Study finds PET no better than SPECT

Positron emission tomography (PET) is no better than single-photon emission computed tomography (SPECT) in the evaluation of ischemic heart disease, according to a technology assessment published by ECRI.
The study, sponsored by the Plymouth Meeting, PA-based nonprofit group, concluded that PET images provide better contrast and spatial resolution than SPECT in assessments of myocardial blood flow and viability. The group found that the difference had little effect on clinicians' ability to diagnose coronary artery disease, however.
The study concluded that there is some question as to when PET's expense and clinical value justify its use over SPECT. The study was prepared by ECRI's Health Technology Assessment Information Service.
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.
