Evaluation of systolic and diastolic heart function

Area of Science:

• Cardiology
• Medical Imaging
• Diagnostic Techniques

Background:

• Cardiac function evaluation is a key area of cardiovascular research.
• Conventional methods like angiography and ultrasound are evolving for assessing systolic and diastolic function.
• Advanced imaging modalities are increasingly explored for detailed cardiac assessment.

Purpose of the Study:

• To review the application of advanced imaging techniques for cardiac function assessment.
• To highlight the capabilities of ultrafast CT and MR imaging in evaluating heart function.
• To discuss the potential limitations of these technologies in routine clinical practice.

Main Methods:

• Review of 1990s literature on cardiac function evaluation.
• Analysis of contrast angiography, cardiac ultrasound, and radionuclide angiography applications.
• Evaluation of ultrafast CT for ventricular volume and ejection fraction quantification.
• Assessment of spin-echo and cine MR imaging for global and regional function estimation.

Main Results:

• Ultrafast CT accurately quantitates ventricular volumes and ejection fraction.
• Spin-echo and cine MR imaging provide precise estimates of global and regional ventricular function.
• Conventional modalities are being adapted for enhanced systolic and diastolic function assessment.

Conclusions:

• Advanced imaging techniques like ultrafast CT and MR imaging offer significant advancements in evaluating cardiac function.
• These sophisticated modalities provide accurate assessments of both systolic and diastolic heart function.
• The high cost of advanced imaging may limit their widespread adoption for routine systolic function assessment.
