non Hodgkin’s Lymphoma
Malignancy of lymph cells of the spleen , GI stsyem
CT
Malignancy of lymphoid cells in the lymph node, bone marrow, spleen, liver and GI system
Exam to diagnose
Non-hodgkin’s lymphoma
Ct
what is the difference between NHL and
Hodgkin’s lymphoma
NHL is a malignancy of the lymphoid cells in the lymph node, bone marrow, spleen and GI system
vs
Hodgkin lymphoma is a neoplastic disease that affects lymphoid tissue
in this exam, blue dye is injected between the toes into the webbing
lymphangiogram
what is the difference between CT and MRI
CT can image bone, soft tissue and blood vessels all at the same time (5 minutes)
MRI has a much higher soft tissue detail when compared to CT but is done in 30 minutes
