Percutaneous Treatment of Spinal Metastases
Percutaneous image-guided minimally invasive thermal ablation and vertebral augmentation are robust techniques, part of the available armamentarium used by radiologists for the management of patients with spinal metastases. Such interventions have been established to be safe and effective in treatment of selected patients with vertebral metastases. Special attention to procedure techniques including choice of ablation modality, vertebral augmentation technique, and thermal protection is essential for improved patient outcomes.

Dynamic Contrast-Enhanced MR Perfusion
Recent therapeutic advances have led to increased survival times for patients with metastatic disease. Key to survival is early diagnosis and subsequent treatment as well as early detection of treatment failure allowing for therapy modifications. Conventional MR imaging techniques of the spine can be at times suboptimal for identifying viable tumor, as structural changes and imaging characteristics may not differ pretreatment and posttreatment. Advanced imaging techniques such as DCE-MRI can allow earlier and more accurate noninvasive assessment of viable disease by characterizing physiologic changes and tumor microvascula...

Intradural Extramedullary Tumors and Associated Syndromes
Most intradural tumors are located within the intradural extramedullary compartment, and the most common tumors are schwannomas and meningiomas. Other less common neoplasms include neurofibroma, solitary fibrous tumor, myxopapillary ependymoma, lymphoma, metastatic leptomeningeal disease, malignant peripheral nerve sheath tumor, and paraganglioma. Patients usually present with gait ataxia, radicular pain, and motor and sensory deficits due to chronic compressive myelopathy or radiculopathy. MRI is the modality of choice for detecting and evaluating intradural extramedullary spinal tumors. This imaging technique helps narro...

MRI and Traumatic Brain Injury: Where Are We Heading?
Traumatic brain injury (TBI) is currently very much in the public consciousness. A quick Google search reveals over 150 million TBI-related hits, including several National Institute of Neurological Disorders and Stroke, Department of Defense, and even National Football League (NFL) funded initiatives, such as the National Institutes of Health –sponsored TRACK-TBI study. I was therefore delighted when Drs Maralani and Symons invited me to write this introduction for their issue on “MRI and Traumatic Brain Injury,” for this issue of the Neuroimaging Clinics series.

Perfusion Imaging of Traumatic Brain Injury
The mechanisms for regulating cerebral blood flow (CBF) are highly sensitive to traumatic brain injury (TBI). The perfusion imaging technique may be used to assess CBF and identify perfusion abnormalities following a TBI. Studies have identified CBF disturbances across the injury severity spectrum and correlations with both acute and long-term indices of clinical outcome. Although not yet widely used in the clinical context, this is an important area of ongoing research. (Source: Neuroimaging Clinics)

Traumatic Brain Injury and Vision
Traumatic brain injury disrupts the complex anatomy of the afferent and efferent visual pathways. Injury to the afferent pathway can result in vision loss, visual field deficits, and photophobia. Injury to the efferent pathway primarily causes eye movement abnormalities resulting in ocular misalignment and double vision. Injury to both the afferent and efferent systems can result in significant visual disability. (Source: Neuroimaging Clinics)

The Current State of Susceptibility-Weighted Imaging and Quantitative Susceptibility Mapping in Head Trauma
Susceptibility-weighted imaging (SWI) is a MR imaging technique suited to detect structural and microstructural abnormalities in traumatic brain injury (TBI). This review article provide an insight in to the physics principles of SWI and its clinical application in unraveling the complex interaction of the biophysical mechanisms of head injury. Literature evidences support SWI as the most ideal sequence in detection of microbleeds, which is the “tip of the iceberg” biomarker of microvascular injuries. The review also detailed the emerging advance techniques of Quantitative susceptibility mapping (QSM) and artificial in...
