Computed Tomography

Around the web

Many new imaging solutions were on display at the world's largest health informatics conference, held at McCormick Place in Chicago.

Radiologist David Gruen, MD, discusses some of the overarching themes from the Healthcare Information Management Systems Society's annual meeting.

End-users of various radiology IT systems offer their assessment of the software in the annual KLAS Research 2023 Best in KLAS report.

Dual source CT scanners shown to expedite treatment in emergency settings

Dual source CT scanners can eliminate the need for beta blockers to control heart rates during coronary CTA exams.

Top, baseline axial unenhanced chest CT obtained 6 days before the first positive PCR test. Bottom, chest CT scan 4 days later shows the size increase of the lesion (arrow). Image courtesy of RSNA. #COVID #SARSCoV2

How effective are chest CT severity scores in managing COVID?

While the studies on these systems have proven them to be effective in diagnosing and treating COVID in specific cohorts, the varying settings in which they were used can make it difficult to derive definitive conclusions on their efficacy.

Serial transverse CT scans in a 65-year-old man with severe COVID-19 from 23-days after infection to 2-year follow up. The newest followup images on the right showed presence of subtle, subpleural honeycombing at the same area (black arrows). Image courtesy of Radiology. #longcovid #covidlonghauler #lungdamagecovid

Severe COVID patients continue to evidence lung abnormalities 2 years after initial infection

Scans on these patients show a combination of fibrosis, thickening, honeycombing, cystic changes and dilation of the bronchi, among other imaging features.

Risk model-based lung cancer screening more cost-effective than USPSTF guidelines

Using risk model-based strategies to determine who should undergo low-dose CT lung cancer screening is more cost effective than current U.S. Preventive Services Task Force guidelines.

CTA-based radiomics can reliably estimate time since stroke onset

Radiomics features could be especially useful for determining TSS in scenarios where clinical data is lacking or unreliable, such as when patients have altered mental status.

Photon counting cuts CTA contrast dosage 25%

Not only does the low-volume contrast protocol preserve supplies, it also protects patients who might be vulnerable to adverse reactions and/or side effects from contrast use.

PHOTO GALLERY: What does fetal medical imaging look like?

This is a clinical photo gallery of fetal imaging that explains what all can be seen on medical imaging, how sex is determined, how measurements are used to track the development of a baby.

A 'clear lack of adherence' in imaging guidelines is impacting lung cancer survival rates

A study published in the January issue of the Journal of Nuclear Medicine reveals that nearly half of Medicare patients with NSCLC in the United States do not complete recommended FDG PET/CT scans prior to treatment.
