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.

Low levels of ‘organizational readiness’ could be holding back lung cancer screening programs

Willingness to change among radiologists and staff members (rather than leadership) has the biggest impact on lung cancer screening success, public health researchers reported Monday.

Risk model helps radiologists predict whether patients will experience contrast-associated injury after CT

The study represents the largest and most comprehensive investigation of contrast-associated acute kidney injury in patients with cancer.

Physical activity is linked to smaller brain bleeds, new CT data reveal

The research, published in Stroke and Vascular Neurology, suggests that just four hours of physical activity per week can reduce the significance of a brain bleed.

New data suggest that the burden of atherosclerosis on imaging might not be as indicative of major cardiovascular events as a person’s age and sex.

Nearly 90% of significant incidental findings on lung cancer screenings are considered reportable

These findings highlight a need for more stringent and standardized reporting guidelines relative to incidental findings, authors of the new study suggested.
