[A new approach in the diagnosis of lung lesions in patients with COVID-19: lung ultrasound protocol versus CT scan].

Aim: To develop a protocol for ultrasound diagnostics of COVID-19 pneumonia and to assess the diagnostic capabilities of the method in comparison with computer tomography (CT).

Materials And Methods: The study included 59 patients with a new coronavirus infection. In order to identify changes in the lung tissue characteristic of a new coronavirus infection, we used a special protocol for ultrasound of the lungs, which was developed by us in such a way that the data obtained were compared by segment with the results of CT of the lungs.

[Comparative capabilities of the speckle-tracking echocardiography technologiesin two-dimensional and three-dimensional modes in the detection of subclinical cardiotoxicity in patients with breast cancer].

Aim: The study was to assess the deformation properties of the left ventricle (LV) myocardium in patients with breast cancer initially and after anthracycline chemotherapy according to 2D and 3D speckle-tracking echocardiography (STE).

Material And Methods: the study included 99 patients with triple negative breast cancer with hypertensionandnormotension. All patients underwent standard transthoracic echocardiography with assessment of systolic function of the LV.
