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.

Long-term lung cancer survival rates see a 'dramatic' boost thanks to early detection initiatives

When lung cancer is caught in its early stages, long-term survival rates can reach 80% and higher, according to a new large-scale, 20-year international study presented at this year's RSNA meeting.

Caught early, lung cancer has 80% overall survivability at 20 years—100% for some tumor types—yet few individuals avail themselves of LDCT screening

New findings to be presented at RSNA confirm that lung cancer is highly curable as long as it’s diagnosed early, as is often the case with low-dose CT screenings.

Canadian radiologists push federal lawmakers to deal with ‘devastating impact’ of long waits for medical imaging

Radiologists from across Canada descended on Parliament Hill in Ottawa earlier this month to voice pressing concerns on behalf of medical-imaging patients and professionals.

Iodinated contrast use before, during and after COVID: Trends predict significant growth in demand
