Temporal averaging angiographic reconstructions from whole-brain CT perfusion for the detection of vasospasm.

Purpose: The aim of this study is to evaluate the image quality and diagnostic performance of angiographic images reconstructed from whole-brain CT perfusion (CTP) using temporal averaging compared to CT angiography (CTA) for the detection of vasospasm.

Materials And Methods: 39 CT studies in 28 consecutive patients who underwent brain CTA with CTP for suspected vasospasm between September 2020 and May 2021 were retrospectively evaluated. The image quality of these two vascular imaging techniques was assessed either quantitatively (image noise, vascular enhancement, signal-to-noise (SNR) and contrast-to-noise (CNR) ratios,) and qualitatively (4 criteria assessed on a 5-point scale).

Hyperacute simultaneous cardiocerebral infarction related to floating thrombus in the ascending aorta: a case report.

Background: Ascending aortic thrombus has been reported in several case reports, often revealed by peripheral embolization, but very few revealed by cardiocerebral infarction. Moreover, there is no defined treatment strategy.

Case Summary: An 83-year-old woman was admitted to our intensive care unit for concurrent acute myocardial infarction (AMI) and acute stroke, both with the presence of an embolism.

Prenatal developmental toxicity studies on diundecyl and ditridecyl phthalates in Sprague-Dawley rats.

This study evaluates the developmental toxicity of two high molecular weight dialkyl phthalate esters, diundecyl phthalate (DUDP) and ditridecyl phthalate (DTDP). Sprague-Dawley rats were administered 0, 0.25, 0.

Prenatal developmental toxicity studies on di-n-heptyl and di-n-octyl phthalates in Sprague-Dawley rats.

This study evaluates the developmental toxicity of two dialkyl phthalate esters, di-n-heptyl phthalate (DHPP) and di-n-octyl (DnOP) phthalate, which have straight-alkyl side chains of seven and eight carbons, respectively. Sprague-Dawley rats were administered 0, 0.25, 0.

Developmental toxic potential of di-n-propyl phthalate administered orally to rats.

The objective of this study was to evaluate the developmental toxic potential of di-n-propyl phthalate (DnPP) in rats. Pregnant Sprague-Dawley rats were given DnPP at doses of 0 (olive oil), 0.5, 1 and 1.
