Accuracy of positron emission tomography in staging patients with malignant melanoma

FDG–PET sensitivity for melanoma lymph node metastases is dependent on tumor volume

“…FDG± PET detection of metastatic tumor also appears to be modulated by the location of the tumor and by the background glucose utilization in various organ systems. Prior reports have variously noted high sensitivity for detection of lymph node metastases while liver or lung metastases may not be detected with higher sensitivity than with conventional imaging [1,4,14]. Scanning system resolution may also impact upon sensitivity.…”
