Hand Signals Developed for Communication During CT

Series of hand signals developed for communication between radiologists, radiographers

MONDAY, April 25, 2016 (HealthDay News) — A series of hand signals has been developed for use during computed tomography (CT) or angiographic procedures, according to an article published online April 20 in the Journal of Medical Radiation Sciences.

Noting that when performing CT-guided or angiographic procedures, radiologists need to communicate with radiographers at a workstation behind radiation-shielding glass, Edward H. Wang, M.B.B.S., from the Royal Adelaide Hospital in Australia, and colleagues developed a set of standardized hand signals to aid communication.

The hand signals developed by the researchers include signals for OK; code blue/emergency; distance, for measuring the distance to the target lesion; magnification, for magnifying the image displayed on the CT monitor; altering the window width, and voltage and current during an angiographic procedure; and table in and out for moving the table.

“These signals are useful and easy to learn,” the authors write. “They can be adopted or modified by other institutions to help improve inter-professional communication, leading to better patient care.”
