Two patients with paroxysmal atrial fibrillation developed pulmonary vein stenosis (PVS) after AF ablation, with Case 1 being a female in her 50s and Case 2 a male in his 60s.
The first patient showed high-degree left superior PVS 15 months post-ablation, while the second had progressive PVS nine months later, confirmed through contrast-enhanced CT and ventilation-perfusion scans.
PVS is a rare complication of AF ablation that can lead to severe issues if untreated, and the case report emphasizes the importance of V/Q scans in assessing PVS despite its common association with pulmonary embolism evaluations.
Somatostatin receptor scintigraphy (SRS) with In-DTPA-DPhe-octreotide is key for managing neuroendocrine neoplasms, but precise quantification is lacking.*

This study analyzed 21 patients, calculating standardized uptake values (SUVs) for liver, kidney, and spleen to improve the assessment of neuroendocrine tumors (NETs) through a combination of visual scoring and quantitative analysis.*
-
Results showed significant correlations between higher SUVs and visual scores, confirming the utility of combined visual and quantitative methods for better lesion characterization and staging of NETs.*
