When reviewing medical records to explore factors related to MRI scans, what is true about the physician's study?

The assertion that the study is human subject research eligible for expedited review holds true because when medical records are reviewed to investigate factors related to MRI scans, this typically qualifies as research involving human subjects. In such contexts, researchers often utilize existing records, which can involve private health information. If the study poses minimal risk to the participants and involves methods that are already established in clinical practice, it may be eligible for expedited review by an Institutional Review Board (IRB). This allows for a more efficient process while ensuring that the ethical standards of research are maintained.

In general, expedited reviews are designed for studies that do not necessitate a full board review due to their lower risk nature, provided they meet specific criteria set by regulatory bodies. Therefore, in this case, the nature of the study related to analyzing MRI scan factors through existing medical records aligns well with the conditions for expedited IRB consideration.
