Document Summary
Ct exam review: spatial resolution, temporal resolution, das speed. Individual reconstruction: volume reconstruction, filtered back reconstruction, deconvolution filter use, how does ir technique function, noise is removed from image by using a target model for comparison to acquired image. 20-30: 40-50, beam hardening can be problematic when imaging the posterior fossa. Initial contrast enhanced images of the adrenals are generally acquired at what phase: washed out (delayed, non contrast, arterial, portal venous, which window setting is used to demonstrate subtle liver lesions. In a patient experiencing renal colic, intensity of pain is always proportional to the size of the stone (that is the larger the stone the greater the pain): true, false. Identify typical symptoms of renal colic (select all that are correct): nausea, fever, mcburney"s sign, unable to move due to pain, unable to lie still due to pain. Eliminate streak artifacts from prosthetic devices: allow for good reformations, even in the presence of patient motion.
