Evaluation of time-resolved whole brain flat panel detector perfusion imaging using RAPID ANGIO in patients with acute stroke: comparison with CT perfusion imaging. [PDF]

open access: yes, 2022
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 whole brain FD-CTP imaging and assess clinically

Spatio-Temporal Modelling of Perfusion Cardiovascular MRI [PDF]

open access: yes, 2010
Myocardial perfusion MRI provides valuable insight into how coronary artery and microvascular diseases affect myocardial tissue. Stenosis in a coronary vessel leads to reduced maximum blood flow (MBF), but collaterals may secure the blood supply of the ...

Abstract Number ‐ 46: Automated Magnetic Resonance Perfusion Imaging in the Management of Delayed Cerebral Ischemia: A Pilot Study

open access: yesStroke: Vascular and Interventional Neurology, 2023
Introduction Inadequate perfusion secondary to changes in vascular narrowing and breakdown of cerebral autoregulation is thought to be a major contributor to delayed cerebral ischemia (DCI).

Perfusion in ENT imaging

open access: yesDiagnostic and Interventional Imaging, 2013
Perfusion MRI is an essential part of characterizing salivary gland tumors. The shape of the curves can provide a guide as to the type of lesion: benign (ascending plateau) or malignant (descending plateau), and can also occasionally strongly suggest a histological type such as a Warthin tumor (intense, rapid contrast enhancement with washout>30 ...

Laser speckle contrast imaging compared with indocyanine green in renal perfusion of a porcine model

open access: yesCurrent Urology, 2023
. Background. When viewed under near-infrared light, indocyanine green (ICG) signal for kidney perfusion can be utilized in partial nephrectomy. Laser speckle contrast imaging (LSCI) uses coherent light to detect perfusion during real-time laparoscopic ...

Is there a role for perfusion imaging in assessing treatment response following ablative therapy of small renal masses—A systematic review

open access: yesEuropean Journal of Radiology Open, 2018
Aims: Ablation therapies are an innovative nephron-sparing alternative to radical nephrectomy for early stage renal cancers, although determination of treatment success is challenging.

Myocardial perfusion imaging [PDF]

open access: yesHeart, 2000
Non-invasive images of the myocardium that reflect myocardial perfusion can be obtained either by using conventional nuclear medicine radiopharmaceuticals and cameras or by positron emission tomography (PET). This review will focus on myocardial perfusion imaging using conventional approaches; a subsequent article in this series will focus on PET ...

Stroke penumbra defined by an MRI-based oxygen challenge technique: 1. validation using [14C]2-deoxyglucose autoradiography [PDF]

open access: yes, 2011
Accurate identification of ischemic penumbra will improve stroke patient selection for reperfusion therapies and clinical trials. Current magnetic resonance imaging (MRI) techniques have limitations and lack validation.
