Advanced magnetic resonance imaging techniques for structural and functional assessment of salivary glands.
Review in Radiology and oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDiagnostic paradigms for salivary gland disorders have undergone a radical transformation, shifting from purely morphological descriptions toward multi-parametric tissue characterization. This review evaluates the clinical efficacy of advanced magnetic resonance imaging (MRI) techniques, specifically quantitative T2 mapping and arterial spin labelling (ASL), in order to provide objective biomarkers for glandular pathophysiology. The use of pseudocontinuous ASL (pCASL) for non-invasive perfusion assessment and multi-dynamic multi-echo (MDME) sequences for quantitative mapping was highlighted in a methodical synthesis of recent research. Quantitative T2 mapping demonstrates high diagnostic accuracy in identifying glandular dysfunction; patients with hyposalivation exhibit significantly elevated T2 relaxation times (mean 91.85 ± 8.24 ms) compared to healthy controls (mean 80.69 ± 6.42 ms, p < 0.0001). ASL imaging reveals that parotid glands in Sjögren's syndrome are hyperemic at rest (59.2 ± 22.8 mL/min/100g) but shows dysfunctional microvascular regulation after stimulation. Furthermore, apparent diffusion coefficient (ADC) values effectively differentiate pleomorphic adenomas (> 1.4 × 10-3 mm
conclusionsAdvanced MRI provides robust, non-invasive metrics for monitoring radiation-induced damage and assessing the restorative impact of hyperbaric oxygen therapy (HBOT). By facilitating the shift to precision radiology in head and neck medicine, these technologies greatly improve patient quality of life and therapeutic planning.
