Hintergrund Die kontrastmittelverstärkte MRT der Mamma ist das sensitivste Verfahren zum Nachweis von Brustkrebs. Der weiteren Verbreitung der Methode stehen der im Vergleich zur Mammographie komplizierte Untersuchungsablauf sowie die Notwendigkeit einer intravenösen Kontrastmittelgabe gegenüber. Fragestellung Kann die diffusionsgewichtete Bildgebung (DWI) die Kontrastmitteldynamik ersetzen und...
Diffusion-weighted imaging(DWI) visualizes the thermal motion of protons in tissue, which is less affected by the state of the background mammary gland and therefore has sufficient capability to diagnose DCIS as well as ILC. Of 30 patients with DCIS, sensitivity was 87%, and 4 cases were false negative (FN); of 30 patients with invasive lobular carcinoma ILC, the rate of true positive cases (TP) was...
Summary INTRODUCTION: Our purpose was to determine whether diffusion-weighted MR imaging (DWI) could be used in differentiation of benign and malign breast lesions. MATERIALS AND METHODS: 41 women patients were included in the study. 45 lesions were diagnosed by biopsy; 25 (55.5%) of these lesions were malignant and 20 (44.5%) were benign. The apparent diffusion coefficient (ADC) values of these lesions...
