Krenning score
| Krenning score | |
|---|---|
| Purpose | grade uptake intensity of neuroendocrine tumors |
The Krenning score[1] is used to grade the uptake intensity of neuroendocrine tumors on somatostatin receptor imaging such as octreotide scan.[further explanation needed] Typically, peptide receptor radionuclide therapy (PRRT) is considered when the Krenning score is greater than 2.
Krenning Score
[edit]Grade 1: uptake < normal liver
Grade 2: uptake = normal liver
Grade 3: uptake > normal liver
Grade 4: uptake > spleen or kidneys
