Comparison of contrast-enhanced CT (ceCT) and FAPI-PET in detecting peritoneal carcinomatosis in patient with advanced ovarian carcinoma. (A) ceCT shows subtle peritoneal thickening that is difficult to delineate. (B) Maximum-intensity-projection image demonstrating diffuse intense FAPI uptake corresponding to extensive peritoneal carcinomatosis. (C) FAPI-PET shows intense uptake corresponding with peritoneal carcinomatosis, with improved lesion conspicuity over ceCT.

Representative case from the non-nitroglycerin cohort. A 92-year-old man who did not receive sublingual nitroglycerin because of severe aortic stenosis. The Agatston coronary artery calcium score was 5438. (A) Curved multiplanar reformatted CCTA image reconstructed at 0.4-mm slice thickness using a Bv60 kernel and QIR strength 3 demonstrates diffuse multifocal mild luminal stenoses related to extensive calcified atherosclerotic plaque. (B) Invasive coronary angiography confirmed multifocal mild stenoses without evidence of obstructive coronary artery disease.

Serial axial chest CT scans demonstrating the longitudinal evolution of small pure ground-glass nodules (pGGNs) incidentally detected during a routine wellness assessment. (A) Images in a 37-year-old woman with a family history of lung cancer show a nodule with the progressive growth pattern (box). The baseline CT scan, obtained in October 2017, demonstrates a pure ground-glass nodules in the right lower lobe. Consecutive CT scans obtained from 2017 to 2022 show the continuous enlargement of the nodule during active surveillance. The maximum diameter of the nodule increased from 5.6 mm in 2017 to 10.2 mm in 2022. (B) Images in a 45-year-old man show a nodule with the indolent growth pattern (box). The baseline CT scan, obtained in April 2018, demonstrates a pure ground-glass nodules in the left lower lobe. Consecutive CT scans obtained from 2019 to 2023 show that the nodule remained radiographically stable during CT surveillance. The maximum diameter of the nodule was 5.4 mm in 2018 and 6.1 mm at the final surveillance scan in 2023.
