[Hybrid imaging in prostate cancer : Status quo and future applications].
CONCLUSION: The use of PSMA-ligand PET has revolutionized PC imaging. Thus, PSMA-ligand PET is expected to play an even greater role in PC diagnostics in the future, especially as 18F-labeled PSMA ligands are now increasingly used. However, simultaneous image analysis of PET and CT as well as a differentiated image evaluation (clinical context, knowledge of common pitfalls) is mandatory.

[Bone tumors and metastases: tips for initial diagnosis and follow-up : Update 2019].
Abstract Benign bone tumors are frequently discovered as incidental findings, whereas malignant tumors and metastases often become clinically noticeable due to pain or swelling. The initial radiological diagnostics by conventional X‑ray imaging, magnetic resonance imaging (MRI) and computed tomography (CT) play an important role in the assessment of dignity and further treatment planning. The aftercare of bone tumors is necessary for the recognition of recurrences and distant metastases as well as the detection of complications, e.g. after implantation of a prosthesis. Implanted metal and posttherapeutic alterat...

Abstract CLINICAL ISSUE: Both the progress of surgical techniques and the demographic development with increasing numbers of multimorbid patients demand and also encourage radiology in the setting of trauma and acute emergencies. In addition to a fast and precise diagnostics, this also includes image-guided, minimally invasive therapy to control and treat several acute pathologies. STANDARD RADIOLOGICAL PROCEDURES: Computed tomography (CT) is not only important for the diagnosis of abscesses, active bleeding or other acute pathologies, but also allows minimally invasive therapy.

[Nonspecific low back pain and chronification].
Abstract Low back pain is the leading cause of incapacitation and medical rehabilitation. The purpose of this German National Health Care Guideline "Nonspecific low back pain" is to optimize the care of patients with low back pain. This guideline was drawn up by 29 professional societies and organizations. In the case of nonspecific low back pain, a detailed medical history and physical examination should be carried out first, but no further diagnostics unless there are indications of the so-called "red flags". For symptomatic treatment, medicine should be given in low doses, and phys...

CONCLUSION: Anamnesis and clinical examination play an important role in identifying patients with a real underlying pathology for the symptomatology in order to provide them with direct imaging for further evaluation. Corresponding pathology in most cases of acute back pain is generally not found but here psychosocial factors ("yellow flags") are in the foreground. Attention should always be paid to the presence of "red flags" and the possibility of extraspinal causes. PMID: 31925466 [PubMed - as supplied by publisher] (Source: Der Radiologe)

Interventional therapy in malignant conditions of the prostate.
awa M Abstract Interventional therapies are emerging modalities for the treatment of localized prostate cancer. Their aim is to reduce the morbidity associated with radical therapies (rT) by minimizing damage to non-cancerous tissue, with priority given to sparing key structures such as the neurovascular bundles, external sphincter, bladder neck, and rectum, while maintaining local cancer control. Interventional ablative technologies deliver energy in different ways to destroy cancer cells. The most widely investigated techniques are brachytherapy, external beam radiotherapy, cryotherapy, and high-intensity focuse...

CONCLUSION: To date there is no algorithm that has beyond doubt been proven to outperform double reporting by two certified breast radiologists.

Furthermore, the establishment of radio-patho-genomic correlations and their translation into clinical practice is hardly conceivable without AI.

Abstract Glomus tumors (paragangliomas) are rare, usually benign, neuroendocrine tumors that arise from nonchromaffin cells and can be multifocal or familial.

Depending on the location, clinical symptoms include neck swelling, hearing loss with pulse-synchronous ear noise or cranial nerve failures (IX-XI). Diagnosis is often delayed because of nonspecific symptoms. Diagnostically, tumor expansion and perfusion can be well visualized by color Doppler sonography. In the...

Abstract CONTEXT: Although in recent times more research has been done on interactions of metallic dental objects in magnetic resonance imaging (MRI), radiologists are often uncertain whether the objects should be removed or can be retained prior to an impending examination. On the one hand, they want to avoid unnecessary material removal which is associated with costs and potential damage of the dental object. On the other hand, they fear material-induced susceptibility artefacts will impair the diagnostic workup so that examinations will have to be repeated.
