 Lymph node metastasis of carcinoid has intense enhancement after contrast. The lymph node with intense enhancement is suspected as metastasis even if the diameter is less than 1 cm. The metastatic node shows low signal on T2-weighted MR image. Sometimes carcinoid has a mesenteric mass with irregular radiating linear opacities. Liver metastasis usually shows intense enhancement after contrast. Arterial phase study is essential for the diagnosis of liver metastasis. Delayed phase is also necessary for the diagnosis of hypovascular metastasis or differential diagnosis.
