In a minority of patients, the two-hour scan showed gadolinium
in both eye chambers.
Nephrogenic systemic fibrosis (NSF) may develop in patients with renal failure on gadolinium
administration and may even be life-threatening.
In all cases, FLAIR T2 sequences without and with gadolinium
and FLAIR T1 sequence with gadolinium
On post gadolinium
T1W sequences, the lesion showed peripheral rim enhancement of the wall with central non-enhancing region suggestive of necrosis.
This might have resulted in the inclusion of gadolinium
exposures that were not related to the development of NFD.
Until more information becomes available, the association between gadolinium
contrast media and NSF should be kept in perspective, cautioned Dr.
MRI (T1 weighted) with gadolinium
contrast, however, reveals changes that can make a difference in the diagnosis of PDPH.
Instead of ozone-depleting refrigerants and energy-consuming compressors found in conventional vapor-cycle refrigerators, it uses gadolinium
metal that heats up when exposed to a magnetic field, then cools down when the magnetic field is removed.
But substituting potassium nitrate with gadolinium
nitrate had the same effect when one researcher tried to cleave a wafer with a diamond scribe.
He imposed a magnetic field on gadolinium
sulfate, then let it retreat into disorder on the removal of the field.
This study is of particular interest because Gadavist differs from other approved GBCAs in that it is formulated at double concentration (twice the concentration of gadolinium
is present per unit volume).
International medical imaging IT and cybersecurity company Sectra is globally introducing gadolinium
tracking in its dose monitoring solution, Sectra DoseTrack.
