Contrast agents in radiology : Current agents approved, recommendations, and safety aspects.
[Contrast agents in radiology : Current agents approved, recommendations, and safety aspects.] Radiologe. 2013 Jan 24; Authors: Reimer P, Vosshenrich R Abstract The manuscript summarizes current approved contrast media and their indications. Contrast agents that are discussed include iodinated contrast agents, magnetic resonance (MR) contrast agents, and ultrasound contrast agents. Allergic and non-allergic renal adverse events are described. The clinical issue of metformin and the administration of contrast agents are updated. Nephrogenic systemic fibrosis (NSF) is discussed and safety issues of available MR contrast agents are analyzed. The most recent changes in European Society of Urogenital Radiology (ESUR) guidelines are also presented. PMID: 23340684 [PubMed - as supplied by publisher]

Juárez-Onofre, Francisco Rodríguez-Félix, E. Marquez-RiosAbstractGiant squid (Dosidicus gigas) proteins have appropriate functional properties, albeit of smaller magnitude in comparison to other marine species. Therefore, this research characterizes the ultrasound-induced (20 kHz; 20 and 40% amplitude; 0, 1, 3 and 5 min) changes to the physicochemical and foaming properties of mantl...
In this study, a method for measuring the degree of molecular orientation with longitudinal ultrasonic waves is proposed. Based on the ultrasonic-wave equation and linear superposition principle, the relationship between the ultrasound velocity and degree of orientation was established. Online and offline experiments were performed to validate the proposed method by measuring the degrees of orientation with dichromic Fourier transform infrared spectroscopy and two-dimensional wide-angle X-ray diffraction. The experimental results show a negative correlation between the ultrasound velocity and degree of orientation, which a...

The effects of different operating parameters of oxidation stage including residence time (2–24 min), formic acid to sulfur molar ratio (10–150), and oxidant to sulfur molar ratio (5–35) on the sulfur removal ...
ConclusionsFree hanging in a harness leads to rapid venous pooling in the lower limbs. The most important measure to prevent suspension syndrome might be constant movement of the legs.
ConclusionsIVUS is an effective diagnostic tool that displays high quality, real-time cross-sectional anatomy during venous interventions. When used as the sole intraoperative diagnostic modality, it seems to have a high clinical yield in patients in whom signs and symptoms of venous disease are severe enough to merit intervention.
ConclusionsPost-thrombotic changes might be reduced by lipid-lowering therapy.
ConclusionsThis novel percutaneous venous thrombectomy system is safe and effective for removing large volumes of lower extremity acute thrombus in a single session, without the need for lytic therapy, intensive care unit admission, or repeat intervention. Further studies are warranted to determine mid-term and long-term outcomes.
ConclusionsUGFS of the pathologic perforating vein at the time of RFA of saphenous vein reflux improved VLU healing. VLU recurrence was more frequent in patients with concomitant deep vein reflux. The authors suggest performing UGFS of the pathologic perforating vein at the time of RFA to improve VLU healing and monitoring of patients with associated deep vein reflux for ulcer recurrence.
ConclusionsBased on our experience, in-stent restenosis followed by inflow lesions in the common femoral vein are the most common causes of stent thrombosis. These data suggest a need for future research to target these areas.
