| Quick summary The goal of a first on-call shift is not to solve every case alone. It is to prioritize appropriately, seek help promptly, and communicate clearly within a safe system. |

Much of the anxiety before a first on-call shift comes not from a lack of knowledge, but from uncertainty: Which examinations are you responsible for? When should you call a senior resident or attending radiologist? Will you issue a preliminary report or a final report? To whom should you communicate a critical finding, and how? Unless these questions have clear answers, even strong medical knowledge will not translate into a safe workflow.
The first goal of preparation is therefore not to memorize more diseases, but to make the boundaries of your institution's on-call system visible. The Medical Specialization Board of Türkiye structures radiology training around competencies and progressively increasing responsibilities; your on-call duties should likewise match your level of training, institutional protocols, and faculty supervision. [1]
Rather than learning the answers during the shift, turn them into a one-page local on-call card in advance. A card organized around roles and escalation phone numbers is more sustainable than one built around individual names.
Before the shift begins, confirm that you can log in to PACS and RIS, open prior studies, review image series using the appropriate windows and planes, and save a report. The diagnostic radiology life cycle described by the RCR emphasizes that safe care is a continuous process from referral and image acquisition through delivery of the result. [2] A technical failure at any point can prevent the result from reaching the patient even when the interpretation itself is correct.
Contrast safety involves more than knowing the types of reactions. Patient assessment, appropriately trained personnel, emergency equipment, medications, observation, and reporting processes must work together. The ACR Manual on Contrast Media is a comprehensive reference, but the steps you take on call are determined by your institution's current protocol and the training you have received. [3]
| Before the shift, make sure you personally locate the contrast reaction cart, identify the emergency call number and supervising physician, and learn which form or system is used to record an event. |

Do not undertake an intervention independently if you have not been trained to perform it. When in doubt, calling for senior support and emergency assistance without delay is not a sign of inadequacy; it is safe professional behavior.
One of the most time-consuming tasks on call is rewriting clinically simple but repetitive sentences. Your toolkit should contain safe wording that supports report structure and communication, rather than automated sentences that make a diagnosis for you.
Text expansion tools such as RadPhrases can speed up this wording, but every inserted statement must be reviewed by the physician against the images, the clinical question, and local reporting language. The product also makes clear that clinical control remains with the user. [4]
RCR reporting standards consider it fundamental that a report answer the clinical question, be clear enough to prompt appropriate care, and provide access to a second opinion when needed. [5]
Your threshold for asking for help should not be limited to situations in which you do not know the diagnosis. Early consultation is the safer choice when any of the following applies:
| A good on-call radiologist is not someone who knows everything alone, but someone who recognizes uncertainty early and involves the right person in time. |

At handover, it is not enough to state how many examinations remain. Separately communicate incomplete examinations, expected additional series, results that were communicated verbally but have not yet been documented, critical findings for which the clinician could not be reached, and cases awaiting senior review.
☐ I recorded the escalation chain and phone numbers.
☐ I tested PACS, RIS, and the dictation system.
☐ I know the critical finding notification process.
☐ I reviewed the contrast safety protocol and located the emergency equipment.
☐ I clarified responsibility for preliminary and final reports.
☐ I reviewed the local emergency imaging pathways.
☐ I learned the handover format.
☐ I prepared my own safe reporting templates.
