[Therapeutic relevance of HRCT findings from a pneumological viewpoint.]
Abstract The high-resolution computed tomography (HRCT) technique is an essential component in diagnosing interstitial lung disease (ILD) as it provides important and specialized information and a much greater accuracy than chest X-rays. It contributes to a narrowing down of the differential diagnoses and is also important for planning further invasive investigations, e.g. bronchoscopy, bronchoalveolar lavage, transbronchial lung biopsy and surgical lung biopsy, if needed. An accurate diagnosis of ILD is based on a multidisciplinary discussion involving pulmonologists, radiologists and pathologists experienced in ...

[HRCT technique with low-dose protocols for interstitial lung diseases.]
Abstract CLINICAL/METHODICAL ISSUE: For optimal visualization of the lung parenchyma a dedicated computed tomography (CT) examination protocol has to be selected. STANDARD RADIOLOGICAL METHODS: High resolution CT (HRCT) is the best technique for non-invasive evaluation of the lung parenchyma. ACHIEVEMENTS: Given the possibility to examine the complete lungs within one breath hold, assessment of disease severity and distribution is easily possible. Various parameters have to be considered to generate optimal image quality and best possible clinical results. PRACTICAL RECOMMENDATIONS: This review arti...

[Oncological diseases and postoperative alterations of the bladder and urinary tract.]
r S Abstract In the challenging evaluation of upper urinary tract malignanciesmultidetector computed tomography (CT) has become the standard imaging method. Cross sectional imaging not only allows the detection and visualization of the tumor itself but also provides nodal and metastasis staging in one examination (one-stop-shop). The majority of urothelial carcinomas are located in the urinary bladder. In this case, CT and more recently magnetic resonance imaging (MRI) can also deliver decisive information regarding TNM classification. A combination of clinical, histological, morphological and functional parameter...

[Infectious diseases and injuries of bladder and urinary tract.]
r S Abstract Urinary tract infections are the most common infectious diseases in Germany. In most cases clarification does not rely on imaging techniques other than sonography and is made mostly based on clinical symptoms. Computed tomography (CT) and magnetic resonance imaging (MRI) can be used in selected cases to find the cause and detection or exclusion of complications, e.g. recurrent or atypical and complicated courses. The method of choice for clarification of urolithiasis is CT. Using low-dose techniques, detection or exclusion of urinary stones can be achieved with a high sensitivity and specificity as we...

[Endocrine tumors : Clinical overview.]
Abstract The term endocrine tumor incorporates all neoplasms which originate from the various endocrine organs. Endocrine tumors can be characterized by different criteria: localization, endocrine function, dignity (i.e. tumorigenesis, sporadic or hereditary). These characteristics also determine the clinical outcome. The clinical history, symptoms and physical examination findings (e.g. amenorrhea, skin alterations, striae, virilization, increased blood pressure and flush) direct the diagnostic process of functioning endocrine tumors. Laboratory findings (endocrine parameters) are needed to establish a diagnosis ...

Abstract CLINICAL/METHODICAL ISSUE: Adrenal masses are very common and are usually detected incidentally. Less frequently, imaging is performed for the localization of the underlying lesion in the case of endocrine disease. The differentiation between adenomas and non-adenomas is fundamental. METHODICAL INNOVATIONS: Adenomas show a low density on unenhanced computed tomography (CT) and a rapid washout of contrast agents. In magnetic resonance imaging (MRI) adenomas are characterized by a low signal in opposed phase imaging as compared to in phase imaging. PERFORMANCE: According to the literature a densit...

Abstract The (supra) sellar and pineal regions are relatively common sites for pediatric brain tumors; however, the distinct spectrum of space-occupying lesions is in marked contrast to that of the adult population. Craniopharyngeoma represents the most common intrasellar and/or suprasellar lesion in children, whereas the pituitary adenoma typical for adults- is generally rare. The pineal region is a predilection site for germ cell tumors in pediatric patients, while in adults this cancer category is largely confined to the gonads. The role of imaging is in the early detection of lesions, adequate demonstration of...

Structured reporting does not increase the quality of a radiological report but has many advantages in research, teaching and quality management. Using standard RadLex terms facilitates translation and ontological assignment of a report. The Reporting Initiative of ...

Abstract Solitary plasmacytoma and multiple myeloma require a differentiated radiotherapy. The irradiation for plasmacytoma with an adequate total dose (medullary 40-50 Gy or extramedullary 50-60 Gy) leads to a high degree of local control with a low rate of side effects. In cases of multiple myeloma radiotherapy will achieve effective palliation, both in terms of recalcification as well as reduction of neurological symptoms and analgesia. In terms of analgesia the rule is the higher the single dose fraction the faster the reduction of pain. As part of a conditioning treatment prior to stem cell transpla...

CONCLUSION: The MRI technique has a sensitivity of approximately 80 % for detection of malignant pulmonary nodules compared to the reference standard low-dose computed tomography (CT) and is thus somewhat inferior to CT. Advantages of MRI on the other hand are a higher specificity in differentiating malignant and benign pulmonary nodules and the absence of ionizing radiation exposure. A systematic use of MRI as a primary tool for detection and characterization of pulmonary nodules is currently not recommended due to insufficient data.
