the use of smartphones and laptop at to interpret head CT imagery of the patients with acute stroke symptoms is as specific as the interpretation of head CT of these the patients with medical monitors, a study published in the American University of Radiology Newspaper sharp outside.
An acute stroke is a medical emergency that can lead to disability and even death. Therefore, in the treatment of acute stroke, the time is the brain, the longer you expect for more pity at happen. A rapid and accurate clinical assessment is imperative to determine whether immediate on-site treatment, a quick referral to a complete stroke treatment center or support management without further intervention are appropriate.
In recent decades, electronic devices such as smartphones, tablets, laptops, etc. have become essential methods of communication, data access and data sharing for the population. Their processing power is often sufficient to handle large data sets of radiological studies. It is also used to manipulate images and studies directly on portable devices. They are not recommended for primary interpretation of radiology studies, but can be used to transmit and visualize radiology studies, often in remote locations from the source of imaging data, and to facilitate the sharing of studies for a second opinion, visualization of studies and reports. by clinicians at the bedside, etc.
To evaluate and compare the clinical performance of observers interpreting computed tomography images of patients with acute stroke symptoms with a medical workstation, smartphone, or laptop, the authors conducted a retrospective study in which they used a factorial design including 2,256 interpretations (188 patients × 4 neuroradiologists × 3 reading systems). Precision equivalence tests, at a threshold of 5% and 10%, were performed for the following variables: detection of contraindications in imaging for the intravenous administration of recombinant tissue-type plasminogen activators ( hemorrhagic lesions, for example), ischemic lesions, hyperdense arteries and isolation lesions. For each clinical variable, the sensitivity, specificity and operating characteristics curves of the receptor were evaluated.
The authors observed that
- For each variable, the shapes of the ROC curves were very similar for all reading systems, indicating similar performance of the observer with different specificities and sensitivities.
- For all clinical variables, areas under the ROC curves were equivalent for all 10% threshold reading systems and were equivalent to a 5% threshold for hemorrhagic lesions, mean cerebral hyperdense artery, and ischemic injury. acute at the middle cerebral level. territory of the arteries.
- The difference between the reading time of the mobile devices and that of the medical workstation is not more than 30 seconds.
The authors conclude with equivalent diagnostic accuracy for interpreting CT scans of patients with acute stroke symptoms when using a smartphone and a laptop compared to to medical monitors
