AI algorithm predicts Alzheimer's disease progression
February 19, 2019 -- An artificial intelligence (AI) algorithm can predict the progression of Alzheimer's disease by analyzing a combination of demographic and neuroimaging data, as well as information on cerebrospinal fluid and cognitive performance biomarkers, according to research published online February 13 in Scientific Reports.  Discuss
TexLab AI algorithm predicts ovarian cancer survival
February 15, 2019 -- By analyzing tumor characteristics such as structure, shape, and size, an artificial intelligence (AI) algorithm called TexLab 2.0 is able to predict which patients with ovarian cancer have the best prognosis. The prediction can then be used to direct patient therapy, according to an article published online February 15 in Nature Communications.  Discuss
Live from HIMSS 2019: The PACSman on AI and radiology
February 14, 2019 -- ORLANDO, FL - What needs to happen next before artificial intelligence (AI) can become a routine clinical tool in radiology? We talked to the PACSman, aka Michael J. Cannavo, about the intersection of AI and radiology at this week's Healthcare Information and Management Systems Society (HIMSS) meeting.  Discuss
AI singles out high-risk prostate cancer on mpMRI
February 8, 2019 -- Working with radiomics data on multiparametric MRI (mpMRI) scans, an artificial intelligence (AI) algorithm was able to distinguish between low-risk and high-risk prostate cancer more accurately than the current risk assessment approach used by radiologists, according to research published online February 7 in Scientific Reports.  Discuss
AI may predict lymph node metastasis in gastric cancer
February 8, 2019 -- The combination of artificial intelligence (AI) and radiomics features on CT images can outperform current methods for preoperatively predicting lymph node metastasis from gastric cancer, according to research published online February 4 in the Journal of the American College of Radiology.  Discuss
PET, AI show women's brains age differently than men's
February 7, 2019 -- Are women's brains really that much different from men's? In a word, yes. A machine-learning algorithm applied to data from multiparametric PET brain scans showed that women's brains are more "youthful" than those of men of the same age, according to a study published February 4 in the Proceedings of the National Academy of Sciences.  Discuss
AI can predict breast cancer molecular subtypes on MRI
February 6, 2019 -- Can an artificial intelligence (AI) algorithm identify the molecular subtype of breast cancer from breast MRI as accurately as genetic testing? Not yet, but a deep-learning model offers considerable potential, according to research published online January 31 in the Journal of Digital Imaging.  Discuss
Russian AI detects lung cancer on CT in 20 seconds
February 4, 2019 -- Researchers from Russia have developed an artificial intelligence (AI) program called Doctor AI-zimov that is capable of identifying and marking lung nodules -- some as small as 2 mm -- on CT scans in under 20 seconds.  Discuss
Funding for imaging AI companies tops $1.2B
February 1, 2019 -- Investor money continues to surge into start-up companies that are developing artificial intelligence (AI) solutions for medical imaging. But the nature of those investments is beginning to change as the AI market develops, according to Simon Harris of U.K. market research firm Signify Research.  Discuss
