Nevertheless, sports also can cause injury and overuse leading to sport-specific problems, which are often a challenge in diagnosing and treatment. The history of the sport-related injury is crucial for further differential diagnosis. Careful inspection, palpation and functional testing can reveal the possible pathology and lead to an effective strategy in the diagnostic assessment using radiographic tools such as sonography, X-ray and MR imaging (MRI). In muscle and tendon injuries sonography can provide ready to use information concerning muscle tears and tendon ruptures or degenerative lesions. Plain X-rays give a good overview on joint conditions regarding the bone...

Number, size, localization, and morphology (shape, density, margins) contribute to evaluating the most probable differential diagnosis. "Classical" high resolution CT or high resolution image reconstructions from multiple row detector CT helical acquisitions achieve a detail resolution that makes it possible to distinguish findings by their typical predominance in certain anatomical compartments of the lung. The position of bronchial, vascular and lymphatic structures can be determined down to the secondary pulmonary lobule, the smallest subunit of the lung to be separated by septa of connective tissue.

Over the last two decades the increase in soccer players has mainly been due to increased interest by females. In general, soccer is a relatively safe sport activity, especially if minor injuries resulting in short periods of absence from playing or training are neglected. However, due to the high number of soccer players severe injuries are also frequent. These are a problem not only for the injured player and the team but may also become problematic for the socio-economic system. In up to 80-90% structures of the lower extremities are injured.

The medical history revealed recurrent abdominal pain. Duplex sonography showed large intrahepatic cystic structures, partially combined with a ribbon-shaped flow signal inside, as well as multiple cysts in the kidneys. The following MRI identified these findings as dilatated bile ducts surrounding the portal vein branches. This is known as the central dot sign. Overall, this special constellation is indicative of Caroli's disease, a rare congenital cystic dilatation of the intrahepatic bile ducts.

Therefore, unfractionated heparin is administered during the intervention by an intra-arterial or intravenous approach. To avoid late onset thrombosis, administration of platelet function inhibitors is recommended. However, valid data are only available for acetylsalicylic acid (ASA). Therefore, ASA is recommended for long term medication. In several cardiological studies on stent implantation in coronary vessels the combination of ASA and clopidogrel for dual platelet inhibition has been proven to be effective.

They arise in the muscular layer of the esophagus, stomach, small intestines and rectum. Characteristic and important for the assessment of the extent of tumors is the peripheral rim vascularization of primary tumors and metastases. Indications for resection are given for tumors larger than 2 cm in size. Locally advanced GISTs can be advantageously treated with imatinib/sunitinib as neoadjuvant and it is often possible to select a low level of resection for this size of tumor and when the rim area is not hypervascularized.

Apart from B-mode ultrasound, colour Doppler ultrasound, pulsed-wave Doppler are used as well as contrast-enhanced ultrasound, which is being used more and more as a routine technique. Ultrasound is important in nephrology for the detection of renal artery stenosis and the resistance indices from pulse-wave Doppler are also helpful in acute renal failure. Nevertheless resistance indices should be used carefully and always by being aware of the pitfalls of this parameter.Another field of application for ultrasound is imaging of renal blood vessel damage as a result of trauma or iatrogenic ...

In addition to the primary conventional examination using color-coded duplex ultrasound, contrast-enhanced ultrasound (CEUS) with low mechanical index (low MI) may contribute to achieving a precise diagnosis. CEUS is a new and promising method in the diagnosis and follow-up of aortic and visceral artery lesions. Color-coded duplex ultrasound and CEUS with SonoVue(R) allow a rapid and non-invasive diagnosis especially in critically ill patients as these methods can readily be applied at the bedside.

They can be clearly distinguished from other mesenchymal tumors by immunohistochemistry in the vast majority of cases. Of the tumors 85% carry somatic activating mutations in the receptor tyrosine kinases KIT or PDGFRA. The detection of these molecular events has changed the treatment of inoperable and metastatic GISTs dramatically as up to 80% of tumors respond well to tyrosine kinase inhibitors.

This detailed view is necessary to support complex interventional strategies, such as transcutaneous valve replacement, interventional therapy of atrial fibrillation, implantation of biventricular pacemakers and assessment of myocardial perfusion. Currently, the major limitation of this technology is its insufficient temporal resolution which limits the visualization of fast moving parts of the heart.

MRI is of minor value in the estimation of the malignant potential of an osseous lesion. Although many bone tumors and tumor-like lesions present similar morphology at MRI, some entities can be diagnosed with good reliability. These include chondrogenic tumors, solitary and aneurysmal bone cysts, giant cell tumors, lesions containing fatty tissue and, to a certain extent, osteoid-osteomas and osteoblastomas.

The position of the patella itself is not influenced by arthroplasty, therefore any changes in the position of the tibiofemoral joint line are of special interest. The Figgie method to describe patella height delivers only absolute measurements, which makes it difficult to compare different radiographs. For this reason we developed a new JL/P quotient (JL: distance from the tibial plateau to the tibial tubercle, P: distance from the inferior pole of the patella to the tibial plateau) to enable better comparison.

When thickening of the interlobular septa or honeycombing are visible as predominant features, these patterns have a limited differential diagnosis. In this context, a detailed analysis of morphologic characteristics (e.g., smooth or nodular interlobular septal thickening) and of the pattern localisation (e.g., peripheral, basal and subpleural honeycombing) is required. Thickened intralobular septa, parenchymal bands, subpleural lines and the "interface sign" are all rather non-specific findings. However, if interpreted in the context of other CT findings, a differential diagnosis may also frequently be reported. PMID: 19430756 [P...

Perineural tumor spread is a potentially devastating complication and has a high impact on the therapeutic management and overall prognosis. In a large proportion of patients the disease remains asymptomatic and imaging (especially MRI) plays a crucial role in the detection of lesions. Familiarity with the pertinent anatomy, knowledge of the common spread pathways and an appropriate imaging strategy allow detection of the perineural spread of the disease in the majority of the cases.

For CT, a thin-slice venous phase with good bowel contrast is used. For MRI, an anti-peristaltic agent is necessary. Thin-slice T2- weighted TSE images with a high in-plane spatial resolution are particularly suitable for imaging the uterine wall; a parenteral contrast medium is absolutely necessary to demonstrate endometrial and ovarian carcinoma. In the guidelines, MRI is recommended only for cervical cancer FIGO 1b and higher stages; nevertheless, CT and MRI play an important role in preoperative diagnosis of these tumors. Lymph node staging is performed during surgery where possible. In patients with endometrial carcinoma, preoperative staging focuses on the infil...

Primarily, the growth rate is analyzed according to the Lodwick classification to differentiate a benign from a malignant lesion. With that, the lesser experienced clinician has solved the most important task in the diagnostic process. Further steps include analysis of the tumor matrix and the location within the tumor-bearing bone to make a specific diagnosis. Finally, the patient's age is included as a further parameter. With an optimized combination of the different parameters, the expert achieves a correct specific diagnosis in about 80% of cases.

Size and growth of liver metastases is of prognostic value. Due to arterial vascularization of metastases, transarterial embolization (TAE) is a suitable procedure, which can also be combined with chemotherapeutic agents. Indications for embolization or chemoembolization (TACE) are growth of liver metastases or inadequate symptom control. The majority of patients show clinical improvement and partial remission can be achieved in 50% of cases with 5-year survival rates of 50-60%. Response rates, survival or complications are not dependent on the embolization technique (TAE or TACE). Embolization is usually performed ...
