Intravoxel Incoherent Motion Diffusion-Weighted Imaging of Prostate Cancer In this study, detailed diffusion measurements of normal prostate tissues, BPH, and prostate cancer using multiple b values have been made. Biexponential fits were applied to the diffusion decay curves to calculate the molecular diffusion OBJECTIVE. The purpose of this study is to investigate whether the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters are different between prostate cancer, benign prostatic hyperplasia (BPH), and healthy peripheral zone (PZ). To investigate the diagnostic value of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) for discriminating axillary metastatic from non-metastatic lymph nodes (LNs) in rabbit models.

All hidden states from the question and the context are used to calculate the Focal Visual-Text Attention (FVTA) tensor. Based on the FVTA attention, both  There are 69 malignant cases (including 9 early malignant cases) and 35 benign breast cases who underwent diffusion-weighted MRI at 3.0 T with 8 b-values (0  As an improved MRI technique, diffusion-weighted imaging (DWI) is considered the most sensitive for early pathological changes.

(6). This procedure can distinguish the incoherent motion of water molecules within the capillaries from molecular diffusion in the extravascular space (7).

Intravoxel incoherent motion diffusion-weighted imaging

To investigate the diagnostic value of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) for discriminating axillary metastatic from non-metastatic lymph nodes (LNs) in rabbit models. Intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI), with a bi-exponential model, can not only observe the diffusion of tissue water molecules but also reflect the blood perfusion information of tissue microcirculation, compensating for the deficiencies of conventional DWI. OBJECTIVE. The purpose of this study is to investigate whether the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters are different between prostate cancer, benign prostatic hyperplasia (BPH), and healthy peripheral zone (PZ).

Biexponential fits were applied to the diffusion decay curves to calculate the molecular diffusion Intravoxel incoherent motion (IVIM) imaging is a concept and a method initially introduced and developed by Le Bihan et al. to quantitatively assess all the microscopic translational motions that could contribute to the signal acquired with diffusion MRI. 2018-01-25 · Objective To evaluate intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) sequences for quantitative characterization of anal fistula activity. Methods This retrospective study was approved by the institutional review board. One hundred and two patients underwent MRI for clinical suspicion of anal fistula To compare the diagnostic performance of diffusion kurtosis imaging (DKI), intravoxel incoherent motion (IVIM), and monoexponential diffusion-weighted imaging (DWI) to detect clinically significant fibrosis (≥ F2). 2018-10-01 · Intravoxel incoherent motion diffusion-weighted imaging as an adjunct to dynamic contrast-enhanced MRI to improve accuracy of the differential diagnosis of benign and malignant breast lesions Intravoxel incoherent motion (IVIM) imaging enables the separate assessment of perfusion- and diffusion-related parameters, of which perfusion-related parameters may be helpful for differentiating pancreatic adenocarcinomas (PACs) from normal pancreas, chronic pancreatitis, and neuroendocrine tumors (NETs) (all P < .05).
