KUALA LUMPUR, October 22 2026, A radiation protection system developed by Egg Medical has been found to significantly reduce radiation exposure among cardiac catheterisation laboratory staff, potentially allowing them to work without heavy lead aprons, according to a study published in the Journal of the American Heart Association.
The study, conducted at The Christ Hospital in Cincinnati, Ohio, evaluated the company’s EggNest enhanced radiation protection devices (ERPDs).
Study principal investigator and The Christ Hospital interventional cardiologist Dr Santiago Garcia said the system was designed to protect the entire medical team, giving staff the option of working without aprons or wearing lightweight alternatives.
The study found that the estimated annual radiation dose at the collar of primary operators dropped from 86.7 millirem (mRem) under standard shielding to 25.5 mRem when the EggNest Complete system was used.
When combined with ultralight 0.125-millimetre aprons, the annual dose for primary operators fell further to 1.4 mRem, compared with 51.4 mRem when traditional 0.5-millimetre lead aprons were used with standard shielding.
Egg Medical said the total annual radiation exposure among laboratory staff using EggNest Complete — including primary operators, scrub assistants and circulating nurses — was equivalent to one per cent of the 5,000 mRem annual maximum set by the International Commission on Radiological Protection.
The company also cited the United States Centers for Disease Control and Prevention, which estimates that a five- to six-hour flight exposes passengers to about 3.5 mRem of radiation.
Separately, Egg Medical said the Texas Department of State Health Services had recently granted a state radiation variance to Methodist Healthcare System of San Antonio.
