|Differential diagnosis of soft tissue tumours by using semi-quantitative and quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging|
Methods and materials
Totally 45 patients with pathologically confirmed soft tissue tumours (15 benign tumours and 30 malignant tumours) underwent DCE-MRI. The semi-quantitative parameters were as follows: time to peak (TTP), maximum concentration (MAX Conc.), area under curve of time-concentration curve (AUC-TC), and maximum rise slope (MAX Slope). Quantitative DCE-MRI was analysed with the Extended Tofts–Kety model to obtain the following quantitative parameters: Ktrans, Kep, and Ve. Data were evaluated using the independent t test or Mann–Whitney U test analysis and receiver operating characteristic (ROC) curves. The following groups of tissues were compared: benign tumours and normal tissues, malignant tumours and normal tissues, benign tumours and malignant tumours, and benign control groups and malignant control groups.
