Whole-body diffusion-weighted imaging in lymphoma

The current evidence regarding the usefulness of whole-body diffusion-weighted magnetic resonance imaging (DWI) in lymphoma is reviewed. DWI is capable of combining anatomical and functional information and is becoming a valuable tool in oncology, in particular for staging purposes. DWI may prove to be a useful biomarker in clinical decision making for patients with lymphoma. Large-scaled prosp...

Diffusion Kurtosis Imaging in Prostate Cancer

Introduction: Diffusion weighted imaging (DWI) and the calculated apparent diffusion coefficient (ADC) is showing potential for improving detection of prostate cancer (PCa), as the increased cellularity of many tumors is associated with restricted water diffusion and thus with a decreased ADC [1,2]. The ADC assumes Gaussian water diffusion and is calculated by monoexponential fitting. However, ...

Whole-body-MR-diffusion weighted imaging in oncology.

UNLABELLED The clinical implementation of whole body diffusion weighted imaging (WB-DWI) for tumor-detection, -characterization and therapy monitoring is well underway. The method is fast, robust and combined with its wide availability on modern MRI scanners, it has a vast potential clinical impact. Owing to the high tumor to background contrast, its main application areas are simple detection ...

Whole-Body Diffusion Imaging Applying Simultaneous Multi-Slice Excitation.

PURPOSE The purpose of this study was to examine the feasibility of a fast protocol for whole-body diffusion-weighted imaging (WB-DWI) using a slice-accelerated echo-planar sequence, which, when using comparable image acquisition parameters, noticeably reduces measurement time compared to a conventional WB-DWI protocol. MATERIALS AND METHODS A single-shot echo-planar imaging sequence capable ...

Constrained diffusion kurtosis imaging using ternary quartics & MLE.

PURPOSE Diffusion kurtosis imaging (DKI) is a recent improvement over diffusion tensor imaging that characterizes tissue by quantifying non-gaussian diffusion using a 3D fourth-order kurtosis tensor. DKI needs to consider three constraints to be physically relevant. Further, it can be improved by considering the Rician signal noise model. A DKI estimation method is proposed that considers all t...
