Implication

Review demonstrates how perfluorochemical gases extend microbubble survival in blood circulation, indicating improved diagnostic accuracy for cardiovascular diseases and solid tumors.

Key Points

Review the development of perfluorochemical-stabilized microbubbles as injectable contrast agents in diagnostic ultrasonography and explore their expanding clinical and therapeutic roles.
Evaluated the biophysical mechanisms governing microbubble dissolution, such as Laplace pressure, blood pressure, and acoustic energy.
Assessed clinically approved formulations incorporating gases such as octafluoropropane (C3F8), sulfur hexafluoride (SF6), and nitrogen stabilized with perfluorohexane (C6F14).
Surveyed tissue-suppression imaging technologies and emerging diagnostic applications, including targeted molecular imaging and ultrasound-mediated drug delivery.
Replacing air with fluorocarbon vapor extends microbubble survival in the bloodstream from seconds to several minutes, overcoming rapid dissolution from Laplace pressure.
Selective tissue-suppression imaging techniques paired with stabilized microbubbles significantly boost ultrasound signal contrast, enabling clearer visualization of cardiovascular lesions and solid tumors.
Stabilized microbubbles show therapeutic potential as vehicles for site-specific gene delivery and ultrasound-triggered drug release.
