Imaging of atherosclerosis (Part II)

Area of Science:

• Cardiovascular Medicine
• Medical Imaging
• Diagnostic Techniques

Background:

• Atherosclerosis detection relies on various methods, including angiography, CT, and sonography.
• Traditional methods like angiography are invasive and unsuitable for asymptomatic individuals.
• Current morphological imaging techniques lack the ability to assess the functional status of atherosclerotic lesions.

Purpose of the Study:

• To review current functional diagnostic procedures for atherosclerosis.
• To evaluate the potential of advanced imaging techniques for early atherosclerosis detection.
• To highlight the role of functional imaging in understanding atherosclerosis progression.

Main Methods:

• Review of functional diagnostic procedures including scintigraphy (planar and SPECT), PET, and MRI.
• Comparison of functional methods with standard morphological techniques (angiography, CT, sonography).
• Analysis of preliminary evidence for radioisotopic techniques and MRI in early atherosclerosis imaging.

Main Results:

• Functional methods partially address the need for early atherosclerosis imaging.
• Radioisotopic techniques and MRI show potential for future elucidation of functional aspects.
• Existing functional methods are crucial for assessing the functional stage of atherosclerotic lesions.

Conclusions:

• Functional imaging techniques offer a complementary approach to morphological methods in atherosclerosis diagnosis.
• Advanced techniques like MRI and radioisotopic methods hold significant promise for future research and clinical application.
• Further research is needed to fully leverage the potential of functional imaging in managing atherosclerosis.
