Hanging protocols in PACS are used to automate the arrangement of images on monitors per modality.

• A. True
• B. False
• C. Not used for modality
• D. Only used for archiving

Answer: (A)

Hanging protocols automate how images are displayed on the reading workstation for a given modality. They define the default layout, including which series appear, the order, the number of images per pane, and how they are arranged on the monitor, often with modality-specific window/level presets. This standardizes viewing so a radiologist sees the same, optimized presentation for chest X-rays, CT, MRI, and other modalities, which speeds interpretation and reduces display-related errors. They are about display and organization, not about archiving or storage, so options focusing on archiving or non-modality use don’t fit.
