With a biphasic injection protocol, enhancement of the aorta and left ventricle was weaker with the higher concentration of contrast material.
An elaborate MR examination can identify patients with CP. Velocity-encoded flow measurements with calculation of transtricuspid e- to a-wave ratios are a valuable tool for detection of diastolic dysfunction in patients with CP. The value of e- to a-wave ratios may indicate elevated RVEDP.
Cardiac MDCT allows the differentiation between functional and valvular causes of MR.
It is feasible to evaluate skeletal muscle via 3D 23 Na MRI at 7 T. Post-exercise muscle 1 H T 2 values return to baseline more rapidly than sodium SI. Diabetics may demonstrate delayed muscle sodium SI recovery compared with healthy subjects.
Correction of both recovery and motion blur is mandatory for accurate SUV quantification of SPNs.
These preliminary findings suggest that qualitative real-time ultrasound elastography, although an ancillary technique to conventional ultrasound in the salivary glands, is likely to have a poor ability to discriminate benign lesions (particularly PAs) from malignant disease.
Real-time CEUS-guided biopsy is technically feasible for hepatic focal lesions that are not confidently localised on B-mode US.
The copolymer seems to have great potential in embolotherapy of acute arterial gastrointestinal bleeding. In our series none of the patients had rebleeding at the site of embolisation and no clinically obvious bowel necrosis occurred.
MR first-pass perfusion can rapidly estimate regional MBF and MBV. Absolute quantification of MBV may add additional information on stenosis severity and myocardial viability compared with standard qualitative clinical evaluations of myocardial perfusion.
