Due to small cells, some rows have been suppressed by aggregating across other rows. 1Women may receive more than one type of imaging but are categorized only once in the table by the highest intensity of imaging. The hierarchy is PET/PET-CT > CT > MRI > mammogram with or without ultrasound (as the base category). 2MRI: magnetic resonance imaging. 3CT: computed tomography. 4PET/PET-CT: positron emission tomography. 5Patients may be included in more than one health insurance category if dual-enrolled. This categorization allows nonqualifying enrollment in the period ±60 days of diagnosis. 6The possibility of being insufficient claims or Medicaid with limited enrollment prior to diagnosis.
