Summary

Prone single photon emission tomography (SPET) offers comparable breast cancer detection to planar scintimammography. SPET provides better localization and characterization, making it a viable alternative for reduced imaging time.

Area of Science:

  • Nuclear Medicine
  • Medical Imaging
  • Oncology

Background:

  • Accurate breast cancer detection is crucial for effective treatment.
  • Planar scintimammography is a common imaging technique.
  • Evaluating advanced imaging modalities like SPET is essential.

Purpose of the Study:

  • To compare the diagnostic accuracy of prone single photon emission tomography (SPET) with planar scintimammography for suspected breast cancer.
  • To assess the localization and characterization capabilities of prone SPET.

Main Methods:

  • 24 patients with suspected breast cancer underwent both prone planar scintimammography and prone SPET.
  • 99Tcm-MIBI was used as the radiotracer.
  • Imaging was performed using a specially designed couch with different cushion inserts.

Main Results:

  • Both techniques showed high agreement (96%) in detecting breast cancer.
  • Planar imaging detected all histologically proven cancers.
  • Prone SPET demonstrated superior localization and characterization, despite missing one small ductal cancer due to reconstruction artifacts.

Conclusions:

  • Prone SPET provides similar results to prone planar imaging and can be used as an alternative when reduced acquisition time is desired.
  • Prone SPET offers improved localization and characterization of breast cancers.
  • Caution is advised when interpreting SPET scans of small tumors near the heart due to potential reconstruction artifacts.
