Radiological Investigation III: Pulmonary Angiogram and PET Scan

337
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...

Computed Tomography01:10

Computed Tomography

7.9K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

435
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Summary

Preoperative computed tomography (CT)-guided coil localization is a safe and effective method for locating multiple lung nodules (MLNs) before video-assisted thoracoscopic surgery (VATS). This technique ensures high technical success rates for both localization and resection, improving patient outcomes.

Area of Science:

  • Thoracic Surgery
  • Diagnostic Imaging
  • Pulmonology

Background:

  • Video-assisted thoracoscopic surgery (VATS) for lung nodules benefits from preoperative localization.
  • Multiple lung nodules (MLNs) require localization for each nodule before resection.
  • Computed tomography (CT)-guided coil localization is a potential method for MLNs.

Purpose of the Study:

  • To evaluate the feasibility, safety, and clinical efficacy of preoperative CT-guided coil localization for MLNs.
  • To assess the technical success rates of coil localization and subsequent VATS wedge resection for MLNs.

Main Methods:

  • Retrospective review of 31 patients with MLNs undergoing CT-guided coil localization and VATS wedge resection.
  • Data collected included technical success rates for localization and resection, complication rates, and long-term outcomes.
  • Average of 2.2 nodules per patient were localized and resected.

Main Results:

  • High technical success rate for CT-guided coil localization (98.5%) and per-patient single-stage localization (96.8%).
  • 100% technical success rate for VATS wedge resection.
  • Low complication rate, with asymptomatic pneumothorax in 12.9% of patients. No long-term complications observed during a median 24-month follow-up.

Conclusions:

  • Preoperative CT-guided multiple coil localization is feasible and safe for guiding single-stage VATS wedge resection in patients with MLNs.
  • This technique facilitates efficient and successful management of multiple lung nodules.
