Cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH) is a delayed, reversible narrowing of the intracranial vasculature that occurs most commonly 4 to 14 days after aneurysmal SAH and can lead…
This article briefly discusses the clinical features, natural history, and epidemiology of intracranial cerebral aneurysms, along with current diagnostic imaging techniques for their detection. The main focus is on the…
Peripheral nerve surgery represents a broad field of pathologic conditions, medical specialties, and anatomic regions of the body. Anatomic understanding of hierarchical nerve structure and the peripheral nervous system aids…
Magnetic resonance (MR) neurography has progressed in the past 2 decades because of rapid technological developments in both hardware and software. In addition to improvements in high-resolution anatomic pulse sequences,…
Magnetic resonance (MR) imaging of the nerves, commonly known as MR neurography is increasingly being used as noninvasive means of diagnosing peripheral nerve disease. High-resolution imaging protocols aimed at imaging…
Magnetic resonance (MR) neurography – guided nerve blocks and injections describe a techniques for selective percutaneous drug delivery, in which limited MR neurography and interventional MR imaging are used jointly…
This article is a primer on the pathophysiology and clinical evaluation of peripheral neuropathy for the radiologist. Magnetic resonance neurography has utility in the diagnosis of many focal peripheral nerve…
Peripheral nerve enlargement may be seen in multiple conditions including hereditary or inflammatory neuropathies, sporadic or syndromic peripheral nerve sheath tumors, perineurioma, posttraumatic neuroma, and intraneural ganglion. Malignancies such as…
Imaging evaluation of cranial neuropathies requires thorough knowledge of the anatomic, physiologic, and pathologic features of the cranial nerves, as well as detailed clinical information, which is necessary for tailoring…
The most common sites of nerve entrapment are in the upper extremity, commonly diagnosed based on clinical findings and electrophysiologic studies. Cross-sectional imaging modalities, such as ultrasonography and magnetic resonance…
