Assessment of the Diaphragm Thickness Decrease in Critically Ill COVID-19 Patients: Could Computed Tomography Be of Aid Regarding Diaphragm Muscle Mass?

Introduction: The diaphragm has a significant clinical value on respiratory performance. There is little literature on the use of thorax computed tomography for the purpose of identifying alterations in diaphragm thickness in critically ill patients diagnosed with COVID-19. The present study aims to investigate dynamic changes in muscle thickness and its association with clinical outcomes.

Total Psoas Area and Psoas Density Assessment in COVID-19 Patients Using CT Imaging - Could Muscle Mass Alteration During Intensive Care Hospitalization be Determined?

Background: Since its debut, as reported by the first published studies, COVID-19 has been linked to life-threatening conditions that needed vital assistance and admission to the intensive care unit. Skeletal muscle is a core element in an organism's health due to its ability to keep energy balance and homeostasis. Many patients with prolonged hospitalization are characterized by a greater probability prone to critical illness myopathy or intensive care unit-acquired weakness.

Comparing the Diagnostic Performance of ECG Gated versus Non-Gated CT Angiography in Ascending Aortic Dissection: A GRRAS Study.

Rationale and Objective: Thoracic CT angiography (CTA) for ascending aortic dissection, a life-threatening emergency, is performed routinely without Electrocardiographic (ECG) gating, therefore allowing the apparition of a pulsation artefact. We aimed to evaluate and compare the diagnostic performance, the inter and intra-reporter agreement of ECG gated CTA and non-ECG gated CTA for detecting ascending aortic dissection, considering their training level. Our hypothesis is that ECG gated CTA has superior diagnostic accuracy for ascending aortic dissection compared to non-gated CTA.
