Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...

MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...
Time-of-flight MRA at the level of the Circle of Willis. Magnetic resonance angiography ( MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels.

When a business charges a fee for a form of payment, whether in person, online or by phone, it’s called a surcharge. Credit card surcharges are applied when you use your credit card to make a ...
Photon-counting computed tomography ( PCCT) is a form of X-ray computed tomography (CT) in which X-rays are detected using a photon-counting detector (PCD) which registers the interactions of individual photons. By keeping track of the deposited energy in each interaction, the detector pixels of a PCD each record an approximate energy spectrum ...
The payment card interchange fee and merchant discount antitrust litigation is a United States class-action lawsuit filed in 2005 by merchants and trade associations against Visa, Mastercard, and numerous financial institutions that issue payment cards.
