Ultra-High Field Spinal Cord Imaging
Abstract Magnetic resonance imaging (MRI) of the human spinal cord in vivo suffers from multiple practical limitations: low signal-to-noise ratio, the need for high resolution, and the detrimental influence of…
Traumatic Spinal Cord Injury: Acute Spinal Cord Injury and Prognosis
Abstract Prior to the widespread use of magnetic resonance imaging (MRI), the diagnosis of acute traumatic spinal cord injury (SCI) was largely based on clinical history, physical examination, plain film…
Traumatic Spinal Cord Injury: Chronic Spinal Cord Injury and Recovery
Abstract The introduction of magnetic resonance imaging (MRI) to the field of spinal cord injury (SCI) has vastly improved the diagnosis of injury level and severity as well as the…
Inflammatory Demyelinating Diseases
Abstract The spinal cord is commonly affected in inflammatory demyelinating diseases (IDD) of the central nervous system. In the most common IDD, multiple sclerosis (MS), the importance of spinal cord…
Rationale for Quantitative MRI of the Human Spinal Cord and Clinical Applications
Abstract In vivo spinal cord imaging is now commonly used to diagnose patients with neurodegenerative disorders. Quantitative MRI (qMRI) techniques applied to the spinal cord show promise for predicting prognosis…
Radiographic Anatomy of the Orbit and Visual Pathways
Chapter contents I. COMPUTED TOMOGRAPHY SCANS 50 A. Computed tomography: axial cranial bone anatomy 50 B. Computed tomography: coronal cranial bone anatomy 56 C. Computed tomography: sagittal cranial bone anatomy…
Anatomy of the Intracranial Visual Pathways
Intracranial anatomy is highly complex and well beyond the scope of this book. However, a number of structures are closely related to visual function and form the neural pathways for…
Magnetic Resonance Imaging
Magnetism is a property of matter. It results from electrons orbiting around atoms, and these spinning electrons cause the atom to have a magnetic moment. The magnetic field strength is…
Anatomy of the Orbit
The skull is composed of two segments, the cranium and the face. The cranium is the major portion and it consists of three unpaired bones, the sphenoid, occipital, and ethmoid…
Computed Tomography
In 1895 the German physicist Wilhem Konrad Röntgen discovered X-rays. He was awarded the first Nobel Prize in physics in 1901 for this discovery. Medical imaging based on this technology…
