Photon\u2010counting\n CT<\/jats:styled-content>\n (\n PCT<\/jats:styled-content>\n ) offers improved spatial resolution and contrast\u2010to\u2010noise ratio (\n CNR<\/jats:styled-content>\n ) compared with conventional\n CT<\/jats:styled-content>\n (\n CCT<\/jats:styled-content>\n ), potentially enhancing diagnostic performance. In this retrospective single\u2010center study, patients diagnosed with pericardial metastases by transthoracic echocardiography (TTE) between April and September 2025, who underwent both unenhanced and contrast\u2010enhanced chest CT were included. After Propensity Score Matching (PSM), two groups were established: the PCT group (\n n<\/jats:italic>\n \u2009=\u200911; reconstructions at 0.4 and 1\u2009mm) and the CCT group (\n n<\/jats:italic>\n \u2009=\u200922). Diagnostic sensitivity, image quality, and radiation dose were assessed, with TTE as the reference standard. PCT\u20100.4\u2009mm demonstrated the highest overall sensitivity (91.5%) and small\u2010lesion sensitivity (88.9%), followed by PCT\u20101\u2009mm (87.2% and 83.3%) and CCT\u20101\u2009mm (86.1% and 78.6%). Although not statistically significant, PCT showed consistently better lesion detection. The PCT\u20100.4\u2009mm group showed higher standardized CNR versus CCT\u20101\u2009mm (Tukey\u2013Kramer\n p<\/jats:italic>\n \u2009=\u20090.021) but not versus PCT\u20101\u2009mm (\n p<\/jats:italic>\n \u2009=\u20090.641); overall one\u2010way ANOVA\n p<\/jats:italic>\n \u2009=\u20090.020, whereas SNR did not differ among groups (ANOVA\n p<\/jats:italic>\n \u2009=\u20090.18). Radiation exposure was significantly lower with PCT than CCT (ED: 11.7\u2009\u00b1\u20093.9 vs. 20.6\u2009\u00b1\u20096.6\u2009mSv;\n p<\/jats:italic>\n \u2009<\u20090.001). Compared with the 1\u2010mm CCT reconstruction, the 0.4\u2010mm PCT showed a trend toward improved detection of both overall and small pericardial metastases, enhanced image quality, and reduced radiation dose, highlighting its potential clinical value in managing pericardial metastases.\n
