Figure 2 demonstrates the signal intensity of Gadovist[R] and [Gd.sub.n.sup.3+]@CNTs-PEG with the same protocol and a similar percentage concentrations (100%, 50.0%, 25.0%, 12.5%, and 6.3%).
Signal intensity ratio = ([SI.sub.tumor]/[SI.sub.ipsilateral kidney]) x 100
Cholesterol granulomas classically have high signal intensity on both T1- and T2-weighted MR sequences due to accumulation of blood products and proteinaceous debris (Figure 6).
For calculating the volume of post-exercise intramuscular edema in the MGM, the expected post-exercise T2-weighted TIRM signal intensities of the MGM were calculated using the rule of three [expected signal intensity post-exercise MGM = (signal intensity pre-exercise MGM x signal intensity of agarose post-exercise)/signal intensity of agarose pre-exercise].
* Grade II--Tendinosis/tendinitis--Increased signal intensity on T2WI that does not involve inferior (articular) or superior (bursal) surface.
(10) On MRI, the lesion appears as a cluster of small cysts, usually demonstrating simple fluid signal intensity, though occasionally showing T1-hyperintensity if there is hemorrhage.
There are also some variations in the venous sinuses signal intensity due to slow flow of blood that appears as high signal intensity on conventional MRI.18-20 The stagnant blood typically appears iso-intense on T1 and hyper-intense on T2-weighted images.
T2 Fluid Attenuated Inversion Recovery (FLAIR) Imaging Study of Brain MRI showed Right Thalamic High Signal Intensity
As the distance to the object increases, the conventional ToF sensor has a walk error due to change of the signal intensity. The proposed technique reduces the walk error by detecting the center point between the rising point and falling point of the received signal.
Confocal microscopy revealed an increase of LDs after oligomycin treatment in all cell lines even if at different extent (Figures 5 and 6(a)) that matched ML signal intensity variations in MR spectra (Figures 5 and 6(b)).
Caption: Figure 1: (a) T1 coronal magnetic resonance image showing nodular intra-articular mass with low signal intensity (arrow).
On the opposed-phase image, hyperplasia presents a signal intensity decrease, whereas the thymic tumor does not.
