CT Registry Review (MIC) Questions and Answers Rated 100% In order for an x-ray photon to be measured it must: 1. enter the detector chamber 2. be absorbed by the detector material 3. be converted to a measurable event *ANS* 1,2,3 Which system component converts the projection attenuation data into the proper digital form for the array processor? *ANS* analog-to-digital converter Which of the following is NOT a function of a PACS system? a. reconstruction of the image from the raw d...

Cognitive neuroscience Midterm Exam with complete solutions A patient who makes no pronunciation errors when singing but many errors when speaking is an example of a(n) A. double dissociation B. association C. classical single dissociation D. strong single dissociation - answerClassical Single Dissociation A situation in which a patient is impaired on a particular task (task a) but relatively spared on another task (task b). - answerSingle Dissociation Patient performs normally on Task...

What is TMS (transcranial magnetic stimulation)? - correct answer a *non-invasive* technique use to create a virtual cortical *lesion* What does TMS involve? - correct answer [small, brief, localised lesions] they are temporary and don't cause harm How is TMS applied? - correct answer Externally, using a coil placed on the scalp that produces a rapi...

TMS - -A change in electric current in a wire generates a magnetic field -Magnetic field induces a secondary electric current in neurons below the stimulation site -Induced electric current creates a change in membrane potentials of neurons -Depolarization: increased rate of AP's, excitation -Hyperpolarization: decreased rate of AP's inhibition -Magnetic field is unimpeded by the skin and skull -Delivers a magnetic pulse that lasts for less than a millisecond -Effects on cortex can last...

What is TMS? - correct answer A "non-invasive" technique to create virtual cortical "lesions" Why have studies on patients with real lesions informed cognitive science for a long time? - correct answer They allow studying what patients can't do anymore Phineas Gage () - correct answer An American railroad construction worker who suffered a seriou...

TMS - technique for inducing virtual lesions or temporarily excite neurons Principles - rapidly changing magnetic fields => induction of electric current Method - - a coil is placed near the participant's head - very brief, very large pulse of current is run through - induction of strong, transient magnetic field - transient magnetic field induces current in nearby conductors (e.g. neurons in the brain) Can Cause - - activation: response of peripheral muscles after stimulation - inhib...

What is TMS? - correct answer Non-invasive technique to create virtual cortical lesions Provide an example of how studies on patients with real lesions have informed cognitive science - correct answer Phineas Gage: an American railroad construction worker who suffered a serious head injury by an iron rod piercing his head and frontal cortex leading to severe personality changes Why do we not alway...

What is TMS? - correct answer Non-invasive technique to create virtual, reversible cortical lesions that temporarily interrupt cognitive function in order to understand the function of specific brain regions Why do we use TMS, rather than patients? - correct answer Not enough patients with circumscribed lesions to study all cognitive functions Lesions in single, specialized areas are rare Recov...

is the proper sequencing of ICD-10-CM and CPT codes for outpt catheterization? - ANSWERS,I25.10 (Atherosclerotic heart disease of native coronary artery without angina pectoris) 93458 (Catheter placement in coronary artery(s) for coronary angiography, incl intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation with left heart catheterization including intraprocedural injection(s) for left ventriculography, when performed 65yo pt adm w/pain and loos...
