在成人的体内CCT图像上看到的衰减增加的带，通常被指定为大脑皮层，已经在临床和实验上被证明是重建图像中的伪影。识别这种伪影可能有助于识别颅内病变，如浅硬膜下血肿。还研究了分离的皮质和白色物质的衰减值，并且不能解释高衰减带。
The band of increased attenuation seen on in vivo CCT images of adults, frequently designated as the cerebral cortex, has been proved clinically and experimentally to be an artifact in the reconstructed image. Recognition of this artifact may be of help in identifying intracranial lesions, such as shallow subdural hematomas. Attenuation values of isolated cortex and white matter were also studied and do not account for the band of high attenuation.
