BNMS Molybdenum Supply Update July

We are advised that the supply of Molybdenum 99 to the United Kingdom during July 2010 is likely to be severely constrained by the reduction in reactor capacity. This is the continuing result of the planned and unplanned repairs and maintenance of a number of  reactors.
Early advice indicates that all departments will experience a shortfall in supply and it is possible that some departments will receive less than 50% of their requested activity to maintain a full clinical service.

This was discussed by BNMS Council on 29 June and endorsed by Dr Erika Denton, National Clinical Lead for Diagnostic Imaging, Department of Health.

Where a department has a significant shortfall it is recommended that priority is given to the following studies:  

1.Sentinel lymph nodes 
2.Paediatric studies 
3.Studies in which other imaging modalities are specifically contraindicated eg patients in renal failure where i.v. contrast may not be given for CT or MR 
4.Clinically urgency as determined by discussion between managing clinicians.

The previous advice on optimising Tc-99m usage and the use of Tl-201 for cardiac imaging is available on the website here 

We would strongly encourage you to inform us weekly of your supply and patient activity during this shortage. This should be through the generator update form here.

We are expecting that the situation will improve towards the end of July and that supplies will be restored from Chalk River later this year.

Environment Agency Briefing on Technetium 99m supply

The Environment Agency has produced a new briefing note in relation to the ongoing shortage of Technetium 99m generators. This confirms their previously published enforcement position but indicates that if permanent or semi permanent changes to deliveries are put in place then users should obtain appropriate variations to their registrations.

Molybdenum supply letter from Dr Gill Vivian - 16th October 2009

Dear Colleagues,

There are currently two substantial problems with Molybdenum supply:

  • One of our licensed distributors of radio-isotopes have gone into liquidation resulting in difficulty in transporting radiopharmaceuticals and generators this weekend;
  • GE are experiencing particular problems with generators this week.

Please let us know immediately of any problems you are facing this week.

We would also like you to include information on your current waiting lists and activity position as a national snapshot.

Kind regards
Dr Gill Vivian
President, British Nuclear Medicine Society.
