Nuclear imaging modalities for cardiac amyloidosis

Area of Science:

• Nuclear medicine
• Cardiology
• Amyloidosis research

Background:

• Amyloidosis is a disease of protein deposition in organs.
• Cardiac amyloidosis can cause heart failure and arrhythmias.
• Early diagnosis and monitoring are crucial for managing cardiac amyloidosis.

Purpose of the Study:

• To review current nuclear imaging modalities for detecting cardiac amyloid.
• To discuss the role of amyloid-specific tracers in diagnosis and disease monitoring.
• To highlight the potential of scintigraphy in managing cardiac amyloidosis.

Main Methods:

• Review of nuclear imaging techniques for cardiac amyloid detection.
• Discussion of amyloid-specific tracers used in planar imaging and SPECT.
• Examination of current investigational tracers for cardiac amyloid.

Main Results:

• Scintigraphy offers a noninvasive approach for cardiac amyloid detection.
• Amyloid-specific tracers show promise in distinguishing cardiac amyloid types.
• Nuclear imaging can help track disease burden in cardiac amyloidosis.

Conclusions:

• Nuclear imaging, particularly with specific tracers, is valuable for cardiac amyloidosis.
• Further development of approved cardiac amyloid tracers is needed.
• This review summarizes current nuclear imaging strategies for cardiac amyloid detection.
