Comparative StudyDynamic MRI, dynamic multidetector-row computed tomography (MDCT), and coregistered 2-[fluorine-18]-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET)/CT: comparative study of capability for management of pulmonary nodules.
To compare the nodule management capabilities of dynamic MRI, dynamic multidetector-row computed tomography (MDCT) and coregistered positron emission tomography (PET)/CT. ⋯ Dynamic MRI can play a more specific and/or accurate role for nodule management as compared with dynamic MDCT and coregistered PET/CT.

Clinical TrialContrast-enhanced timing robust acquisition order with a preparation of the longitudinal signal component (CENTRA plus) for 3D contrast-enhanced abdominal imaging.
To investigate a new image acquisition method that enables an accurate hepatic arterial phase definition and the visualization of contrast agent uptake processes in abdominal organs like liver, spleen, and pancreas. ⋯ The elliptical centric nature of the new image acquisition method effectively allows capture of the contrast enhancement processes with good fat suppression.

Comparative StudyTumor-liver contrast and subjective tumor conspicuity of respiratory-triggered T2-weighted fast spin-echo sequence compared with T2*-weighted gradient recalled-echo sequence for ferucarbotran-enhanced magnetic resonance imaging of hepatic malignant tumors.
To compare respiratory-triggered T2-weighted fast spin-echo (RTT2W-FSE) and gradient T2*-weighted recalled-echo (T2*W-GRE) images for visualization of malignant hepatic tumors using ferucarbotran-enhanced magnetic resonance (MR) imaging. ⋯ For ferucarbotran-enhanced MR imaging, compared to FSPGR images, RTT2W-FSE images provide greater TLC and subjective conspicuity for malignant tumors.

3D dynamic contrast-enhanced MRI of rectal carcinoma at 3T: correlation with microvascular density and vascular endothelial growth factor markers of tumor angiogenesis.
To determine how dynamic contrast-enhanced (DCE) MRI at 3T correlates with rectal carcinoma angiogenesis. ⋯ DCE MRI parameters help predict rectal tumor angiogenesis measured by MVD and VEGF expression and discriminate malignant from normal tissue.

Clinical Trial4D time-resolved MR angiography with keyhole (4D-TRAK): more than 60 times accelerated MRA using a combination of CENTRA, keyhole, and SENSE at 3.0T.
To present a new 4D method that is designed to provide high spatial resolution MR angiograms at subsecond temporal resolution by combining different techniques of view sharing with parallel imaging at 3.0T. ⋯ 4D time-resolved MRA with keyhole (4D-TRAK) is feasible using a combination of CENTRA, keyhole, and SENSE at 3.0T and allows for more than 60 times accelerated MRA with high spatial resolution.
