Summary
Mixed reality (MxR) navigation for common femoral artery (CFA) access shows potential for improved safety. However, current workflows require simplification for practical clinical use.
Area of Science:
- Medical Imaging
- Interventional Radiology
- Mixed Reality Technology
Background:
- Common femoral artery (CFA) access is crucial for vascular interventions.
- Current ultrasound-guided techniques have limitations in precision.
- Mixed reality (MxR) offers novel visualization possibilities for medical procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of three MxR-navigated workflows for CFA access.
- To compare navigated techniques against conventional sonography-guided access.
- To identify areas for improvement in MxR-guided procedural navigation.
Main Methods:
- Phantom model study involving 160 punctures by 10 operators (experts and non-experts).
- Comparison of three MxR workflows against a sonography-guided control group.
- Positional errors quantified using cone-beam computed tomography.
Main Results:
- MxR-navigated techniques resulted in significantly shorter distances from needle entry to the femoral head's mid-level compared to the control.
- Three-dimensional visualization demonstrated potential to enhance CFA access safety.
- Navigated workflows exhibited infrastructural complexity, limited usability, and high costs.
Conclusions:
- MxR-guided navigation is a promising adjunct for safe CFA access.
- Future MxR development should focus on reducing workflow complexity and cost.
- Pragmatic registration and instrument tracking methods are needed for wider adoption.

01:17Veins of Upper Limbs
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

01:20Anatomy of Blood Vessels
The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta, have...

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
