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.

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.

New data suggest clinicians should think twice before foregoing contrast-enhanced imaging

The new data highlight a potential pitfall of unenhanced CT scans on patients presenting to emergency departments with acute pain—an inaccurate workup.

spinal cord injury on CT of patient with degenerative spinal changes

CTs of adults with degenerative changes should be met with high suspicion for spinal cord injury following trauma

This is increasingly recognized as a potentially underreported phenomenon, accounting for roughly half of all such injuries in certain populations.

Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
