Application of Contrast-Enhanced Ultrasound (CEUS) in Lymphomatous Lymph Nodes: A Comparison between PET/CT and Contrast-Enhanced CT

Table 1

Criteria of the imaging method including CEUS, contrast-enhanced CT, and PET/CT to diagnose the malignant lymphomatous nodes.

Imaging modalities	Criteria for diagnosis of lymphomatous lymph nodes
CEUS	Rapid well-distributed hyperenhancement lymph nodes; Rapid heterogeneous hyperenhancement lymph nodes
PET/CT	Positive lesion shown as focal or diffuse FDG uptake above background in a location incompatible with normal anatomy or physiology without a specific SUV cutoff; SUVmax > 14 informs the lymph nodes had transformed, whereas those with SUVmax < 14 do not
Contrast-enhanced CT	Maximum diameter is ≥10 mm, and minimum diameter is ≥6 mm; Central area of neuroses; Margins are blurred; The target metastasis lymph nodes have special reinforcement
