Assessment of reduced field of view in diffusion tensor imaging of the lumbar nerve roots at 3 T.

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
objectivesTo assess the value of reduced field of view (rFOV) imaging in diffusion tensor imaging (DTI) and tractography of the lumbar nerve roots at 3 T from the perspective of future clinical trials.
methodsDTI images of the lumbar nerves were obtained in eight healthy volunteers, with and without the rFOV technique. Non-coplanar excitation and refocusing pulses associated with outer volume suppression (OVS) were used to achieve rFOV imaging. Tractography was performed. A visual evaluation of image quality was made by two observers, both senior musculoskeletal radiologists. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured in L5 and S1 roots.
resultsrFOV images of the L5 and S1 roots were assessed as being superior to full FOV (fFOV) images. Image quality was rated as good to excellent by both observers. Interobserver agreement was good. No significant difference was found in FA and ADC measurements of the L5 or S1 roots. On the contrary, only poor-quality images could be obtained with fFOV imaging as major artefacts were present.
conclusionThe rFOV approach was essential to achieve high-quality DTI imaging of lumbar nerve roots on 3-T MRI. KEY POINTS: • Diffusion tensor 3-T MR imaging of lumbar nerve roots creates severe artefacts. • A reduced field of view drastically reduces artefacts, thereby improving image quality. • Good-quality tractography images can even be obtained with rFOV imaging. • rFOV DTI is better than fFOV DTI for clinical studies.
