Radiologists should not only take their patients' history but perhaps also record their future travel plans. Apparently, individuals undergoing diagnostic or therapeutic nuclear medicine procedures can trip radiation detectors designed to catch terrorists smuggling radioactive material.
Radiologists should not only take their patients' history but perhaps also record their future travel plans. Apparently, individuals undergoing diagnostic or therapeutic nuclear medicine procedures can trip radiation detectors designed to catch terrorists smuggling radioactive material.
One man set off an alarm in a tunnel while riding a bus from New York to Atlantic City, NJ, a few years ago. In the 1980s, two people undergoing radionuclide therapy set off detectors in the White House.
But the potential for these false alarms is rising as portable radiation monitors proliferate and the number of nuclear medicine scans increases, Dr. Lionel Zuckier said at the 2004 RSNA meeting.
Zuckier and colleagues at the University of Medicine and Dentistry of New Jersey found that iodine-131 can trigger alarms up to three months after its administration; gallium-67 and thallium-201 up to 30 days; indium-111 up to 17 days; and technetium-99m and iodine-123 up to three days.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
Systematic Review: PET/MRI May be More Advantageous than PET/CT in Cancer Imaging
July 18th 2024While PET/MRI and PET/CT had comparable sensitivity for patient-level regional nodal metastases and lesion-level recurrence, the authors of a systematic review noted that PET/MRI had significantly higher accuracy in breast cancer and colorectal cancer staging.
The Reading Room: Racial and Ethnic Minorities, Cancer Screenings, and COVID-19
November 3rd 2020In this podcast episode, Dr. Shalom Kalnicki, from Montefiore and Albert Einstein College of Medicine, discusses the disparities minority patients face with cancer screenings and what can be done to increase access during the pandemic.
FDA Clears Enhanced Mobile CT System with High-Resolution Photon-Counting Technology
