Learning objectives
To discuss basic concepts of medical statistics focusing on those related to diagnostic accuracy studies
To review the types of scientific studies and publications related to the field of diagnostic imaging
Background
The first step of radiology success is to produce technically adequate images. After that, imaging studies must be accurate and provide information that has the potential to change the medical care, and ultimately the patient’s health, and that is what is called, levels of diagnostic efficacy (Fig. 2). [1]
Knowledge of basic research methodology is essential for academic radiologists. However, for non-academic radiologists, it is still crucial to understand these basic concepts and learn how to read and appraise the medical literatures.

Hypothesis testing
A hypothesis is a statement or assumption about the studied population that can be tested to prove whether it is true or not. Research projects usually begin with a question that must be formulated into a testable hypothesis. This lead to choose of the study designs and statistical tests that can be used to prove or disprove the hypothesis. Simply speaking, if we are considering a new imaging test and want to compare it to an existing old test, we assume that there...
Conclusion
Adequate knowledge of medical statistics and research allows radiologists to improve their research as well as clinical skills.
