During pluridirectional tomography dense bone creates ghost shadows that simulate chronic disease and soft-tissue masses within the middle ear cavity. This effect was demonstrated in three dried skulls. Cholesteatomas were simulated in three more temporal bones with a mixture of 2% iodine in paraffin. Three different high-resolution computed tomographic scanners clearly demonstrated middle ear anatomy and the simulated soft-tissue masses in the skulls.
在多向断层摄影中，致密骨会产生假影，模拟中耳腔内的慢性疾病和软组织肿块。这种效应在三个干燥的头骨中得到了证实。在另外三个颞骨中用2%碘与石蜡的混合物模拟胆脂瘤。三种不同的高分辨率计算机断层扫描仪清楚地显示了头骨中的中耳解剖结构和模拟的软组织肿块。
