“…High-resolution chest CT findings of SARS have been described by Wong et al, 17 Chan et al, 18 and Paul et al 14 The most common findings are ground-glass opacities and crazy paving. Hui et al 19 suggest that high-resolution chest CT is useful for early diagnosis of SARS in patients with negative radiographs.…”

Acute respiratory illness is defined as one or more of the following: cough, sputum production, chest pain, or dyspnea (with or without fever). The workup of these patients depends on many factors, including clinical presentation and the suspected etiology. This study reviews the literature on the indications and usefulness of radiologic studies for the evaluation of acute respiratory illness in the immunocompetent patient. The following recommendations are the result of evidence-based consensus by the American College of Radiology Appropriateness Criteria Expert Panel on Thoracic Radiology. Chest radiographs are usually appropriate in (1) patients with positive physical examination or risk factors for pneumonia, (2) for the assessment of complicated pneumonia, or (3) in cases of emerging infections and biological warfare agents such as severe acute respiratory syndrome, H1N1, and anthrax. Computed tomography, although having a more limited role, is usually appropriate (1) in the assessment of complicated pneumonia and (2) in patients with suspected severe acute respiratory syndrome, H1N1, or anthrax and a normal radiograph.

Coronavirus Disease (COVID-19): Spectrum of CT Findings and Temporal Progression of the Disease

Coronavirus disease is an emerging infection caused by a novel coronavirus that is moving rapidly. High resolution computed tomography (CT) allows objective evaluation of the lung lesions, thus enabling us to better understand the pathogenesis of the disease. With serial CT examinations, the occurrence, development, and prognosis of the disease can be better understood. The imaging can be sorted into four phases: early phase, progressive phase, severe phase, and dissipative phase. The CT appearance of each phase and temporal progression of the imaging findings are demonstrated.

“…Both focal and multifocal opacities most commonly involve the lower lobes and show a predilection for the peripheral aspects of the lungs. The most common findings on CT scanning are ground glass opacities (GGO), these occurring in about two-thirds of cases during the first week [10][11][12] (Fig. Several patterns of disease progression have been described, most patients showing peak radiographic abnormalities between 6 and 12 days after the onset of symptoms.…”

Severe acute respiratory distress syndrome (SARS) caused by SARS-associated coronavirus (SARS-CoV) is a systemic infection that clinically manifests as progressive pneumonia. During the initial phases of infection the virus causes pauci-inflammatory alveolar and interstitial edema that result in imaging abnormalities dominated by ground glass opacities (GGO). Severe SARS cases can develop radiologic and pathologic findings of diffuse alveolar damage. Although radiologic evidence of acute bronchiolitis is absent, SARS-CoV also infects ciliated airway epithelium, probably accounting for respiratory transmissibility of the virus. Radiologic recovery from SARS can be complete, but computed tomography images often show persistent GGO and reticular opacities, some of which reflect pathologic findings of fibrosis. Long-term follow-up imaging of survivors shows gradual decrease of GGO and reticulation with persistent air trapping in some patients. The latter is evidence of small airway disease that is not radiologically evident at the onset of the disease.
