New CT rule-out examination cuts patient x-ray exposure
High radiation exposure has been the bogeyman keeping the cardiac CT triple rule-out exam for chest pain from widespread application.
High radiation exposure has been the bogeyman keeping the cardiac CT triple rule-out exam for chest pain from widespread application. The use of radiation dose reduction techniques addresses that concern.
Dr. Kevin Takakuwa and colleagues at Thomas Jefferson University reviewed data from 267 consecutive patients who underwent triple rule-out cardiac CT angiography after presenting to the emergency roon with symptoms of acute coronary syndrome. Ninety-five patients underwent the triple rule-out CTA protocol with tube current modulation, and 172 did so without it. Investigators found that patients undergoing triple rule-out without tube current modulation received average effective radiation doses of 18 mSv. Those getting the exam with tube current modulation, however, had effective radiation doses reduced by more than 50% without image quality loss. Findings were published in the American Journal of Roentgenology (2009;192[4]:866-872).
Seven Takeaways from New CT and MRI Guidelines for Ovarian Cancer Staging
January 20th 2025In an update of previous guidelines from the European Society of Urogenital Radiology published in 2010, a 21-expert panel offered consensus recommendations on the utility of CT, MRI and PET-CT in the staging and follow-up imaging for patients with ovarian cancer.
Four Strategies to Address the Tipping Point in Radiology
January 17th 2025In order to flip the script on the impact of the radiology workforce shortage, radiology groups and practices need to make sound investments in technologies and leverage partnerships to mitigate gaps in coverage and maximize workflow efficiencies.
CT Study Reveals Key Indicators for Angiolymphatic Invasion in Non-Small Cell Lung Cancer
January 15th 2025In computed tomography (CT) scans for patients with solid non-small cell lung cancer (NSCLC) < 30 mm, emerging research suggests the lollipop sign is associated with a greater than fourfold likelihood of angiolymphatic invasion.
