[Pulmonary carcinoid tumors].
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...

Abstract CLINICAL/METHODICAL ISSUE: Magnetic resonance spectroscopy (MRS) is an important non-invasive method that can reveal the concentration and spatial distribution of particular biochemically relevant tissue metabolites. STANDARD RADIOLOGICAL METHODS: Proton MRS is routinely applicable in the clinical setting providing good quality results even with a moderate magnetic field strength of 1.5 T. Relative values of metabolite concentrations are mostly used for the assessment of metabolic disorders. METHODICAL INNOVATIONS: Absolute quantification of metabolites can be achieved by means of interna...

[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...

Even though chest x‑ray imaging is frequently performed in asymptomatic patients for preoperative assessment, clinically relevant incidental findings are relatively scarce. 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...

[Clinical magnetic resonance imaging : Frequent incidental cerebral findings].
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. Radiological imaging in combination with the medical history ...

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...
