core radiology flashcards

Equipment Hourly Rates What is the activity limit for a Radiation area in Nucs? What is the maximum concentration of aluminum ion breakthrough allowed by the NRC in a technetium 99m generator? What is the (a) surface does limit and (b) exposure limit at 1 m for "yellow 2" packages? How much contrast you inject into the tibiotalar joint? Radiology Simplified (Apple Books) is the most accurate review of Core-relevant radiology physics anywhere. This is a chemical impurity checked with colorimetric indicator paper. Larmor frequency of H+ protons at 1T = 42MHz. radiation protection (68 cards) 2020-05-24 14 . Leakage radiation from x-ray house measured at 1m must not exceed what level? Study Flashcards On Core Radiology at Cram.com. Inverse square law = doubling the distance (SID) will quadruple the noise because energy that is twice as far away from the source will spread out over four times the area (resulting in 1/4th the intensity at the image receptor). Lower mA (5 instead of 500), same kVp (50-120), smaller focal spot (0.3mm). Quickly memorize the terms, phrases and much more. Phase encoding is done in the other shorter matrix dimension and dictates the number of repetitions needed to fill the remainder of the matrix. Start studying RADIOLOGY CORE. Both Compton scatter and photoelectric interaction are inversely proportional to the energy of the incident x-ray photons. What is the power used in (a) plain film radiography and (b) mammography? Learn vocabulary, terms, and more with flashcards, games, and other study tools. What is the best keV to maximize iodine contrast? Doubling magnetic field strength will result in a 4x increase in MR signal and 2x increase in MR noise, will result in T1 prolongation, and have no effect on T2. What is the activity limit for a Very High Radiation area in Nucs? Quickly memorize the terms, phrases and much more. Blank PET Scan = Daily (start with a blank slate). What dictates lateral resolution (two adjacent structures, perpendicular to the beam) in ultrasound? The Core is the closest resource that comes close to First Aid for USMLE. Cram.com makes it easy to get the grade you want! How much contrast do you inject into the elbow joint? Free flashcards to help memorize facts about CORE Radiology.

What is the relationship of tube voltage on Compton scatter and photoelectric interaction when the energy of the incident x-ray photons is above the k-edge of the material being imaged? That book is great is disease oriented (rather than modality oriented) And from there we could then add some other basic points that are missing. What type of radiation detector is used in dose calibrators? What is the primary source of patient heating in MRI? What is the recommended recall rate in mammography? I made a lot of flashcards directly from this book. Increased kVp results in a decreased linear attenuation coefficient and an increase in the half value layer needed to attenuate 50% of the x-ray beam. Sampling of the echo occurs during the frequency encoding steps and the number of samples per TR is dictated by one dimension of the matrix (typically the larger dimension because this can be done quickly). Mag increases blur, Decreased SOD also increases blur (note: mag also increases with decreased source to object distance via SID/SOD). How often is Field Uniformity of a gamma camera checked?
