Radiological Investigation III: Pulmonary Angiogram and PET Scan

86
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Summary

In-training pulmonologists can safely perform ultrasound-guided fine-needle aspiration (US-guided FNA) for thoracic and extrathoracic lesions. This minimally invasive procedure demonstrated comparable diagnostic yield to interventional radiologists, with fewer repeat procedures needed.

Area of Science:

  • Pulmonology
  • Interventional Radiology
  • Medical Procedures

Background:

  • Ultrasound (US)-guided fine-needle aspiration (FNA) is a key diagnostic tool.
  • Assessing the feasibility of in-training pulmonologists performing US-guided FNA is important for expanding procedural capabilities.

Purpose of the Study:

  • To compare the diagnostic yield and safety of US-guided FNA performed by in-training pulmonologists versus interventional radiologists.
  • To evaluate the need for subsequent diagnostic procedures in both groups.

Main Methods:

  • Retrospective analysis of 73 patients undergoing US-guided FNA.
  • Procedures performed by both in-training pulmonologists and interventional radiologists.
  • Comparison of diagnostic yield, complication rates, and need for repeat procedures.

Main Results:

  • Comparable diagnostic yields were observed: 88.0% for pulmonologists vs. 81.3% for radiologists (P = 0.460).
  • A higher rate of second diagnostic procedures was noted in the interventional radiology group (22.9% vs. 16.0%, P = 0.488).
  • No significant complications were reported in the pulmonary group.

Conclusions:

  • In-training pulmonologists can safely and effectively perform US-guided FNA for both thoracic and extrathoracic lesions.
  • US-guided FNA by pulmonologists offers a comparable diagnostic outcome to interventional radiologists.
  • This supports the integration of US-guided FNA into pulmonology training programs.
