- Abstract:
- Objective To explore the application value of high-resolution magnetic resonance imaging (HRMRI) in the diagnosis of intracranial arterial diseases. Methods A total of 62 patients with intracranial arterial diseases who were admitted to Handan First Hospital between January 2017 and December 2018 were enrolled. All patients were examined with HRMRI and digital subtraction angiography (DSA). DSA was taken as the gold standard when calculating the coincidence rate of HRMRI diagnosis on the types of intracranial arterial diseases, and the consistency between the diagnostic results of HRMRI and DSA was tested by Kappa. With DSA as the gold standard, the coincidence rate of HRMRI diagnosis on intracranial artery stenosis was also calculated, and the consistency between the diagnostic results of HRMRI and DSA was tested by Kappa. Results In 62 cases, 44 cases of atherosclerosis, 11 cases of vasculitis and 7 cases of arterial dissection were diagnosed by DSA; while 43 cases of atherosclerosis, 13 cases of vasculitis and 6 cases of arterial dissection were diagnosed by HRMRI, and the coincidence rate between the diagnostic results of two methods was 90.32% (56/62), with a Kappa value of 0.864. Moreover, DSA examination showed that there were 9 cases of mild stenosis, 26 cases of moderate stenosis and 27 cases of severe stenosis, while HRMRI examination showed that there were 7 cases of mild stenosis, 24 cases of moderate stenosis and 31 cases of severe stenosis. The two methods had a high coincidence rate (Kappa value=0.812) which was 83.87% (52/62). Conclusion HRMRI can clearly show the wall and lumen of vessels, and there is high consistency between HRMRI and DSA in the identification and classification of intracranial arterial disease types and degree of stenosis. Therefore, HRMRI can be promoted in the clinical diagnosis of intracranial arterial diseases.
