Summary
T1rho-weighted imaging effectively differentiates malignant from benign breast lesions. Combining T1rho with apparent diffusion coefficient (ADC) and time to peak (TTP) significantly improves diagnostic accuracy, offering a valuable addition to conventional MRI for breast cancer detection.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Distinguishing malignant from benign breast lesions is crucial for appropriate patient management.
- Conventional MRI techniques have limitations in achieving high diagnostic accuracy.
Purpose of the Study:
- To evaluate the feasibility of T1rho-weighted imaging in differentiating malignant and benign breast lesions.
- To assess the added diagnostic value of T1rho-weighted imaging to conventional MRI parameters.
Main Methods:
- Prospective enrollment of 113 women with breast lesions.
- Acquisition of preoperative T1rho-weighted imaging, diffusion-weighted imaging (DWI), and dynamic contrast-enhanced MRI (DCE-MRI).
- Comparison of T1rho values, apparent diffusion coefficient (ADC), and DCE-MRI parameters (e.g., time to peak) between benign and malignant groups using ROC curve analysis.
Main Results:
- Mean T1rho values were significantly higher in benign lesions (92.61 ± 22.10 ms) compared to malignant lesions (72.18 ± 16.37 ms) (P < 0.001).
- Malignant lesions exhibited lower ADC and time to peak (TTP) values than benign lesions (all P < 0.001).
- The combination of T1rho, ADC, and TTP achieved an AUC of 0.896, with 81.0% sensitivity and 87.1% specificity, significantly outperforming ADC and TTP alone.
Conclusions:
- T1rho-weighted imaging is a feasible MRI technique for differentiating malignant from benign breast lesions.
- The combination of T1rho, ADC, and TTP enhances diagnostic performance, particularly specificity and sensitivity.
- T1rho-weighted imaging shows promise as a supplementary tool to conventional MRI in breast lesion characterization.
