Summary
Intravoxel incoherent motion (IVIM) and diffusion kurtosis imaging (DKI) effectively differentiate soft-tissue tumours (STTs). Distributed diffusion coefficient (DDC) and mean kurtosis (MK) show high diagnostic value in classifying tumour malignancy.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Soft-tissue tumours (STTs) present a diagnostic challenge.
- Differentiating benign, intermediate, and malignant STTs is crucial for treatment planning.
- Advanced MRI techniques like IVIM and DKI offer potential for improved characterization.
Purpose of the Study:
- To evaluate the efficacy of IVIM and DKI in differentiating benign, intermediate, and malignant STTs.
- To identify specific IVIM and DKI parameters with high diagnostic performance.
Main Methods:
- Prospective study of 100 STT patients.
- Acquisition of IVIM and DKI parameters including ADC, f, Dslow, Dfast, α, DDC, MD, and MK.
- Statistical analysis using ROC curves and Kruskal-Wallis H test.
Main Results:
- ADC, Dslow, DDC, and MD decreased progressively from benign to malignant STTs.
- Higher MK values were observed in malignant STTs compared to benign and intermediate.
- DDC demonstrated excellent differentiation between benign and non-benign STTs (AUC up to 0.892).
Conclusions:
- IVIM and DKI parameters are valuable tools for differentiating STT grades.
- DDC and MK show significant diagnostic efficacy, complementing conventional MRI.
- These advanced imaging techniques can aid in clinical decision-making for STTs.
