Summary
Real-time ultrasound-guided fine-needle aspiration accurately diagnosed 93.4% of abdominal masses in cancer patients. This minimally invasive biopsy technique offers significant advantages for oncologic diagnosis.
Area of Science:
- Oncology
- Radiology
- Gastroenterology
Background:
- Fine-needle aspiration (FNA) is crucial for diagnosing abdominal masses.
- Real-time guidance methods enhance FNA accuracy.
- Ultrasound guidance offers distinct advantages in oncologic biopsies.
Purpose of the Study:
- To evaluate the accuracy and advantages of real-time ultrasound-guided FNA for abdominal masses.
- To determine the efficacy of this technique in diagnosing malignant disease.
Main Methods:
- A real-time mechanical sector scanner and biopsy apparatus were used.
- Fine-needle aspirations were performed on 61 consecutive patients with suspected malignant abdominal masses.
- Masses included pancreatic (15), hepatic (32), and other gynecologic/retroperitoneal (14) lesions.
Main Results:
- The technique achieved an accuracy rate of 93.4% (57 out of 61 cases).
- Only two instances of incorrect needle placement were observed.
- Ultrasound guidance demonstrated significant advantages over other methods like CT.
Conclusions:
- Real-time ultrasound-guided FNA is a highly accurate and advantageous method for diagnosing abdominal masses in oncology.
- This technique should be considered the preferred method for fine-needle biopsy guidance in cancer patients.
