Excerpt: 

The Herder model was first proposed by Herder et al in 2005 as a method of assessing nodule risk. The authors intended for this to be an improved, more accurate version of the Mayo model, which was used commonly to assess the malignancy risk of lung nodules. Herder et al proposed that they could accurately assess the risk of malignancy using a four-point intensity scale with regards to positron emission tomography computed tomography (PETCT) fluorodeoxyglucose (FDG) avidity.
