Variations in Arterial Anatomy
Variations in Arterial Anatomy Introduction MDCTA offers a new appreciation of arterial and venous anatomy. All arteries and veins will show complete ‘filling’ or enhancement which, if the protocol is…
Intracranial Imaging in Stroke: Ischaemic
Intracranial Imaging in Stroke: Ischaemic Introduction ‘Stroke’ is a clinical diagnosis characterized by a sudden onset of acute neurological symptoms of presumed vascular origin. This chapter illustrates some of the…
Visual Failure
Visual Failure Introduction A patient with visual failure is a relatively common referral to neuroradiology from many clinical specialities. The site of the pathology affecting the visual pathway can be…
Cranial Nerve Palsies 3-6
Cranial Nerve Palsies 3-6 Introduction Palsies of the 3rd to the 6th nerves can be caused by pathology anywhere along the length of the nerve from the superior orbital fissure…
Pituitary Imaging
Pituitary Imaging Introduction Magnetic resonance imaging is an excellent imaging modality for pituitary and optic chiasmal disease. However, MDCT is a proven accurate alternative if and when MR is not…
Orbital Pathology
Orbital Pathology Introduction The Royal College of Radiologists of the United Kingdom affirm that CT is the optimal investigation for orbital pathology because of the good spatial resolution and inherent…
Contrast Enhanced Brain Imaging
Contrast Enhanced Brain Imaging Introduction Since the development of brain CT in the early 1970s, intravenous iodinated contrast enhanced brain imaging has been recognized as providing additional information. It improves…
Routine Noncontrast Brain Imaging
Routine Noncontrast Brain Imaging Introduction Using a modern multidetector computed tomography (MDCT) system, ‘routine’ brain scanning should usually be performed using incremental techniques. Scanning incrementally, rather than helically, gives high…
End-of-Life Issues in Neurology
End-of-Life Issues in Neurology Informed consent: patient may accept or refuse treatment or diagnostic test after learning about anticipated benefits, risks, and alternative options. Patient autonomy requires accurate information about…
Neurologic Rehabilitation
Neurologic Rehabilitation Approaches: (a) bypass neurologic impediment by teaching adaptive techniques using preserved neurologic function (e.g., practice using normal hand for person with paretic arm); (b) facilitate return of neurologic…
