Background Suppression of lipid signal is a basic requirement in coronary magnetic resonance angiography (CMRA) because coronary arteries are embedded in epicardial fat and signal from fat can decrease coronary vessel conspicuity. Most CMRA scans are currently performed with fat suppression techniques such as Spectral Presaturation with Inversion Recovery (SPIR). However, methods based on spect...

PURPOSE To determine the benefit of fat suppression in conjunction with gadolinium enhancement for evaluating neoplastic and inflammatory diseases of the spine. METHODS Contrast-enhanced T1-weighted images were compared with the corresponding contrast-enhanced T1-weighted images with fat suppression in 14 patients with various neoplastic and inflammatory spine diseases. RESULTS Contrast-enh...

(a) because of the variable level of fat suppression. Both 3DPR-SSFP with WC-SSFP (b) and IDEAL 3DPR-SSFP (c) provide a more consistent level of fat suppression allowing for better delineation of fine fibroglandular structure. IDEAL 3DPR-SSFP (c) also resolves fat-water swap due to B0 inhomogeneity in superior region of the breast. Red arrows: Note tiny gap in fibroglandular tissue in WC SSFP (...

around the perimeter of the body, not including fat signal (red). 2(b) Example b = 800 s mm images of each of the tested fat suppression combinations. Note the loss of water signal in some of the images acquired using SSGR as demonstrated by the white arrow. Note that due to time restrictions not all fat suppression techniques could be tested on the same volunteer. Combinatorial fat suppression...

UNLABELLED BACKGROUND; Previous studies reported the increased prevalence of cardiovascular disease (CVD) in patients with rheumatoid arthritis (RA) compared to the general population. However, the predictors for the development of CVD in patients with RA were not clearly established, and the role of thrombosis mechanisms was inconsistently characterized in these patients. The aim of this study...

Fat-suppression technology of magnetic resonance is very important in clinical practice. This article is written to interpret the principle, advantages/disadvantages and clinical applications of some regular fat-suppression sequences in the diagnosis of Bone-Joint Disease, including: 1) frequency-selective saturation (FS); 2) short-TI inversion recovery (STIR); 3) frequency selective inversion ...

BACKGROUND Mean platelet volume (MPV) and platelet distribution width (PDW) are indices that reflect platelet activity. We investigated the association between these platelet indices and left ventricular hypertrophy and cardiac function. METHODS We analyzed the data of 1241 patients who were admitted to the Cardiology Department. RESULTS Both MPV and PDW were selected as independent factors...

AIM Ventriculoperitoneal shunt infection (VPSI) is one of the main causes of mortality and morbidity in hydrocephalus. Platelet indices, mean platelet volume (MPV) and platelet distribution width (PDW) have been evaluated for some infectious diseases. In this study we aimed to investigate whether MPV and PDW values are decisive for the diagnosis of VPSI in children. MATERIAL AND METHODS Chart...

Introduction: Uniform fat signal suppression is often difficult to achieve in a 3.0 Tesla MR system due to magnetic field inhomogeneity and/or B1 inhomogeneity. DWIBS [1] has been proposed as a new method of diffusion MRI that suppresses background signal. In DWIBS, non-negligible fat signals often remain after fat suppression methods are used and the residual fat signals often considerably deg...

PURPOSE To develop a faster method of fat suppression for use in dynamic contrast enhanced MRI of the breast. MATERIALS AND METHODS A method of fast fat suppression is presented using spatially nonselective rapid binomial pulses. In contrast to conventional binomial frequency-selective pulses, these short pulses are applied without interpulse delay, allowing for very rapid spectrally selectiv...
