Quality Diagnostic Imaging Care at St. Peter’s

  • Accreditation by the American College of Radiation: Our breast imaging services are accredited by the American College of Radiation (ACR), one of the premier accrediting organizations for imaging studies. In addition, we track patient safety measures according to quality standards for radiology recommended by the ACR.
  • Lowest dose radiation: Our modern equipment provides higher quality images quickly, using lower doses of radiation. In addition, our CT scanners are equipped with software that automatically calculates the lowest dose of radiation needed to produce an effective diagnostic test. We also offer a low dose CT lung scan for lung cancer screening.
  • Reduced wait times: Our goal is to schedule you for testing within days of you calling for an appointment. We monitor our schedule daily to assess our wait times. If our wait times for any specific type of imaging extends to more than two weeks, we open up additional appointment times to get you in more quickly.
  • Advanced multidetector CT scans: We offer multidetector CT, or CAT scans. Multidetector CT (also known as multislice CT) provides incredibly fast, detailed images. This means that you will be in the scanner for a much shorter period of time, while we receive the highest quality images.
  • 3D mammogram and stereotactic breast biopsy: 3D breast imaging technology offers more comprehensive views for diagnosing breast cancer. At St. Peter’s Health, we have 3D mammograms (also known as tomosynthesis) and 3D stereotactic breast biopsy. Stereotactic breast biopsy is performed after a mammogram in which we find calcifications or lumps in the breast that need further investigation.
