRC diagnostic tools, from conventional imaging methods to cutting-edge AI-driven approaches, emphasizing their clinical utility, cost-effectiveness, and integration into multidisciplinary healthcare settings. Methods: A comprehensive literature search was conducted using the PubMed, Medline, and Scopus databases, selecting studies that evaluate various CRC diagnostic tools, including endoscopic advancements, liquid biopsy applications, and AI-assisted imaging techniques. Key inclusion criteria include studies on diagnostic accuracy, sensitivity, specificity, clinical outcomes, and economic feasibility. Results: AI-assisted colonoscopy has demonstrated superior adenoma detection rates (ADR), reduced interobserver variability, and enhanced real-time lesion classification, offering a cost-effective alternative to liquid biopsy, particularly in high-volume healthcare institutions. While liquid biopsy provides a non-invasive means of molecular profiling, it remains cost-intensive and requires frequent testing, making it more suitable for post-treatment surveillance and high-risk patient monitoring. Conclusions: The future of CRC diagnostics lies in a hybrid model, leveraging AI-assisted endoscopic precision with molecular insights from liquid biopsy. This integration is expected to revolutionize early detection, risk stratification, and personalized treatment approaches, ultimately improving patient outcomes and healthcare efficiency.<\/jats:p>","DOI":"10.3390\/diagnostics15080974","type":"journal-article","created":{"date-parts":[[2025,4,15]],"date-time":"2025-04-15T08:11:39Z","timestamp":1744704699000},"page":"974","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Advancing Colorectal Cancer Diagnostics from Barium Enema to AI-Assisted Colonoscopy"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-9600-6229","authenticated-orcid":false,"given":"Dumitru-Dragos","family":"Chitca","sequence":"first","affiliation":[{"name":"General Surgery Clinic, Colentina Clinical Hospital, 020125 Bucharest, Romania"},{"name":"General Surgery Clinic, Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1317-4937","authenticated-orcid":false,"given":"Valentin","family":"Popescu","sequence":"additional","affiliation":[{"name":"General Surgery Clinic, Colentina Clinical Hospital, 020125 Bucharest, Romania"},{"name":"General Surgery Clinic, Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anca","family":"Dumitrescu","sequence":"additional","affiliation":[{"name":"Family Medicine, Vitan Polyclinic, 031087 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian","family":"Botezatu","sequence":"additional","affiliation":[{"name":"General Surgery Clinic, Colentina Clinical Hospital, 020125 Bucharest, Romania"},{"name":"General Surgery Clinic, Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3179-7350","authenticated-orcid":false,"given":"Bogdan","family":"Mastalier","sequence":"additional","affiliation":[{"name":"General Surgery Clinic, Colentina Clinical Hospital, 020125 Bucharest, Romania"},{"name":"General Surgery Clinic, Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,11]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Safe, Then Sorry?\u2014The Psychological Biases that Drive Care Cascades","volume":"2025","author":"Daley","year":"2025","journal-title":"J.
