Research in departments of diagnostic radiology: a question of method limitation.

Research support, training, and methods in diagnostic radiology have been the focus of analysis for 2 decades and continue to be important in the effective competition for research grants, especially those granted by the National Institutes of Health. The limitation of hypothesis formation and testing to imaging methods alone, however, could be a major impediment to more successful sponsorship of research in this discipline. The author emphasizes that a well-designed research plan in diagnostic radiology should not be restricted solely to imaging methods and should include such factors as the formation of well-defined hypotheses testable by means of inductive reasoning and, most important, flexibility in approaches to research methods. Other factors influencing effective research in diagnostic imaging include the establishment of mentors for continuous training and support, uninterrupted time for research, and a totally supportive environment. Improvements in these areas may enhance the competitiveness of research proposals from departments of diagnostic radiology.
