Summary
This study shows that 18F-FDG PET imaging is valuable for managing patients with isolated pleural lesions, aiding in diagnosis and recurrence detection. PET-CT is expected to further improve its diagnostic accuracy.
Area of Science:
- Nuclear Medicine
- Oncology
- Radiology
Background:
- Limited data exists on the utility of 18F-FDG imaging for isolated pleural lesions.
- Pleural lesions require accurate characterization for appropriate patient management.
Purpose of the Study:
- To evaluate the role of 18F-FDG imaging (PET or CDET) in patients with apparently isolated pleural lesions.
- To assess the impact of 18F-FDG imaging on patient management and diagnostic accuracy.
Main Methods:
- 16 patients with isolated pleural lesions underwent 22 evaluable 18F-FDG examinations.
- Imaging was performed using PET or coincidence detection gamma cameras.
- Indications included characterization of pleural masses, mesothelioma staging, and suspicion of recurrence.
Main Results:
- Malignant pleural lesions showed [18F]-FDG uptake in all cases.
- One false positive due to inflammation; three false negatives for lymph node invasion.
- Patient management changed correctly in 25% of cases based on imaging findings.
Conclusions:
- [18F]-FDG imaging impacts patient management for solitary pleural lesions, detecting recurrences effectively.
- PET-CT is anticipated to enhance diagnostic capabilities, overcoming current limitations in anatomical detail.
