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.

New algorithm is twice as accurate at predicting stroke timing compared to the standard of care

Determining stroke onset is critical for management, as there is a small window of time for initiating treatment that can inhibit damage.

New protocol addresses contrast allergies in patients with suspected stroke

In patients with suspected stroke, contrast allergies present a significant dilemma, as contrast-enhanced imaging is often used to guide treatment decisions.

Clinical decision support significantly reduces use of CT for pulmonary embolism

Across  340,000 hospital admissions, there was a 7.4% decrease in CTPA use after referrers started consulting CDS, experts write in JACR

Non-enhancing asymmetries on contrast-enhanced mammography

Is additional imaging necessary for non-enhancing asymmetries on contrast-enhanced mammograms?

Patients with asymmetries on CEM typically are recalled for additional views, ultrasound and occasionally MRI. But the extra workup might not be necessary.
