MRI CAMRT Exam Questions With Complete Solution Is SNR proportional or inversely proportional to voxel volume -Correct Answer-Proportional 3 fields used in MRI -Correct Answer--static magnetic field -TVMF (gradient field) -RF field 3 main types of magnets used -Correct Answer--Superconducting (most common_ -Resistive -Permanent FDA limits for the 3 fields in MRI -Correct Answer-Static field: 2T TVMF: 3T/s RF field: - does not cause an increase in temperature of more than .5 deg...

MRI CAMRT: Pathology Exam solved 100% Abscess (brain): definition and imaging appearance on T1, T2, CE, and DWI -Correct Answer-Collection of pus. Mass effect and extensive surrounding edema. T1: hypointense to grey matter T2: hyperintense to grey matter with surrounding edema. CE MRI: ring-like enhancement DWI shows an abscess having a high DWI signal with corresponding low signal on the ADC map. Avascular Necrosis (AVN) -Correct Answer-T1: necrotic area is hypointense T2: hyperint...

Phase mismapping: Appearance - correct answer -AKA ghosting. produces replications of moving anatomy across the image in the phase direction. Usually occurs from anatomy that moves periodically (respirations, blood flow, swallowing, eye movement). Is phase mismapping/ghosting more or less apparent further from the source? - correct answer -Less apparent. What is the calculation for separation between ghosts? - correct answer -S(p)= scan time (TR, phase matrix, NEX) divided by the p...
