Effect of glyceryl trinitrate and clevidipine administration on CT angiogram findings in dogs undergoing prostatic artery embolization for prostatic carcinoma.
PLoS One
December 2024
Department of Surgical and Radiological Sciences, From the University of California-Davis, School of Veterinary Medicine, Davis, Davis, California, United States of America.
Objectives: The primary aim of this study was to evaluate the effects of vasodilator administration on CT angiography (CTA) prostatic artery diameter and peak opacification in dogs with prostatic carcinoma prior to prostatic artery embolization (PAE).
Materials And Methods: A prospective clinical trial was performed. Ten dogs with naturally occurring prostatic carcinoma and no evidence of cardiovascular disease were enrolled.
High volume-rate echocardiography for simultaneous imaging of electromechanical activation and cardiac strain of the whole heart in a single heartbeat in humans.
PLoS One
December 2024
Department of Radiology, Columbia University, New York, NY, United States of America.
Background: Imaging both electrical and mechanical cardiac function can better characterize cardiac disease and improve patient care. Currently, there is no noninvasive technique that can simultaneously image both electrical and mechanical function of the whole heart at the point of care. Here, our aim is to demonstrate that high volume-rate echocardiography can simultaneously map cardiac electromechanical activation and end-systolic cardiac strain of the whole heart in a single heartbeat.

Transthyretin amyloid cardiomyopathy (ATTR-CM) is becoming increasingly recognized with the aging population, advancements in understanding of disease pathobiology and the potential benefits of emerging therapies. Bone scintigraphy, including Tc-labeled pyrophosphate scintigraphy, is currently considered the first-line modality for identifying ATTR-CM. Therefore, it is important to increase the preset probability using inexpensive and simple tests including echocardiography.

December 2024
Department of Neurosurgery, Saitama Sekishinkai Hospital, 2-37-20 Irumagawa, Sayama, Saitama, 350-1305, Japan.
Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.
Assessing Acute Pericarditis with T1 Mapping: A Supportive Contrast-Free CMR Marker.
Tomography
November 2024
Department of Radiology, Azienda Ospedaliero Universitaria (A.O.U.), di Cagliari-Polo di Monserrato s.s. 554 Monserrato, 09045 Cagliari, Italy.
Objective: The purpose of this study was to explore the impact of pericardial T1 mapping as a potential supportive non-contrast cardiovascular magnetic resonance (CMR) parameter in the diagnosis of acute pericarditis. Additionally, we investigated the relationship between T1 mapping values in acute pericarditis patients and their demographic data, cardiovascular risk factors, clinical parameters, cardiac biomarkers, and cardiac function.
Method: This retrospective study included CMR scans in 35 consecutive patients with acute pericarditis (26 males, 45.
