  2. Vertebral artery - Wikipedia

    en.wikipedia.org/wiki/Vertebral_artery

    The vertebral arteries are major arteries of the neck. Typically, the vertebral arteries originate from the subclavian arteries. Each vessel courses superiorly along each side of the neck, merging within the skull to form the single, midline basilar artery. As the supplying component of the vertebrobasilar vascular system, the vertebral ...

  3. Artery of Adamkiewicz - Wikipedia

    en.wikipedia.org/wiki/Artery_of_Adamkiewicz

    In human anatomy, the artery of Adamkiewicz (also arteria radicularis magna) is the largest anterior segmental medullary artery and the dominant segmental feeding vessel to the thoracic cord, supplying the anterior aspect of the cord via the anterior spinal artery. [3] It is a radiculomedullary artery arising from the spinal dorsal branch of ...

  4. Vertebrobasilar insufficiency - Wikipedia

    en.wikipedia.org/wiki/Vertebrobasilar_insufficiency

    Neurology. Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow (ischemia) in the posterior circulation of the brain. The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex. [1]

  5. Cerebral angiography - Wikipedia

    en.wikipedia.org/wiki/Cerebral_angiography

    Cerebral angiography is a form of angiography which provides images of blood vessels in and around the brain, thereby allowing detection of abnormalities such as arteriovenous malformations and aneurysms. [1] It was pioneered in 1927 by the Portuguese neurologist Egas Moniz at the University of Lisbon, who also helped develop thorotrast for use ...

  6. Anterior spinal artery - Wikipedia

    en.wikipedia.org/wiki/Anterior_spinal_artery

    LFB-HE stain. In human anatomy, the anterior spinal artery is the artery that supplies the anterior portion of the spinal cord. It arises from branches of the vertebral arteries and courses along the anterior aspect of the spinal cord. It is reinforced by several contributory arteries, especially the artery of Adamkiewicz.

  7. MRI pulse sequence - Wikipedia

    en.wikipedia.org/wiki/MRI_pulse_sequence

    An MRI pulse sequence in magnetic resonance imaging (MRI) is a particular setting of pulse sequences and pulsed field gradients, resulting in a particular image appearance. [ 1 ] A multiparametric MRI is a combination of two or more sequences, and/or including other specialized MRI configurations such as spectroscopy .

  8. Meningeal branches of vertebral artery - Wikipedia

    en.wikipedia.org/wiki/Meningeal_branches_of...

    The meningeal branches of vertebral artery (posterior meningeal branch) springs from the vertebral opposite the foramen magnum, ramifies between the bone and dura mater in the cerebellar fossa, and supplies the falx cerebelli. [1][2][3] It is frequently represented by one or two small branches.

  9. Vertebral artery dissection - Wikipedia

    en.wikipedia.org/wiki/Vertebral_artery_dissection

    Aspirin, heparin, warfarin. Frequency. 1.1 per 100,000. Vertebral artery dissection (VAD) is a flap-like tear of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow.
