Quantitative assessment of bladder tissue properties using magnetic resonance fingerprinting: a pilot feasibility study in healthy volunteers.
Article in Radiologia brasileira. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objective: To investigate the feasibility of performing magnetic resonance fingerprinting (MRF) of the bladder and quantify the T1 and T2 relaxation times of the bladder wall in healthy female volunteers, before and after voiding. Materials and Methods: Volunteers without lower urinary tract symptoms underwent pelvic MRF. Five axial MRF slices of the bladder were obtained before and after voiding. Regions of interest were annotated on MRF T1 maps: one on the anterior bladder wall, and one on a lateral wall. Annotations made on T1 maps were subsequently copied to coregistered T2 maps. Student's t-tests for paired samples were employed to compare the T1 and T2 values obtained before voiding with those obtained after voiding. Results: Eight volunteers were included. The mean preand post-void T1 relaxation times were 1,575 ± 93 ms and 1,476 ± 138 ms, respectively. The mean preand post-void T2 relaxation times were 55 ± 21 ms and 53 ± 8 ms, respectively. The mean T1 relaxation times were 6% lower after voiding than before ( Conclusion: The use of MRF to quantify T1 and T2 relaxation times in the bladder appears to be feasible. Our results can serve as a reference for studies investigating T1 and T2 relaxation times in patients with malignant or nonmalignant bladder disorders.
