Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

Study highlights CT findings that could mask lung cancer, leading to delayed diagnosis

For many patients with interstitial lung disease, cancer could go undetected for years, putting them at risk of disease progression that would require more extensive treatment.

Does BMI affect AI's accuracy when assessing CT scans?

AI is only as effective as the data it was trained on, and many datasets lack diversity in terms of patient body mass index.

Radiation exposure during imaging may be causing some pediatric cancer cases

Although the risk of developing cancer due to radiation exposure during medical imaging is small, there are clear associations between the two.

AI model reduces false positives on lung cancer CT scans

AI model nearly halves false positive rates for lung cancer CT screenings

Reducing false positives could decrease the frequency of unnecessary procedures, lower the associated costs and also ease patient anxiety concerning CT results.
