We included patients with suspected tumor or bland thrombus on PET\/CT who underwent histopathological evaluation and\/or confirmatory imaging or clinical follow\u2010up. Sensitivity and specificity were estimated using a random\u2010effects model. Positive and negative likelihood ratios (LR+ and LR\u2212) and diagnostic odds ratio (DOR) were derived from the pooled estimates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Five studies were included (217 patients; mean age 55.9\u2009years). Hepatobiliary malignancies (49%) and renal tumors (24%) were the most frequent, with the renal vein, portal vein, and inferior vena cava most frequently involved. Maximum standardized uptake value (SUVmax) was significantly higher in malignant compared to bland thrombi, with reported diagnostic cutoffs ranging from 2.25 to 3.63. PET\/CT scan showed diagnostic accuracy with pooled sensitivity 92.2%, specificity 94.2%, LR\u2212 0.121, LR+ 10.919, and DOR of 91.770.<\/jats:p>\n                  <\/jats:sec>\n
