The role of computed tomography and other imaging modalities in malignant lymphoma.

SUMMARY 
 
In view of the critical value of the staging of malignant lymphomas, accurate imaging of disease extent is of great importance. This accuracy can be achieved using CT scanning as the primary imaging modality, supplemented by additional imaging tests as necessary. LAG is advised only if the CT scan of the abdomen is normal. US is not recommended for routine staging because of the serious technical limitations imposed by bowel gas, especially in the pelvis. Gallium 67 citrate scanning may be useful in monitoring disease progress but its value here is not clearly defined. This area of residual disease activity may prove to be better assessed by aspiration biopsy23-24.
