Diffusion-weighted imaging of bone marrow.
In diffusion-weighted magnetic resonance imaging (DWI-MRI), the observed MRI signal intensity is attenuated by the self-diffusion of water molecules. DWI can provide information about the microscopic structure and organization of biological tissue and thus can depict various pathological changes of organs or tissues. DWI has been successfully used for the characterization of bone marrow alterat...
متن کاملDiffusion imaging of the vertebral bone marrow.
Diffusion-weighted MRI (DWI) of the vertebral bone marrow is a clinically important tool for the characterization of bone-marrow pathologies and, in particular, for the differentiation of benign (osteoporotic) and malignant vertebral compression fractures. DWI of the vertebral bone marrow is, however, complicated by some unique MR and tissue properties of vertebral bone marrow. Due to both the ...
متن کاملSpectrally-Selective IR Diffusion-Weighted Imaging with SSFP of Bone Marrow at 3T
Introduction The use of diffusion-weighted (DW) imaging with steady-state free precession (SSFP) for the diagnosis of bone marrow has been reported (1-2). One notable limitation of this approach is the contribution of fat (lipid) signal intensity within bone marrow to the DW signal (3, 4). Healthy bone marrow contains substantial amounts of lipids (20-70%). The lipid component is reduced in pat...
متن کاملDiffusion-Weighted Magnetic Resonance Imaging as a Potential Tool in Differentiation of Vertebral Bone Marrow Lesions
Background: Pathological lesions usually replace normal components of the vertebral bone marrow including benign and malignant lesions, as well as, fractures, inflammatory and degenerative marrow process. DWI is considered to be a potential tool which can help in characterization of different bone marrow lesions by exploiting the structural differences of biologic tissue. Objective: To evaluate...
متن کاملDiffusion-Weighted Imaging with Sensitivity Encoding (SENSE) for Detecting Cranial Bone Marrow Metastases: Comparison with T1-Weighted Images
OBJECTIVE This study was designed to determine whether diffusion-weighted imaging (DWI) with sensitivity encoding (SENSE) could detect bone marrow involvement in patients with cranial bone marrow (CBM) metastases. DWI results obtained were compared with T1-weighted imaging (T1WI) findings. MATERIALS AND METHODS DWI with sensitivity encoding (SENSE; b value = 1,000) was performed consecutively...
