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

Journal of Ultrasound in Medicine, EarlyView.
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

Magnetic Resonance in Medicine, EarlyView.
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

Magnetic Resonance in Medicine, EarlyView.
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.

Altered sense of agency in schizophrenia: the aberrant effect of cardiac interoceptive signals

Frontiers in Psychiatry
BackgroundSchizophrenia (SZ) is characterized by abnormalities in self-representation, including a disturbed sense of agency (SoA). The continuous processing of sensory information concerning the internal state of the body (interoception) is argued to be

Comparison of cardiac diffusion MRI using multiple prospective respiratory motion correction techniques

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose A novel prospective motion correction control system with slice tracking (MNav‐CoS) was compared with three other prospective respiratory motion correction techniques in performing free‐breathing cardiovascular diffusion tensor imaging (cDTI) acquisitions. Methods Ten healthy volunteers underwent cDTI using an M2SE sequence.
