The joint guidelines indicate that "the brain death or death by neurologic criteria evaluation is, first and foremost, based ...

Brain death determination sits at the fraught intersection of critical-care medicine, ethics, and organ-donation logistics.

Background In contrast to conventional CT perfusion (CTP) imaging, flat panel detector CT perfusion (FD-CTP) imaging can be acquired directly in the angiosuite. Objective To evaluate time-resolved ...

GE HealthCare GEHC recently unveiled new advancements in precision cardiac care at the 2025 SNMMI annual meeting in New ...

Objective To assess the feasibility of quantitative myocardial perfusion imaging (MPI) in acute myocardial infarction (AMI), using multi-row detector CT (MDCT) with a model-based deconvolution method.

Background The purpose of this study was to evaluate the correlation between a novel angiographic score for collaterals and CT perfusion (CTP) parameters in patients undergoing endovascular treatment ...

Methods: Patients with 50%–99% sICAS in the anterior circulation were enrolled. Cerebral perfusion measures were obtained from computed tomography (CT) perfusion images, including infarct core volumes ...

The observed sensitivity and specificity measures for computed tomography perfusion and computed tomography angiography as an ...

Attenuation correction is now recommended to improve the diagnostic accuracy of myocardial perfusion SPECT (1). Attenuation maps are usually obtained with a transmission scan from a radioactive line ...

251397 Introduction: Hybrid SPECT/CT systems are critical for myocardial perfusion imaging (MPI), particularly through the implementation of CT-based attenuation correction (AC). While primarily used ...
