Plain-English summary
A study found that dogs with breathing problems due to fluid in the lungs (cardiogenic pulmonary edema) can be accurately diagnosed using smartphone images of their chest X-rays. Two specialists, a radiologist and a cardiologist, reviewed the images and found that both smartphone and standard computer methods were similarly effective, with high accuracy rates. This means that if your dog is having trouble breathing, a vet can quickly assess their condition using a smartphone, which could speed up treatment.

Abstract
OBJECTIVE: To compare the accuracy of radiological diagnosis of cardiogenic pulmonary oedema in dogs using two viewing platforms. MATERIAL AND METHODS: A retrospective cross-sectional study including cases admitted between January 2012 and December 2016. Thoracic radiographs from 121 dogs with and without cardiogenic pulmonary oedema were included. The study was divided into two phases, and images were interpreted by two observers: a radiologist (R1) and a cardiologist (R2). In the first phase, images were sent in JPEG format for interpretation using a smartphone. In the second phase, DICOM images were interpreted at the standard workstation using a DICOM viewer. Receiver operating characteristic curves were generated to evaluate the accuracy of each method of radiological evaluation, and Spearman correlation was used to evaluate the correlation between the evaluations performed by R1 and R2. RESULTS: The accuracy of R1 in diagnosing pulmonary oedema was 94.1% (95% confidence interval: 88.3 to 97.5) for DICOM images and 90.7% (95% confidence interval: 84.1 to 95.1) for JPEG/smartphone. The accuracy of R2 was 89.5% (95% confidence interval: 82.6 to 94.4) for DICOM images and 90.6% (95% confidence interval: 83.9 to 95.2) for JPEG/smartphone. There was no statistically significant difference between these evaluation methods. The correlation coefficient for R1 and R2 was 0.815 and 0.761, respectively. CLINICAL SIGNIFICANCE: Cardiogenic pulmonary oedema may be reliably diagnosed on thoracic radiographs viewed on a smartphone by a specialist, which may expedite treatment.
