Technical Knowledge
In my previous role at a community hospital, physicians frequently asked me to choose the most appropriate modality for complex cases.
I needed to explain the key differences between CT and MRI to help the care team select the right study while considering patient safety and diagnostic yield.
I described that CT uses ionizing radiation to acquire fast cross‑sectional images, excels at evaluating bone, acute hemorrhage, and trauma, and is ideal for emergent situations. MRI, on the other hand, uses magnetic fields and radiofrequency pulses, provides superior soft‑tissue contrast, is radiation‑free, and is preferred for neurologic, musculoskeletal, and oncologic imaging when time permits. I also highlighted contraindications such as metal implants for MRI and renal function for contrast‑enhanced studies.
The team selected CT for a suspected intracranial bleed, leading to rapid diagnosis and treatment, and chose MRI for a follow‑up spinal assessment, providing detailed soft‑tissue information without radiation exposure.

A 55‑year‑old outpatient presented for a routine pre‑operative chest X‑ray.
My responsibility was to obtain a high‑quality postero‑anterior (PA) and lateral view while ensuring patient comfort and minimizing repeat exposures.
I greeted the patient, verified identity, and explained the procedure. I positioned the patient upright against the detector, instructed them to take a deep breath and hold it, ensured proper centering at the level of the clavicles, and used the appropriate exposure settings based on body habitus. After the PA image, I repositioned for the lateral view, confirming the patient’s arm placement to avoid superimposition, and repeated the breath‑hold technique.
Both images met radiologist quality standards on the first attempt, eliminating the need for retakes and keeping radiation dose as low as reasonably achievable (ALARA).

Patient Care
A 4‑year‑old was scheduled for a chest X‑ray after a recent cough, but became visibly upset in the waiting area.
I needed to calm the child, gain cooperation, and complete the exam without sedation or repeat exposures.
I knelt to the child's eye level, introduced myself, and used a friendly tone. I explained the machine as a 'big camera' that takes pictures of the inside. I let the child hold a favorite stuffed animal, demonstrated the breath‑hold using a balloon toy, and offered a small sticker reward after the scan. I also involved the parent, asking them to stay close and provide reassurance.
The child cooperated fully, the images were diagnostic on the first attempt, and the parent expressed gratitude for the gentle approach, reducing the likelihood of future anxiety.

A recent immigrant patient with limited English needed a contrast‑enhanced abdominal CT, but was nervous about the IV contrast and the procedure steps.
I had to ensure the patient understood the purpose, risks, and what to expect, using language they could comprehend, while adhering to consent policies.
I accessed a hospital‑approved Spanish translation card that outlined the procedure in simple terms. I also used visual aids showing the CT scanner and a diagram of the IV line. I spoke slowly, used gestures, and confirmed understanding by asking the patient to repeat key points. I documented the interpreter assistance in the record and obtained a signed consent form with the translated text.
The patient proceeded with the scan confidently, experienced no adverse reaction, and later thanked the team for the clear communication. The radiologist received high‑quality images without delay.

Safety & Compliance
During routine chest X‑rays, I noticed occasional repeat exposures due to positioning errors, raising dose concerns.
My goal was to reinforce ALARA principles and reduce unnecessary radiation for both patients and technologists.
I reviewed the department’s radiation safety policy, ensured proper use of lead aprons and thyroid shields, and calibrated the equipment daily. I implemented a checklist that included verifying patient size, selecting the lowest appropriate exposure settings, and confirming correct collimation before each exposure. I also educated staff on stepping back during exposures and using remote controls when possible.
Repeat rates dropped by 35%, average patient dose decreased by 12%, and a subsequent safety audit rated our unit as ‘exemplary’ for radiation protection.

During a routine quality‑control check, I discovered that the protective barrier on the CT scanner’s gantry was cracked, exposing the control console to stray radiation.
I needed to address the hazard immediately to protect staff and maintain compliance with safety regulations.
I stopped all non‑emergency scans, reported the issue to the biomedical engineering team, and documented the defect in the safety log. While awaiting repair, I arranged for a temporary lead barrier and reassigned urgent scans to an alternate scanner. I also communicated the situation to the radiology supervisor and updated the staff on the interim safety measures.
The equipment was repaired within 24 hours, no staff exposure incidents occurred, and the incident was recorded in the department’s safety audit, contributing to a zero‑incident rating for the quarter.

Professionalism
In a rapidly evolving field, I recognized the need to keep my knowledge up‑to‑date to provide optimal patient care.
My objective was to integrate new imaging techniques and best practices into daily workflow.
I subscribe to peer‑reviewed journals such as Radiology and the American Journal of Radiology, attend quarterly webinars hosted by the American Registry of Radiologic Technologists (ARRT), and participate in the hospital’s monthly imaging case conference. I also completed an online certification in advanced CT protocols last year and share key takeaways with my team during shift huddles.
My proactive learning enabled me to implement low‑dose CT protocols that reduced patient dose by 15% and improved image quality, earning recognition from the department head.

A radiologist once expressed frustration that my positioning for a lumbar spine X‑ray was inconsistent with his preferred protocol, leading to a delayed report.
I needed to resolve the disagreement while maintaining a professional relationship and ensuring patient throughput.
I scheduled a brief meeting with the radiologist after his shift, listened to his concerns, and reviewed the department’s official positioning guidelines together. I explained my rationale for the slight variation, citing patient comfort and reduced repeat rates. We agreed to adopt a hybrid approach and documented the updated protocol in the shared SOP folder. I also invited the radiologist to observe a few of my positioning sessions for mutual feedback.
The conflict was resolved amicably, repeat rates for lumbar spine studies dropped by 10%, and the radiologist praised the collaborative effort in a subsequent staff meeting.
