Breast MRI enhancement curves Radiology Reference

DCE-MRI is routinely used to evaluate focal breast lesions. Adding information derived from kinetic curve type to architectural features of a lesion improves the specificity of breast MRI [ 3, 5, 6, 8, 12 ]. To our knowledge, prior studies have not compared quantitative kinetic curve type assessment with the standard qualitative method Typically breast MRI is performed on a 1.5 Tesla magnet with a dedicated multichannel breast coil. To detect abnormalities, achieving high spatial resolution and contrast is important. Scanning slice thickness should be 3 mm or less and resolution should be 1 mm or less in order to minimize volume averaging DCE MRI yields a time intensity curve (kinetic curve) that is commonly used in clinical settings. A key characteristic of the time intensity curve is the shape of the washout portion of the curve. The shape of DCE MRI curve is usually categorized as persistently enhancing (type I), plateau (type II), or washout (type III) (4) This study integrated a single-compartment kinetic model and dynamic contrast enhancement-magnetic resonance imaging to generate a kinetic modeling curve for improving the accuracy of diagnosis of breast lesions

American college of Radiology (ACR) Breast Imaging and Reporting Data System (BI-RADS) [5] describe the slope from pre-contrast phase to the initial enhancement phase, and the curve change in the delayed phases for kinetic curve assessment.

Interobserver agreement was analysed between the two reviewers Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has always been a problem solver in troublesome breast lesions. Despite its many advantages, the encountered low specificity results in unnecessary biopsies. Diffusion-weighted MRI (DW-MRI) is a well-established technique that helps in characterizing breast lesions according to their water diffusivity The purpose of this study is to analyze the magnetic resonance imaging (MRI) features of focal FCC of the breast.
