Early Detection of Neuroinflammation and White Matter Damage Following Dorsal Spinal Nerve Root Sectioning in a Nonhuman Primate Model.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeDorsal rhizotomy, or spinal dorsal nerve root lesioning, is a surgical procedure used to treat intractable nerve pain by selectively severing sensory afferent nerve roots. This study aimed to evaluate whether multiparametric MRI, including diffusion tensor imaging (DTI), quantitative magnetization transfer (qMT), chemical exchange saturation transfer (CEST), and relayed nuclear Overhauser enhancement (rNOE), can sensitively detect structural and biochemical changes in the intact spinal cord following a focal dorsal nerve root section in a nonhuman primate model.
methodsIn four squirrel monkeys, unilateral dorsal nerve roots at cervical segments C4 and C5 were surgically transected. MRI data were collected using a 9.4 T scanner with a custom saddle-shaped transmit-receive quadrature coil before and 1 week after lesioning. DTI-derived fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD); qMT-derived pool size ratio (PSR); and CEST and rNOE effects extracted from five-pool Lorentzian fitting of Z-spectrum, were quantified across seven regions of interest.
resultsAt the lesioned dorsal nerve root bundles, FA, PSR, and rNOE (-1.6 ppm) values decreased, while RD and CEST (3.5 ppm) increased, consistent with fiber degeneration, demyelination, and inflammation. Similar, though less pronounced, changes were observed in the dorsal root entry zone, particularly within the first week post-lesion.
conclusionMultiparametric MRI enables region-specific detection of spinal cord pathology, including axonal degeneration, demyelination, and possible neuroinflammation, as early as 1 week after dorsal nerve root injury. These results demonstrate its promise for noninvasive monitoring of post-injury pathology and for evaluating therapeutic efficacy.
