Summary
This study examines cosmetic procedure changes on 18F-FDG PET/CT scans. Recognizing these post-treatment imaging findings, including Juvederm, silicone, and paraffin injections, prevents misinterpretation.
Area of Science:
- Medical Imaging
- Nuclear Medicine
- Radiology
Background:
- Cosmetic procedures are increasingly common, leading to diverse post-treatment changes.
- 18F-FDG PET/CT is a crucial diagnostic tool in oncology and other fields.
- Understanding imaging artifacts from non-oncologic interventions is vital for accurate interpretation.
Observation:
- Four cases illustrate cosmetic-related alterations on 18F-FDG PET/CT.
- Observed changes include post-Juvederm facial injections.
- Additional cases show effects of silicone and paraffin injections in the gluteal region and chest wall, as well as post-liposuction findings.
Findings:
- Cosmetic injections (Juvederm, silicone, paraffin) can cause focal or diffuse 18F-FDG uptake.
- Liposuction sites may exhibit increased metabolic activity on 18F-FDG PET/CT.
- These findings represent benign post-procedural changes, not neoplastic activity.
Implications:
- Familiarity with these cosmetic-related imaging patterns is essential for radiologists and nuclear medicine physicians.
- Correct identification of these changes can prevent false-positive interpretations on 18F-FDG PET/CT.
- This knowledge enhances diagnostic accuracy and avoids unnecessary patient anxiety and further investigations.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
