What’s The Most Comprehensive Medical Dataset You’ve Used That Includes EHRs, Physician Dictation, And Imaging (CT, MRI, X-ray)? How Well Did It Cover Diverse Patient Demographics And Geographic Regions?

I’m exploring truly multimodal medical datasets that combine all three elements:

• Structured EHR data
• Physician dictation (audio or transcripts)
• Medical imaging (CT, MRI, X-ray)

Looking for real-world experience—especially around:

• Whether the dataset was diverse in terms of age, gender, ethnicity, and geographic representation
• If modality coverage felt balanced or skewed toward one type
• Practical strengths or limitations you encountered in using such datasets

Any specific dataset names, project insights, or lessons learned would be hugely appreciated!
