Computer Tomographic Findings of Brain Tumors Projected on X-Rays and Scalp
Using computed tomography, it is possible in almost every case to directly establish the diagnosis of tumors, including their size and their relation to neighboring structures. CT scans have become more and more precise, enabling neuroradiologists to detect even very small tumors. This sometimes makes it difficult for the neurosurgeon to find the tumor at surgery. Only after section scans, which up to now have usually been horizontal, are transferred exactly onto X-rays and then onto the scalp can trepanation be so centred as to afford aid in localizing the tumor. A typical example is the parasagittal tumor, in which case major errors can occur if the plane of the layer is unknown.
