Computed tomography enhancement characteristics of lymphomatous lymph nodes of the neck.
OBJECTIVE
The objective of this study was to investigate prospectively CT contrast medium enhancement curves of lymphomatous lymph nodes of the neck.


METHODS
Eleven patients with biopsy-proven lymphoma had their enlarged cervical lymph nodes examined with dynamic CT and compared with a control group.


RESULTS
The mean contrast medium enhancement of the lymphomatous nodes was significantly lower than that of the control group in the time interval from 40 s to 180 s after injection.


CONCLUSIONS
The enhancement pattern previously suggested from studies of retroperitoneal lymph nodes was confirmed in this prospective study of cervical nodes.
