Optimising Radiation Dose Estimation: UNSCEAR DAP‐to‐ED Conversion in Uterine Artery Embolisation

Journal of Medical Radiation Sciences, EarlyView.
This study uses the conversion factors from the ‘UNSCEAR Global Survey on Medical Exposure: A User Manual’ to estimate radiation dose exposure for patients undergoing uterine artery embolisation. Estimating the effective dose provides interventional radiologists and interventional radiographers a better understanding of the stochastic risks associated ...

Imaging Characteristics of Persistent Carotid‐Vertebrobasilar Anastomoses Detected by Ultrasound

Journal of Ultrasound in Medicine, EarlyView.
In this case series, we aimed to evaluate the ultrasonic characteristics of 35 patients with persistent carotid‐vertebrobasilar anastomoses (PCVBA), a rare variant between the anterior and posterior cerebral circulation. Ultrasound detected seven (30.4%, 7/23) primitive trigeminal arteries (PTA), eight (100%, 8/8) primitive hypoglossal arteries (PHA ...

Nonrigid Image Registration in Digital Subtraction Angiography Using Multilevel B-Spline

BioMed Research International, 2013
We address the problem of motion artifact reduction in digital subtraction angiography (DSA) using image registration techniques. Most of registration algorithms proposed for application in DSA, have been designed for peripheral and cerebral angiography ...

Handheld Embedded Laser‐Diode Illumination Optoacoustic System for Real‐Time 3D Angiography of Deep Tissues

Laser &Photonics Reviews, EarlyView.
HELIOS is a handheld, cost‐effective optoacoustic imaging system integrating compact 915 nm laser diodes with a 256‐channel spherical array probe for volumetric human angiography. It delivers 1.8 mJ pulses at 400 Hz and allows for high‐resolution, real‐time imaging of deep tissues in a freehand mode for point‐of‐care applications, rivaling the ...

Advancing Localization Optoacoustic Tomography Using Experimentally‐Derived Effective Point Spread Functions

Laser &Photonics Reviews, EarlyView.
This study presents an improved technique for Localization Optoacoustic Tomography using experimentally‐derived effective point spread functions. The method significantly enhances sub‐pixel localization performance, with applicable potential to relatively under‐sampled scenarios and other imaging modalities, paving the way for new frontiers in super ...

Assessment of Double Outlet Left Ventricle in Pediatrics Using Transthoracic Echocardiography and Computed Tomographic Angiography

Pediatric Discovery, EarlyView.
The clinical manifestation of DOLV was atypical. TTE has a relatively high diagnostic accuracy for DOLV in pediatric, which is very valuable for its early detection. ABSTRACT Double outlet left ventricle (DOLV) is a rare congenital cardiac anomaly in which both great arteries originate entirely or predominantly from the morphologic left ventricle.

Effects of Shunt Position on the Prognosis of Transjugular Intrahepatic Portosystemic Shunt in Patients With Cirrhotic Esophagogastric Variceal Bleeding

Portal Hypertension &Cirrhosis, EarlyView.
The challenge of transjugular intrahepatic portosystemic shunt (TIPS) remains the puncture of the portal vein. Establishing an optimal shunt position in the left branch of the portal vein would be a better option for reducing the risk of postoperative hepatic encephalopathy and stent dysfunction.

Neuroprotective effects of remote limb ischemic preconditioning through enhanced cerebral blood flow via activation of the PI3K/AKT pathway in ischemic stroke

VIEW, EarlyView.
Stroke is a leading cause of death and disability worldwide, often due the inadequate restoration of cerebral blood flow following vascular recanalization. Our study demonstrates that a simple technique called RLIPC (remote limb ischemic preconditioning), which involves briefly restricting blood flow in a limb, protects the brain during a stroke by ...

Chinese Guidelines for Diagnosis and Treatment of Chronic Rhinosinusitis (2024)

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Chronic rhinosinusitis (CRS), a complex inflammatory disease with heterogeneous pathogenesis, demands evolving evidence‐based strategies. Since the 2018 Chinese guidelines and EPOS2020, international advances in CRS immunopathology and biologics have revolutionized therapeutic approaches, particularly through phenotype–endotype classification ...
