Autor: Torill Eidhammer Sjøbakk, Hans E. Fjøsne, Tone Frost Bathen, Pål Erik Goa, Liv Egnell, Igor Vidic, Agnes Østlie, Neil P. Jerome

Publikováno v: NMR in biomedicineREFERENCES. 34(7)

Diffusion-weighted MRI (DWI) is an important tool for oncology research, with great clinical potential for the classification and monitoring of breast lesions. The utility of parameters derived from DWI, however, is influenced by specific analysis ch

A Simplified Approach to Measure the Effect of the Microvasculature in Diffusion-weighted MR Imaging Applied to Breast Tumors: Preliminary Results

Autor: Hans E. Fjøsne, Agnes Østlie, Tone Frost Bathen, Pål Erik Goa, Jose R. Teruel, Torill Eidhammer Sjøbakk

Publikováno v: Radiology. 281:373-381

Purpose To evaluate the relative change of the apparent diffusion coefficient (ADC) at low- and medium-b-value regimens as a surrogate marker of microcirculation, to study its correlation with dynamic contrast agent-enhanced (DCE) magnetic resonance

Publikováno v: Journal of Magnetic Resonance Imaging. 43:1111-1121

Background To compare “standard” diffusion weighted imaging, and diffusion tensor imaging (DTI) of 2nd and 4th-order for the differentiation of malignant and benign breast lesions. Methods Seventy-one patients were imaged at 3 Tesla with a 16-cha

Publikováno v: Acta Oncologica. 53:580-589

Magnetic resonance (MR) modalities are routine imaging tools in the diagnosis and management of gliomas. MR spectroscopic imaging (MRSI), which relies on the metabolic characteristics of tissues, has been developed to accelerate the understanding of
