However, challenges remain in generating clinically accurate and detailed reports and in evaluating them effectively. Our work investigates the role of prompt engineering in improving both the generation and evaluation of medical reports. We make three main contributions. First, we analyze the effect of various prompting strategies on the performance of different VLMs, including GPT-4o mini, LLaMA 11B, and LLaVA-Med. We introduce a structured prompt design based on clinically relevant anatomical checkpoints that significantly improve reports coherence and clinical fidelity. Second, we propose a novel LLM evaluation strategy that uses checkpoints to anchor the assessment of generated reports, providing an interpretable and clinically meaningful metric. Third, we explore two integrated frameworks that combine generation and evaluation, enabling iterative improvement through example-based and self-supervised prompt optimization. Experimental results on the CT-RATE dataset demonstrate that prompt engineering can substantially increase both the quality and the evaluability of medical reports.
