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.

Radiologist-recommended testing for primary hyperparathyroidism improves diagnosis

Biochemical evaluation for patients with incidentally detected enlarged parathyroid glands can prompt earlier diagnosis, according to new data in the American Journal of Roentgenology

Incomplete neurovascular imaging work-ups to blame for subsequent stroke in patients with TIA

Up to 37% of patients presenting with transient ischemic attack do not receive a full neurovascular imaging work-up, according to new data published in the American Journal of Roentgenology. 

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.

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.
