The dataset includes annotated 2D CXR images for lung nodule detection, capturing the longest diameter and its perpendicular diameter, along with various characteristics such as density, margins, and location. This dataset is designed for using CXR as a first-line screening tool to assess the likelihood of nodule malignancy, aiding in the decision of whether further examinations, such as CT scans or biopsies, are necessary. This tool is especially beneficial for remote areas and telemedicine applications, where access to advanced diagnostic facilities may be limited. By providing an initial assessment of nodule characteristics and potential malignancy, the dataset helps prioritize patients who need immediate further investigation, improving early detection and treatment outcomes in underserved regions.
