[Diagnosis of breast diseases in a certified breast center].
Hödl P Abstract The beginning of the 21st century has seen immense improvements in the quality of diagnosis and treatment of breast cancer due to several, simultaneous developments. In particular, the introduction of a certification program from the German Cancer Society based on level III guidelines has enhanced the transparency and quality of treatment of breast diseases for all actors. As a result, patients have benefited from intensified cooperation especially between core disciplines in breast disease, gynecology, pathology, and radiology. The standardized and synoptic reading of multiple diagn...

[Pediatric bone marrow alterations].
Abstract The age-dependent development of the bone marrow follows a constant pattern and has an impact on the localization and morphology of various bone marrow processes. Physiological, reactive and benign bone marrow alterations must be differentiated from inflammatory or malignant infiltrations. In many cases, a specific age distribution pattern and typical morphological characteristics in magnetic resonance imaging (MRI) enable a diagnostic classification. The only adequate imaging modality that can provide information about the bone marrow composition is MRI. PMID: 33399889 [PubMed - as su...

[Chemical exchange saturation transfer (CEST) : Magnetic resonance imaging in diagnostic oncology].
CONCLUSION: CEST enables the detection of lowly concentrated metabolites, such as peptides and glucose, through selective saturation of metabolite-bound protons and subsequent magnetization transfer to free water. This technology yields additional information about metabolic activity and the tissue microenvironment without the need for conventional contrast agents or radioactive tracers. Various studies, mainly conducted in patients with neuro-oncolgic diseases, suggest that this technology may aid to assess tumor malignancy as well as therapeutic response prior to and in the first follow-up after intervention.

[Update: transitional fractures : Osseous injuries in growing up adolescents-correct nomenclature, radiological diagnostics and treatment].
Abstract Transitional fractures are special forms of epiphyseal injuries in adolescents in whom the growth plate is already partially closed. Due to the partial ossification specific stereotypical fracture patterns can develop, which can be differentiated into twoplane, triplane I and triplane II fractures, depending on the involvement of the metaphysis and the number of fragments. At the beginning of the diagnostics conventional projection radiography in two planes is used; however, due to the complex fracture patterns computed tomography (CT) is often indicated, also for preoperative planning. The treatment depe...

CONCLUSION: Overall, this hypothesis could not be confirmed. In several ways, the trial yields interesting information in the field of cardiac imaging. First, a positive stress test result was not associated with a prognostic benefit of revascularization. Second, even though the evaluation of coronary CTA was not part of the protocol, the good outcome achieved by using coronary CTA as a "gatekeeper" during randomization supports the potential of coronary CTA as a diagnostic tool-both first- and second-line-when CAD is suspected. However, the trial also raises new questions in the field of card...

Therefore, at the time of diagnosis the gastrointestinal tract may already be severely affected.

Abstract The term CUP syndrome (cancer of unknown primary) refers to a multifaceted clinical picture in which the affected patients have lymph node and/or distant metastases without the location of the primary tumor being known.
