Gd-DTPA-enhanced MRI provided accurate demonstration of the site and extension of a haemangioma of the petrous bone. Enhanced-MRI could allow early detection and differentiation from the other more common tumours of the geniculate ganglion area, thereby permitting the surgeon to remove the tumour, while preserving the facial nerve. CT is, however, required to display the characteristic ossification in these tumours.
钆喷酸葡胺增强磁共振成像（Gd-DTPA-enhanced MRI）能准确显示岩骨血管瘤的部位及范围。增强磁共振成像可实现早期检测，并与膝状神经节区域其他更常见的肿瘤进行鉴别，从而使外科医生在保留面神经的同时切除肿瘤。然而，这些肿瘤中的特征性骨化需要计算机断层扫描（CT）来显示。
