ARRT MRI

Case 001 (Patient Identification): In a busy hospital MRI department, what is the best identity verification action before entering Zone IV?

• AVerify at least two patient identifiers against the order and wristband.
• BRely on verbal confirmation from accompanying family only.
• CComplete scanning first, then confirm identity during documentation.
• DUse room number and exam schedule as the only identifiers.

Case 002 (Zone Access Control): During an outpatient MRI appointment, what is the best MRI zone-safety practice?

• AKeep Zone IV doors open for faster turnover.
• BUse verbal screening only for all MRI personnel and visitors.
• CAllow unscreened visitors into Zone IV when staff are present.
• DRestrict Zone III/IV access to properly screened and authorized individuals.

Case 003 (T1 Weighting): In a trauma-center MRI workflow, which parameter combination most strongly emphasizes T1 contrast?

• AShort TR and long TE.
• BLong TR and long TE.
• CShort TR and short TE.
• DLong TR and short TE.

Case 004 (Brain Protocol): During an evening shift with limited staffing, which sequence component is essential in many acute-brain MRI protocols?

• AOnly non-fat-suppressed proton density imaging.
• BDiffusion-weighted imaging with ADC assessment.
• COnly post-contrast T1 without baseline sequences.
• DLocalizers without diagnostic series.

Case 005 (MRI Screening): In a pediatric MRI scheduling block, which screening approach is most appropriate before the scan starts?

• AComplete and verify screening for implants, surgeries, and metal exposure before Zone IV…
• BAsk implant questions only when contrast is ordered.
• CRely on EHR problem list without interviewing the patient.
• DSkip the written screening form if the patient had MRI previously.

Case 006 (Projectile Hazard): In a neuro MRI service line, a ferromagnetic object is brought near the scanner room. What is the safest action?

• APlace it on the floor beside the magnet gantry.
• BContinue if no patient is currently in the bore.
• CBring it closer slowly to test magnetic attraction.
• DStop entry and remove the object from MRI controlled zones immediately.

Case 007 (T2 Weighting): During a same-day add-on exam, which parameter pattern best supports T2-weighted contrast?

• ALong TR and short TE.
• BShort TR and short TE.
• CLong TR and long TE.
• DShort TR and long TE.

Case 008 (Pituitary Imaging): In a high-volume academic imaging center, for pituitary evaluation, which protocol design is generally most appropriate?

• ALarge FOV body coil imaging without thin slices.
• BHigh-resolution thin-slice sellar imaging with protocol-appropriate contrast timing.
• CSingle sagittal localizer only.
• DReplace dedicated pituitary protocol with routine lumbar spine settings.

Case 009 (Claustrophobia Management): During a weekend emergency MRI schedule, the patient reports severe anxiety in confined spaces. What is the best first technologist action?

• AUse calm coaching, explain sequence timing, and apply protocol-approved comfort strategie…
• BCancel immediately without notifying ordering staff.
• CIncrease scan speed by skipping localization sequences.
• DProceed quickly without discussion to reduce anticipation time.

Case 010 (Static Field Awareness): In a community hospital MRI suite, which statement about the MRI static magnetic field is correct?

• AIt is disabled automatically whenever the table is out.
• BIt affects only implanted devices, not external equipment.
• CIt is present only during active pulse sequence acquisition.
• DIt is continuously present and creates persistent projectile risk.

Case 011 (FLAIR Use): In an oncology follow-up MRI visit, what is the main contrast goal of FLAIR imaging?

• AMaximize cortical bone signal for fracture detection.
• BSuppress fat to evaluate marrow edema primarily.
• CSuppress CSF signal to improve conspicuity of periventricular pathology.
• DEliminate all flow effects in vascular imaging.

Case 012 (IAC Protocol): During a contrast-enhanced protocol setup, for internal auditory canal evaluation, what is usually important for diagnostic quality?

• ALow-resolution body imaging planes only.
• BHigh-resolution thin-section sequences through temporal bone/IAC region.
• CSkip axial/coronal orientation planning entirely.
• DUse only abdominal protocol presets.

Case 013 (Gadolinium Risk Review): In a patient with prior surgery and implants, what should be verified before contrast administration per facility policy?

• ARelevant renal-risk history and required pre-contrast safety checks.
• BContrast lot number only, without patient-specific assessment.
• CPrior exam diagnosis only, without consent or screening review.
• DOnly patient age, because renal status is unrelated to contrast decisions.

Case 014 (RF Burn Prevention): During a motion-sensitive exam for pain, what setup adjustment best reduces RF burn risk?

• AIncrease SAR if image quality appears low.
• BUse all available coils even when not connected.
• CAllow cable loops and skin-to-skin contact to improve comfort.
• DPrevent conductive loops and pad skin contact points per protocol.

Case 015 (STIR Principle): In a claustrophobic patient scenario, what is the principal purpose of STIR in MRI protocols?

• AIncrease spatial resolution without time tradeoffs.
• BSuppress CSF signal for demyelinating disease.
• CSuppress fat signal for edema-sensitive imaging.
• DReplace diffusion imaging in acute stroke workups.
