ARTICLE HIGHLIGHTS
Research background
The judgement of neurovascular compression (NVC) is a critical step in the preoperative evaluation of microvascular decompression (MVD). Three-dimensional time-of-flight magnetic resonance angiography (3D TOF MRA) combined with high resolution T2-weighted imaging (HR T2WI) is considered to be a more effective method to detect NVC.
Research motivation
To assess the value of 3D TOF MRA combined with HR T2WI in the preoperative evaluation of MVD.
Research objectives
To determine the diagnostic value of 3D TOF MRA combined with HR T2WI in the judgment of NVC.
Research methods
Related studies published from inception to September 2022 based on PubMed, Embase, Web of Science, and the Cochrane Library were retrieved. A meta-analysis was performed using the MIDAS module of STATA 16.0 software. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR), the area under the receiver operating characteristic curve (AUROC), and 95% confidence intervals (CIs) were calculated.
Research results
Our search identified 595 articles, of which 12 (including 855 patients) fulfilled the inclusion criteria. The pooled sensitivity and specificity of 3D TOF MRA combined with HR T2WI for detecting NVC were 0.96 (95%CI: 0.92-0.98) and 0.92 (95%CI: 0.74-0.98), respectively. The pooled PLR was 12.4 (95%CI: 3.2-47.8), pooled NLR was 0.04 (95%CI: 0.02-0.09), and pooled DOR was 283 (95%CI: 50-1620). The AUROC was 0.98 (95%CI: 0.97-0.99).
Research conclusions
3D TOF MRA combined with HR T2WI has excellent sensitivity and specificity for judging NVC in patients with trigeminal neuralgia or hydrosalpinx fluid.
Research perspectives
3D TOF MRA combined with HR T2WI can be used as an effective tool for preoperative evaluation of MVD.
