Utilizing post-imaging surveys to guide development of photoacoustic computed technology for breast imaging.

OBJECTIVE

Current breast imaging has limitations. Mammography uses radiation and compression; ultrasound depends on user expertise; MRI requires time and intravenous contrast. Development of novel technologies for breast imaging may be improved with patient surveys.

METHODS

Breast cancer patients scheduled for breast operations or undergoing neoadjuvant therapy were enrolled in studies to evaluate photoacoustic computed tomography (PACT) at a single institution. After each imaging session, the patients were surveyed. The survey included Likert scale, multiple choice, and open-ended questions.

RESULTS

Of 49 patients, 86 % completed at least one survey with 42 % completing three. Survey completion took <10 min. Features assessed specific to the imaging technology included water bath, duration, positioning, and environment. Patients overwhelmingly reported ease of PACT over mammography and MRI. Suggestions included better cushioning, improved head support, well-fitting laser safety glasses.

CONCLUSION

Photoacoustic breast imaging is feasible to breast cancer patients. User feedback informs on clinical technology improvement.
