Summary
Fine needle aspiration biopsy (FNAB) guided by imaging is highly effective, achieving 90% sensitivity and 100% specificity. This minimally invasive technique offers accurate cancer diagnosis with a low complication rate.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Minimally invasive diagnostic procedures are crucial in modern healthcare.
- Image-guided biopsies enhance diagnostic accuracy and safety.
- Fine needle aspiration biopsy (FNAB) is a widely used technique.
Purpose of the Study:
- To evaluate the efficacy and safety of image-guided FNAB.
- To determine the diagnostic accuracy of FNAB in a tertiary care setting.
- To assess the complication rate associated with FNAB procedures.
Main Methods:
- Retrospective analysis of 66 image-guided FNAB procedures (CT or ultrasound).
- Assessment of technical success, sensitivity, specificity, and concordance with final diagnosis.
- Review of complication rates and patient outcomes.
Main Results:
- 97% technical success rate with 66 procedures performed.
- Overall sensitivity of 90% and specificity of 100%.
- Low complication rate (12%) of minor, conservatively managed events. 91.5% concordance with final diagnosis.
Conclusions:
- Image-guided FNAB is a highly sensitive and specific diagnostic tool.
- The procedure demonstrates a high technical success rate and low complication profile.
- Adequately performed FNAB is a valuable diagnostic method for malignancy detection.
