MR imaging of pulmonary lung nodules during one lung flooding: first morphological evaluation using an ex vivo human lung model.
Article in Magma (New York, N.Y.), 2020. 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
objectivesMagnetic resonance imaging in pulmonary oncology is limited because of unfavourable physical and physiological conditions in ventilated lung. Previous work showed operability of One Lung Flooding using saline in vivo in MR units, and that valuable conditions for ultrasound and thermal-based interventions exist. Therefore, this study investigates the morphological details of human lung during Lung Flooding to evaluate its further value focusing on MR-guided interventions. MATERIALS AND
methodsMR imaging was performed on 20 human lung lobes containing lung cancer and metastases. Lobes were intraoperatively flooded with saline and imaged using T1w Gradient Echo and T2 Spin Echo sequences at 1.5 T. Additionally, six patients received pre-operative MRI.
resultsDuring lung flooding, all lung tumours and metastases were visualized and clearly demarked from the surrounding lung parenchyma. The tumour mass appeared hyperintense in T1w and hypointense in T2w MR imaging. Intra-pulmonary bronchial structures were well differentiated in T2w and calcification in T1w MR sequences.
conclusionSuperior conditions with new features of lung MRI were found during lung flooding with an unrestricted visualization of malignant nodules and clear demarcation of intra-pulmonary structures. This could lead to new applications of MR-based pulmonary interventions such as laser or focused ultrasound-based thermal ablations.
