Added Value of Dual-Energy CT in COVID-19 Pneumopathy

Teaching point: The use of dual-energy instead of conventional single-energy computed tomography pulmonary angiogram can provide additional value concerning the diagnosis of COVID-19 and its complications, especially in the detection of small pulmonary embolism. Published on 2021-10-21 11:51:49

Conclusions: This represents a first step towards a complete intelligent radiomic system to optimize PE diagnosis by Q-SPECT/CT and encourages the development of a tool in the cloud for clinical use.

Conclusions: Our findings confirmed a high incidence of PE in hospitalized COVID-19 patients. Heart rate, SpO2, D-dimer, and CRP levels at admission were associated with higher rates of PE during hospitalization.

Conclusion: High D-dimer and low ferritin may predict patients with a higher risk of PE. Disproportionate hypoxia to CXR severity may help guide the need for CTPAs. These factors may represent a relatively lower inflammatory state more prone to thrombosis.

Conclusion: These findings give another perspective on PE in the context of covid-19 and emphasize the heterogeneity of its induced coagulopathy.

Recent data support the existence of a distinctive ‘vascular’ phenotype with the involvement of both pulmonary parenchyma and its circulation in COVID-19 pneumonia. Its prompt identification is important for the accurate management of COVID-19 patients. The aim is to analyse the pro and contra of the different modalities to identify the ‘vascu lar’ phenotype. Chest computed tomography scan and angiogram may quantify both parenchyma and vascular damage, but the presence of thrombosis of pulmonary microcirculation may be missed. Increasedd-dimer concentration confirms a thrombotic state, but it cannot...

CONCLUSION: By adding the functional image to the anatomical image, pulmonary angiography with MDCT and iodine mapping can demonstrate not only PTE in main, lobar and segmental arteries, but also the presence of hypoperfusion in distal vessels. This makes it a highly useful tool for the accurate diagnosis and therapeutic orientation of patients with Covid-19 lung involvement.PMID:34629642 | PMC:PMC7455161 | DOI:10.1016/j.arbres.2020.07.031

We report a case of pulmonary thrombosis in a teenager during a hypercoagulable state associated with COVID-19 (coronavirus disease 2019) caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). A condition rare in children and adolescents, pulmonary thrombosis underdiagnosis likely increases morbidity and mortality. A pulmonary thrombosis diagnosis requires a high level of suspicion and relies on the combination of clinical presentation, D-dimer elevation, and computed tomography (CT) pulmonary angiography or ventilation/perfusion scans, imaging techniques that are difficult to perform. Electrical impedance...

AbstractPurposeRecently coronavirus disease (COVID-19) caused a global pandemic, characterized by acute respiratory distress syndrome (ARDS). The aim of our study was to detect pulmonary embolism (PE) in patients with severe form of COVID-19 infection using pulmonary CT angiography, and its associations with clinical and laboratory parameters.MethodsFrom March to December 2020, we performed a prospective monocentric study collecting data from 374 consecutive patients with confirmed SARS-CoV-2 infection, using real-time reverse-transcriptase polymerase-chain-reaction (rRT-PCR) assay of nasopharyngeal swab specimens. We subs...

CONCLUSION: Results from this multicenter retrospective study did not find a significant difference in sensitivity of D-dimer for PE due to concomitant COVID-19 infection. Further study is required to determine if PE can safely be excluded based on D-dimer results alone in patients with suspected or proven COVID-19 or if adjusted D-dimer levels could have a role in management.PMID:34425044 | DOI:10.1111/acem.14348

We read with interest the research letter recently authored by Jevnikar et al. [1] about the prevalence of pulmonary embolism (PE) in patients with coronavirus disease 2019 (COVID-19) at the time of hospital admission. In this prospective multicentre study, all consecutive adult outpatients that were hospitalised with a diagnosis of COVID-19 in three tertiary French hospitals between 15 April and 23 May 2020 underwent computed tomography pulmonary angiography (CTPA). Only patients with contraindications to the examination (mainly due to contraindication for iodinated contrast administration) were excluded. The strength of ...
