As AI becomes ingrained in radiology practice, it is proving useful for multiple tasks. This month’s e-News Exclusive details an exciting development in cancer classification. Researchers at the Mallinckrodt Institute have developed an algorithm that can identify brain cancer types by looking at MRI scans.

Deep Learning Classifies Brain Tumors With Single MRI
A team of researchers at Washington University School of Medicine has developed a deep learning model that is capable of classifying a brain tumor as one of six common types, using a single 3D MRI scan, according to a study published in Radiology: Artificial Intelligence.
“This is the first study to address the most common intracranial tumors and to directly determine the tumor class or the absence of tumor from a 3D MRI volume,” says Satrajit Chakrabarty, MS, a doctoral student under the direction of Aristeidis Sotiras, PhD, and Daniel Marcus, PhD, in the Mallinckrodt Institute of Radiology’s Computational Imaging Lab at Washington University School of Medicine in St. Louis.
The six most common intracranial tumor types are high-grade glioma, low-grade glioma, brain metastases, meningioma, pituitary adenoma, and acoustic neuroma. Each was documented through histopathology, which requires surgically removing tissue from the site of a suspected cancer and examining it under a microscope. According to Chakrabarty, machine and deep learning approaches using MRI data could potentially automate the detection and classification of brain tumors.
“Noninvasive MRI may be used as a complement, or in some cases, as an alternative to histopathologic examination,” Chakrabarty says.

Cryo-EM Imaging Lends Insight Into Elusive RNA Chemistry
California’s SLAC National Accelerator Laboratory reports that cryogenic electron microscopy, or cryo-EM, provides a long-sought glimpse into the innermost workings of RNA. The applications range from a better understanding of COVID-19 to the reassessment of the evolution of life itself, according to findings published in Nature.
AI-Enhanced Technology Ramps Up Koala Conservation Efforts
Marshalling drones equipped with cutting-edge infrared, conservationists at Australia’s Queensland University of Technology announce an AI hub to create a “census” of the indigenous koala population. The effort, they say, will streamline rescue efforts for the beloved marsupials and other Outback wildlife during the impending brushfire season.
Ultrasound Proves Effective in Chimeric Antigen Receptor T Cell Therapy
CAR-T cell therapy can be significantly enhanced with the use of ultrasound to remotely trigger cancer-killing immune cells, according to researchers at UC San Diego. The new technique eliminates the toxic side effects long associated with the treatment of cancerous tumors, as detailed in a study in Nature Biomedical Engineering.
‘Secrets of Stonehenge’: Imaging Offers Answers About Revered UK Landmark
Using a variety of imaging modalities, personnel from the United Kingdom’s University of Brighton have postulated why Stonehenge has remained intact for some 5,000 years: a durable, interlocking mosaic of quartz crystals has rendered the structure resistant to erosion and other forces of time. Additional details are available in PLoS One. |

“This statement is an important reminder that patients may receive substantial clinical benefit from imaging exams. While we want to see prudent use of radiation in medical imaging, and many of our scientific members are working on means of reducing overall patient radiation dose, we believe it is an important matter of patient safety and clinical care that decisions on the use of imaging exams be made solely on the presenting clinical need and not on prior radiation dose.”
— James Dobbins, PhD, president of the American Association of Physicists in Medicine, regarding a joint statement issued in conjunction with ACR and the Health Physics Society regarding cumulative radiation dose limits for patient imaging |
