The gap between the last injection and the first delayed image is built into the tracers, not into the department. How to fill it with studies that image immediately, and the five places a nuclear medicine list actually breaks down.
Nuclear medicine RFQ checklist (TXT)
An idle camera can reflect the timing of uptake and delayed imaging rather than a lack of demand. Measure the complete patient pathway before treating utilisation as a reason to add staff, marketing or another detector.
Tracer biology and the approved clinical protocol define acceptable imaging windows. They vary by study and patient; early and delayed bone imaging, for example, answer different questions. Build the booking template around authorised protocols rather than a single fixed waiting interval.
So the working day has a shape. Injections cluster early, delayed imaging clusters late morning and afternoon, and between the two there is a window during which the camera has nothing booked. The window is not waste. It is only waste if nothing is put in it.
Some studies image from the moment of injection or within minutes of it. Those belong in the gap, and building the weekly template around that single idea recovers most of the lost capacity.
Dynamic studies such as renography or selected hepatobiliary and first-pass acquisitions may use early camera slots. Equilibrium gated blood-pool imaging is different from first-pass imaging and does not necessarily begin at injection. Allocate short-uptake, delayed-view and periodic QA work according to the protocol and required preparation.
Model activity availability using calibration times, decay, preparation limits and in-use expiry. Schedule within the clinical priorities and patient requirements; the highest activity should not automatically determine the first appointment. A written tracer-supply and contingency plan supports a workable list.
A template that works on paper fails in the same five places, and none of them is the camera.
Check communication and return times, injection-room capacity, inpatient transport, preparation, positioning, processing and downtime. An injection position requires an appropriate radiation-protection and clinical design, not merely a screened corner. Avoid assigning vulnerable or transport-dependent patients to expendable slots; build explicit contingency into the schedule.
Log representative weeks of patient arrival, preparation, injection, acquisition and reporting, with reasons for gaps or overruns. Use the measured bottleneck and variation to compare scheduling changes with additional equipment. No one week or fixed ten-minute threshold guarantees that a second camera is unnecessary.
