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.

Lung cancer screenings are proven to save lives, but disparities remain, experts discover

Non-white individuals and people living in less educated, lower income areas are more likely to receive an advanced lung cancer diagnosis, such as stage 4 disease.

Radiologists should be mindful of extracolonic findings on CTC scans of cancer patients

Extracolonic findings observed on computed tomography colonography scans of cancer patients might identify undetected malignancies more often than previously thought, according to a new study in Clinical Imaging.

Lung damage appears to persist one year after COVID-19 pneumonia, new CT study reveals

It is unclear if imaging abnormalities represent persistent scarring, and whether they may regress over time or lead to pulmonary fibrosis, experts wrote in Radiology.

CT-based radiomics nomogram accurately predicts colorectal cancer prognosis

The study's findings could be used to help clinicians guide treatment decisions for CRC patients, experts suggested in Academic Radiology.

Imaging suggests blood clots are more common in COVID than pneumonia

In a recent study, venous thromboembolisms were detected in those with COVID via multiple imaging modalities at a rate of 16.3% compared to 9.2% in individuals with CAP.
