MRI of pneumonia in immunocompromised patients: comparison with CT.

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
purposePneumonia is an important cause of mortality and morbidity in immunocompromised patients. Computed tomography (CT) is the most sensitive imaging modality for the diagnosis and surveillance of these patients. Since CT exposes the patient to ionizing radiation, we investigated the utility of magnetic resonance imaging (MRI) in the diagnosis and surveillance of immunocompromised patients with pneumonia.
methodsThe study included 40 immunocompromised patients with pneumonia documented on CT. The patients were examined by MRI within 48 hours of CT examination. All images were obtained with three different sequences: balanced fast field echo, T1-weighted turbo spin-echo (TSE), and T2-weighted TSE. Lung abnormalities were evaluated using CT and MRI.
resultsInfection was determined in 36 patients (90%), while the causative organism remained unknown in four patients (10%). In all the patients, the CT findings were consistent with infection, although three patients showed no abnormal findings on MRI. CT was superior to MRI in the detection of the tree-in-bud nodules, centrilobular nodules, and halo sign (P < 0.001, for all). A significant difference was observed between the MRI sequences and CT in terms of the number of detected nodules (P < 0.001). The nodule detection rate of MRI significantly increased in proportion to the size of the nodule (P < 0.001). All MRI sequences had almost perfect agreement with CT for the detection of consolidation (к=0.950, P < 0.001), patchy increased density (к=1, P < 0.001), pleural effusion (к=0.870, P < 0.001), pericardial effusion (к=1, P < 0.001), reverse halo sign, (к=1 P < 0.001), 10-20 mm, nodules (к=0.896, P < 0.001 for CT and B-FFE; к=0.948, P < 0.001 for CT and T1- or T2-weighted imaging) 10-20 mm, >20 mm nodules (к=0.844, P < 0.001).
conclusionAlthough CT is superior to MRI in the diagnosis of pneumonia in immunocompromised patients, MRI is an important imaging modality that can be used, particularly in the follow-up of these patients, thus decreasing to avoid ionizing radiation exposure.
