Question

Fusion imaging in cardiac catheterization laboratory.

Hint:

Fusion imaging improves procedural accuracy and safety by combining different imaging techniques, making complex interventions easier to perform.

Answer 1

Fusion imaging combines multiple imaging modalities to improve the accuracy and safety of procedures in the cardiac catheterization laboratory. This technology integrates real-time fluoroscopy with other imaging techniques such as CT, MRI, and echocardiography.
Step 1: Benefits of Fusion Imaging:
1. Improved Precision: It enhances the visualization of complex coronary anatomy, making it easier to navigate catheters and stents during angioplasty or other interventions.
2. Reduced Radiation Exposure: By combining multiple imaging techniques, fusion imaging can reduce the need for prolonged fluoroscopy, thereby lowering radiation exposure to the patient and the medical team.
3. Enhanced Procedural Guidance: It allows for real-time guidance during procedures, helping physicians plan and execute interventions with greater accuracy and efficiency.
Step 2: Clinical Applications:
1. Coronary Artery Disease (CAD): Fusion imaging is useful in guiding interventions such as angioplasty and stenting in patients with CAD.
2. Congenital Heart Disease: It is also used to guide catheter-based interventions in patients with congenital heart disease, offering improved visualization of the vascular structures.
Step 3: Limitations:
1. Complexity of Setup: Fusion imaging systems require multiple modalities and expertise to operate effectively, which can be technically challenging.
2. Cost: The use of advanced imaging technologies increases the cost of procedures, limiting its availability in some settings.
