Breath-Holding Instructions for X-Rays and CT Scans: What to Expect

X-Rays

Generally, breath-holding is not required for X-rays. Exceptions: chest or abdominal X-rays may require a brief breath-hold to reduce motion blur.

CT (Computed Tomography) Scans

You will be asked to hold your breath for a few seconds during the scan to prevent blurring from breathing motion. CT scanners rotate around you, taking multiple X-ray images; any movement degrades image quality.

• Breath-hold duration depends on body area and scan type.
• Chest/abdomen scans may require longer holds.
• Contrast dye may be used; breath-holding is especially important then.

Tips for Comfort

• Technicians will guide breathing technique.
• Inform your team if you have anxiety or breathing difficulties; they can adjust the protocol.
