Research finds technology combining molecular imaging and CT can cut down on patient dose by limiting the number of CT scans per imaging study Molecular imaging is effective for providing information about disease processes, and today's hybrid imaging systems have additional computed tomography (CT) technology on board for alignment and imaging structures. While this addition increases the amount of radiation dose a patient receives, research presented at the Society of Nuclear...

New molecular imaging technique compensates for breathing and heartbeat to deliver highest-quality images of the heart A development in 4D image reconstruction compensates for blurring caused by the beating of the heart, say researchers at the Society of Nuclear Medicine's 59th Annual Meeting. The new method provides sharper-than-ever images of cardiac function to help pinpoint heart defects for better diagnoses and treatment. Cardiovascular disease is the number one killer across the...

High-contrast, High-resolution CT Scans Possible At Low Dose

Soft body tissue can now be imaged with incredible detail using X-rays thanks to a new low dose CT-scan technique Scientists have developed an X-ray imaging method that could drastically improve the contrast of computed tomography (CT) scans whilst reducing the radiation dose deposited during the scan. The new method is based on the combination of the high contrast obtained by an X-ray technique known as grating interferometry with the three-dimensional capabilities of CT. It is also...

Peter B. Bach, M.D., of the Memorial Sloan-Kettering Cancer Center, New York, and colleagues conducted a systematic review to examine the evidence regarding the benefits and harms of low-dose computerized tomography (LDCT) screening for lung cancer, which is the leading cause of cancer death. "Most patients are diagnosed with advanced disease, resulting in a very low 5-year survival rate," the authors write. "Renewed enthusiasm for lung screening arose with the advent of LDCT imaging, which...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
