Magnetic resonance (MR) imaging was performed in seven asymptomatic volunteers and 17 patients with clinical and radiologic evidence of sacroiliitis. MR imaging findings were compared with those at computed tomography (CT) to determine the MR imaging

The experience with CR systems gained at the three institutions described in this report demonstrates numerous advantages over the conventional screen-film system. These include: (1) a reduction in the radiation exposure delivered to the patient (25%

Computed radiography is a 2K x 2K x 10 bit digital radiographic system that replaces the film-screen combination with a photo-stimulable phosphor plate. The advantages of this relatively new technology include linear detector response, improved detec

Fifty-six radiographs of nondisplaced or minimally displaced fractures of the extremities and an equal number of studies with normal findings were selected and digitized to produce spatial resolution varying from 5.75 to 0.72 line pairs per millimete

A study was conducted on the use of an irreversible compression technique, Fourier quantization, to reduce the amount of digital data needed for an image. The effect of image compression was studied in radiographs obtained to diagnose subperiosteal b

Hungry animals drink extremely large quantities of water when they are intermittently fed small amounts of food. Are these animals motivated to drink for long durations or to ingest large volumes of fluid, or both? This question was studied by restri
