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.

pulsed radiofrequency for sciatica

Pulsed radiofrequency procedure could help patients avoid surgery for sciatica

In PRF procedures, a probe is used to intermittently apply energy directly to the dorsal root ganglia, which is often where pain and neurologic symptoms associated with sciatica originate.

2 years on, lung damage scant in COVID survivors who were ventilated

Most patients who received mechanical ventilation for COVID-19 at a busy European hospital not only survived but also showed no scarring or thickening on lung CT at two years post-discharge.

Many U.S. websites do not reflect updated lung cancer screening guidelines

Accurate information relative to personal risk is crucial for improving uptake of low-dose CT (LDCT) lung cancer screening, but new data indicate that many websites' content on the topic is out of date.

Neuroradiologists make more mistakes when facing these 3 scenarios

“These findings should be considered when designing workflow-related and other interventions seeking to reduce errors," experts wrote in AJR

Paltry use of CT for lung cancer screening persists across all payer types

The findings should serve as a call to action for radiologists to increase awareness about LDCT, experts contended.
