Utility of PET/Computed Tomography in Infection and Inflammation Imaging.

PET Clin 2022 Jul;17(3):533-542

Division of Diagnostic Nuclear Medicine, Department of Nuclear Medicine, All India Institute of Medical Sciences, New Delhi 110029, India. Electronic address:

The role of nuclear medicine for noninvasive assessment of infection and inflammation is well established. The role of nuclear medicine is limited to initial diagnosis, recurrence, and response assessment of infections and inflammations such as tuberculosis, sarcoidosis, vasculitis, osteomyelitis, immunoglobulin G4-related diseases, and coronavirus disease 2019, as the specificity is affected by false positivity due to physiologic fluorodeoxyglucose uptake in specific organ and nonspecific uptake in postoperative cases. PET with fludeoxyglucose F 18/CT is a well-established modality for diagnosis of fever of unknown origin helping in optimized management of the patient. Read More

Community-Acquired Pneumonia in Adults: Rapid Evidence Review.

Am Fam Physician 2022 Jun;105(6):625-630

Rutgers University Robert Wood Johnson Medical School, New Brunswick, NJ, USA.

Community-acquired pneumonia (CAP) is a common condition with a hospitalization rate of about 2% in people 65 years or older and is associated with a 30-day mortality rate of 6% in hospitalized patients. In studies conducted before the COVID-19 pandemic, a bacterial pathogen was identified in 11% of patients, a viral pathogen in 23% of patients, and no organism in 62% of patients. Certain signs and symptoms can be helpful in diagnosing CAP and selecting imaging studies. Read More

Application of Imaging Examination Based on Deep Learning in the Diagnosis of Viral Senile Pneumonia.

Contrast Media Mol Imaging 2022 31;2022:6964283. Epub 2022 May 31.

Tuberculosis Department, Shanxi Linfen Third People's Hospital, Linfen City, Shanxi Province 041000, China.

Medical image classification technology, preferably which is based on the deep learning, is not only a key auxiliary diagnosis and treatment method in clinical medicine but also an important direction of scientific research. With the intensification of social aging, the incidence of viral elderly pneumonia has been on the rise and needs dedication from the research community. Doctors rely on personal theories and experience to use traditional methods to check the computed tomography (CT) images of the lungs of elderly patients one by one, which is likely to cause diagnosis errors.
