Longitudinal cerebral perfusion in presymptomatic genetic frontotemporal dementia: GENFI results
DISCUSSION: Cerebral perfusion is a potential biomarker for assessing genetic FTD and its genetic subgroups prior to symptom onset.HIGHLIGHTS: Gray matter perfusion declines in at-risk genetic frontotemporal dementia (FTD). Regional perfusion decline differs between at-risk genetic FTD subgroups . Hypoperfusion in the left thalamus is common across all presymptomatic groups. Converters exhibit greater right frontal hypoperfusion than non-converters past their expected conversion date. Cerebral hypoperfusion is a potential early biomarker of genetic FTD.PMID:38623902 | DOI:10.1002/alz.13750 (Source: The Journal of Alzheimers Association)

SPINNED: Simulation-based physics-informed neural network for deconvolution of dynamic susceptibility contrast MRI perfusion data
CONCLUSION: These results support that the proposed SPINNED method can be a good alternative to the existing methods for resolving the deconvolution problem in DSC MRI. The proposed method does not require any separate ground-truth measurement for training and offers additional benefits of quick processing time and coverage of diverse clinical scenarios. Consequently, it will contribute to more reliable, accurate, and rapid diagnoses in clinical applications compared with the previous methods including those based on supervised learning.PMID:38623911 | DOI:10.1002/mrm.30095 (Source: Magnetic Resonance in Medicine)

Isolated Fragments of Intact Microvessels: Tissue Vascularization, Modeling, and Therapeutics
ABSTRACTThe microvasculature is integral to nearly every tissue in the body, providing not only perfusion to and from the tissue, but also homing sites for immune cells, cellular niches for tissue dynamics, and cooperative interactions with other tissue elements. As a microtissue itself, the microvasculature is a composite of multiple cell types exquisitely organized into structures (individual vessel segments and extensive vessel networks) capable of considerable dynamics and plasticity. Consequently, it has been challenging to include a functional microvasculature in assembled or fabricated tissues. Isolated fragments of...

Post-ductal coarctation of aorta aneurysm repair in adult via left antero-axillary thoracotomy with antegrade cerebral perfusion —a case series
We describe our experience in managing three such patients through antero-lateral thoracotomy with antegrade cerebral perfusion. We have found this technique helpful in treating aneurysms of the distal aortic arch or proximal descending thoracic aorta. (Source: Indian Journal of Thoracic and Cardiovascular Surgery)

ESR Essentials: imaging in stable chest pain – practice recommendations by ESCR
AbstractStable chest pain is a common symptom with multiple potential causes. Non-invasive imaging has an important role in diagnosis and guiding management through the assessment of coronary stenoses, atherosclerotic plaque, myocardial ischaemia or infarction, and cardiac function. Computed tomography (CT) provides the anatomical evaluation of coronary artery disease (CAD) with the assessment of stenosis, plaque type and plaque burden, with additional functional information available from CT fractional flow reserve (FFR) or CT myocardial perfusion imaging. Stress magnetic resonance imaging, nuclear stress myocardial perfu...

Is Kinesio taping acutely effective for peripheral tissue perfusion in women with mild to moderate chronic venous insufficiency? A randomized controlled trial
Objective To evaluate the acute effect of Kinesio Taping ® (KT) on peripheral tissue perfusion in women with chronic venous insufficiency (CVI). Methods: This randomized, double-blind controlled trial included 59 women with mild to moderate CVI. They were randomized to a control group (n = 23; 54.08 ± 9.04 years) and KT group (n = 36; 55.87 ± 9.97 years). Near-infrared spectroscopy was positioned in the medial gastrocnemius muscle for assessment of resting tissue perfusion 48 h after the first day of evaluation and after placement of the Kinesio Taping® tape.

Cerebellar blood perfusion is a diagnostic, but not a prognostic, marker for parkinsonian-dominant type multiple system atrophy.
Multiple system atrophy (MSA) is clinically characterized by various neurological symptoms. According to the diagnostic criteria, MSA is classified into parkinsonian-dominant type (MSA-P) or cerebellar ataxia-dominant type (MSA-C) based on the predominant signs displayed. Recently, N-isopropyl-p-[123I] iodoamphetamine (123I-IMP) single-photon emission computed tomography (SPECT), a radiological examination evaluating brain perfusion, has been successful in detecting cerebellar hypoperfusion in MSA-P patients, demonstrating its utility in the early detection of cerebellar dysfunction.

Cuboid Bone for Distal Radius Reconstruction: An Anatomical Cadaver Study
Conclusion The CB presented reasonable anatomical similarities with the DR and a long and consistent pedicle with an adequate blood supply observed during ICG injection.
Clinical Relevance This study supports the possibility of using the CB as a vascularized bone transfer for autologous reconstruction of the articular surface of the DR. Further study is warranted.

Multiparametric ultrasound as a new concept of assessment of liver tissue damage
World J Gastroenterol. 2024 Mar 28;30(12):1663-1669. doi: 10.3748/wjg.v30.i12.1663.ABSTRACTLiver disease accounts for approximately 2 million deaths per year worldwide. All chronic liver diseases (CLDs), whether of toxic, genetic, autoimmune, or infectious origin, undergo typical histological changes in the structure of the tissue. These changes may include the accumulation of extracellular matrix material, fats, triglycerides, or tissue scarring. Noninvasive methods for diagnosing CLD, such as conventional B-mode ultrasound (US), play a significant role in diagnosis. Doppler US, when coupled with B-mode US, can be helpful...
