Radiologic Technologist Interview
Questions & Answers

PA projection: patient standing, posterior to the cassette or detector, shoulders internally rotated and pushed forward to reduce scapular overlay on the lung fields. Full inspiration before exposure — a deep breath lowers the diaphragm and expands the lung fields. Chin elevated to clear the superior thorax. Source-to-image distance 72 inches to reduce magnification of the heart. Check for rotation: the medial ends of the clavicles should be equidistant from the spinous processes. A rotated chest is a non-diagnostic chest.

ALARA principle: as low as reasonably achievable. Tight collimation to the area of interest. Correct kVp selection — higher kVp reduces patient dose but changes contrast. Use AEC (automatic exposure control) rather than manual technique for consistent results. Distance: doubling the distance reduces dose by 75% (inverse square law). Gonadal shielding where applicable. Do not repeat exposures for suboptimal positioning when the diagnostic information is still present — an imperfect image that answers the clinical question is better than a perfect image with double the dose.

Assess the cause of non-cooperation: pain, anxiety, cognitive impairment, or language barrier. For pain: position the patient as comfortably as possible within the constraints of the exam and work quickly. For anxiety: explain each step before you do it, maintain a calm demeanour, and allow a support person in the room where it does not compromise the examination. For the uncooperative patient who truly cannot hold still: immobilisation devices (where appropriate and within scope), modified positioning, or communicate to the ordering physician that the desired projection was not achievable and what was obtained instead.

Know the anatomy you are imaging well enough that an abnormality is visually obvious: pneumothorax on a chest X-ray, a foreign body on an acute abdomen, a fracture through the cortical margin of a bone. Radiologic technologists are not radiologists and do not diagnose — but you are obligated to bring a potentially critical finding to the radiologist's or ordering physician's attention immediately rather than sending the patient to the waiting room. "I want to make sure the radiologist sees this before the patient leaves" is the correct professional response.

Communicate with the ordering physician: is the contrast study essential given the allergy history, or can a non-contrast study answer the clinical question? If contrast is necessary: obtain the allergy history specifically (prior reaction type and severity, iodine allergy vs contrast allergy distinction). Pre-medication protocol (corticosteroids and antihistamines 13/7/1 hours before) for a history of prior contrast reaction. Have resuscitation equipment and staff available during the injection. Document the allergy, the pre-medication, and the informed consent. Never administer contrast to a patient with a known severe prior reaction without physician involvement.

Structure your answer as a 60-second professional narrative: where you have been (your background), what you have done (your strongest achievement), and where you are going (why this role). Lead with your most relevant experience, not your entire career history. End with why you are excited about this specific opportunity.

Choose a genuine weakness that you have actively worked to improve. The structure is: name the weakness → show self-awareness of its impact → describe the concrete step you took to address it → show the improvement. Never say "I work too hard" — interviewers recognise this as evasion and it damages your credibility.

Use the STAR method (Situation, Task, Action, Result) but add a fifth element: what you learned. Choose a real failure, not a disguised success. Show you can take responsibility without making excuses, and demonstrate that the lesson changed your behaviour in a specific, verifiable way.

Be honest but constructive. Acceptable reasons: seeking greater scope, new challenge, skills you can not develop in the current role, or company-level changes (restructuring, direction shift). Never speak negatively about your current employer or manager — it signals you will do the same to the prospective employer in future conversations.

Describe the conflict specifically, show that you sought to understand the other person's perspective, and explain the resolution approach you took. Interviewers are assessing your emotional intelligence and whether you escalate or resolve. Avoid stories where you were right and they were wrong — choose a story where both parties grew.

Describe your specific prioritisation system: impact × urgency matrix, stakeholder alignment, or a specific tool or process you use. Then give an example where you applied it under real pressure. Show that your system is systematic rather than reactive, and that you communicate proactively when priorities change.

Choose an achievement that is specific, measurable, and relevant to the role. Lead with the result ("I reduced our error rate by 40% in 90 days"), then explain the context, challenge, and what you specifically did that drove the result. Show your ownership and impact, not just your team's work.

Be honest about your ambitions while showing that this role is a genuine step in that direction — not a stopgap. Hiring managers want to invest in people who will grow with the organisation. Show that your 5-year goal requires the specific skills and experience this role provides, making your ambition an asset for both sides.

Research before the interview and make the answer specific: cite their product, a recent company development, something about their culture or team, or a professional aspect of this particular role that matches your goals. Generic answers ("I love your values") signal you did not do the research. Specific answers signal genuine interest.

Always have 3–5 questions prepared. Ask about the biggest challenge in this role, what success looks like in the first 90 days, how the team operates, and the interviewer's own experience at the company. Never ask about salary, benefits, or holidays in a first interview. Questions show interest, strategic thinking, and that you care enough to have done research.
