Question

How will you, as a technologist, overcome age variations, trauma, and other factors that increase the likelihood of motion on your radiographic image?

Answer 1

Following methods can be used:-

1. Patient should be comfortable on bed if not I can use Stabilization Measures like foam pads, taping, snug wrapping with sheets, or even bite bars may be useful.

Infants can be swaddled or their head can be fixed.

2 Using surface coils confined to the area of interest will minimize unwanted signals from moving tissues located farther away.

3. Sedation or general anesthesia may be required.

4.Increasing number of signals averaged (NSA, NEX) will reduce artifacts.

5. Single-slice ultrafast sequences (HASTE, EPI, TrueFISP) may acquire images rapidly enough (2-5 sec) to freeze bulk motion.

6. Navigator echo techniques (e.g., PACE) use additional RF-pulses to track cardiac or diaphragmatic position.
