Materials and Methods A comprehensive literature search was conducted in PubMed, Embase, Web of Science, and Cochrane through May 12, 2025, to identify human studies reporting quantitative liver background uptake for the four PSMA-targeted PET radiotracers of interest. For each eligible study, liver background uptake was extracted as standardized uptake values (SUVs) and summarized and compared by radiotracer using random effects models with robust variance estimation. Results Among 652 unique records, 17 studies with 1497 total patients met inclusion criteria and reported liver background SUVs. Summary mean liver background SUV was 5.0 (95% CI: 3.6, 6.3) for ¹⁸F-piflufolastat, 5.1 (95% CI: 4.3, 5.9) for ⁶⁸Ga-PSMA-11 (<i>P</i> = .579 compared with ¹⁸F-piflufolastat), 7.2 (95% CI: 6.3, 8.2) for ¹⁸F-flotufolastat (<i>P</i> = .005), and 12.1 (95% CI: 11.4, 12.9) for ¹⁸F-PSMA-1007 (<i>P</i> < .001). Conclusion Liver background uptake differed across PSMA-targeted PET radiotracers and may influence patient eligibility for PSMA-targeted therapy when liver activity is used as a reference for defining PSMA-positive metastatic prostate cancer. <b>Keywords:</b> PET, Genital/Reproductive, Prostate, ⁶⁸Ga-PSMA-11, ¹⁸F-piflufolastat, ¹⁸F-flotufolastat, ¹⁸F-PSMA-1007, PSMA-targeted PET, PSMA-targeted Therapy <i>Supplemental material is available for this article.</i> © RSNA, 2026.</p>","PeriodicalId":20786,"journal":{"name":"Radiology.

Materials and Methods This single-center retrospective study (January 2000-December 2024) included adults with intracranial meningioma and preoperative MRI scans. Lesions were manually segmented and normalized to the Montreal Neurological Institute 152 template space and analyzed with volume-adjusted permutation testing and false discovery rate correction. Results The final cohort comprised 1333 patients (mean age, 58 years ± 13 [SD], 1064 female [79.8%] and 269 male [20.2%] patients) with 1676 intracranial meningiomas. Density analysis revealed a cluster in the anterior or middle skull base. Symptomatic presentation was localized to the bilateral motor and premotor cortex, deep frontobasal regions, and anteromedial skull base (26ߙ141 voxels; maximum <i>z</i> score [max <i>z</i>] = 7.70; <i>q</i> < .05). Symptom-specific clusters included focal deficits in the left precentral and anteromedial junction of the skull base (3163 voxels; max <i>z</i> = 9.26; <i>q</i> < .05), epilepsy in the bilateral premotor region including supplementary motor area and middle frontal gyrus (929 voxels; max <i>z</i> = 5.89; <i>q</i> < .05), and radioclinical signs of elevated intracranial pressure in the deep right frontal and left cerebellar regions (19 066 voxels; max <i>z</i> = 7.62; <i>q</i> < .05). The resection probability was clustered in the anterior skull base, middle skull base, bilateral supplementary motor area, left precentral gyrus, and deep frontobasal regions (56 649 voxels; max <i>z</i> = 9.50; <i>q</i> < .05). Among resected tumors with available histology, tumors with a higher World Health Organization grade (grade 2-3) were localized to a right frontal cluster along the superior and middle frontal gyri (97 voxels; max <i>z</i> = 5.76; <i>q</i> < .05). Conclusion The voxelwise maps of 1676 meningiomas revealed that tumor location was associated with symptoms, resection probability, and malignancy grade. <b>Keywords:</b> Intracranial Meningioma, MRI Mapping, Brain Atlas, Skull Base, Neurosurgery <i>Supplemental material is available for this article.</i> © RSNA, 2026 See also commentary by Todea in this issue.</p>","PeriodicalId":20786,"journal":{"name":"Radiology.
