“…Manufacturers, such as Hologic and GE Healthcare, offer upgrade paths for standard mammography systems to become breast tomosynthesis capable. Other than DBT, DT is also advantageous in a variety of clinical contexts, including chest, head and neck, orthopedic, and emergency imaging (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). The aims of this article are (a) to provide radiologists and radiologic technologists with knowledge about the basic facts and acquisition technique of DT, (b) to illustrate whole-body applications of DT by presenting a broad variety of clinical images, and (c) to demonstrate the clinical utilities and limitations of DT for these applications.…”

With flat-panel detector mammography, radiography, and fluoroscopy systems, digital tomosynthesis (DT) has been recently introduced as an advanced clinical application that removes overlying structures, enhances local tissue separation, and provides depth information about structures of interest by providing high-quality tomographic images. DT images are generated from projection image data, typically using filtered back-projection or iterative reconstruction. These low-dose x-ray projection images are easily and swiftly acquired over a range of angles during a single linear or arc sweep of the x-ray tube assembly. DT is advantageous in a variety of clinical contexts, including breast, chest, head and neck, orthopedic, emergency, and abdominal imaging. Specifically, compared with conventional mammography, radiography, and fluoroscopy, as a result of reduced tissue overlap DT can improve detection of breast cancer, pulmonary nodules, sinonasal mucosal thickening, and bone fractures and delineation of complex anatomic structures such as the ostiomeatal unit, atlantoaxial joint, carpal and tarsal bones, and pancreatobiliary and gastrointestinal tracts. Compared with computed tomography, DT offers reduced radiation exposure, better in-plane resolution to improve assessment of fine bony changes, and less metallic artifact, improving postoperative evaluation of patients with metallic prostheses and osteosynthesis materials. With more flexible patient positioning, DT is also useful for functional, weight-bearing, and stress tests. To optimize patient management, a comprehensive understanding of the clinical applications and limitations of whole-body DT applications is important for improvement of diagnostic quality, workflow, and cost-effectiveness.

“…In another study on 100 patients with wrist trauma [14], sensitivity of radiography for any fracture was 61-80 %, sensitivity of tomosynthesis 77-87 %, and of CT 86-95 %. It has also been used for evaluation of fracture healing [15], with similar results. In peripheral arthritis imaging, it has been shown to be better than radiography but not as good as CT [16] but almost as good as MRI in detecting erosions [17].…”

“…Dies ist ein neuartiges Verfahren bei der die Röhren-Detektor-Einheit halbkreisförmig um das Handgelenk des Patienten rotiert und aus unterschiedlichen Projektionen eine Serie von digitalen Projektionsradiogrammen erstellt [11]. In der Literatur wird die Detektionsrate von Kahnbeinfrakturen besser als die der Projektionsradiographie, jedoch schlechter als die der CT beurteilt [25,26]. Die Strahlenbelastung liegt in einer ähnlichen Größenordnung wie bei einer konventionellen Röntgendiagnostik.…”

ZusammenfassungKlinische und radiologische Diagnostik sind die Grundlage jeder differenzierten Therapieplanung karpaler Pathologien. Gerade bei der Kahnbeindiagnostik sind nicht nur die Auswahl und korrekte Durchführung der bildgebenden Verfahren entscheidend, sondern es müssen auch deren methodische Limitationen berücksichtig werden. Kaum eine andere Fraktur wird so häufig nicht erkannt, da nicht abgeklärt oder übersehen. Gleichzeitig führen die Folgen einer verspätet und/oder nicht behandelten Kahnbeinfraktur zu aufwändigen, nicht immer erfolgreichen Folgetherapien und langfristig zu funktionellen Einschränkungen. Diese Arbeit gibt einen Überblick über die klinische und bildgebende Diagnostik bei Kahnbeinfrakturen und -pseudarthrosen.

Digital Tomosynthesis to Evaluate Fracture Healing: Prospective Comparison With Radiography and CT

Abstract: Tomosynthesis provides diagnostic information superior to that of ra diography in postoperative evaluation of wrist fractures with lower cost and radiation than CT and should be considered in fracture follow-up imaging of other bones.
