Abstract

Purpose To identify a method of assessing cerebral 2-deoxy-2-[18 F]fluoro-D-glucose ([18 F]FDG) metabolism with an asymmetry index (AI) that reflects clinical neurological function in patients with ischemic cerebrovascular disease (ICVD), and to explore its applications and potential value to the ICVD in clinical settings. Procedures: Seventy patients diagnosed with subacute and chronic ischemic stroke were retrospectively analyzed. All patients underwent [18 F]FDG PET/MR scans and were assessed using the National Institutes of Health Stroke Scale (NIHSS) and the Modified Rankin Scale (mRS). Following a year of rehabilitation training, nineteen patients underwent a repeat [18 F]FDG PET/MR scan. The decreased cerebral [18 F]FDG metabolism region was defined as the AI value greater than 10%. Two voxel-wise AIs, designated as AI 1 and AI 2, were calculated based on the standardized uptake value ratio (SUVR). The decreased metabolism on affected side accessed by different AI calculation methods were compared. The correlations between the decreased metabolism and the clinical scores were analyzed. Results The volume and percentage of decreased [18 F]FDG metabolism assessed by AI 2 was larger than that obtained from AI 1 (all p < 0.0001). The correlation coefficients between the clinical scores and the decreased metabolism in temporal and parietal lobes assessed by AI 1 method were all higher than those from AI 2. In addition, the improved follow-up patients showed more pronounced metabolic improvement as assessed by AI 1. Conclusions The assessment of cerebral [18 F]FDG metabolism in patients with unilateral internal carotid/middle cerebral artery steno-occlusion to reflect clinical neurological function using the AI 1 method demonstrated superior performance in comparison to the AI 2 method.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
