PET-CT. 11C-choline positron emission tomography of a patient with prostate cancer LN metastasis. (a) A positive signal is localized in the pelvis (white arrow). (b) A positive signal is located within a LN, increasing the specificity of the signal. Note the non-specific signals from the gut above the LN (red arrow). Therefore, CT enables the correlation of an anatomic structure like a LN or the gut to an 11C-choline positive signal. Image reproduced, with permission, from Ref. [6].
