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:

Breast cancer is a leading cause of cancer risk for women globally.
Early detection through mammography screening significantly reduces mortality rates.
Current manual reading of mammograms can lead to false-positive results, causing patient distress and increased healthcare costs.

Purpose of the Study:

To introduce NL-Breast-Screening, a novel, publicly available dataset specifically designed for developing automated breast cancer detection methods.
To support the advancement of automated reading in population-based mammography screening programs.

Main Methods:

The NL-Breast-Screening dataset comprises 5997 mammography exams from a Canadian provincial screening program.
Each exam includes four standard views and is biopsy-confirmed.
The dataset identifies cases with false-positive readings by radiologists.

Main Results:

The dataset provides a valuable resource for machine learning model development in breast cancer screening.
It specifically addresses the need for data derived from real-world population screening initiatives.

Conclusions:

NL-Breast-Screening facilitates the development of more efficient and accurate automated mammography reading systems.
This resource aims to enhance early breast cancer detection and reduce the impact of false-positive findings in screening programs.
