Images (DICOM… The features systematically scored tumors and identified imaging phenotypes which exhibited survival differences. Python code to visualize the annotation boxes on top of the DICOM images can be downloaded here. The images were retrospectively acquired, to ensure sufficient patient follow-up. 18F-FDG with a radiochemical purity of 95% was provided. The following image is from a person with very few, small lung mets (ACC) and asthma/chronic bronchitis. Python code to visualize the annotation boxes on top of the DICOM images can be downloaded here.Two deep learning researchers used the images and the corresponding annotation files to train several well-known detection models which resulted in a maximum a posteriori probability (MAP) of around 0.87 on the validation set. Each study comprised one CT volume, one PET volume and fused PET and CT images: the CT resolution was 512 × 512 pixels at 1mm × 1mm, the PET resolution was 200 × 200 pixels at 4.07mm × 4.07mm, with a slice thickness and an interslice distance of 1mm. Incidental pulmonary nodules are commonly seen on computed tomography (CT) studies that include the lungs. The reconstructions were made in 2mm-slice-thick and lung settings. Questions may be directed to help@cancerimagingarchive.net.

Patients with Names/IDs containing the letter 'A' were diagnosed with Adenocarcinoma, 'B' with Small Cell Carcinoma, 'E' with Large Cell Carcinoma, and 'G' with Squamous Cell Carcinoma. The accompanying data  are survival data (status: dead or alive, survival time in months) and pathological stage (TNM). The RIDER Lung PET-CT collection was shared to facilitate the RIDER PET/CT subgroup activities. Only TLC (inspiration) scans are required for analysis. TCIA maintains a list of publications which leverage TCIA data. To distinguish studies with the same NLST PID, the NLST CT screening year (T0, T1, or T2) is inserted in a DICOM … The image annotations are saved as XML files in PASCAL VOC format, which can be parsed using the PASCAL Development Toolkit:  https://pypi.org/project/pascal-voc-tools/. Eight subjects were removed from the dataset because the submitting site determined that they required further medical examinations to make an accurate diagnosis.
