abstract = {The aim of this retrospective study was to evaluate the
correlation between findings from somatostatin receptor
(SSTR) PET/CT and histopathology in patients with suspected
intracranial meningiomas. Methods: We conducted a
retrospective analysis of 8,077 SSTR imaging studies
recorded in our institutional database between 2006 and
2021. In total, 223 SSTR PET/CT scans were performed for
suspected meningioma, and 240 lesions were matched with
histopathology results within 4 mo. Reports from SSTR PET/CT
scans and histopathology were retrospectively reviewed to
assess the presence of intracranial meningiomas. The
positive and negative predictive values, sensitivity,
specificity, and overall diagnostic accuracy of SSTR PET/CT
were calculated. The SUVmax, SUVmean, and SUVpeak were
determined for each lesion. Results: In 222 $(92.5\%)$ of
240 lesions, meningioma was accurately identified by SSTR
PET/CT and confirmed by histopathology. In 7 cases
$(2.9\%),$ SSTR PET/CT suspected meningioma was not
confirmed by histopathology (false-positive). Furthermore,
in 11 cases $(5\%),$ meningioma was neither suspected by
SSTR PET/CT nor confirmed by histopathology (true-negative
result). There were no false-negative findings in our
cohort. SSTR PET/CT demonstrated a sensitivity of $100\%$
$(95\%$ CI, $98.4\%-100\%)$ and a specificity of $61.1\%$
$(95\%$ CI, $35.8\%-82.7\%)$ in detecting meningiomas.
Positive predictive value was $96.9\%$ $(95\%$ CI,
$93.8\%-98.8\%),$ and negative predictive value was $100\%$
$(95\%$ CI, $71.5\%-100\%).$ The overall diagnostic accuracy
was $97.1\%.$ The receiver-operating-characteristic analysis
for SUVmax in predicting histopathology results showed an
area under the curve of $94\%,$ indicating an excellent
ability of SUVmax to distinguish between positive and
negative histopathologic findings. Conclusion: SSTR PET/CT
is a precise imaging modality for detecting intracranial
meningiomas, as demonstrated by its high sensitivity.
However, in $2.9\%$ of cases, despite a positive PET/CT
result, histopathology did not confirm the presence of a
meningioma. Integration of MRI, histopathology, and SSTR
PET/CT supports informed treatment decisions.},
