Mycoplasma pneumoniae pneumonia, psittacosis pneumonia, pulmonary infections, etc.
Conditions
Interventions
Gold Standard:Patients had definite etiological diagnosis results: Mycoplasma pneumoniae pneumonia (MPP) was confirmed or excluded by gold standards such as Mycoplasma nucleic acid testing (e.g., PCR)
viral pneumonia or fungal pneumonia was diagnosed via viral

Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: 1. Received a thin-slice chest CT scan without receiving targeted anti-mycoplasma treatment before the scan. 2. Have clear etiological diagnosis results (gold standard) : mycoplasma pneumonia: PCR, culture or serological specific antibody test positive. Other pneumonia (viral/bacterial/fungal) : positive result of corresponding nucleic acid/antigen test or culture. 3. Normal control: no evidence of pulmonary infection and no abnormal CT images. 4. Have complete baseline clinical data and high-quality CT imaging data. 5. All patients were over 18 years old;
Exclusion criteria
Exclusion criteria: 1. Poor CT image quality (severe motion or respiratory artifacts). 2. Combined with pulmonary diseases that seriously interfere with imaging features (such as active tuberculosis, lung cancer, diffuse pulmonary fibrosis). 3. The inflammatory lesion is too small (maximum diameter < 5mm) to reduce the interference of partial volume effect. 4. Missing clinical or imaging data.
