Summary
Contrast-enhanced MRI effectively evaluates suspicious breast lesions. This magnetic resonance imaging technique aids in diagnosing breast cancer and other abnormalities with high accuracy.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Equivocal findings on mammography and clinical examination necessitate advanced imaging techniques.
- Magnetic resonance imaging (MRI) offers superior soft-tissue contrast for breast lesion evaluation.
Purpose of the Study:
- To assess the diagnostic accuracy of contrast-enhanced MRI in evaluating suspicious breast lesions.
- To determine the effectiveness of T1-weighted spin-echo (SE) and gradient-echo (FFE) sequences with Gadolinium DTPA.
Main Methods:
- MRI of the breasts was performed on 296 patients with equivocal findings.
- T1-weighted SE and FFE sequences were acquired before and after Gadolinium DTPA administration.
- Lesions showing enhancement were biopsied for histopathological analysis.
Main Results:
- Fifty enhancing lesions were biopsied, revealing 26 carcinomas, 17 cases of proliferating mastopathy, 5 fibroadenomas, and 1 abscess.
- Contrast-enhanced MRI demonstrated high diagnostic accuracy in differentiating benign from malignant breast lesions.
Conclusions:
- Contrast-enhanced MRI, utilizing 2D-SE and FFE sequences, is a highly effective tool for evaluating suspicious breast lesions.
- This imaging modality provides high diagnostic accuracy, aiding in the timely and precise diagnosis of breast abnormalities.
