Summary
Lung scans are crucial for lung volume reduction surgery (LVRS) candidate selection and determining resection percentages. Anatomical quantitation of lung perfusion images aids thoracic surgeons in these critical decisions.
Area of Science:
- Pulmonary Medicine
- Thoracic Surgery
- Medical Imaging
Background:
- Lung volume reduction surgery (LVRS) is a key treatment for severe emphysema.
- Accurate patient selection and determination of resected lung volume are vital for successful LVRS outcomes.
- Lung scans are essential diagnostic tools in this process.
Purpose of the Study:
- To describe the anatomical quantitation of lungs using perfusion imaging.
- To demonstrate how lung scan analysis aids in selecting candidates for LVRS.
- To illustrate the role of imaging in determining the extent of lung resection during LVRS.
Main Methods:
- Utilized automatic and manual regions of interest on lung perfusion images.
- Analyzed posterior and posterior oblique views.
- Calculated percent function for individual lung lobes.
Main Results:
- Evaluated 172 patients using the described technique.
- 136 of the evaluated patients subsequently underwent LVRS.
- The method provided quantitative data on lung lobe function.
Conclusions:
- Anatomical placement of regions of interest in lung perfusion images is effective.
- This technique assists thoracic surgeons in selecting appropriate LVRS candidates.
- It also aids in precisely determining the volume of lung to be resected during surgery.
