ultrasound physicsSummary Echocardiography is one of the most valuable diagnostic tests for the evaluation of patients with suspected cardiovascular disease in the acute setting. Even though echocardiography has become more widely available, its performance and interpretation require practice and knowledge of...
Or maybe you are someone who is inwardlyterrifiedofmath and physics. Maybe you arealmost ready but just need to brush up on a few things. Have you beenworking for yearsand are finally ready to take the test? Who uses physics anyway?
In daily practice, medical history and physical examination are commonly coupled with anthropometric measurements for the diagnosis and management of patients with lymphatic diseases. Herein, considering the current progress of ultrasound imaging in accurately assessing the superficial soft tissues of the hum...
II. Background: Physics Resolution increases with frequency Penetration decreases with increased frequency Low frequency (1 MHz to 6 MHz): Deep Structures Transabdominal: 3.5 Mhz to 5.0 Mhz Transvaginal: 5.0 Mhz to 7.5 Mhz High Frequency (7 MHz to 13 MHz): Superficial Structures ...
First, prior to proceeding with a 3-arm randomized study, our study team spent a considerable amount of time launching a practical, yet HIPAA-compliant secure tele-communication system that could be applied not only to an education setting but also to a clinical practice. The most challenging ...
Upon graduation, are your residents trained well enough to practice at these volumes for the rest of their careers? (5) Finally, a question about peritoneal lavage. Are we abandoning a test with an extremely low false-negative rate (ie, DPL) for a test (ultrasound) with a significantly ...

Finally, intense acoustic pressure waves may induce a mean motion of the fluid. While the underlying physics are well documented (Lighthill1978; Duck et al.1998; Sarvazyan et al.2010), many textbooks give over-simplified and often contradictory explanations. There are three mechanisms that can le...
In clinical practice, PRP is often used for local administration, or the injured nerve may be wrapped with PRP membrane during operation, although the latter method may not achieve the therapeutic dose. Therefore, ultrasound-guided serial injection of PRP may be an accurate, widely applicable, nov...
