Diagonal DWI : A Time‐Efficient Alternative to 3‐Scan Trace DWI for Breast Lesion Evaluation at 3.0‐T MRI —A Phantom Study and Clinical Assessment

Yusuke Jo, Yuki Sato, Mami Iima, Hiroko Satake et autres

BACKGROUND: Diffusion-weighted imaging (DWI) in breast MRI requires balancing image quality with acquisition time. Reducing scan time without sacrificing diagnostic performance could improve patient comfort and workflow. PURPOSE: To compare 3-scan trace DWI (tDWI) and diagonal DWI (dDWI) for breast lesion evaluation …

Diagonal DWI: A Time-efficient Alternative to 3-scan Trace DWI for Breast Lesion Evaluation at 3.0T - Phantom Study and Clinical Assessment

Yusuke Jo, Mami Iima, Yutaka Kato, Hiroko Satake et autres

Motivation: Diffusion-weighted imaging (DWI) optimization in breast MRI protocols faces challenges between image quality and acquisition efficiency. Diagonal DWI (dDWI) potentially offers advantages over traditional 3-scan trace DWI (tDWI). Goal(s): Compare traditional tDWI and dDWI for breast lesion evaluation at 3.0T MRI, …

Evaluation of 4D Flow MRI‐Derived Relative Residence Time as a Marker for Cirrhosis Associated Portal Vein Thrombosis

Ryota Hyodo, Yasuo Takehara, Yoji Ishizu, Kazuki Nishida et autres

BACKGROUND: Portal vein thrombosis (PVT) is thought to arise from stagnant blood flow, yet conclusive evidence is lacking. Relative residence time (RRT) assessed using 4D Flow MRI may offer insight into portal flow stagnation. PURPOSE: To explore the relationship between RRT values …

Four-dimensional Flow MRI Assessment of Portal Hemodynamics and Hepatic Regeneration after Portal Vein Embolization

Ryota Hyodo, Yasuo Takehara, Takashi Mizuno, Kazushige Ichikawa et autres

Background Percutaneous transhepatic portal vein (PV) embolization (PVE) is a standard preoperative procedure for advanced biliary cancer when the future liver remnant (FLR) is insufficient, yet the effect of this procedure on portal hemodynamics is still unclear. Purpose To assess whether four-dimensional …

Assessment of myocardial involvement in patients with Fabry disease using metabolic imaging by 1H-MR Spectroscopy (1H-MRS)

Masaru Shiotani, Yoshiaki Morita, Yoshito Ichiba, Yasuhiro Nagai et autres

The peak ratio of 3.5ppm to water in 1H-MRS of myocardium showed the higher values in Fabry disease and the association with native T1 values and regional function. 1H-MRS has a potential as disease-specific imaging biomarker for direct quantification of myocardial sphingolipid …

Image Quality of Submillimeter High-Spatial-Resolution 2D Late Gadolinium-enhanced Images in Cardiac MRI: A Feasibility Study

Yasutoshi Ohta, Tatsuya Nishii, Yasuhiro Nagai, Yoshito Ichiba et autres

Purpose To evaluate the image quality of high-spatial-resolution two-dimensional (2D) late gadolinium enhancement (LGE) cardiac MRI compared with conventional normal-resolution LGE MRI. Materials and Methods This prospective study included participants suspected of having cardiomyopathy who underwent cardiac MRI between March 2021 and …
