The aim of this study was to evaluate the effectiveness of a new sealing method for preventing cross-contamination of photostimulable phosphor (PSP) plates.
Twelve new PSP plates were divided into 3 groups (PSP-a, PSP-b, and PSP- c) and placed in 3 different barriers (2 different brands of envelopes and a vacuum sealing method). All plates were exposed to X-rays with an aluminum step wedge, and the images were evaluated for the presence of any artifacts. After radiography, the PSP plates were removed from the barriers. The barriers and the PSP plates were disinfected and culture performed to assess any microorganism burden. Subsequently, the PSP plates were coated again with all barriers. The barriers were then contaminated and microbiologic specimens were collected. Subsequently, the barriers were wiped with alcohol. The PSP plates were removed, and microbiologic specimens were obtained.
No artifacts were recorded on the radiographic images on the sensors in any group. Microorganisms were detected on the PSP plates placed in envelopes. No colonization of microorganisms was detected on the vacuum sealed PSP plates.
The new vacuum-sealing method may be useful in preventing cross-contamination of PSP plates during radiographic procedures.
本研究旨在评估一种用于防止光激励荧光板（PSP板）交叉污染的新密封方法的有效性。
将12块新的PSP板分为3组（PSP-a、PSP-b和PSP-c），并放置在3种不同的屏障中（2种不同品牌的信封和一种真空密封方法）。所有板均用铝阶梯楔形物进行X射线照射，并对图像进行检查以确定是否存在任何伪影。放射摄影后，将PSP板从屏障中取出。对屏障和PSP板进行消毒并进行培养，以评估任何微生物负荷。随后，再次用所有屏障对PSP板进行覆盖。然后对屏障进行污染并收集微生物标本。随后，用酒精擦拭屏障。取出PSP板并获取微生物标本。
任何组的传感器上的放射图像均未记录到伪影。在置于信封中的PSP板上检测到微生物。在真空密封的PSP板上未检测到微生物定植。
新的真空密封方法可能有助于在放射摄影过程中防止PSP板的交叉污染。
