Enhancement profiles of malignant lesion subgroups in MR- mammography: A computer assisted evaluation considering pharmacokinetic parameters

Magnetic Resonance Imaging Guided Vacuum Assisted and Core Needle Biopsies.

OBJECTIVE The purpose of this study to present the results of Magnetic resonance imaging (MRI) guided cutting needle biopsy procedures of suspicious breast lesions that can be solely detected on Magnetic resonance (MR) examination. MATERIALS AND METHODS The study included 48 patients with 48 lesions which were solely be observed in breast MRI, indistinguishable in ultrasonography and mammogra...

Small Lesions Evaluation Based on Unsupervised Cluster Analysis of Signal-Intensity Time Courses in Dynamic Breast MRI

An application of an unsupervised neural network-based computer-aided diagnosis (CAD) system is reported for the detection and characterization of small indeterminate breast lesions, average size 1.1 mm, in dynamic contrast-enhanced MRI. This system enables the extraction of spatial and temporal features of dynamic MRI data and additionally provides a segmentation with regard to identification ...

Multifarious Kinetic Analysis for Differentiation of Prostate Cancer and Benign Prostatic Hyperplasia in DCE-MRI

Prostate cancer (PC) and benign prostatic hyperplasia (BPH) are the most common diseases diagnosed in men, early and accurate differential diagnosis of which is an important task. DCE-MRI plays an essential role for cancer detection and characterization. Previous studies have tried to characterize time-enhancement curves of malignant and benign prostate tissues, and thereby to deduce the best d...

Evaluation of computer aided 3D parametric analysis of MR-mammography for follow-up assessment of malignant lesions under primary systemic therapy

Introduction: According to the annual statistics of the American Cancer Society, apart from non-melanoma skin cancer, breast cancer is currently the most common cancer type among women and the second most common cause of cancer death. In case of multricentric or inoperable tumor manifestation neoadjuvant chemotherapy is used for preoperative tumor size reduction. Hence, the assessment of early ...
