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.
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
