In 1982, the organizational units at the FDA that regulated medical devices and radiation-emitting products merged to form the Center for Devices and Radiological Health (CDRH). Former leaders of CDRH [15] Jeffrey Shuren, M.D., J.D., CDRH Director 2009 – 2024; Daniel Schultz M.D., CDRH Director 2004 – 2009
Flurpiridaz F-18 is a fluorine 18-labeled agent developed by Lantheus Medical Imaging for the diagnosis of coronary artery disease. [6]The efficacy and safety of flurpiridaz (18 F) were evaluated in two prospective, multicenter, open-label clinical studies in adults with either suspected CAD (Study 1: NCT03354273) or known or suspected CAD (Study 2: NCT01347710).

The original difference was that radiography fixed still images on film, whereas fluoroscopy provided live moving pictures that were not stored. However, modern radiography, CT, and fluoroscopy now use digital imaging with image analysis software and data storage and retrieval. Compared to other x-ray imaging modalities the source projects from ...
Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique.
Images can be produced from a variety of methods including: microscopy, imaging probes, and spectroscopy. Fluorescence itself, is a form of luminescence that results from matter emitting light of a certain wavelength after absorbing electromagnetic radiation. Molecules that re-emit light upon absorption of light are called fluorophores. [1] [2]
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. It is primarily performed by highly skilled and specialty trained gastroenterologists.
Fluorescence guided surgery (FGS), also called fluorescence image-guided surgery, or in the specific case of tumor resection, fluorescence guided resection, is a medical imaging technique used to detect fluorescently labelled structures during surgery. [1]
Currently Siemens and GE are the only companies to offer a fully integrated whole body and simultaneous acquisition PET-MRI system. The Siemens system (Biograph mMR) received a CE mark [19] and FDA approval [20] for customer purchase in 2011. The GE system (SIGNA PET/MR) received its 510K & CE mark in 2014. [citation needed]
