Para-axial T1-weighted spin-echo MR images.

A, Five minutes after the first intravenous administration of an SD (0.1 mmol/kg) of the paramagnetic contrast agent, two enhancing lesions are visible: one in the right and the other in the left hemisphere (arrows).

B, Five minutes after the administration of a second SD of the paramagnetic contrast agent (for a total of 0.2 mmol/kg), the enhancement in these two lesions is more conspicuous (arrows). A third area of focal contrast enhancement is barely detectable in the frontal left lobe (arrowhead).

C, Five minutes after the administration of a third SD of the paramagnetic contrast agent (for a total of 0.3 mmol/kg), the enhancement in all the three lesions becomes more conspicuous so that even the small enhancement in the frontal left lobe can be detected with higher confidence.
