On MR, SFT usually presents with intermediate intensity on T1-weighted image
and heterogenous hypointense on T2-weighted image, which is related to hypercellularity or collagen.
B) Axial gadolinium-enhanced T1-weighted image
shows enhancement within the cisternal segment of both the vestibulocochlear nerve complex and the facial nerve.
Figure 3(a) shows a comparison of textural features measured in VOI 1 in each T1-weighted image
in relation to those measured from the T1 map.
Abdominal magnetic resonance imaging (MRI) showed that the lesion is slightly hypointense on T1-weighted image
with the central scar appears more significant hypointense (Figure 3(a)) and slightly hyperintense on T2-weighted images (Figure 3(b)).
Caption: Figure 4: Sagittal T1-weighted image
(a) and sagittal postcontrast T1-weighted image
with fat suppression (b) show a significant tumor mass volume reduction after treatment.
(a) Plain axial T1-weighted image
of the abdomen revealed a mass in the right psoas muscle.
Capsular wall and internal septae of the lesion are isointense on T1-weighted image
and hypointense on T2-weighted image; marginally contrast enhancement seen on fat-saturated contrast enhanced T1-weighted image
The lesion was isointense relative to muscle on the T1-weighted image
and hyperin tense on the T2-weighted image with a swirled appearance [Figure 1].
A, Medial-most sagittal T1-weighted image
from the patient's MRI demonstrating significant fat within the supraspinatus and infraspinatus fossae.
There was also an axial-coronal T1-weighted image
with contrast showing enhancement of a nodular hyperintense active MS plaque in the left posterior limb of the internal capsule (Figure 2).
The selected images are images where the examination occurs during the relaxation took place, such as T1-weighted image
and T2-weighted image (Figure 2).
On the T1-weighted image
, the mass was of similar signal intensity to the adjacent muscles with an area of decreased signal intensity centrally and an area of slightly increased signal intensity peripherally.
