Diagnostic value of 3D-TOF-MRA combined with MRI detection for primary trigeminal neuralgia
Objective To explore the diagnostic value of three dimensional time of flight magnetic resonance angiography(3D-TOF-MRA)combined with magnetic resonance imaging(MRI)for primary trigeminal neuralgia(PTN).Methods A total of 78 PTN patients who visited Henan Provincial Hospital of Traditional Chinese Medicine from March 2022 to January 2024 were collected.There were 36 males and 42 females,the age was 27-76(50.84±10.47)years old,and there were 31 left side lesions and 47 right side lesions.The 3D-TOF-MRA imaging features were analyzed,and MRI parameters of the affected and healthy sides of the PTN patients were compared.The diagnostic results of different examination methods were statistically compared,and the diagnostic efficacy was further analyzed.Paired t test and x2 test were used.Results The trigeminal root(TR)area and nerve pontine angle[(23.86±3.86)mm2 and(39.62±6.75)°]on the affected side were smaller than those on the healthy side[(28.11±3.19)mm2 and(44.13±7.31)°](both P<0.05).There were no statistically significant differences in the TR length or the angle across the apex of the rock between the affected side and the healthy side(both P>0.05).The diagnostic sensitivity of 3D-TOF-MRA combined with MRI was 96.15%(75/78),which was higher than those of 3D-TOF-MRA[82.05%(64/78)]and MRI[78.21%(61/78)],and the missed diagnosis rate of 3D-TOF-MRA combined with MRI was 3.85%(3/78),which was lower than those of 3D-TOF-MRA[17.95%(14/78)]and MRI[21.79%(17/78)](P<0.05).The Kappa values of 3D-TOF-MRA,MRI,and 3D-TOF-MRA combined with MRI in the diagnosis of PTN of different grades were all>0.6,but the Kappa value of 3D-TOF-MRA combined with MRI was the highest,which was 0.826(all P<0.05).Conclusion The combined diagnosis of 3D-TOF-MRA and MRI can significantly improve the diagnostic sensitivity of PTN,reduce the missed diagnosis rate,and has high consistency,which is beneficial for clinical selection of treatment plans and improvement of quality of life.
