3-D Reconstruction of CT Scan Images in the Evaluation of Non-Specific Pulmonary Nodules
In recent years, more and more people are having lung CT scans performed to screen for various cancers. Many of them have small abnormalities detected, called "nodules", which - for a variety of reasons - doctors are unable to biopsy. As a result, many patients have their CT scans repeated on a regular basis to see if their nodules grow. This process can last several years.
Many patients experience significant anxiety during this process, when they are aware of a spot in the lung, but are not told any specific cause.
Researchers at Memorial Sloan-Kettering have developed a new way to look at lung nodules in three dimensions. The purpose of this project is to see if any change in the nodules can be detected sooner by this method than by traditional CT scans.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Pilot Study: 3-D Reconstruction of CT Scan Images in the Evaluation of Non-Specific Pulmonary Nodules|
- To collect preliminary data regarding the comparative sensitivity and specificity of conventional CT scan and three-dimensional CT for detecting the growth of nonspecific pulmonary nodules. [ Time Frame: conclusion of the study ] [ Designated as safety issue: No ]
- To determine three-dimensional characteristics of pulmonary nodules which may discriminate between benign and malignant diseases. [ Time Frame: conclusion of the study ] [ Designated as safety issue: No ]

|Estimated Primary Completion Date:||August 2014 (Final data collection date for primary outcome measure)|
Patients with one or more pulmonary nodules 5-15 mm in diameter.
Procedure: CT Scan
All patients will undergo serial CT scans after 3 months, 6 months, 9 months, 12 months, 18 months, and 24 months as is standard care. Nodules are to be scanned at 2.5mm collimation / 1.25 mm reconstruction. This resolution is necessary for volume measurements of nodules less than 1cm in diameter.
