Distinguishing Intracranial Solitary Fibrous Tumors from Meningiomas: The Diagnostic Value of T1-Weighted MRI Signal Intensity and ADC Values.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background and purposeIntracranial solitary fibrous tumors (SFTs) and meningiomas are CNS tumors that share identical imaging manifestations but exhibit different clinical behaviors. This study aimed to compare ADC values and conventional imaging features, particularly precontrast T1-weighted signal intensity, between intracranial SFTs and meningiomas. MATERIALS AND
methodsWe retrospectively evaluated 13 patients with pathologically proved intracranial SFTs and 27 patients with meningiomas who attended our hospital between January 2002 and December 2023. Signal intensity on precontrast T1-weighted imaging (compared with cerebral cortex), presence of dural tail sign, flow voids, hyperostosis, and normalized mean T1-weighted imaging values and mean ADC values were assessed.
resultsT1-weighted hyperintensity was significantly more frequent in SFTs (10/13, 76.9%) compared with meningiomas (5/27, 18.5%) (
conclusionsPrecontrast T1-weighted signal intensity is a useful characteristic for differentiating intracranial SFTs from meningiomas, with hyperintensity compared with cerebral cortex being a distinctive feature of SFTs. The combination of normalized T1-weighted imaging and ADC values provides moderate diagnostic accuracy.
