Figure 1.
A plot of the number of siderotic nodules detected by MRI in each patient.
The horizontal axis indicates the patient number, and the vertical axis indicates the number of siderotic nodules. Black rhombus, red squares, yellow triangles and blue star represent T1-weighted imaging, T2-weighted imaging, T2*-weighted imaging, and susceptibility-weighted imaging, respectively.
Figure 2.
Representative T1-weighted image (T1WI), T2-weighted image (T2WI), T2*-weighted image (T2*WI) and susceptibility-weighted imaging (SWI) of a 36 year-old patient with splenic siderotic nodules.
SWI shows a greater number of hypointense lesions (white arrows) with larger size and higher contrast than T1WI, T2WI or T2*WI.
Figure 3.
Representative T1-weighted image (T1WI), T2-weighted image (T2WI), T2*-weighted image (T2*WI) and susceptibility-weighted imaging (SWI) of a 42 year-old patient with splenic siderotic nodules.
SWI shows more siderotic nodules than T1WI, T2WI or T2*WI.
