Accurate preoperative diagnosis of petrous apex lesions is critical because the surgical approaches used for this region are different depending upon the specific disease process involved. While CT and MRI have each improved the accuracy of preoperative diagnosis of petrous apex pathology, these imaging studies are most helpful when used in conjunction with one another. When systematically applied, the combination of CT with contrast and MRI (with and without gadolinium) permits accurate differential diagnosis of primary petrous apex lesions. This review presents the imaging approach employed at the House Ear Clinic for the differential diagnosis of primary lesions of the petrous apex.
准确的岩尖病变术前诊断至关重要，因为针对该区域所采用的手术入路会因具体涉及的疾病进程而有所不同。虽然CT和MRI各自提高了岩尖病变术前诊断的准确性，但这些影像学检查相互结合使用时最有帮助。当系统应用时，CT增强扫描与MRI（使用和不使用钆对比剂）相结合能够对原发性岩尖病变进行准确的鉴别诊断。本综述介绍了豪斯耳科诊所用于原发性岩尖病变鉴别诊断的影像学方法。
