Siemens installs enhanced PET/CT
The latest version of Siemens' biograph is running at Hong Kong Baptist Hospital. The system features an advanced detector made from lutetium oxyorthosilicate (LSO), a scintillator whose high-speed properties allow shorter scan times and faster patient
The latest version of Siemens' biograph is running at Hong Kong Baptist Hospital. The system features an advanced detector made from lutetium oxyorthosilicate (LSO), a scintillator whose high-speed properties allow shorter scan times and faster patient throughput. PET and CT data can be acquired in 20 minutes or less on the LSO product, according to the company. The biograph is also available with detectors using a BGO (bismuth germanate) crystal. The first commercial installation of the BGO system was completed last fall at Memorial Sloan-Kettering Cancer Center in Manhattan.
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.
