Abstract:

Objective　To investigate the value of vascular wall high-resolution magnetic resonance imaging (MRI) in the differential diagnosis of atherosclerosis and acute arteritis. Methods　A total of 60 patients who were suspected of atherosclerosis or acute arteritis and admitted to Liaocheng Third People's Hospital from October 2020 to October 2022 were enrolled, including 42 patients with atherosclerosis (an atherosclerosis group) and 18 patients with acute arteritis (an arteritis group). There were 32 males and 28 females; they were 32-75 years old. The general data and vascular wall high-resolution MRI characteristics of the two groups were compared. t and χ² tests were applied. Results　There were statistical differences in age, hypertension, hyperhomocysteinemia, morphology of diseased vessels, signals on T1 weighted imaging (T1WI)/T2 weighted imaging (T2WI), range of diseased vessels, vessel wall thickening mode, enhanced vascular wall, and deep tiny flow voids (DTFV) between the two groups (t=10.60; χ²=14.95, 4.37, 8.74, 6.75, 7.70, 20.68, 13.02, and 25.71; all P<0.05). The logistic regression receiver operating characteristic curve (ROC) found that the area under curve (AUC) of the combination of multifocal lesions and eccentric thickening in the differential diagnosis of atherosclerosis and acute arteritis was 0.871 (95%CI 0.759-0.944); when the cut-off value was 0.551, the sensitivity and specificity were 83.33% and 77.78%, respectively. Conclusion　Vascular wall high-resolution MRI is of high value in the differential diagnosis of atherosclerosis and acute arteritis.
