Advanced Imaging in the Evaluation of Migraine Headaches.

Neuroimaging Clin N Am 2019 May 19;29(2):301-324. Epub 2019 Feb 19.

Department of Radiological Sciences, David Geffen School of Medicine, University of California Los Angeles, 924 Westwood Boulevard, Suite 615, Los Angeles, CA 90024, USA.

The use of advanced imaging in routine diagnostic practice appears to provide only limited value in patients with migraine who have not experienced recent changes in headache characteristics or symptoms. However, advanced imaging may have potential for studying the biological manifestations and pathophysiology of migraine headaches. Migraine with aura appears to have characteristic spatiotemporal changes in structural anatomy, function, hemodynamics, metabolism, and biochemistry, whereas migraine without aura produces more subtle and complex changes.

The Connection Between Patent Foramen Ovale and Migraine.

Neuroimaging Clin N Am 2019 May;29(2):261-270

Cardiology, University of California, Los Angeles, Room B-976 Factor Building, Box # 951717, Los Angeles, CA 90095-1717, USA. Electronic address:

"Observational studies have identified a relationship between patent foramen ovale (PFO) and migraine headache. In people who have migraine with aura, 40% to 60% have a PFO, compared with 20% to 30% in the general adult population. It is hypothesized that migraine, especially migraine with aura, may be triggered by hypoxemia or vasoactive chemicals (eg, serotonin), which are ordinarily metabolized during passage through the lungs.

Imaging of Ménière Disease.

Neuroimaging Clin N Am 2019 Feb;29(1):19-28

Department of Radiology, GZA Hospitals Antwerp, Oosterveldlaan 24, Wilrijk 2610, Belgium.

Visualization of the morphologic substrate of Ménière disease, the endolymphatic hydrops, can be performed using noncontrast or contrast-enhanced MR imaging techniques. Noncontrast MR imaging uses a heavily T2-weighted sequence; however, its reproducibility remains to be confirmed. Contrast-enhanced MR imaging techniques mainly use a 3-dimensional fluid-attenuated inversion recovery sequence after intratympanic gadolinium administration or after a 4-hour delayed intravenous gadolinium administration.

Neuro-Interventional Management of Acute Ischemic Stroke.

Neuroimaging Clin N Am 2018 Nov;28(4):625-638

Interventional Neuroradiology and Neuroradiology, Department of Radiology, Huntington Memorial Hospital, 100 West California Boulevard, Pasadena, CA 91105, USA.

Restoration of cerebral blood flow is the most important step in preventing irreversible damage to hypoperfused brain cells after ischemic stroke from large-vessel occlusion. For those patients who do not respond to (or are not eligible for) intravenous thrombolysis, endovascular therapy has become standard of care. A shift is currently taking place from rigid time windows for intervention (time is brain) to physiology-driven paradigms that rely heavily on neuroimaging. Read More

Clot Pathophysiology: Why Is It Clinically Important?

Neuroimaging Clin N Am 2018 Nov 15;28(4):611-623. Epub 2018 Sep 15.

Laboratory for Thrombosis Research, KU Leuven Campus Kulak Kortrijk, E. Sabbelaan 53, 8500 Kortrijk, Belgium.

Cerebral ischemic stroke treatment may change significantly now that clots are actually physically removed from the patient using thrombectomy. This allows for an analysis of the content of the clots as well as the correlation of the imaging findings and the clot behavior and morphology. This article illustrates how the interaction of different clots varies in the clinical setting and how analysis of clot composition, as well as the search for new pharmacologic targets, can lead to a better understanding of the pathophysiology and therapy resistance, in turn providing possibilities for a better approach in the treatment.

Oligemia, Penumbra, Infarction: Understanding Hypoperfusion with Neuroimaging.

Neuroimaging Clin N Am 2018 Nov;28(4):599-609

Department of Radiology, University of Washington, 1959 Northeast Pacific Street, Room NW011, Seattle, WA 98195, USA. Electronic address:

Despite recent progress in the treatment of acute ischemic stroke with multiple trials demonstrating improved clinical outcome associated with endovascular thrombectomy up to 24 hours after onset, there is potential opportunity for optimal patient selection and treatment algorithm to further improve treatment outcome. Current limitation is in part caused by inconsistency of imaging protocols and imaging-based definitions of oligemia, penumbra, and infarction core within the various hypoperfusion states. To truly maximize the impact of imaging in acute ischemic stroke, imaging definitions of hypoperfusion states need to be more consistent and validated to correctly reflect different severities of ischemic injury.

Advanced Neuroimaging of Acute Ischemic Stroke: Penumbra and Collateral Assessment.

Neuroimaging Clin N Am 2018 Nov 15;28(4):585-597. Epub 2018 Sep 15.

Department of Radiology, Division of Neuroimaging and Neurointervention, Stanford Healthcare, 300 Pasteur Drive, Stanford, CA 94305, USA.

Acute ischemic stroke (AIS) occurs when there is a sudden loss in cerebral blood flow due to embolic or thromboembolic occlusion of a cerebral or cervical artery. Patients with AIS require emergent neuroimaging to guide treatment, which includes intravenous thrombolysis and endovascular mechanical thrombectomy (EMT). Recent advances in AIS treatment by EMT has been driven in part by advances in computed tomography (CT) and MR imaging neuroimaging evaluation of ischemic penumbra and pial collateral vessels.

Authors:
Nina J Solenski

Neuroimaging Clin N Am 2018 Nov;28(4):551-563

Department of Neurology, University of Virginia School of Medicine, University of Virginia Health System, PO Box 800394, Hospital Drive, Charlottesville, VA 22908, USA. Electronic address:

Teleradiology, transfer of radiology images to a distant diagnostician, has existed for more than 50 years and is a fundamental element in telestroke programs. Teleradiology allows access to expertise for accurate and rapid interpretation of noncontrast CT (NCCT) scans to distinguish ischemic stroke from hemorrhagic stroke. No acute stroke thrombolytic or clot retrieval treatment decision can be made without it. Read More

Clinical Distinction of Cerebral Ischemia and Triaging of Patients in the Emergency Department: Mimics, Wake-ups, Late Strokes, and Chameleons.

Neuroimaging Clin N Am 2018 Nov;28(4):537-549

Department of Neurology, Loyola University Chicago, Stritch School of Medicine, Loyola University Medical Center, 2160 South First Avenue, Building 105, Room 2700, Maywood, IL 60153, USA.

Non-stroke conditions may present in ways suggestive of ischemic stroke (ie, stroke mimic). Alternatively, the clinical presentation of ischemic stroke can vary considerably and may appear similar to another condition (ie, stroke chameleon). Common and uncommon mimics and chameleons are presented with discussion of key considerations to improve diagnostic accuracy. Read More

Radiation Dose Considerations in Emergent Neuroimaging.

Neuroimaging Clin N Am 2018 Aug;28(3):525-536

Department of Radiology, Brigham and Women's Hospital, Harvard Medical School, 75 Francis Street, Boston, MA 02115, USA. Electronic address:

Computed tomography is often the first-line diagnostic imaging modality in the evaluation of patients with neurologic emergencies. A patient-centered approach to radiation dose management in emergent neuroimaging thus revolves around the appropriate use of computed tomography, including clinical decision support for ordering providers, thoughtful protocol design, the use of available technological advances in computed tomography, and radiation exposure monitoring at a population level. A multifaceted approach can help to minimize radiation exposure to individual patients while preserving diagnostic quality imaging. Read More

Current Challenges in the Use of Computed Tomography and MR Imaging in Suspected Cervical Spine Trauma.

Neuroimaging Clin N Am 2018 Aug 8;28(3):483-493. Epub 2018 Jun 8.

Department of Radiology and Biomedical Imaging, Yale University School of Medicine, 333 Cedar Street, New Haven, CT 06510, USA.

There is controversy regarding the optimal imaging strategy in adult blunt trauma patients for suspected cervical spine trauma. Some investigators recommend negative computed tomography (CT) alone to clear the cervical spine in adult blunt trauma patients, while others insist that MR imaging is necessary, especially among obtunded adult blunt trauma patients. CT is an excellent imaging modality for bony cervical spine injury; however, there is a nonzero rate of clinically significant cervical spine injuries missed on CT. Read More
