In a hurry? Make sure you know
- Reasoning and urgency of requesting imaging
- Renal function and allergies/previous reactions to contrast agents
- IV cannula sizes and locations
What history should JMOs know/collect?
- Brief presenting complaint and background
- List of differentials and how will the requested imaging help to confirm/exclude/define
- How clinically urgent is the result of this study? How will it change management?
- Recent past imaging and any adverse situations (eg. contrast allergy, claustrophobia, pacemakers)
What examination and investigations should JMOs perform/order?
- General appearance: Is this patient critically unwell? Will they survive the trip to the scanner?
- Salient examination findings: anything to help lend context to the reporter
- Body habitus: approximate height and weight
- IV cannulation: knowing the size/location/patency of cannulas for contrast-studies (large bore cannulas in the cubital fossa for certain studies eg. CTPA or CTCA)
- Bloods: creatinine and eGFR (baseline and recent)
What additional information would impress you?
- Awareness of the limitations of various studies and radiation safety issues
What are common mistakes/omissions made by JMOs?
- Not introducing yourself! It helps the radiologist to know what team you’re on or what level you are (everybody is a little nicer to interns)
- Not having a clear question to ask, ie. Let’s scan them to see what we’ll find
- “My registrar/consultant told me to get it” – if you’re unsure of the reasoning, clarify the necessity of this study with your seniors (it might get them to think twice about it too!)
- Not knowing details of recent past studies (this includes from other facilities/private)
- Taking an unstable/potentially unstable patient to radiology
