To compare conventional and storage phosphor radiography of the injured cervical spine.
Sixty-five patients underwent imaging in a supine position while wearing a cervical collar. Matched storage phosphor and conventional lateral cervical spine radiographs were obtained with an 18 x 24-cm hybrid cassette. Edge-enhanced and nonenhanced copies of each computed radiograph were printed on film, and the images were sent via a computer network to a remote imaging workstation. Four radiologists read the conventional radiographs, the two hard-copy computed radiographs, and the soft-copy images and used a binary scale to score the visibility of bone and soft-tissue structures.
All readers scored better in all areas with computed radiographs, and a statistically significant (P = .030) improvement in performance was seen for soft-tissue structures.
Storage phosphor imaging offers advantages over conventional radiography, and digital images may be a viable alternative to film.
比较受伤颈椎的传统X线摄影和存储磷光体X线摄影。
65例患者戴着颈托仰卧位进行成像。使用18×24厘米的混合暗盒获取匹配的存储磷光体和传统颈椎侧位X线片。将每张计算机X线片的边缘增强和未增强副本打印在胶片上,并通过计算机网络将图像发送到远程成像工作站。四位放射科医生阅读传统X线片、两张硬拷贝计算机X线片和软拷贝图像,并使用二元量表对骨骼和软组织结构的可见性进行评分。
所有读者对计算机X线片所有区域的评分都更高,并且软组织结构的性能有统计学意义的改善(P = 0.030)。
存储磷光体成像比传统X线摄影具有优势,数字图像可能是胶片的可行替代方案。
