Mammary Gland Fiber Adenoma Imaging Diagnostic Reserch

Purpose: Combined with clinical pathologic result analysis of themammary gland fiber adenoma MRI and X-ray mammography image features,at the same time discussed the MRI performance score and MRI BI-RADSclassification of the correlation.Methods: Retrospective analysis in July2011to February2012to ourclinic or hospital MRI line by surgery and pathology diagnosis of mammarygland fiber adenoma of27patients ’(35lesions) material, observed the clinicaland MRI imaging findings (including T1, T2lesions weighted signal pressurefat sequence signal, size, shape, edge, location, and strengthen the form, initialstrengthen rate, the initial period signal change); There are19patients do X-raymammography check, and observe the patient of X-ray mammography imageperformance (including mass shape, edge, density, calcification, structuredistortion, local asymmetric density, inverted nipples, etc.).Result:27patients were found with clinical breast lumps attendance.MRI imaging performance: the T1-weighted sequence of signals of lesions32,lower or low signal lesions have3; T2-weighted pressure fat sequence high signal lesions have28, the focus of the low signal have6, the mixed signals is1;Lesions minimum0.8cm,7.7cm biggest; The focus of the circular shape for the2, for the oval lesions14, for polygonal lesions19; The focus of the clear edgefor28, edge blur the focus of the edge for7; Position: the upper outer quadrantright breast are8lesions, under outer the right breast quadrant are4lesions, theupper within quadrant right breast quadrant are5lesions, the within under rightbreast quadrant is1lesion, the upper outer quadrant left breast quadrant are6lesions, under outer the right breast quadrant are2lesions, the upper withinquadrant right breast quadrant are5lesions, the within under right breastquadrant are3lesions, the left breast is1lesion. Improved form for uniformityof the lesions are22, strengthen the heterogeneity are the focus of6, strengthenthe form of a space,separated like to strengthen are7lesions.The initialstrengthen rate <50%of the lesions are8, and50%~100%of the lesions have2,>100%of the lesions are25; After the initial period signal changes: durationhave25lesions, the platform period have6lesions, outflow reduce have4lesions. MRI BI-RADS score:0points have3lesions,1points with5lesions,2points have14lesions,3points with8lesions,4points have3lesions,5pointshave2lesions; The corresponding BI-RADS classification for Ⅰclassificationhas8lesions, Ⅱ classification14lesions, Ⅲ classification8lesions, Ⅳclassification has5lesions.X-ray mammography image performance: not foundlumps cases has8,5for mammary gland hyperplasia,3for local asymmetricdensity; Find mass11cases in which10performance for round, oval, one for the lobulated; Edge clear10, edge blur1,Mass high density5, and6equidensity;Coarse particle calcification1,Inverted nipples1.Conclusion: The MRI can clearly show mammary gland fiber adenoma,the shape, the edge, and strengthen the form, after post-processing can moreexplicitly show the early lesion enhancement ratio and enhanced signal changesin the initial period. MRI BI-RADS score points less than or equal3for benign,its and MRI BI-RADS classification’s coincidence rate was85.7%, after SPSSsoftware analysis MRI BI-RADS score and MRI BI-RADS classification haveobvious positive correlation, pearson correlation coefficient is0.967.X-raymammography diagnosis was53.6%. MRI and X-ray mammography checkmammary gland fiber adenoma is the diagnostic accordance with a statisticalsignificance.
