The application of wide aperture scanners to neuroradiology permits improved anatomic definition and localization of intracranial and intraorbital lesions. Coronal scans are most useful in demonstrating lesions of the skull base and apex, distinguishing between infra- and supratentorial lesions, and in determining if a lesion is intra- or extraaxial. Limitations of coronal scans include discomfort in positioning, high spatial frequency artifacts, and additional radiation exposure.
宽孔径扫描仪在神经放射学中的应用可改善颅内和眶内病变的解剖清晰度及定位。冠状位扫描在显示颅底和颅尖病变、区分幕下和幕上病变以及确定病变是轴内还是轴外病变方面最为有用。冠状位扫描的局限性包括定位时的不适、高空间频率伪影以及额外的辐射暴露。
