Evaluation of recurrence in gastric carcinoma: Comparison of contrast-enhanced computed tomography and positron emission tomography/computed tomography

Figure 4 Lymph node recurrence detected on both contrast-enhanced computed tomography and positron emission tomography/computed tomography in a 73-year-old man who underwent gastrectomy 18 mo prior. A: Contrast-enhanced abdominal computed tomography shows enlarged lymph nodes at the aortocaval and para-aortic spaces; B: Positron emission tomography/computed tomography image at the same level shows hypermetabolism at the aortocaval and para-aortic spaces.
