Visual PET/CT scoring of mesenteric FDG uptake to differentiate between tuberculous peritonitis and peritoneal carcinomatosis

P 1 had a sensitivity (the accuracy fordiagnosis of PC) of 80.4% and a specificity (the accuracy for diagnosis of TBP) of 75.0%.CONCLUSIONA visual PET/CT scoring system based on mesenteric FDG uptake performed well in differentiating between TBP and PC.

📌 3 Key Takeaways

🎯

Objective & Hypothesis:PURPOSEWe aimed to differentiate tuberculous peritonitis (TBP) from peritoneal carcinomatosis (PC)using a visual positron-emission tomography/computed tomography (PET/CT) scoring systembased on mesenteric fluorodeoxyglucose (FDG) uptake.METHODSPET/CT scans from 31 patients with TBP and 92 patients with PC were retrospectively reviewed.

📊

Key Findings & Data:Avisual PET/CT scoring system for mesenteric FDG uptake was used according to the following characteristics: FDG uptake intensity (low = 0, moderate = 1, high = 2), FDG uptake deposits (uniform= 0, irregular = 1, ascitic = 2), FDG uptake focality (diffuse = 0, segmental = 1, focal = 2), nodularityon the corresponding CT (nonnodular = 0, micronodular = 1, macronodular = 2) and mesenteric lymphadenopathy (absent = 0, lymphadenopathy without FDG uptake = 1, lymphadenopathywith FDG uptake = 2).

💡

Conclusion & Impact:P 1 had a sensitivity (the accuracy fordiagnosis of PC) of 80.4% and a specificity (the accuracy for diagnosis of TBP) of 75.0%.CONCLUSIONA visual PET/CT scoring system based on mesenteric FDG uptake performed well in differentiating between TBP and PC.

Avisual PET/CT scoring system for mesenteric FDG uptake was used according to the following characteristics: FDG uptake intensity (low = 0, moderate = 1, high = 2), FDG uptake deposits (uniform= 0, irregular = 1, ascitic = 2), FDG uptake focality (diffuse = 0, segmental = 1, focal = 2), nodularityon the corresponding CT (nonnodular = 0, micronodular = 1, macronodular = 2) and mesenteric lymphadenopathy (absent = 0, lymphadenopathy without FDG uptake = 1, lymphadenopathywith FDG uptake = 2). The FDG uptake intensity, deposits, focality, nodularity and mesentericlymphadenopathy scores between TBP and PC were compared using chi-square tests. The diagnostic performance of this scoring system for differentiating TBP from PC was analyzed using areceiver operating characteristic (ROC) curve. P 1 had a sensitivity (the accuracy fordiagnosis of PC) of 80.4% and a specificity (the accuracy for diagnosis of TBP) of 75.0%.CONCLUSIONA visual PET/CT scoring system based on mesenteric FDG uptake performed well in differentiating between TBP and PC.
