Revolution evo ct scanner

The CAC score was measured using a 128-slice MDCT scanner (GE Healthcare Revolution EVO CT Scanner). The scanning parameters of the 128-slice MDCT were prospective EKG gating (120 kV tube voltage, 180–270 mA tube current and 2.5-mm slice thickness). Calcification in the coronary arteries was defined as a high-density lesion >130 HU according to the Agatston method. The parameters of all images were calculated and summed using a workstation (AW VOLUMESHARE 7, GE MEDICAL SYSTEMS SCS, Buc, Yvelines, France). Separate CAC scores were recorded on medical charts, and the total CAC score was categorized into four stages as described by Agatston et al. [14 (link)]. CAC stage-1 was defined as a total CAC score of 0, CAC stage-2 as a total CAC score between 1–99, CAC stage-3 as a total CAC score between 100–399, and CAC stage-4 as a total CAC score of ≥400.

This case series study was approved by the local ethics committee (approval ID: 12-2021). The study included 24 diabetic patients who had recovered from diagnosed COVID-19 and presented with ROCM complications. All patients were hospitalized in the ENT Department of Clinics of Samara State Medical University between November and December 2021. As part of their workup, the patients underwent chest and paranasal sinus CT scans via a 128-slice Revolution EVO CT scanner (General Electric, Moscow, Russia) with and without contrast enhancement; 5 of these patients also underwent contrast-enhanced MRI of the skull orbits and brain using the 1.5-T Magnetom Aera (Siemens AG, Munich, Germany). All patients underwent surgical treatment, and tissue samples were retrieved for histological examination for mucormycosis (Figure 1).
