Differentiating the Invasiveness of Lung Adenocarcinoma by Dual Energy CT Parameter

Differentiating the Invasiveness of Lung Adenocarcinoma by Dual Energy CT Using Extracellular Volume Measured in Delay Phase

Sponsor

Tang-Du Hospital

Enrollment

2,000 participants

Start Date

Jun 1, 2024

Study Type

OBSERVATIONAL

Conditions

Adenocarcinoma of Lung

Summary

The core purpose of this study is to investigate whether the extracellular volume (ECV) fraction measured in delay phase by dual energy computed tomography (DECT) can distinguish precancerous lesions from early-stage lung adenocarcinomas, which could assist clinical decision making for surgery operation indication and strategy.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study tests whether a special type of CT scan called dual energy CT (DECT) — which can analyze tissue in more detail than a standard CT scan — can distinguish between different degrees of invasiveness in lung adenocarcinoma (a common type of lung cancer), helping doctors decide on the best surgical approach. **You may be eligible if...** - You are older than 18 years - You have a pulmonary nodule (a small growth in the lung) measuring 3 cm or less - Your nodule has been confirmed by pathology to be lung adenocarcinoma - You have no history of other cancers - You had a blood test (hematocrit) within 1 week before the scan **You may NOT be eligible if...** - You are allergic to iodine-based contrast agents used in CT scans - You have another type of cancer history - You cannot complete the CT examination for medical reasons Talk to your doctor to see if this trial is right for you.
