TL;DR: A dual source CT (DSCT) scanner provides temporal resolution equivalent to a quarter of the gantry rotation time, independent of the patient's heart rate, and allows to go beyond conventional CT imaging by obtaining dual energy information if the two tubes are operated at different voltages.

TL;DR: The role of imaging in assessment of salivary gland tumour is to define intra- glandular vs. extra-glandular location, detect malignant features, assess local extension and invasion, detect nodal metastases and systemic involvement, and determine tumour extent.

TL;DR: The purpose of this report is to summarize the medical literature reporting of biopsy-proven NSF cases in which the authors specifically investigated patient exposure to gadolinium-based contrast agents (Gd-CA).

TL;DR: Dual energy CT perfusion imaging is able to display pulmonary perfusion defects with good agreement to scintigraphic findings and DECT can provide a pulmonary CT angiogram, high-resolution morphology of the lung parenchyma and perfusion information in one single exam.

TL;DR: The purpose of this review article is to present the most relevant artifacts that arise in 3-T MRI, to provide some physical background on the formation of artifacts, and to suggest strategies to reduce or avoid these artifacts.

TL;DR: This review describes the current status of gadolinium-CA, their mechanism of action, chemical structure, pharmacokinetics, dosage, elimination, nephrotoxicity and adverse events.

TL;DR: The commonest conditions encountered in clinical radiological practice are reviewed, including maxillofacial deformities, complicated dental impactions, maxill ofacial trauma, jaw lesions (cysts, neoplasms, fibro-osseous lesions (FOLs) and infections), and temporomandibular joint pathology.

TL;DR: It is shown that the RS-EPI scheme may be an important alternative sampling strategy to EPI to achieve high resolution T2- Weighted and diffusion-weighted images.

TL;DR: The present article reviews less common tumors of this region, such as chondrosarcoma, lymphoma, minor salivary gland tumors and lipoma, and discusses the clinical role of Computed Tomography, Magnetic Resonance Imaging and PET CT in the pretherapeutic workup and postTherapeutic follow-up of patients with squamous cell carcinoma of this area.

TL;DR: Advances in CT technology have resulted in increases in diagnostic accuracy and proportion of assessable coronary segments, but per patient, accuracy may be lower and CT may have more limited clinical utility in populations at high risk for CAD.

TL;DR: The results showed that 64-slice CT angiography has a high-diagnostic value in the detection of CAD, and severe coronary artery calcification seems to be the major factor affecting the visualisation and assessment.

TL;DR: Because inter- and intra-observer agreement with the BI-RADS lexicon for US is good, the use of BI-CAD lexicon can provide accurate and consistent description and assessment for breast US.

TL;DR: The stability of Gd-CA seems to be an important factor in the pathogenesis of the serious complication of nephrogenic systemic fibrosis as the binding between Gd(3+) with the negatively charged carboxyl groups is stronger in comparison to that with amides or alcohol in the non-ionic preparations.

TL;DR: MRI has advantages in demonstrating pathology of the brain, lungs, complex syndromes, and conditions associated with reduction of amniotic fluid, as well as in evaluating fetal and extra-fetal structures for a variety of clinical indications.

TL;DR: Whole-body MRI (WBMRI) is a novel technique that makes imaging of the whole patient in a manner similar to scintigraphy or positron emission tomography (PET) possible, it is without exposure to radiation and thus gaining increasing importance and application in pediatrics.

TL;DR: WB-MRI and PET-CT are useful for the detection of tumor recurrence in the follow-up of breast cancer, and WB-MRI is highly sensitive to distant metastatic disease.

TL;DR: As planned prospective studies get underway, it is of paramount importance that researchers and clinicians realize that NSF remains a very challenging diagnosis, and that both clinical and histopathological criteria must be employed to reach the most accurate diagnosis possible.

TL;DR: A meta-analysis of the relevant literature and discussed the role of MR imaging of the shoulder and elbow compared with other diagnostic imaging modalities, finding that plain MRI or MRA have the advantage towards CTA to detect occult bone injuries.

TL;DR: Tailoring of the CTCA protocol to the HR and BMI of the individual patient results in dose reductions of up to 86%, while maintaining a diagnostic image quality of the examination.

TL;DR: Non-linear blending of dual energy data can provide an improvement in CNR over linear blending and is accompanied by a visual preference for non-linear blended images.

TL;DR: This long-term follow-up study on a large group of HCC patients confirmed that RFA could not only achieve favorable outcome on stage I HCC, but also be an effective therapy for stage II-IV or recurrent HCC.

TL;DR: Non-conventional magnetic resonance-derived metrics that can selectively measure the more destructive aspects of multiple sclerosis pathology and monitor the reparative mechanisms provide a better approximation of the pathological substrate of the multiple sclerosis plaques, have increased the understanding of the pathogenesis of the disease.

TL;DR: Sonoelastography seems to offer a new approach for differentiation of tissue stiffness of the prostate and may therefore improve prostate cancer detection.

TL;DR: Applications in skeletal muscle for determination of intramyocellular lipids (IMCL), which are involved in the pathogenesis of insulin resistance, and studies for short-term regulation of IMCL, as dietary intervention, exercise and fasting are presented.

TL;DR: Ischemia, especially the Lac/NAA in comparison with perfusion and diffusion weighted imaging seems to be a new measure for areas of metabolic need, and may help to better characterise the penumbra of the stroke and the final infarct size.

TL;DR: In experienced hands ultrasonography should be considered as an accurate modality for the initial investigation of rotator cuff, especially supraspinatus, tears.

TL;DR: While heart rate, heart rate variability and calcification all show an inverse correlation to IQ, severe calcium burden remains the single factor with translation of such effect into decrease of diagnostic accuracy.

TL;DR: A systematic review of the current biomedical literature surrounding the aetiopathogenesis and histopathological features of bone marrow oedema, reactive bone change and haemorrhage finds the use of the term bone marrow Oedema syndrome in a radiological context might be considered questionable.

TL;DR: The benefits and the current knowledge of 3.0 T whole-body MRI from an evidence-based perspective are reviewed and its clinical applications are summarized.

TL;DR: The addition of DW imaging to conventional T(2)W imaging provides better detection of rectal cancer.
