- Diffusion-weighted breast imaging at 3 T: Preliminary experiencePublication . Nogueira, Luisa; Brandão, S.; Matos, E.; Nunes, R. G.; Ferreira, H. A.; Loureiro, J.; Ramos, I.To evaluate the performance of diffusion-weighted imaging (DWI) at 3 T for the detection and characterization of breast lesions.
- Editorial for "Radiomics based on multimodal MRI for the differential diagnosis of benign and malignant breast lesions"Publication . Nogueira, Luisa; Nunes, R. G.Breast magnetic resonance imaging (MRI) is widely used to detect and characterize lesions, presenting good sensi- tivity but moderate specificity. To improve accuracy, new MRI sequences are continuously being sought. Diffusion- weighted imaging (DWI) probes the lesions’ cellularity, improving specificity. However, the distributions of the apparent diffusion coefficients (ADCs) for different lesion types show an overlap. Extensions to the monoexponential DWI model have thus been proposed such as diffusion- kurtosis imaging (DKI).
- Influence of the minimum b-value on prostate cancer assessment using conventional DWI and DKI modelsPublication . Adubeiro, N.; Nogueira, L.; Nunes, R. G.; Ferreira, H. A.; Ribeiro, E. F. C.; Fuente, J. M. LaTo investigate the influence of the minimum b-value in diffusion parameters estimated for prostate tissues using mono-exponential and kurtosis models.
