AI contribution statement: ChatGPT (OpenAI) was used only in a limited supportive manner. In the manuscript text, its use was restricted to minor linguistic and stylistic refinement during revision. For the two schematic figures, ChatGPT was used only to assist visual drafting and graphic arrangement, including the organization of boxes, arrows, icons, and overall layout. The scientific concepts, wording, figure logic, and final content were entirely defined, reviewed, and approved by the authors. No AI tool was used to generate data, analyze results, interpret findings, or make scientific decisions.
Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article.

Core Tip

Core Tip: Habitat imaging offers a different way of reading magnetic resonance imaging in hepatocellular carcinoma, moving beyond simple lesion description and trying to capture the tumor’s internal spatial heterogeneity. Its value lies not only in the possibility of predicting response after transarterial chemoembolization, but also in helping clinicians think more carefully about pretreatment selection and multidisciplinary treatment planning. At present, however, this approach is still constrained by important limitations, including methodological fragility, poor standardization, and the lack of solid prospective validation. The key issue is no longer whether habitat imaging is conceptually attractive, but whether it is robust enough to become genuinely useful in clinical practice.
