Phase-contrast imaging - Phase-contrast imaging - or more casually, High Resolution (HR) imaging - is a method of imaging in Transmission Electron Microscopy (TEM). The ability to image using phase contrast is one of the key elements which differentiates Transmission Electron Microscopy from conventional optical (light) microscopy, and is due to the fact that the atoms in a material diffract electrons as the electrons pass through it (the relative phases of the ...
Contrast enhanced ultrasound - Contrast enhanced ultrasound (CEU) is the application of ultrasound contrast agents to traditional medical sonography. Ultrasound contrast agents are gas-filled microbubbles that are administered intravenously to the systemic circulation.
Assay sensitivity - Assay sensitivity is a property of a clinical trial defined as the ability to distinguish an effective treatment from a less effective or ineffective treatment.
