Abstract

Objective: Evaluate the imaging characteristics and diagnostic value of 1.5 Tesla magnetic resonance imaging (MRI) in detecting suspicious breast cancer lesions. Subjects and methods: A cross-sectional study was conducted at the National Cancer Hospital from June 2020 to June 2022, involving 82 patients with suspicious breast lesions who underwent 1.5 Tesla MRI examinations. Both imaging and pathological features were analyzed. Results: Regarding morphological characteristics on MRI: Mass-like lesions were observed in 80.6% of breast cancer cases. Malignant features included irregular shape, uncircumscribed margins, and rim enhancement, present in 73.6% of cases. Benign tumors were suggested by oval shapes, circumscribed margins, and non-enhancing internal septations features. Regarding signal features on MRI: Most lesions exhibited hyperintensity on STIR images. Rapid uptake in the initial post-contrast phase indicated the malignant nature of the lesions. Conclusion: Mass-like lesions with irregular shapes, uncircumscribed margins, and rim enhancement are indicative of breast cancer. Conversely, features such as oval shapes, circumscribed margins, and non-enhancing internal septations suggest benign lesions.
