Role of Multiphasic Computed Tomography in the Evaluation of Neoplastic Pancreatic Masses: A Single-Center Observational Study.

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
backgroundPancreatic neoplasms are associated with high morbidity and mortality, largely due to late diagnosis and challenges in accurate staging. Multiphasic computed tomography (CT) is a critical imaging tool for evaluating pancreatic masses offering detailed information on lesion characterization and surgical resectability. Precise radiological assessment is vital for treatment planning, and correlating imaging findings with histopathology improves diagnostic efficiency.
methodsThis prospective study was conducted on 50 patients with clinically suspected pancreatic neoplasms who underwent multiphasic CT imaging. Non-contrast, late arterial (pancreatic phase), and portal venous phase images were acquired following standardized contrast-enhanced CT protocols. Lesions were evaluated for size, morphology, enhancement patterns, vascular involvement, and local invasion. Resectability was assessed according to the Dutch Pancreatic Cancer Group (DPCG) criteria. Imaging findings were correlated with the final histopathological diagnosis to determine diagnostic sensitivity and specificity.
resultsIn the vast majority of cases, 43 out of 50 (86%) were diagnosed as adenocarcinoma. Other diagnoses, such as mucinous cystadenoma, solid pseudo-papillary epithelial neoplasm (SPEN), and neuroendocrine tumor, were very uncommon, each making up 4% of the total cases. Multiphasic CT showed excellent sensitivity and specificity of 100% and 85.7%, respectively, in diagnosing pancreatic neoplasms. Out of 50 cases, 16 cases were found to be resectable, 10 cases were borderline resectable, and 24 cases were non-resectable, out of which 15 cases showed distant metastasis.
conclusionMultiphasic CT is a highly accurate, non-invasive modality for the evaluation and characterization of pancreatic masses. It demonstrates a strong correlation with histopathological findings, reliably assesses vascular involvement, and predicts resectability according to DPCG criteria. Therefore, early and accurate CT-based evaluation is critical for optimal treatment planning and improving patient outcomes.
