Krenning score
The Krenning score[1] is used to grade the uptake intensity of neuroendocrine tumors on somatostatin receptor imaging such as octreotide scan. Typically, peptide receptor radionuclide therapy (PRRT) is considered when the Krenning score is greater than 2.
| Krenning score | |
|---|---|
| Purpose | grade uptake intensity of neuroendocrine tumors |
Krenning Score
Grade 1: uptake < normal liver
Grade 2: uptake = normal liver
Grade 3: uptake > normal liver
Grade 4: uptake > spleen or kidneys
gollark: Bees is the precursor to apiforms.
gollark: I'm just on Discord *constantly*, to remain synchronized with the internet hive mind.
gollark: Bees WILL be initiated
gollark: > i think i should quit discord for a while and only check it like once a month or somethingno.
gollark: Oh, cool idea; map them to names using the unicode character database somehow?
