The imaging community had more to cheer May 7 when the NIH announced the appointment of Dr. Roderic I. Pettigrew as the first permanent director of the National Institute of Biomedical Imaging and Bioengineering. Pettigrew's background in radiology and engineering makes him an ideal candidate for this NIH division, which addresses a wide range of biomedical technologies. Currently the director of Emory University's Center for MR Research, Pettigrew holds a doctorate from the Massachusetts Institute of Technology's department of nuclear engineering in applied radiation physics. He is also the immediate past chair of the diagnostic imaging study section at the Center for Scientific Review at NIH--the section that reviews grant applications to develop and evaluate new imaging technology, including instrumentation and software for producing, evaluating, storing, and transmitting images.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
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.
