About

The investigators propose tomosynthesis as a imaging method in between of x-ray and CT. The expected value of this project is the definition of proven indications for tomosynthesis, which allow replacing CT. Specific goals are the early detection of pulmonary consolidations / parenchymal changes as well as the monitoring of patients with ostesynthetic implants.

Full description

The investigators propose tomosynthesis as a imaging method in between of x-ray and CT. The expected value of this project is the definition of proven indications for tomosynthesis, which allow replacing CT. Specific goals are the early detection of pulmonary consolidations / parenchymal changes as well as the monitoring of patients with ostesynthetic implants.

This is a prospective, single-center, non-randomised, non-blinded trial with Tomosyntheis of Patients referred to the investigators institution to assess lung alterations and bone structure. All patients will undergo chest x-ray and tomosynthesis after informed consent. In addition they will undergo an ultralow-dose CT, wich is used as standart reference. The radiation dose of each method will be recorded. After completion of these three examinations, the participation in the study is completed.

Enrollment: 60 patients

Inclusion criteria
