Abstract
COVID-19 infection is the theme number one in the last months. From the radiological point of view, COVID-19 infection has some specific signs especially on computed tomography (CT) of the lung.
Chest X ray in not recommended as a screening method for the detection of the infection. CT of the lung can be completelly negative in the first days of the infection.
In the next days some specific signs can appear, like ground glass opacities bilaterally in subpleural space. Ground glass opacities can be seen alone or together with reticulations.
Other typical signs are lienar opacities and consolidations. In the case of untransportable patient it is possible to use bed side ultrasound to detect lung involvement but by using this method it is impossible to detect the real extent of the lung involvement.
