Imaging Studies III: Computed Tomography

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Background:

The National Cancer Institute's Quantitative Imaging Network (QIN) supports developing quantitative imaging methods and biomarkers for assessing tumor response in clinical trials.
A key QIN objective is fostering collaboration to establish best practices for cancer imaging data analysis.

Purpose of the Study:

To validate novel image analysis algorithms and biomarkers for therapy response assessment.
To enable the comparison and evaluation of algorithms and biomarkers using large, diverse datasets through analysis challenges.

Main Methods:

Conducting analysis competitions (challenges) within the QIN framework.
Leveraging The Cancer Imaging Archive (TCIA) for multisite data sharing of clinical images, including DICOM data.
Utilizing linked clinical, pathology, and ground truth data available in TCIA collections.

Main Results:

Demonstrated the feasibility of multisite sharing of clinical imaging data through the QIN-TCIA partnership.
Established a successful model for supporting algorithm and biomarker validation via data sharing and challenges.

Conclusions:

The TCIA-QIN collaboration provides essential resources for validating cancer imaging algorithms and biomarkers.
This partnership supports the translation of quantitative imaging methods into clinical practice for improved cancer patient care.
