Figure 4
Lymph node evaluation depicted in 68Gallium-Prostate specific membrane antigen PET-CT and multiparametric MRI. This figure shows an example of lymph node (LN) detection using multiparametric MRI. The lymph node is visualized in corresponding axial plane slices using 68Gallium-Prostate specific membrane antigen PET-CT, T1 and T2 sequences of MRI presented left to right. The additional use of the T2 weighted sequence improved the detection of a LN in risk to be missed. This suspect LN is located at the right external iliac artery and is challenging to depict in the T1 sequence. (A) Lymph node depicted in 68Gallium-Prostate specific membrane antigen PET-CT, (B) Lymph node depicted in the T1 sequence in MRI; (C) Lymph node depicted in the T2 sequence in MRI.
