Purpose of review Pneumonia is one of the major infectious diseases responsible for significant morbidity and mortality throughout the world. Radiological imaging plays a prominent role in the evaluation and treatment of patients with pneumonia. This paper reviews recent innovations in the radiologic diagnosis and management of suspected pulmonary infections. Recent findings Chest radiography is the most commonly used imaging tool in pneumonias because of availability and an excellent cost… 

[Community-acquired pneumonia].

A rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging.

The diagnosis of pneumonia requires a chest radiograph (x-ray)—yes, no or sometimes?

The diagnostic role of the humble chest radiograph in the context of suspected community-acquired pneumonia is debated with some suggesting diagnostic precision is improved by chest radiographs.

Pulmonary computed tomography findings in 39 cases of Streptococcus pneumoniae pneumonia.

S segmental distributions of parenchymal abnormalities are more common than non-segmental distributions on chest CT scans of patients with S. pneumoniae pneumonia.

Severe community- acquired pneumonia – studies on imaging, etiology, treatment, and outcome among intensive care patients

Early CT might be useful in SCAP diagnostics and treatment, and the type of pneumonia did not have a significant association with hospital mortality in ICU-treated SCAP, HAP and VAP patients.

Prevalence of Streptococcus pneumonia in patients diagnosed with pneumonia by culture and PCR

The result of this study has shown the importance of streptococcus pneumonia in the society and because PCR is a fast method for detection of bacteria and can have good results in treating pneumonia before wasting time.

Computed tomography of children with pulmonary Mycobacterium tuberculosis infection.

Can chest x-ray predict pneumonia severity and its outcome in children aged 2 months - 5 years?

The basis of start of treatment should be on the clinical background and clinical severity, not only on the basis of x-ray chest findings, because late x-rays films give more chance of positive findings, multilobar infiltration or diffuse heterogeneous opacity in lungs positively correlated with clinical severity and gives idea about course and duration of hospitalization.

Nosocomial Pneumonia in the Era of Multidrug-Resistance: Updates in Diagnosis and Management

This narrative review aims to critically review what is new in the field of NP, specifically, diagnosis and antibiotic treatment, and recent developments in rapid microbiological confirmation are presented.

Clinical, clinicopathologic, and radiographic findings in dogs with aspiration pneumonia: 88 cases (2004-2006).

In dogs, aspiration pneumonia was often associated with abnormalities in pulmonary auscultation in the absence of objective changes in physical examination findings, however, neutrophilia, hypoalbuminemia, and hypoxemia were frequently detected, and radiographic evidence of infiltrates in the right middle lung lobe was common.

Clinical Course and Computed Tomography Abnormalities Associated without and with Concomitant Infection in Patients with Pandemic Influenza A (H1N1) 2009 Virus Infection

The possibility of H1N1 pneumonia with co-infections should be considered if there are CT findings other than pure H1n1 pneumonia, and the secondary infectious process may cause additional CT abnormalities.



Radiology of bacterial pneumonia.

Radiologic manifestations of round pneumonia in adults.

Any patient with a pulmonary nodule that does not decrease in size or resolution after antibiotic treatment should be further assessed with bronchoscopy, transthoracic needle biopsy, or other diagnostic procedures.

High resolution CT findings in community-acquired pneumonia.

Characteristic HRCT findings of both bacterial and atypical pneumonia were demonstrated and seemed to reflect pathologic findings and the manner of lesional progression, which may support the appropriate antibiotic therapy in medical practice.

Pneumonia: high-resolution CT findings in 114 patients

High-resolution CT scans obtained in 114 patients with bacterial, Mycoplasma pneumoniae, viral, fungal, and Pneumocystis carinii pneumonias were analyzed retrospectively for presence, pattern, and distribution of abnormalities.

Spectrum of CT Findings in Nosocomial Pseudomonas aeruginosa Pneumonia

The distribution of consolidation, frequency and distribution of nodules, and frequency of necrosis did not differ significantly between patients with and without other positive cultures, and with CT, PAP most commonly presents with multifocal airspace consolidation.

Chest radiographic manifestations of severe acute respiratory syndrome in health care workers: the Toronto experience.

The chest radiographic manifestations of severe acute respiratory syndrome (SARS) in previously uninfected health care workers during the early stages of an outbreak in Toronto, Canada is described.

Bacterial or nonbacterial pneumonia: accuracy of radiographic diagnosis.

The initial chest radiographs of 31 patients with laboratory-proved pneumonia were evaluated by a panel of 6 radiologists who had no prior knowledge of the clinical data. No statistical reliability

Epidemiology and outcomes of health-care-associated pneumonia: results from a large US database of culture-positive pneumonia.

Compared with CAP, non-CAP was associated with more severe disease, higher mortality rate, greater LOS, and increased cost, and the present analysis justified HCAP as a new category of pneumonia.
