2018年11月8日 · Both magnetic resonance imaging (MRI) and computed tomography (CT) are very sensitive to pathology of the skull base, but over the last two decades of innovation in imaging, it has become apparent that high-quality MRI is vital to both diagnosis and treatment planning in this neuroanatomic region.

2024年7月6日 · The base of the skull (or skull base) forms the floor of the cranial cavity and separates the brain from the structures of the neck and face. The skull base and vault collectively form the neurocranium. The base of the skull is a bony diaphragm composed of a number of bones - from anterior to posterior:

2015年12月29日 · The skull base can be evaluated by computed tomography (CT), which will demonstrate the bony structures of the skull base with its foramina and fissures for vessels and cranial nerves, the temporal bone, and sinonasal cavities. Magnetic resonance imaging (MRI) will demonstrate the contents of the foramina and fissures as well as the ...

CT and MRI are the imaging modality of choice for evaluation of skull base anatomy and pathology. This brief review article discusses common skull base pathologies along with the relevant anatomy and imaging techniques. The ASB forms the bottom of the anterior skull, separating the anterior cranial fossa from the paranasal sinuses and the orbits.

For virtually all complicated sinus or skull base lesions, both computed tomography (CT) and magnetic resonance imaging (MRI) are indicated. A noncontrast sinus or skull base CT, which covers the mastoids, temporal bone, and entire skull base, is recommended, and intravenous contrast is not usually necessary as the MRI will provide soft tissue ...

2019年7月24日 · Cross-sectional imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) enable detailed visualization of the intricate normal anatomy and disease spread at the skull base and play a central role in the diagnostic evaluation and surveillance of patients with skull base pathology.

Magnetic resonance (MR) imaging is a crucial tool for evaluation of the skull base, enabling characterization of complex anatomy by utilizing multiple image contrasts. Recent technical MR advances have greatly enhanced radiologists’ capability to diagnose skull base pathology and help direct management.

In the past two decades, numerous advancements and improvements in magnetic resonance imaging (MRI) have increased its ability to assess the skull base. These include the U.S. Food and Drug administration (FDA) approval of 3-T MRI scanners for clinical imaging and the development of unique coils and pulse sequences.

Computerized tomography (CT) and magnetic resonance imaging (MRI) have played complementary roles in the diagnosis of the various neoplastic and non-neoplastic lesions of the skull base. However, CT and conventional MRI may at times be insufficient to correctly pinpoint the accurate diagnosis.

The optimum imaging modality depends on the specific diagnostic question and area of interest; both CT and MR have complementary roles. This article focuses on the applied compartmental anatomy of the skull base and specific imaging protocols, and discusses the range of pathologies that neurologists will encounter.
