Motion-Compensated Multishot Pancreatic Diffusion-Weighted Imaging With Deep Learning-Based Denoising.
Invest Radiol
January 2025
From the Department of Radiology, Stanford University, Stanford, CA (K.W., M.J.M., A.M.L., A.B.S., A.J.H., D.B.E., R.L.B.); Department of Radiology and Biomedical Imaging, University of California, San Francisco, San Francisco, CA (K.W.); GE HealthCare, Houston, TX (X.W.); GE HealthCare, Boston, MA (A.G.); and GE HealthCare, Menlo Park, CA (P.L.).
Objectives: Pancreatic diffusion-weighted imaging (DWI) has numerous clinical applications, but conventional single-shot methods suffer from off resonance-induced artifacts like distortion and blurring while cardiovascular motion-induced phase inconsistency leads to quantitative errors and signal loss, limiting its utility. Multishot DWI (msDWI) offers reduced image distortion and blurring relative to single-shot methods but increases sensitivity to motion artifacts. Motion-compensated diffusion-encoding gradients (MCGs) reduce motion artifacts and could improve motion robustness of msDWI but come with the cost of extended echo time, further reducing signal.

Introduction: There is a growing emphasis on improving primary health care services and granting frontline service providers more decision-making autonomy. In October 2023, Kenya enacted legislation mandating nationwide facility autonomy. There is limited understanding of the effects of health facility autonomy on primary health care (PHC) facilities performance.

Background: Epilepsy is a neurological disorder affecting millions of people in Africa. Among other reported findings, many people living with epilepsy (PLWE) believe that the condition is caused by spiritual factors. Previous studies have revealed that majority of PLWE are not receiving adequate care and treatment because of diverse cultural beliefs associated with epilepsy.

Background: Explicit funding and industry affiliation are believed to potentially impact medical research. There have been an increasing number of studies that have evaluated this relationship. The purpose of this study is to determine whether industry affiliation influences the outcomes of randomized controlled trials that investigate the effectiveness of platelet-rich plasma (PRP) in the treatment of lateral epicondylitis.

Fibrosing mediastinitis is a rare chronic inflammatory condition characterized by excessive fibrotic process in the mediastinum. Although various infectious processes are more common causes, it can also be related to several malignancies. We report a case of a 28-year-old woman with fibrosing mediastinitis related to an aggressive primary gray-zone lymphoma causing complete occlusion of the superior vena cava (SVC) and the innominate veins.
