Introduction Robust fat suppression is crucial for accurate evaluation of T2-weighted, post-contrast T1-weighted, and diffusion-weighted images. Nowadays, fat suppression is satisfactory in most of the cases. However, susceptibility induced field inhomogeneities as well as B1 inhomogeneity increases substantially with increasing field strength, which makes homogeneous fat suppression challengin...

Q. Peng, R. W. McColl, P. T. Weatherall Radiology, UT Health Science Center at San Antonio, San Antonio, TX, United States, Radiology, UT Southwestern Medical Center, Dallas, TX, United States INTRODUCTION Fat suppression is an important MRI procedure widely employed in many research and clinical applications. Fat suppression reduces chemical shift artifacts, enhances lesion conspicuity, and im...

We show that the pair-density-wave (PDW) superconducting state emergent in extended Heisenberg-Hubbard models in two-leg ladders is topological in the presence of an Ising spin symmetry and supports a Majorana zero mode (MZM) at an open boundary and at a junction with a uniform d-wave one-dimensional superconductor. Similarly to a conventional finite-momentum paired state, the order parameter o...

OBJECTIVE A retrospective study to determine the relationships between platelet parameters and inflammation and fibrosis of the liver in patients with chronic hepatitis B virus infection (CHB). METHODS Patients with liver biopsy-confirmed CHB were included in the study. Liver fibrosis and inflammation were assessed by histopathology of biopsied liver tissue. Platelet count (PLT), platelet dis...

Here, we explore the sensitivity of different awareness scales in revealing conscious reports on visual emotion perception. Participants were exposed to a backward masking task involving fearful faces and asked to rate their conscious awareness in perceiving emotion in facial expression using three different subjective measures: confidence ratings (CRs), with the conventional taxonomy of certai...

Background Sufficient peri-vascular fat suppression is critical for the outer wall boundary delineation in vessel wall imaging. The MSDE technique has been shown to significantly improve the blood suppression efficiency and measurement reproducibility. A limitation is that, due to the uncompensated eddy currents, undesired frequency shift can be observed after the MSDE prepulse, making the spec...

Pak J Med Sci 2015 Vol. 31 No. 3 www.pjms.com.pk 745 We read with great interest the article “Can mean platelet volume and platelet distrubition width be possible markers for ectopic pregnancy and tubal rupture?” by Ulkumen et al. in Pakistan Journal of Medical Sciences.1 We appreciate the authors for their study. We wanted to contribute to this study as it was related to our article: “The effi...

BACKGROUND Subjects with high fibroblast growth factor 21(FGF21) and 23 (FGF23), endocrine hormones that regulate insulin sensitivity and phosphate metabolism, respectively, are reported to have a higher risk for adverse cardiovascular outcome. Therefore, the relationship of FGF21, FGF23, and α-Klotho (co-receptor for FGF23 signaling) with mean platelet volume (MPV) and platelet distribution wi...

PURPOSE To evaluate and quantify improvements in the quality of fat suppression for fast spin-echo imaging of the knee using multipeak fat spectral modeling and IDEAL fat-water separation. MATERIALS AND METHODS T(1)-weighted and T(2)-weighted fast spin-echo sequences with IDEAL fat-water separation and two frequency-selective fat-saturation methods (fat-selective saturation and fat-selective ...

The effect of fat suppression on orbital MR imaging was tested by using a derivative of the Dixon method called chopper fat suppression in eight normal volunteers and eight patients with normal conventional orbital MR studies. Chopper fat suppression requires no postacquisition image processing or increased scan time and can be applied through a wide range of n to T2 weighting. In normal orbits...
