Respiratory symptoms are a frequent manifestation of patients with post-acute sequela of SARS-CoV-2 (PASC), also known as long-COVID. Many cohorts of predominantly hospitalized patients have shown that a significant subset may have persistent chest computed tomography findings for more than 12 months after the acute infection. Proper understanding of the evolving long-term imaging findings and terminology is crucial for accurate imaging interpretation and patient care. The goal of this article is to review the chronic chest computed tomography findings of patients with PASC and common pitfalls.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the debilitating global pandemic known as Coronavirus disease (COVID-19). In this paper, we highlight the widespread manifestations and complications across disease systems. In addition, we present their relevant imaging findings to inform appropriate investigations and management in patients presenting to the Emergency Department with COVID-19 and its respective sequalae. Of note, we outline considerations for diagnosis of long COVID, an important medium to long term sequalae in patients with previous COVID-19 infections.

Since the 2019 worldwide pandemic, Severe Acute Respiratory Syndrome coronavirus 2 responsible for COVID-19 disease, not only had global economic repercussions but millions of individuals health were also put at risk. Like any other respiratory illness, COVID-19 has a variety of presentations and radiological features. While COVID-19 infections in the pediatric population generally present with better prognosis and lower mortality rates when compared to those of adults, in the vulnerable populations however, severe presentations are often more frequent and can have catastrophic consequences. This paper will specifically address pediatric presentations of COVID-19 including those suffering from multisystem inflammation, along with their radiologic manifestations and image findings.

COVID-19 has prominent effects on the nervous system with important manifestations on neuroimaging. In this review, we discuss the neuroimaging appearance of acute COVID-19 that became evident during the early stages of the pandemic. We highlight the underlying pathophysiology mediating nervous system effects and neuroimaging appearances including systemic inflammatory response such as cytokine storm, coagulopathy, and para/post-infections immune mediated phenomena. We also discuss the nervous system manifestations of COVID-19 and the role of imaging as the pandemic has evolved over time, including related to the development of vaccines and the emergence of post-acute sequalae such as long COVID.

This review explores imaging’s crucial role in acute Coronavirus Disease 2019 (COVID-19) assessment. High Resolution Computer Tomography is especially effective in detection of lung abnormalities. Chest radiography has limited utility in the initial stages of COVID-19 infection. Lung Ultrasound has emerged as a valuable, radiation-free tool in critical care, and Magnetic Resonance Imaging shows promise as a Computed Tomography alternative. Typical and atypical findings of COVID-19 by each of these modalities are discussed with emphasis on their prognostic value. Considerations for pediatric and immunocompromised cases are outlined. A comprehensive diagnostic approach is recommended, as radiological diagnosis remains challenging in the acute phase.

The coronavirus pandemic of 2019 (COVID-19) was arguably the most pivotal global event that current generations have witnessed, with unprecedented global challenges, and colossal effects on health systems. The financial consequences, in particular, were profound and far-reaching. Staggering estimates of up to $50.7 billion dollars per month in lost revenue for the US health system were reported by the American Hospital Association (Kaye et al., 2021). The pandemic caused significant increases in cost of drugs, disruptions to medical supply chains, day-to-day workflow, and operations in all areas of medicine and various healthcare systems. Radiology experienced a significant burden of the damage, finding itself at the forefront of the pandemic’s economic fallout (American Hospital Association).

The COVID-19 pandemic significantly strained global health systems, leading to the rapid adoption of telemedicine and changes in workforce management. Previously underused, telemedicine became an essential means of delivering healthcare while adhering to physical distancing guidelines. This transition addressed longstanding barriers like connectivity issues. Simultaneously, the radiology sector innovated by widely implementing remote reading stations, which helped manage exposure risks and conserve human resources. Moreover, the pandemic highlighted the critical role of technological advancements beyond telemedicine, such as the accelerated integration of AI in diagnostics and management. This article examines these comprehensive effects, emphasizing the remote work adaptations and innovations in healthcare systems that have reshaped both healthcare delivery and workforce dynamics during the pandemic.

Positron emission tomography/computed tomography (PET/CT) using [18F]-fluoro-2-deoxy-D-glucose (FDG) has become the mainstay imaging modality for evaluating oncology patients with certain cancers. The most common FDG PET/CT applications include staging/restaging, assessing response to therapy and detecting tumor recurrence. It is important to be aware of potential pitfalls and technical artifacts on PET/CT in the chest and abdomen to ensure accurate interpretation, avoid unnecessary intervention and optimize patient care.
