Effects of iodinated contrast and field strength on gadolinium enhancement: implications for direct MR arthrography.

PURPOSE To optimize direct magnetic resonance (MR) arthrography by determining the effect of dilution of gadolinium in iodinated contrast, saline, or albumin on T1-weighted, T2-weighted, and gradient-recalled echo (GRE) images, and the effect of scanner field strength. MATERIALS AND METHODS Gadopentetate dimeglumine was diluted into normal saline, albumin, or iodinated contrast (0.625 mmol/li...

Effects of adding local anesthetic and iodinated contrast agents to the paramagnetic contrast solution in direct MR arthrography

Radiol Bras. 2015 Mar/Abr;48(2):V–VI The introduction of hardware and software innovations have resulted in a huge advance for diagnostic imaging in the last decades, especially the evolution of functional studies of human tissues which do not require the use of contrast medium. Nevertheless, the use of contrast agents is still required in specific settings of the clinical practice to different...

Field-Strength Dependence of Gadolinium Enhancement: Theory and Implications

The decision to use contrast in magnetic resonance (MR) examination has important diagnostic , economic, and medicolegal implications. The overwhelming majority of published studies defining the clinical utility of gadolinium administration for neuroimaging have been performed at high fields (1-6) . Are these conclusions about contrast agent use at high fields equally valid for low-field imagin...

Effects of iodinated contrast agent, xylocaine and gadolinium concentration on the signal emitted in magnetic resonance arthrography: a samples study*

OBJECTIVE To investigate the effects of dilution of paramagnetic contrast agent with iodinated contrast and xylocaine on the signal intensity during magnetic resonance arthrography, and to improve the paramagnetic contrast agent concentration utilized in this imaging modality. MATERIALS AND METHODS Samples specially prepared for the study with three different concentrations of paramagnetic co...

Morbidity of direct MR arthrography.

OBJECTIVE The purpose of this study was to determine the incidence and severity of arthrographic pain after intraarticular injection of a gadolinium mixture diluted in normal saline for direct MR arthrography. SUBJECTS AND METHODS From March 2009 until January 2010, 155 consecutive patients underwent direct MR arthrography; 20 patients were lost to follow-up. Patients were contacted by teleph...
