“…Consequently, the increase of ADC and RD is congruent to the decrease in FA, yet reflecting different aspects of diffusion properties. Interestingly, RD has been shown to be the most sensitive parameter for detection of lateral spinal cord compression in patients suffering from cervical spondylosis [3], a phenomenon that primarily affects the myelin sheath [2]. On the contrary, and consistent with our results, AD is primarily affected by axonal pathologies, rather than by neuronal compression [25].…”

“…Diffusion tensor imaging (DTI) has been shown to complement morphological MRI in the assessment of neuronal integrity [1,2]. Spinal DTI can detect subtle spinal cord damage of functional relevance in cervical spondylosis, even in the absence of corresponding signal alteration on T2-weighted (T2w) images [3]. Other studies revealed a correlation of DTI with clinical and electrophysiological measures in patient suffering from chronic spinal cord injury [4] or amyotrophic lateral sclerosis [5].…”

“…Processes include inflammatory and demyelinating diseases [94], such as multiple sclerosis [95][96][97][98][99][100][101][102][103][104], neuromyelitis optica [105][106][107][108][109][110][111][112], and acute disseminated encephalomyelitis [54]. Other inflammatory causes, such as neurosarcoidosis [113]; neoplasms such as lymphoma [114] and metastases as well as paraneoplastic syndromes [115]; nutritional deficiencies, such as B12 deficiency [116] and copper deficiency; infections affecting the cord, such as neurosyphilis; degenerative changes in the vertebral bodies and discs [117,118]; or ossification of the posterior longitudinal ligament [119] that lead to cord compression and edema. Vascular lesions, such as spinal dural arteriovenous fistulae, can also cause cord edema and resultant ataxia [120,121].…”

Ataxia can result from an abnormality in the cerebellum, spinal cord, peripheral nerves, and/or vestibular system. Pathology involving the brain, such as infarct or hydrocephalus, can also present with ataxia as part of the symptom constitution, or result in symptoms that mimic ataxia. Clinical evaluation by history and careful neurological examination is important to help with lesion localization, and helps determine where imaging should be focused. In the setting of trauma with the area of suspicion in the brain, a head CT without intravenous contrast is the preferred initial imaging choice. If vascular injury is suspected, CTA of the neck can be helpful. When the area of suspicion is in the spine, CT or MRI of the spine can be considered to assess for bony or soft-tissue injury, respectively. In the setting of ataxia unrelated to recent trauma, MRI is the preferred imaging modality, tailored to assess the brain or spine depending on the area of suspected pathology. The use of intravenous contrast is generally helpful.

“…DWN and DTN have also shown their ability to detect these morphological abnormalities in animal models, but adding pathophysiological and functional data (27). Further studies are needed to determine if these functional techniques may even detect abnormalities in PN without relevant findings on the conventional morphological studies as occurs in other anatomical areas such as in CNS or spinal cord (31,32).…”

Traumatic conditions of peripheral nerves and plexus have been classically evaluated by morphological imaging techniques and electrophysiological tests. New magnetic resonance imaging (MRI) studies based on 3D fat-suppressed techniques are providing high accuracy for peripheral nerve injury evaluation from a qualitative point of view. However, these techniques do not provide quantitative information. Diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI) are functional MRI techniques that are able to evaluate and quantify the movement of water molecules within different biological structures. These techniques have been successfully applied in other anatomical areas, especially in the assessment of central nervous system, and now are being imported, with promising results for peripheral nerve and plexus evaluation. DWI and DTI allow performing a qualitative and quantitative peripheral nerve analysis, providing valuable pathophysiological information about functional integrity of these structures.In the field of trauma and peripheral nerve or plexus injury, several derived parameters from DWI and DTI studies such as apparent diffusion coefficient (ADC) or fractional anisotropy (FA) among others, can be used as potential biomarkers of neural damage providing information about fiber organization, axonal flow or myelin integrity. A proper knowledge of physical basis of these techniques and their limitations is important for an optimal interpretation of the imaging findings and derived data. In this paper, a comprehensive review of the potential applications of DWI and DTI neurographic studies is performed with a focus on traumatic conditions, including main nerve entrapment syndromes in both peripheral nerves and brachial or lumbar plexus.
