Accelerated Multi-b-Value DWI Using Deep Learning Reconstruction: Image Quality Improvement and Microvascular Invasion Prediction in BCLC Stage A Hepatocellular Carcinoma

Academic Radiology
To investigate the effect of accelerated deep-learning (DL) multi-b-value DWI (Mb-DWI) on acquisition time, image quality, and predictive ability of microvascular invasion (MVI) in BCLC stage A hepatocellular carcinoma (HCC), compared to standard Mb-DWI.Patients who underwent liver MRI were prospectively collected.

Early detection of global cerebral anoxia: improved accuracy by high-b-value diffusion-weighted imaging with long echo time.

AJNR. American journal of neuroradiology, 2005
Early and accurate detection of global cerebral anoxia is important for determination of prognosis and further management. We evaluated whether accuracy in early detection of global cerebral anoxia was improved by high-b-value diffusion-weighted imaging (DWI) with long echo time (TE).Routine DWI (b = 1000 s/mm(2); TE = 139 ms), high-b-value DWI (b ...

Integrated shimming technique can improve ultrahigh-b-value DWI in laryngeal and hypopharyngeal squamous cell carcinoma: comparison with conventional volume shimming

ISMRM Annual Meeting
This study aimed to investigate the value of integrated shimming (iShim) technique in the ultrahigh-b-value DWI images in laryngeal and hypopharyngeal squamous cell carcinoma (SCC) by comparing with the conventional volume shimming technique. Our results showed that the ultrahigh-b-value DWI images with iShim technique had significantly higher image ...

Can temporally and spatially varying b-values improve earthquake forecasts? Insights from a machine-learning-enhanced catalog in central Italy.

The b-value of the Gutenberg-Richter law is crucial for modern hazard models and seismicity forecasting. It quantifies the relative frequency of small earthquakes vs. infrequent large events. A growing number of studies suggest that the b-value changes with factors such as time (Gulia et al., 2018), differential stress (Scholz, 2015), and thermal ...

Improved visualization of high b-value prostate diffusion weighted imaging using LIPO-only multi-shot EPI with 2D navigator (LION-IRIS)

ISMRM Annual Meeting
Motivation: One of the drawbacks of IRIS is its low SNR compared with ss-DWI. High b-value DWI improves the ability of prostate cancer detection by increased cancer conspicuity. However, such high b value images may also suffer from decreased SNR. Goal(s): We hypothesized that using only slice selection gradient reversal (SSGR, LIPO) technique without ...
