 Answer the question below. Please respond with the option letter (A, B, or C) first. (HINT: Each PubMedQA instance is composed of (1) a question which is either an existing research article title or derived from one, (2) a context which is the corresponding abstract without its conclusion, (3) a long answer, which is the conclusion of the abstract and, presumably, answers the research question, and (4) a yes/no/maybe answer which summarizes the conclusion.) 

Question:
Is diffusion-weighted imaging a significant indicator of the development of vascularization in hypovascular hepatocellular lesions? 

Options:
{'A': 'yes', 'B': 'no', 'C': 'maybe'}'

I need to determine if I should answer "yes," "no," or "maybe" based on the context, which resembles a PubMedQA question. The specific question is about whether diffusion-weighted imaging (DWI) indicates vascularization development in hypovascular hepatocellular lesions. Since I lack context, I might need to infer the answer from related studies. If the paper's title suggests a positive outcome for DWI, it likely supports a "yes" response. I should confirm this through a search.
