New MRI Algorithm Cuts Scan Time by Two-Thirds
A far quicker MRI scan is on the horizon. A new algorithm developed by MIT’s Research Laboratory of Electronics cuts the imaging time by two-thirds, though they’re still working on the back end processing time. Authors of the research, which is scheduled for publication in the journal Magnetic Resonance in Medicine, say that a 45-minute scan can be done in 15 minutes without compromising much of the quality.
MRI Technique Promises Easier Way to Diagnose Alzheimer’s Disease
Researchers just found what they said is a cheaper and safer way to diagnose and track Alzheimer’s disease, using arterial spin labeling (ASL), a magnetic resonance imaging (MRI) technique. University of Pennsylvania’s Perelman School of Medicine researchers published twice on the technique this month, in Neurology, the American Academy of Neurology’s journal, and Alzheimer’s Disease and Dementia: the Journal of the Alzheimer’s Association.
MRI Not Quite There for Lymph Node Diagnosis in Breast Cancer
Magnetic resonance imaging’s accuracy in detecting cancer in the lymph nodes of newly diagnosed breast cancer patients is nothing to sniff at – 80 percent with diffusion-weighted MRI and 85 percent with axial T1-weighted MRI, Canadian researchers have reported. But it’s not quite high enough to skip a lymph node dissection, according to a study published online Dec. 5 in the journal Radiology.
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.
