Cancer patients want more information about medical imaging risk

A substantial gap exists between patient expectations and current practices for providing information about medical imaging tests that use radiation, according to a new study published online in the journal Radiology. Researchers said the findings highlight a need for better communication as medicine enters an era of patient-centered care.In recent years, there have been numerous reports in the media about potential risks of tests that use ionizing radiation. However, benefit-risk discussions about ionizing radiation from medical imaging are rare and seldom initiated by clinicians.For the new study, researchers from Memorial Sloan Kettering Cancer Center (MSKCC) in New York City analyzed over nine hours of transcribed conversations with 30 people who had undergone medical imaging exams to determine their understanding of the benefits and risks associated with various medical imaging procedures and their expectations regarding communication of those benefits and risks.

Cherenkov Effect improves radiation therapy for patients with cancer

The characteristic blue glow from a nuclear reactor is present in radiation therapy, too. Investigators from Dartmouth’s Norris Cotton Cancer Center, led by Brian W. Pogue, PhD, and PhD candidates Adam K. Glaser and Rongxiao Zhang, published in Physics in Medicine and Biology how the complex parts of the blue light known as the Cherenkov Effect can be measured and used in dosimetry to make therapies safer and more effective.”The beauty of using the light from the Cherenkov Effect for dosimetry is that it’s the only current method that can reveal dosimetric information completely non-invasively in water or tissue,” said Glaser.
