Rad to Rad Learning: Subsolid Pulmonary Nodules on FDG PET/CT

The Radiology Partners (RP) NMMI Radiology National Subspecialty Division (NSD) presents our newest Rad to Rad Learning case.

Peer Learning Opportunity

Low-level FDG uptake in a subsolid pulmonary nodule does not exclude malignancy.

Practical Insights

• • There are no relevant threshold values when evaluating subsolid nodules.

  • Changes in nodule morphology over time may be as or more important than SUV max.

  • For subsolid nodules with low SUV max, follow-up CT is recommended, unless the nodule is enlarging over time.

Subsolid nodules with low-level FDG uptake can be malignant.
