Tc-99m ciprofloxacin (Infecton) imaging effectively detects deep bacterial infections, improving early diagnosis and treatment. This sensitive radioimaging agent aids in locating infection sites for surgical intervention and monitoring treatment response.

Area of Science:

  • Nuclear medicine
  • Infectious disease diagnostics
  • Radiopharmacology

Background:

  • Deep-seated bacterial infections like abscesses, endocarditis, and osteomyelitis present diagnostic challenges, often leading to delayed treatment.
  • Accurate and timely diagnosis is crucial for effective management and improved patient outcomes.

Purpose of the Study:

  • To evaluate the diagnostic efficacy of Tc-99m ciprofloxacin (Infecton) in detecting bacterial infections.
  • To determine the sensitivity and specificity of Infecton imaging for identifying infectious foci.

Main Methods:

  • A study involving 879 patients with suspected bacterial infections who underwent Infecton imaging and microbiological evaluation.
  • Diagnostic performance was assessed against established criteria (CDC, WHO, Duke's).

Main Results:

  • Infecton imaging demonstrated an overall sensitivity of 85.4% and specificity of 81.7% in detecting infective foci.
  • Higher sensitivity (87.6%) was observed in microbiologically confirmed infections.
  • The imaging produced 528 true positives, 46 false positives, 205 true negatives, and 90 false negatives.

Conclusions:

  • Tc-99m ciprofloxacin (Infecton) is a sensitive radioimaging agent for early detection of deep-seated bacterial infections.
  • Accurate localization of infection sites with Infecton is valuable for surgical planning, such as abscess drainage.
  • Serial Infecton imaging may assist in monitoring treatment response and optimizing antimicrobial therapy duration.
