Short name: SHU 555 A, generic name: Ferucarbotran
A RES-directed MRI contrast agent (SPIO) made-up of a colloidal sol of iron oxide nanoparticles coated with carboxydextran (Resovist®, Cliavist™).
It is used for the detection and characterization of especially small focal liver lesions and offers the opportunity to make a reliable diagnosis at a very early stage of patients with suspected liver tumors.
Bayer Schering Pharma AG announced that it has received marketing approval for the liver-specific contrast agent Resovist® in Japan. See Contrast Agents and Superparamagnetic Contrast Agents.

Bolus Tracking
 
A method of tracking moving spins after tagging them (locally altering their magnetization). The moving spins are then imaged at some time after tagging to show where the bolus (the small tagged volume of spins) has moved in the imaging plane.

MRI Safety Guidance
Occult incorporated ferromagnetic foreign bodies are dangerous, in particular those close to the eyes. The patient's history may help because many patients do not remember such accidents. In case of doubt, X-rays should be taken prior to MR imaging.

Bolus Injection
 
A bolus is a rapid infusion of high dose contrast agent. Dynamic and accumulation phase imaging can be performed after bolus injection. Since the transit time of the bolus through the tissue is only a few seconds, high temporal resolution imaging can be required to obtain sequential images during the wash in and wash out of the contrast material and, therefore, resolve the first pass of the tracer.
For the same injected dose of contrast agent the injection rate (and, consequently, the total injected volume) modifies the bolus peak profile. Increasing the injection rate produces a sharpening of the peak (Cmax increase, Tmax decrease, peak length decrease). At a low injection rate, the first pass presents a plateau form. Substantial changes in the gadolinium concentrations during signal acquisition induce artifacts. Furthermore, the haemodynamic parameters (cardiac output, blood pressure) influence the bolus profile. The characteristics of gadolinium agents are favorable in the early bolus phase, whereas the advantages of large complexes (e.g. blood pool agents) and ultrasmall superparamagnetic iron oxide (USPIO) are most evident in the distribution phase.
