Benign and Malignant Soft-Tissue Tumors: Posttreatment MR Imaging

Molecular markers in benign and malignant soft tissue tumors

Dynamic Contrast Magnetic Resonance Imaging (DCE-MRI) and Diffusion Weighted MR Imaging (DWI) for Differentiation between Benign and Malignant Salivary Gland Tumors

Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...

MR imaging differentiation of soft-tissue hemangiomas from malignant soft-tissue masses.

OBJECTIVE The purpose of this study was to determine whether MR imaging features can reliably distinguish hemangiomas from malignant soft-tissue masses. MATERIALS AND METHODS We retrospectively reviewed MR imaging studies of 22 patients with soft-tissue hemangiomas and 22 patients with malignant soft-tissue masses. Images were reviewed and agreement reached by a consensus interpretation of tw...

Differentiating benign and malignant soft tissue masses by magnetic resonance imaging: role of tissue component analysis.

BACKGROUND There is a variable degree of accuracy in discriminating benign from malignant soft tissue masses based on signal intensity and morphologic characteristics by magnetic resonance imaging (MRI). The aim of this study was to determine the utility of detailed component pattern assessment, in addition to morphologic study, for differentiating benign from malignant soft tissue masses by MR...

Frequency of Cytomegalovirus (CMV) in benign and malignant tumors

Cytomegalovirus (CMV) is a widespread pathogen that is found in milk, saliva, urine, cervical secretions, and semen fluid. It is supposed that CMV is a risk factor for breast cancer. The aim of this study was to determine the frequency of CMV among benign and malignant breast tumors. Paraffin embedded breast carcinoma (n=24) and fibroadenoma (n=24) samples were collected from Toos and Firoozgar...
