Diagnostic Imaging and Mechanical Objectivity in Medicine.

Area of Science:

• Medical history
• Scientific illustration
• Medical imaging technology

Background:

• Early scientific atlases relied on artistic depictions, introducing subjectivity into objective medical analysis.
• Confrontations over accuracy in the 19th century led to the concept of mechanical objectivity.
• This concept revolutionized scientific knowledge and medical practices.

Purpose of the Study:

• Trace the evolution of mechanical objectivity in medical imaging from the 19th century to present-day innovations.
• Examine the impact of technologies like X-ray, digitization, and artificial intelligence on objectivity.
• Identify challenges in mitigating human bias in medical imaging practices.

Main Methods:

• A narrative literature review was performed.
• Scopus® database was utilized for literature search.
• Guidance from medical historians and practicing physicians ensured historical accuracy and clinical relevance.

Main Results:

• Despite a century-long pursuit of mechanical objectivity in diagnostic imaging, human bias remains a significant factor.
• Advancements in medical imaging technologies have not fully eliminated subjectivity.
• The historical review details the development of imaging technologies and the role of bias.

Conclusions:

• The quest for mechanical objectivity in medical imaging has spanned over a century.
• Human bias continues to be a critical challenge in interpreting medical images accurately and efficiently.
• The field of medical imaging, including artificial intelligence, must address human bias for improved diagnostic outcomes.
