[The new law on radiation protection as a consequence of the EU safety standard of 2013].
Abstract The transformation of a European guideline (2013/59/Euratom) from 2013 into national law requires adaptation of the national statutory regulations. This year, all areas of protection from ionizing radiation will be subject to the new radiation protection law (StrlSchG). Through this, the German X‑ray and Radiation Protection Acts will be combined to form a higher level of authority. The main parts of the StrlSchG will receive a new classification and will be organized according to the exposure scenario: radiation protection in planned exposure scenarios, radiation protection in emergency exposure scenar...

[MR spectroscopy in metabolic disorders of the brain].
Abstract CLINICAL ISSUE: Metabolic disorders of the brain often present a particular challenge for the neuroradiologist, since the disorders are rare, changes on conventional MR are often non-specific and there are numerous differential diagnoses for the white substance lesions. STANDARD RADIOLOGICAL METHODS: As a complementary method to conventional brain MRI, MR spectroscopy may help to reduce the scope of the differential diagnosis. Entities with specific MR spectroscopy patterns are Canavan disease, maple syrup urine disease, nonketotic hyperglycinemia and creatine deficiency. PMID: 2850809...

[Certification guidelines and qualification courses].
Abstract German regulations require a license for using ionizing radiation in medicine. This license-called "Fachkunde"-varies for different medical procedures such as CT, fluoroscopy, radiography, or mammography. The required frequencies and training times also vary for different medical disciplines such as radiology, cardiology, vascular surgery, traumatology, nuclear medicine, and radiotherapy, among others. The quality criteria for a specific license require a minimum training time under supervision and a minimum frequency of a wide range of procedures. Depending on the radia...

Abstract The Digital Imaging Adoption Model (DIAM) has been jointly developed by HIMSS Analytics and the European Society of Radiology (ESR). It helps evaluate the maturity of IT-supported processes in medical imaging, particularly in radiology. This eight-stage maturity model drives your organisational, strategic and tactical alignment towards imaging-IT planning. The key audience for the model comprises hospitals with imaging centers, as well as external imaging centers that collaborate with hospitals. The assessment focuses on different dimensions relevant to digital imaging, such as software infrastructure and...

[Imaging diagnostics of breast metastases from extramammary tumors].
Abstract Breast metastases of solid extramammary tumors are very rare in comparison to primary malignancies of the breast and account for only 0.33-6.3% of all malignant neoplasms of the breast. The most common primary tumors are malignant melanoma, distant sarcomas, lung cancer, ovarian cancer, renal cell cancer and thyroid cancer in decreasing order of frequency. This review article summarizes the clinical features and the different imaging findings of breast metastases from different extramammary solid tumors. Breast metastases are often incidental findings in computed tomography (CT) or positron emission tomog...

Abstract Pulmonary carcinoids are rare low-grade malignant tumors, which arise from the neuroendocrine system. Approximately 80% of all pulmonary carcinoid tumors are the relatively low-grade typical carcinoids and 20% are the more aggressive atypical carcinoids. Most carcinoids arise from the central airways and only a minority of carcinoids are found in the lung periphery. While most of the peripheral carcinoids are asymptomatic, central carcinoids are symptomatic and present with hemoptysis, wheezing or bronchial obstruction. On computed tomography (CT), carcinoids frequently present as hypervascular pulmo...

[Biological mechanisms of radiation effects].
CONCLUSION: The time course of the reaction of tissues to radiation exposure extends over wide ranges up to many decades. The effects of radiation on tissues are classified into early and late and their pathobiology is significantly different. Various factors (R) influencing the clinical manifestation of radiation effects have been identified related to the exposure pattern. The radiation tolerance of normal tissue structures regarding the induction of functional deficits shows great variation but always has a threshold value, which is usually not exceeded in diagnostic procedures. The risk of a radiation-induced fata...

Abstract Impingement syndrome of the ankle is a clinical diagnosis caused posttraumatically by overuse due to repetitive mechanical loading or the presence of predisposing anatomical variants. Ankle impingement syndrome is characterized by chronic pain and limited range of movement caused by mechanical compression of bony or soft tissues within the joint compartments. Ankle impingement syndrome is classified according to the various anatomical locations around the tibiotalar joint as anterior, anterolateral, anteromedial, posterior or posteromedial. Various imaging modalities are helpful in confirming the cli...

This is due to the relatively low sensitivity of chest x‑rays where few clinically relevant incidental findings are to be expected, as any detectable pathologies will as a rule already be c...

n E Abstract The increasing use of magnetic resonance imaging (MRI) in clinical diagnostics means that patients and physicians are confronted more often with incidental findings. In the literature there are fluctuating data on the incidence of such findings and guidelines concerning the further procedure exist in only very few cases, such as incidental aneurysms and pituitary adenomas. The diagnostic and therapeutic implications which can be derived from incidental findings depend on multiple factors, such as anatomical location, patient age, comorbidity and patient wishes. For this reason it often makes sense to ...

Abstract Incidental findings are part of the routine radiological reporting workflow and describe findings which are not primarily the focus of the clinical context or the request of the referring physician. The clinical implications of such incidental findings can be very different, for example simple renal cysts or space-occupying lesions suspected of being tumors. A categorization of clinical findings according to the clinical relevance is therefore recommended. Documentation and communication of clinically relevant incidental findings are a part of the radiological reporting process and essential for redu...

Abstract The term nonthrombotic pulmonary embolism (NTPE) is defined as embolization of pulmonary arteries caused by foreign bodies (e. g. detached catheter fragments), biological substances (e. g. septic thrombus) or exogenous substances (e. g. gas). The frequency of NTPE is underestimated. Symptoms can cover the spectrum from undetectable to sudden death. In addition to mechanical obstruction of the pulmonary arteries, some NTPEs trigger an inflammatory cascade that causes deterioration of vascular, pulmonary and cardiac function.

Abstract Degenerative and traumatic ligament lesions of the carpometacarpal joints frequently occur at the thumb ray, whereas the carpometacarpal amphiarthrosis of other finger rays are rarely affected. The metacarpophalangeal and interphalangeal joints of the thumb and fingers are stabilized by bilaterally running collateral ligaments and palmar plates. At the base of the metacarpophalangeal joints, several ligaments of the extensor hoods guide the extensor tendons and coordinate the fine motoric skills of phalangeal flexing and extending. Several annular and cruciform ligaments hold the flexor tendons close to t...
