The use of identified scoring system and quantitative data for evaluating magnetic resonance breast images enhanced by dinamic contrast methods

35197

Objective: To assess whether identified scoring system and various guantitative data would help clinicians to distinguishing malignant from benign breast lesions more accurately on the dynamic contrast enhanced-magnetic resonance images (DCE-MRI). Patients and Methods: Ninety-five lesions included in our research were evaluated by a scoring system (Fischer’s score) that can be accepted as an analogue of breast imaging-reporting and data systems (BI-RADS). Time to peak enhancement (Tpeak), maximum slope of enhancement curves (Smax) and washout values which are quantitative parameters computed from kinetic data were calculated. Results: In the evaluation the Fischer scoring system, specificities of total points 0-3, 4 and 5-8 were 23.40%, 78.87% and 97.87% respectively. The parameters of the scoring system showed that the shape of a lesion which is one of the morphologic characteristics, was statistically the most significant parameter (p=0.001). Rim enhancement had the highest specificity (97.87%) of the morphologic parameters. There was no significant difference between malignant and benign lesions in the percentage of early enhancement when we examined the kinetic data. There was significant difference between kinetic curves of type 1 compared to types 2-3 (p=0.001). The quantitative parameters Tpeak and Smax, were statistically significant. Conclusion: Scoring systems in which both morphologic parameters and kinetic curves are evaluated give useful information in distinguishing benign from malignant breast lesions. Also, statistically significant Tpeak and Smax quantitative values can be useful in the diagnosis of breast lesions.
