“…In addition, the images used in the comparisons were based on different size and weight neonates, and the location of the image receptor (directly behind neonate or in incubator tray) was not specified. 16 An interesting finding within this study was that technical difficulties were encountered with DDR, this was also seen in previous studies 8,17 whereby the limitations of DDR were noted especially in terms of the digital image receptor being too large to fit within the incubator tray.…”

“…The DR Samsung GM85 allows for CR imaging in situations such as when the S-Detector is not in use (broken/serviced) or depending on the size of the detector, some might not be suitable for incubator imaging. 8,16,17 Standard post processing was applied to the acquisitions and no manual adjustments were allowed.…”

“…10 There are many studies comparing CR and DDR in adult patients for various imaging examinations, [11][12][13][14][15] however only one study was found relating CR and DDR to neonatal imaging. 16 This study was a retrospective analysis only comparing image quality between CR and DDR. This study concluded that image quality for DDR was superior to CR; however, there was wide interrater variability and no radiation dose measures were provided.…”

Introduction: Neonates are a particularly vulnerable patient group with complex medical needs requiring frequent radiographic examinations. This study aims to compare computed radiography (CR) and direct digital radiography (DDR) portable imaging systems used to acquire chest x-rays for neonates within incubators.Method: An anthropomorphic neonatal chest phantom was imaged under controlled conditions using one portable machine but captured using both CR and DDR technology. Other variables explored were: image receptor position (direct and incubator tray), tube current and kV. All other parameters were kept consistent. Contrast-to-noise ratio (CNR) was measured using ImageJ software and dose-area-product (DAP) was recorded. Optimisation score was calculated by dividing CNR with the DAP for each image acquisition. Results:The images with the highest CNR were those acquired using DDR direct exposures and the images with lowest CNR were those acquired using CR with the image receptor placed within the incubator tray. This is also supported by the optimisation scores which demonstrated DDR direct produced the optimal combination with regards to CNR and radiation dose. The CNR had a mean increase of 50.3% when comparing DDR direct with CR direct respectively. This was also evident when comparing DDR and CR for in-tray acquisitions, with CNR increasing by a mean of 43.5%. A mean increase of 20.4% was seen in CNR when comparing DDR tray exposures to CR direct. Conclusion:DDR direct produced images of highest CNR, with incubator tray reducing CNR for both CR and DDR. However, DDR tray still had better image quality compared to CR direct.

“…Radiographic settings do not reflect changes in image detection technology, 1 and new imaging equipment is not by default optimized for its intended clinical use or particular patient group. 35 There has been a change from screen film systems to computed radiography (CR), and since CR is more tolerant of over-or under exposure than screen film systems, unnecessarily high radiation doses can occur with CR compared with screen film.…”

A literature review was conducted to determine norms for practice in neonatal intensive care units (NICU) around the world, given the harmful risks associated with radiation exposure at a very young age; risk of radiation-induced harm later in life increases with every X-ray image taken, more so for younger premature babies. Empirical studies including a measurement of radiation dose in a NICU, published after the year 2000 in a peer-reviewed journal, were collected. Measured doses to patients or X-ray phantoms, number of X-rays per stay and conclusions with recommendations made in response to these values were compared for 25 studies from around the world. The number of X-rays a patient underwent during a NICU stay ranged from 0 to 159. Younger, lower birth weight patients consistently had the greatest number of Xrays per stay. Recommended action based on measured dose ranged from extensive (to minimize risk to neonates) to minimal (to reduce risk) to none (because imaging benefits outweigh patient risk), with no consistent pattern linking recommended action with dose quantity. This demonstrates a broad range of interpretations of the As Low As Reasonably Achievable (ALARA) concept. These findings indicate a disparity in the response to neonatal X-ray dose concerns on a global scale, posing a public health risk to this particular neonatal population. More up-todate imaging protocols and dose limits specifically for the NICU environment with standardized dose monitoring would help minimize this risk to achieve the public health goals of prevention and harm reduction.
