MRI revealed a heterogeneous T1-weighted signal, and a hyperintensity mixed with hypointensity signal on T2-weighted images.
Multi-parametric MRI (mp-MRI) includes combination of high-resolution T2-weighted images assessing the anatomy and at least two functional MRI techniques, i.
On fat-suppressed T2-weighted images, fluid, pus, and granulation tissue are seen as areas of high signal intensity on a background of low-signal-intensity fat.
Non-mineralized lesions tend to form an intraarticular mass that is isointense to muscle on T1-weighted images and hyperintense on T2-weighted images.
Superficial endometriotic lesions and endometrioma appear hyperintense on T1-weighted images when recent, or hypointense on T1-weighted images and heterogeneously hyperintense on T2-weighted images when old; however, superficial implants are rarely seen on MRI.
Magnetic resonance imaging (MRI) revealed a well-defined and lobulated mass in the scalene muscles with a hypointense signal void on T1-weighted images (Figure 2a) and a hyperintense signal void on T2-weighted images (Figure 2b), and it showed extensive enhancement on gadolinium-enhanced T1-weighted images.
The mass was hypointense on T1-weighted images, and hyperintense with central cystic component on T2-weighted and fat-saturated T2-weighted images (Figure 1).
MRI revealed a well-defined popliteal mass with low signal intensity on T1-weighted images and heterogeneous intermediate signal intensity on T2-weighted images (Figures 1(a) and 1(b)).
Axial brain MRI revealed symmetric edema in the bilateral basal ganglia, which exhibited hypointensity on T1-weighted images (Figure 1(a)) and hyperintensity on both T2-weighted images (Figure 1(b)) and fluid-attenuated inversion recovery (FLAIR) images (Figure 1(c)).
With T2-weighted images, the tumor is homogenous in signal intensity, with cystic or degenerative changes.
Areas of high signal on T1-weighted images and low or heterogeneous signal intensity on T2-weighted images can help identify blood products indicative of previous hemorrhage within the tumor.
Axial T2-weighted images with fluid attenuated inversion recovery (FLAIR) at the level of the basal ganglia showed an increased signal of the fornix and periventricular region around the third ventricle and the medial thalamic nuclei.
