Introduction: Echoplanar diffusion-weighted images (EP-DWI) with breath holding (BH) have been widely applied to evaluate the apparent diffusion coefficient (ADC) of liver. Clinically, the spatial coverage of DWI is usually limited by the duration (around 20 seconds) of breath hold. Free breathing (FB) and respiratory gating (RG) methods allow larger spatial coverage of liver in one scan. Compa...

The MILC collaboration computation of heavy-light decay constants is described. Results for f B , f Bs , f D , f Ds and their ratios are presented. These results are still preliminary, but the analysis is close to being completed. Sources of systematic error, both within the quenched approximation and from quenching itself, are estimated, although the latter estimate is rather crude. ?0:01 , wh...

OBJECTIVE To investigate the value of 3-dimensional (3D) CT virtual anatomy imaging (VAI) in the complex foreign body (FB) retrieval of the soft tissues. MATERIALS AND METHODS Four hundred and seventy-five patients with radiopaque FB(s) diagnosed by radiograph underwent contrast-enhanced 3D CT examination. VAI was reconstructed by volume-rendering opacity software, by sliding down the lowest ...

An internal target volume (ITV) accounting for respiratory-induced tumor motion is best obtained using 4DCT. However, when 4DCT is not available, inspiratory/expiratory breath-hold (BH insp, BH exp) CT images have been suggested as an alternative. In such cases, an external fiducial on the abdomen can be used as a substitute for tumor motion and CT images are acquired when the marker position m...

Matrix metalloproteinase-2 (MMP-2) may play roles at intracellular and extracellular sites of the heart in ischaemia/reperfusion injury. Caveolins (Cav-1, -2 and -3) are lipid raft proteins which play roles in cell sig-nalling. This study examined, using immunohistochemistry and two photon confocal microscopy, if MMP-2 and caveolins co-localize at the plasma membrane of cardiac cells: cardiomyo...

STUDY OBJECTIVE To study the diagnostic role of flexible bronchoscopy (FB) in immunocompromised patients with pulmonary infiltrates. DESIGN Prospective, observational study. SETTING Tertiary care hospital. PATIENTS A total of 104 consecutive non-HIV-infected immunocompromised patients with lung infiltrates in whom FB was performed. METHODS The primary outcome measure was the diagnostic ...

The hybrid modular multilevel converter (HMMC) composed of half-bridge (HB) and full-bridge (FB) submodules (SMs) is an alternative to the FB-modular (MMC) with lower loss cost. However, HMMC's maximum reverse-biased voltage (RBV) than FB-MMC, so does dc fault clearing capability (DCFCC). Reduced RBV will prolong time, especially when side inductance large. In this letter, auxiliary circuit pro...

Most respondents state that Flow Based market coupling (FB) optimizes the allocation of cross-border capacity, which entails higher social welfare and higher price convergence. Better cooperation between TSOs is also mentioned, since FB forces TSOs and Exchanges to work together. According to most respondents FB will also lead to better transparency regarding critical branches and shadow prices...
