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 ...

Achieving robust labeling above the circle of Willis with vessel‐encoded arterial spin labeling

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To improve the robustness of noninvasive vessel‐selective perfusion imaging and angiography using vessel‐encoded arterial spin labeling (VEASL) when applied to complex vascular geometries, such as above the circle of Willis (CoW) in the brain.

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.

Accuracy of Length of Virtual Stents in Treatment of Intracranial Wide-Necked Aneurysms. [PDF]

, 2019
Background and purposePrecise stent deployment is important for successful treatment of intracranial aneurysms by stent-assisted coiling (SAC). We evaluated the accuracy of virtual stents generated using commercial stent planning software by comparing ...

The future of ischemic stroke: flow from prehospital neuroprotection to definitive reperfusion. [PDF]

, 2014
Recent advances in ischemic stroke enable a seamless transition of the patient flow from the prehospital setting to definitive reperfusion, without the arbitrary separation of therapeutic phases of ischemia based on time alone.

Utility of ABI and API Versus CTA to Identify Surgically Significant Arterial Injury After Lower Extremity Trauma in a LMIC

World Journal of Surgery, EarlyView.
South Africa faces a high burden of trauma‐related vascular injury. Prompt diagnosis and management are crucial to limit morbidity and mortality. Literature recommends a thorough vascular examination of at‐risk patients. Ankle brachial index (ABI) and arterial pressure index (API) are considered reliable screening tools for lower extremity vascular ...
