Siemens to present new intraoperative MRI
Siemens Medical Systems this month announced an addition to its MRI product lineup for the upcoming Radiological Society of North America meeting. The work-in-progress device, OR Open, is an intraoperative MR unit that combines Siemens' open system
Siemens Medical Systems this month announced an addition to its MRI product lineup for the upcoming Radiological Society of North America meeting. The work-in-progress device, OR Open, is an intraoperative MR unit that combines Siemens' open system Magnetom Open Viva with a new table that enables surgeons to do interventional MRI procedures in an operating room suite.
The scanner's height-adjustable table swings out and can be tilted up and down, giving surgeons 360 access to patients and the ability to position patients' organs in a way comparable to routine surgery. OR Open allows surgery to be done close to the magnet, which eliminates the need to move patients once the procedure has begun. The table's position flexibility allows surgeons to use both the magnet and other imaging devices such as x-ray or ultrasound, according to Dr. Jonathan Lewin, director of MRI at University Hospitals of Cleveland, where Siemens has placed the first OR Open.
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.
