Diagnostic Value of Spectral CT-Derived Extracellular Volume Fraction in the Early Detection of Sigmoid Colon Metastasis from Bladder Cancer: A Case Report.

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
introductionThe occurrence of colorectal metastasis from bladder cancer is an uncommon phenomenon, and the early identification of metastatic foci poses a certain challenge. CASE PRESENTATION: A 77-year-old male patient who had been diagnosed with bladder carcinoma underwent radical cystectomy with an ileal conduit. Postoperative spectral contrast-enhanced CT revealed no definitive intra-abdominal metastatic lesions. Following a period of 1 month, the patient presented with abdominal pain and melena, and subsequent spectral contrast-enhanced CT revealed a metastatic lesion in the sigmoid colon and multiple hepatic metastases. A retrospective analysis of the initial postoperative extracellular volume fraction (ECV) images from spectral CT clearly delineated the metastatic lesion in the sigmoid colon, despite the absence of abnormalities on conventional images.
conclusionsThis case report suggests that multiparametric spectral CT, particularly ECV imaging, may detect subtle tissue changes before apparent morphological changes, indicating its potential value in the recognition of early metastatic lesions. To our knowledge, this is the first reported case demonstrating the potential value of spectral CT-derived ECV imaging for the early detection of sigmoid colon metastasis from bladder cancer.
