On fat-suppressed T1-weighted images after the administration of contrast-enhancing medium, enhancement of intratumoral lesions was evaluated in all cases.
Kinetic curve assessment should include initial peak enhancement (slow, medium, or rapid) and delayed-phase (persistent, plateau, or washout) analyses.
From these results, it can be seen that the use of low concentration of GNPs can achieve acceptable thermal conductivity enhancement for medium-temperature applications including solar collectors and heat exchanger systems.
The non-enhanced features described above, and the early enhancement after contrast medium injection with both CT and MRI are characteristics that can also be found in the presence of endocrine pancreatic tumors, while primary adenocarcinomas tend to be hypovascular [ 18].
The distribution of the contrast medium enhancement within the pancreatic lobe was evaluated subjectively as satisfactory or unsatisfactory, based on the degree of parenchymal enhancement and homogeneity at peak intensity (PI).
There was no enhancement after contrast medium injection on FS T1-WI.
The enhancement of the medium composition is therefore most likely independent from the employed producer strain.
The presence of vascularised granulation tissue, neovascularity in necrotic areas or reactive hyperaemia can cause gadolinium-based contrast medium enhancement.
Axial CECT image (e) shows the large, infiltrating left cervical muscular mass, with intense enhancement after contrast medium administration.
If the examination is performed to assess destructive bone changes such as erosions, then i.v. contrast medium enhancement is not mandatory.
It showed furthermore a clear contrast medium enhancement with a meningeal tail sign that was pathognomonic for meningiomas (see Fig. 1).
