| Objective: To explore the imaging characteristics and diagnosis value of MRI and CT in the diagnosis of venous malformations of the head and neck.Methods:The data comes from the clinical and imaging data of 68 suspected head and neck venous malformations admitted to our hospital from March 2017 to October 2020.Retrospectively describe and analyze the MRI and CT features of venous malformations in the head and neck.The sensitivity,specificity,and diagnostic accuracy of the two inspection methods are compared.Results: 1)The sensitivity,specificity,and diagnostic accuracy of MRI and CT in the diagnosis of venous malformations were MRI: 97.5%,33.33%,93.02%,and CT: 83.78%,50%,82.05%.The sensitivity of MRI was higher than that of CT,and the difference was statistically significant(P<0.05).The specificity and diagnostic accuracy of MRI were not significantly different from CT(P>0.05).2)The detection rate of lesions is in order of combined examination,MRI only,and CT examination only(P<0.05).3)Among the confirmed patients,24 were male and 41 were female.The male to female ratio is 1:1.7.Age of them ranged from 10 months to 76 years old.The average age is(30.53±21.95)years old,and the median age is 28 years old.4)MRI and CT detected 222 out of 229 lesions.The common sites are the masseter muscle area of the parotid gland,the inner and outer pterygoid muscle area,and the submandibular area.The masses on the body surface are the most common as the first symptom.5)Irregular shapes and uneven enhancement lesions after enhancement are mostly presented in the image.6)T1 and T2 are slightly longer or longer signals are more common in MRI.Conclusion: The imaging imaging of venous malformations of the head and neck has certain characteristics,which can provide a certain reference basis for diagnosis.MRI is recommended as the first choice.CT can be used as a supplementary examination to clarify the condition of phlebolithiasis and bone. |
