Abstract:
Objective:To compare the diagnostic efficacy of ultrasound and MRI in fibro-adipose vascular anomaly (FAVA).Methods:The clinical data of patients with suspected FAVA who underwent ultrasound and MRI examinations at Henan Provincial People’s Hospital from January 2011 to October 2021 were retrospectively analyzed. The imaging findings from ultrasound and MRI were analyzed, and then compared with the pathological findings. To evaluate the diagnostic efficacy of ultrasound and MRI in diagnosing FAVA by assessing sensitivity, specificity, positive predictive value, negative predictive value, and coincidence rate. Paired χ2 test (McNemar test) was used to compare the coincidence rate of ultrasound and MRI, as well as their combined diagnosis. A significance level of P < 0.05 was considered statistically significant. Results:A total of 50 patients were included in the study, comprising 24 males and 26 females, with their ages ranging from 1 to 50 years and an average age of (16.2 ± 10.5) years. Pathology confirmed 43 FAVA patients and 7 non-FAVA patients. The sensitivity, specificity, positive predictive value, negative predictive value, and coincidence rate of ultrasound in the diagnosis of FAVA were 83.7%, 71.4%, 94.7%, 41.7%, and 82.0%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and coincidence rate of MRI in the diagnosis of FAVA were 69.8%, 85.7%, 96.8%, 31.6%, and 72.0%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and coincidence rate of FAVA were 90.7%, 71.4%, 95.1%, 55.6%, and 88.0%, respectively. The diagnostic accuracy of ultrasound was higher than that of MRI, but the difference was not statistically significant ( χ2 = 1.41, P = 0.235). The coincidence rate of combined diagnosis was higher than that of ultrasound ( χ2= 0.71, P = 0.401) and MRI ( χ2= 4.00, P = 0.039), with a statistically significant difference. Conclusion:Both ultrasound and MRI are highly valuable in diagnosing FAVA. The combined usage of ultrasound and MRI can enhance the accuracy of preoperative FAVA diagnosis.
