  • Rest-study in Myocardial Perfusion

Study (MPS) only when required

  • Benefits

– Reduce patient radiation exposure – Saving resources for the clinic

  • camera time
  • staff time for technologists and physicians

Nuclear Medicine Technologists determine the need for a rest study 1.Education of technologists 2.Clinical evaluation and comparison with physicians 3.Implementation of New Routine

New Routine

MPS protocol

  • Ergometer or Adenosine stress
  • Tc-99m Tetrofosmin
  • Siemens E-cam
  • Gated SPECT
  • Attenuation correction

Step 1: Education of technologists

Training

  • 82 cases with explanations;

– Why ”need” or ”no need” for a rest study Test

  • 20 cases
  • Maximum 1 ”mistake” was accepted
  • All technologists passed the test

Step 2: Clinical evaluation and comparison with physicians

  • Technologists

– Review the stress MPS images – Classify as ”Rest – No Rest” – Call the physican

  • Physician decide ”Rest – No Rest”
  • 130 consecutive cases
  • 96% agreement

Step 3: Implementation of New Routine

  • Based on the good results from Step 1+2
  • Implementation of the New Routine in

November 2011

Methods

  • Evaluation after implementation
  • Differences in frequency of rest studies

performed before and after implementation of the New Routine?

  • Study periods

– Before: Jan – Oct 2011 – After: Nov 2011 – Mar 2012

Results

  • Before “New Routine”

– 1 141 stress MPS – Rest MPS required in 641 (56.2%)

  • After “New Routine”

– 553 stress MPS – Rest MPS required in 312 (56.4%)

  • No statistically significant difference

Conclusion

  • Properly trained technologists are able to

decide whether a rest study is required

  • r not
  • Better effectiveness in our department
  • Both technologists and physicians are

satisfied with the new routine
