4D Flow MRI Velocity and Turbulence Mapping in Mild Valvular Heart Disease

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 1, Page 222-232, January 2026.
ABSTRACT Background Valvular heart disease (VHD) commonly leads to the development of turbulent blood flow. Turbulent kinetic energy (TKE), measured with 4D flow MRI, may be a complement to current metrics for early identification of VHD. Purpose To investigate TKE as a marker of VHD in relation to flow velocity and cardiovascular geometry.

Fetal Tricuspid Annular Plane Systolic Excursion in the Surveillance of Intra‐Abdominal Umbilical Vein Varix

open access: yesJournal of Ultrasound in Medicine, Volume 45, Issue 1, Page 51-58, January 2026.
Objective To describe the application of tricuspid annular plane systolic excursion (TAPSE) in monitoring cardiac function in cases of fetal intra‐abdominal umbilical vein varix (FIUVV). Methods The sample consisted of all cases of FIUVV diagnosed in a tertiary medical center between 2018 and 2023 that were assessed by sonographic fetal TAPSE.

Combining Detailed Fetal Anatomy Scanning in the NT Window Versus Early Second Trimester Scanning at 14–16 Weeks

open access: yesJournal of Ultrasound in Medicine, Volume 45, Issue 1, Page 105-113, January 2026.
Objectives First‐trimester ultrasound has evolved to incorporate a detailed fetal anatomy scan (FAS) with nuchal translucency (NT) screening. Many institutions use a 2‐visit protocol: NT followed by detailed FAS at 14–16 weeks. We aimed to evaluate whether integrating detailed FAS into the NT window (12 + 5 to 13 + 6 weeks) is non‐inferior in ...

Robust constrained weighted least squares for in vivo human cardiac diffusion kurtosis imaging

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 220-233, January 2026.
Abstract Purpose Cardiac diffusion tensor imaging (cDTI) can investigate the microstructure of heart tissue. At sufficiently high b‐values, additional information on microstructure can be observed, but the data require a representation such as diffusion kurtosis imaging (DKI).

Feasibility of tagged MRI at 0.55 T

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 465-473, January 2026.
Abstract Purpose To determine the feasibility of tagged MRI at 0.55 T and tag persistence for cardiac and speech production applications. This is particularly challenging due to the short muscle T1 at 0.55 T (701 ms) and requires advanced techniques for maximizing initial tag contrast and signal‐to‐noise ratio (SNR)–efficient imaging.
