Priority Description
1. P1 High probability of potentially life threatening condition
2. P2 High probability of condition potentially causing significant long term harm
3. P3 Possibility of potentially life threatening condition
4. P4 Possibility of condition potentially causing significant long term harm
5. P5 Unlikely to be life threatening or cause significant long term harm

Protocol code When to use
?Ca 2Wk ? Cancer 2ww – use as normal – scan to be scheduled within 2 weeks
Urgent Urgent – use as normal – scan to be scheduled within 4 weeks
COVID – Semi Urgent Examination needs performing during next few months
Routine Do not use during Covid pandemic
COVID P5 Cancel Examination is P5 exam and will be cancelled and re refer back to clinician
Cancel Examination to be cancelled due to non-justification of examination only ( not due to COVID)
On hold Use as normal

All routine are reclassified as above.

Renal stones?

CT Kidneys Ureter Bladder (non-contrast, low dose)

1.5 mm B30f, 1.2 mm increment.

No contrast

CT KUB


Follow up of VUJ stones

Limited CT bladder (non-contrast)

1.5 mm B30f, 1.2 mm increment.

No contrast

CT bladder


Cause of PUJ obstruction, not from stones

Pre, arterial and delayed - Change to pre + combined dual bolus angio and delayed?

1.5 mm B30f, 1.2 mm increment.

 

CT IVU but renal angio YZT


Haematuria:


Asymptomatic Microscopic haematuria Low risk (<40 years, no other risk factor)

If persistent

Renal tract US, Plain KUB BUT In persistent haematuria CT IVU

1.5 mm B30f, 1.2 mm increment.

CT IVU - Pre, bolus 5 minutes before, repeat bolus and 90 second scan

Symptomatic microscopic haematuria Low risk (<40 years, no other risk factor)

X

CT KUB non contrast , low dose

1.5 mm B30f, 1.2 mm increment.

1.5 mm B30f, 1.2 mm increment.

CT IVU - Pre, bolus 5 minutes before, repeat bolus and 90 second scan

CT IVU


Abnormality on ultrasound for characterisation Follow up of Bosniak cysts (2F and greater)

X

Pre contrast and 90 second (nephrographic)

Or Pre, arterial and 90 seconds

I have been asked to add both of these and have been protocolling some as one, some as another. If you have a way to differentiate, please let me know

1.5 mm B30f, 1.2 mm increment.

Pre-contrast and 90 seconds

CT CAP + C + art renal


 

Potential live donor

CT pre, renal angiogram and venous phase + topogram delayed

1.5 mm B30f, 1.2 mm increment.

Bolus track arterial and pv. Timings? HU threshold?

 

Potential transplant recipient

Non contrast abdomen and pelvis

Old split bolus was 50 ml at 1.6 ml/s, pause 10 seconds, 50 ml at 4 ml/s, 50 ml flush at 4 ml/s Now, just non con to look for iliac calcific atheroma

Non con abdo pelvis
