Blood-Spinal Cord Barrier Permeability in Experimental Spinal Cord Injury: Dynamic Contrast-Enhanced Magnetic Resonance Imaging
Following the primary traumatic injury, spinal cord tissue undergoes a series of pathobiological changes, including compromised blood-spinal cord-barrier (BSCB) integrity. These vascular changes occur over both time and space. In an experimental model of spinal cord injury (SCI), longitudinal dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)studies were performed up to 56 days post...
متن کاملContrast enhanced ultrasound imaging for assessment of spinal cord blood flow in experimental spinal cord injury.
Reduced spinal cord blood flow (SCBF) (i.e., ischemia) plays a key role in traumatic spinal cord injury (SCI) pathophysiology and is accordingly an important target for neuroprotective therapies. Although several techniques have been described to assess SCBF, they all have significant limitations. To overcome the latter, we propose the use of real-time contrast enhanced ultrasound imaging (CEU)...
متن کاملEvaluating regional blood spinal cord barrier dysfunction following spinal cord injury using longitudinal dynamic contrast-enhanced MRI
BACKGROUND In vivo preclinical imaging of spinal cord injury (SCI) in rodent models provides clinically relevant information in translational research. This paper uses multimodal magnetic resonance imaging (MRI) to investigate neurovascular pathology and changes in blood spinal cord barrier (BSCB) permeability following SCI in a mouse model of SCI. METHODS C57BL/6 female mice (n = 5) were sub...
متن کاملPOST-TRAUMATIC CHRONIC SPINAL CORD INJURY: ASSESSMENT WITH MRI
The initial experience concerning the use of magnetic resonance imaging in 94 patients who had sustained chronic cord injury showed its specific advantages over traditional imaging modalities. A variety of 84 cord abnormalities were identified including myelomalacia in 47%, cord cysts in 37%, focal atrophy in 11 % and cord transection in 5%. Canal stenosis was seen in twenty-five patients, ...
متن کاملManganese-enhanced MRI Offers Correlation with Severity of Spinal Cord Injury in Experimental Models
BACKGROUND Spinal cord injuries (SCI) are clinically challenging, because neural regeneration after cord damage is unknown. In SCI animal models, regeneration is evaluated histologically, requiring animal sacrifice. Noninvasive techniques are needed to detect longitudinal SCI changes. OBJECTIVE To compare manganese-enhanced magnetic resonance imaging (MRI [MEMRI]) in hemisection and transecti...
