Eleven patients with known or suspected optic nerve lesions and eight normal subjects were examined with spin-echo technique at 1.5 T with unenhanced T1-weighted imaging, IV gadopentetate-dimeglumine-enhanced T1-weighted imaging, and enhanced T1-weighted imaging with fat suppression. Two pathologically proved and four presumed optic nerve meningiomas demonstrated significant enhancement and wer...

BACKGROUND The extent of acute aortic dissection (AAD) was correlated with inflammation positively. On the other side, inflammation was negatively correlated with mean platelet volume (MPV), which can reflect platelet (PLT) activation. The aim of this study was to clarify the relationship between the extent of dissection and PLT activation. METHODS Between February 2010 and October 2013, 147 ...

Introduction: Breast MRI is a highly sensitive imaging tool for the diagnosis and staging of breast cancers. High spatial resolution is a requirement to ensure accurate lesion evaluation, along with fat suppression for assessment of lesion morphology and margins. Active fat suppression such as by chemical shift selective saturation requires homogeneous magnetic field across the entire field-of-...

BACKGROUND Because protons in fat do not exhibit a temperature-dependent frequency shift, proton resonance frequency shift (PRFS)-based MR thermometry always suffers from disturbances due to the presence of fats or lipids. OBJECTIVE A new fat suppression method for PRFS-based MR thermometry is proposed to obtain accurate variation of phase angle. METHODS Similar to the approach of separatin...

A 42-year-old male presented for evaluation of palpitations and chest pain. Physical examination suggested mild mitral regurgitation. Initial echocardiography showed a large mass attached to the interatrial septum. He then underwent cardiac magnetic resonance imaging for tissue characterization of the mass. Spin-echo imaging without (Figure, A) and with (Figure, B) inversion-recovery fat suppre...

The design and development processes of complex technical systems are important to the competitiveness of enterprises. These processes are characterised by high creativity and strong non-deterministic dynamics spanning different disciplines, relying on cooperation of different organisations. To successfully support these cooperative activities, methods of experience management are needed. This ...

To provide additional support to the hypothesis that only dietary protein (Pro; chicken egg albumin) and not amino acids (AA; patterned after albumin), carbohydrates (CHO; cornstarch), or fats (Fat; corn oil) produces a satiating effect via CCK receptors, two CCK-A receptor antagonists (PD-140,548 and devazepide) were coadministered with each nutrient. Given alone [4 ml intragastrically (ig)] P...

The purpose of this study was to determine whether delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) and T2 mapping are accurate techniques for measuring cartilage thickness in the metacarpus3/metatarsus3 (Mc3/Mt3) of Thoroughbred racehorses. Twenty-four Mc3/Mt3 cadaver specimens were acquired from six healthy racehorses. Cartilage thickness was measured from postint...

Background: Several studies reported the role platelet activation, volume (MPV) and other Indices in breast cancer but data is inconsistent and/or diverse. The aim of this study was to systematically evaluate activation indices women with BC as predictors for progression poor prognosis. Methods: Patients were recruited from our local oncology center between 2019 2020 following ethics approval. ...

OBJECTIVE. The purpose of this study is to evaluate whether the application of spectral pre-saturation inversion recovery (SPIR) fat suppression in standard multiecho gradient-echo sequences has a significant effect on hepatic R2* quantitation in patients with iron overload syndromes. MATERIALS AND METHODS. Eighty patients were scanned with a multiecho gradient-echo sequence without and with th...
