Sample item

Why should radiology reports compare current images with prior studies when available?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Interval change can distinguish stable findings from active progression

Comparison with prior imaging can reveal growth, resolution, or long-term stability, which often changes the differential diagnosis and urgency of follow-up.

Option by option

  • A. Interval change can distinguish stable findings from active progression (correct)

    Correct: temporal change provides important diagnostic context.

  • B. Comparison eliminates all diagnostic uncertainty

    Imaging comparison reduces but cannot eliminate uncertainty.

  • C. Prior images always make clinical history unnecessary

    Clinical history remains important alongside image comparison.

  • D. Stable findings never require clinical correlation

    Stable findings may still need correlation in the right context.
