Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT03220893). This is a study registration, not published results. Lead sponsor: Mayo Clinic. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 3023 participants (ACTUAL). Conditions: Breast Carcinoma. Interventions: PROCEDURE: Digital Breast Tomosynthesis (DBT); RADIATION: Scintimammography. Primary outcome measures: Rate of Detection of Invasive Cancers , At year 1 screening. Brief summary: This study compares molecular breast imaging (MBI) and digital breast tomosynthesis (DBT) in screening patients with dense breast tissue. Breast imaging may help doctors find breast cancer sooner, when it may be easier to treat. Molecular breast imaging (MBI) uses an injection of a small amount of radioactive material that is taken up in tissues of the body that are actively changing, such as breast cancer. A specialized camera, called a gamma camera, takes pictures of the gamma rays emitted by this material. MBI may detect cancers that are not visible on mammograms. This study may help researchers determine how MBI testing compares to DBT screening.
