Background Fat-saturation and T1-weighting are fundamental for tissue differentiation, but combining these techniques is challenging. For instance, standard chemically selective saturation (CHESS) pulses provide insufficient fatsuppression with routine delayed enhancement imaging [1]. Fat-water separation using multi-echo Dixon techniques can robustly separate fat and water into individual imag...

Abstract Background As is well recognized that inflammation plays a crucial role in the genesis and progression of various cancer. Here we investigate prognostic value novel index: combination neutrophil to lymphocyte ratio platelet distribution width (coNLR-PDW) post-operation patients with resectable hepatocellular carcinoma (HCC). Methods The receiver operating characteristic (ROC) curve was...

Introduction: Linear filter-based Optimal Window Transition to Driven Equilibrium (LOW-TIDE) is a preparation scheme for T2 weighting and intrinsic fat suppression with balanced SSFP imaging when partial Fourier encoding in the phase direction is used [1]. Both TIDE [2] and LOW-TIDE use a (α/2)-(TR/2) preparation pulse followed by a train of π (180°) excitation pulses. This is followed by a smo...

OBJECTIVE To compare the quality of fat suppression and image quality between multiecho Dixon technique (mDixon) and spectrally adiabatic iversion recovery (SPAIR) in dynamic contrast-enhanced magnetic resonance imaging of the prostate. METHODS This prospective study assigned thirty consecutive patients to scanning with SPAIR technique (SPAIR protocol) and another consecutive 30 patients to s...

The purpose of this study was to compare the value of dynamic magnetic resonance imaging (MRI) and fat suppression in detecting a pancreatic tumor. The subjects were 19 patients with invasive ductal adenocarcinoma and six patients with islet cell tumor where diagnosis was established pathologically. Breath-hold gradient echo images, breath-hold gradient echo images with fat suppression and brea...

The passive dynamic walker (PDW) has an interesting characteristic that it realizes cyclic locomotion without planning joint trajectories. On the other hand, the walking behavior cannot be controlled because it is dominated by the fixed body dynamics. Observing the human cyclic locomotion that is activated by elastic muscles, we adopt a compliant hip joint on PDW, and we propose the ”phasic dyn...

Background Late Gadolinium Enhancement (LGE) allows imaging of infarction by visualizing the accumulation of contrast agent within the myocardium using an inversion recovery (IR) prepared sequence. However, myocardial hyperenhancement can sometimes be poorly detected in the vicinity of epicardial fat because both fat and hyperenhanced tissue appear bright. Thus, a method for fat signal suppress...

Balanced steady-state free precession (SSFP) is hindered by the inherent off-resonance sensitivity and unwanted bright fat signal. Multiple-acquisition SSFP combination methods, where multiple datasets with different fixed RF phase increments are acquired, have been used for shaping the SSFP spectrum to solve both problems. We present a new combination method (weighted-combination SSFP or WC-SS...

We show a detailed magnetic resonance (MR) examination of two rare pericallosa lipomas with a fat suppression imaging sequence and proton MR spectroscopy. For comparison, subcutaneous fat and lipids in glioblastomas were examined with H MR spectroscopy in vivo and ex vivo. Fat suppression makes the identification of lipomas simple. It is suggested that H MR spectroscopy shows no differences in ...
