We should be cautious when using GSI-MARs because the image quality was affected by the prosthesis composition, energy (in keV) and DFOV. The metallic composition and size should be considered in metallic imaging with GSI-MARs reconstruction. Key Points   • Metal-related artefacts can be troublesome on musculoskeletal computed tomography (CT). • Gemstone spectral imaging (GSI) with dual-energy CT (DECT) offers a novel solution • GSI and metallic artefact reduction software (GSI-MAR) can markedly reduce these artefacts. • However image quality is influenced by the prosthesis...

Dynamic contrast enhanced ultrasound (DCE ultrasound) is a quantitative method with the advantage of being non-invasive, widely available, portable, cost effective, highly sensitive and reproducible using agents that are truly intravascular. Under the auspices of the initiative of the Experimental Cancer Medicine Centre Imaging Network, bringing together experts from the UK, Europe and North America for a 2-day workshop in May 2010, this consensus paper aims to provide guidance on the use of DCE ultrasound in the measurement of tumour vascular support in clinical trials. Key Points • DCE ultrasound can q...

Combining i.v. GLU with i.m. HBB provides an early onset of effect, sustained spasmolysis and the highest degree of motility impairment. Key Points   • Anti-persitaltic agents are widely used before various diagnostic procedures of the abdomen. • The combination of iv-glucagon with im-hyoscine provides reliable spasmolysis with early onset. • Intravenous spasmolysis is more reliable compared to intramuscular administration. • Intravenous glucagon has a prolonged spasmolytic effect compared to intravenous hyoscine.

The second dedicated reading detected significantly more ECF compared with the first clinical reading emphasising the importance of active search for extracardiac abnormalities when evaluating CMR studies. Key Points  • Many patients undergoing cardiac MR have significant extracardiac findings (ECF) • These impact on management and require additional work-up. • Wide review of scout and cine sequences will detect most ECFs. • Education of radiologists is important to identify ECFs on CMR studies.

SWE interpretation is at least as consistent as that of BI-RADS ultrasound B-mode features. Key Points  • Shear wave ultrasound elastography can measure the stiffness of breast tissue • It provides a qualitatively and quantitatively interpretable colour-coded map of tissue stiffness • Intraobserver reproducibility of SWE is almost perfect while intraobserver reproducibility of SWE proved to be moderate to substantial • The most reproducible SWE features between observers were SWE image homogeneity and maximum elasticity Content Type Journal ArticleCategory BreastPages 1-10DOI 10.1007/s00330-01...

Age and the AAo diameter were the parameters correlating best with presence and amount of vortices. Findings underline the importance of age- and geometry-matched control groups for haemodynamic studies. Key Points  • Secondary blood flow patterns (helices, vortices) are commonly observed in the aorta • Secondary flow patterns predominantly depend on patient age and aortic diameter • Geometric factors show a lesser impact on blood flow patterns than age and diameter • Future analyses of flow patterns should incorporate age- and diameter dependencies Content Type Journal ArticleCategory Magnetic ResonancePages ...

Early discharge with a negative 64-slice CCT is associated with very low risk of cardiac events at 6 months. Key Points  • 64-slice coronary computed tomography (CCT) offers a critical role in acute chest pain. • 64-slice CCT allows differentiation between significant and non-significant coronary artery stenosis. • Normal 64-slice CCT allows rapid discharge of patients with ACP. • 64-slice CCT helps make appropriate therapeutic decision in patients with ACP.

This study shows how these parameters can be identified in the MD and FA values, and thus suggests the implementation of MRI routine protocols for diagnosing MS with the DTI analysis, since it can provide valuable information otherwise unobtainable. Key Points   •  Magnetic resonance imaging is widely performed in multiple sclerosis (MS) patients •  Diffusion tensor imaging (DTI) can be implemented using a 3T magnet •  DTI provides quantitative parameters as mean diffusivity (MD) and fractional anisotropy (FA) •  MD and, especially, FA can help evaluate...

Further benefits are a lower irradiation dose and higher isovolumetric resolution compared with standard CT. Key Points    • Flat panel computed tomography (fpCT) helps otosurgeons design precise stapes protheses • fpCT allows a prediction of the postoperative hearing outcome in patients • fpCT is an adequate imaging technique for immediate postoperative quality control.

Low sensitivity, however, precludes effective population screening at this threshold. Key Points  • Unenhanced CT liver attenuation is highly specific for diagnosing moderate/severe hepatic steatosis. • Unenhanced CT can identify large cohorts for epidemiological studies of incidental steatosis. • Unenhanced CT is not, however, effective for population screening for hepatic steatosis.

A suggested format would be: HUkeV. Key Points  • Spectral computed tomography uses K-edge and slope effects to identify element signatures. • New visualisation tools will be required to efficiently display spectral CT information. • This paper demonstrates HU variation with keV using the Medipix3 chip. • HU keV is a suggested format when stating spectral HU measurements.

Our experience suggests that Doppler ultrasound may not be clinically reliable and more studies are needed to clarify its role, if any. Key Points • Chronic cerebrospinal venous insufficiency is a controversial topic in multiple sclerosis. • Ultrasound assessment of extracranial veins has yielded different results in the literature. • These differences may be due to dependence on Doppler and selection bias. • We found variations in vertebral vein flow in patients with multiple sclerosis.

Pathological diagnosis by fine needle aspiration cytology (FNAC) or core biopsy is often required before proceeding to definitive treatment. It is not uncommon for the cytology result to come back as inadequate for various reasons. The unique design of the end-cutting biopsy needle in our experience makes it a good choice for use in obtaining both transcutaneous and intraoral biopsy under ultrasound guidance of neck lesions and serves as a useful alternative or adjunct to FNAC. Although there is, as yet, only a limited evidence base about end-cutting in comparison to side-cutting needles, they carry several potential advantages. Key Points • End-cutting needles are safe ...

Thus, while contrast enhancement is justified to achieve maximum sensitivity, unenhanced images may be sufficient for routine PET/CT in NET patients. Key Points  • Contrast media moderately improve the sensitivity of (68)Ga-DOTATOC PET/CT for neuroendocrine tumours. • Contrast media hardly affect the specificity of (68)Ga-DOTATOC PET/CT for neuroendocrine tumours. • Unenhanced PET/CT is sufficient for routine imaging of patients with neuroendocrine tumours.

As long as randomised studies are pending, we recommend entering an individual decision-making process with every patient. Key Points   • Large colorectal liver metastases can be effectively treated by stereotactic radiofrequency ablation (SRFA). • Using SRFA the overall survival is not affected by tumour size. • SRFA achieves similar overall and disease-free survival rates as surgical resection. • SRFA challenges surgical resection as the first-line treatment for colorectal liver metastases.

The levels of Cho and Lact measured in the grey matter are the most indicative of survival. It is therefore advised to include grey matter brain tissue in the region of interest examined by multivoxel MR spectroscopy. Key Points    • Magnetic resonance spectroscopy can identify brain metabolic changes in perinatal asphyxia. • Choline and lactate levels in grey matter seem the best indicators of survival. • Both grey and white matter should be examined during spectroscopy for perinatal asphyxia.

This is relevant in clinical practice allowing expectant management in RTE selected cases. The role of RTE seems less relevant for larger lesions because most of them are malignant at clinical and ultrasound assessment, limiting RTE to simply confirmation role. Key Points   • An emerging role for Elastography in allowing surveillance for small testicular lesions • Elastography can better differentiate benign from malignant testicular lesions • Follow up can be reduced for elastic testicular lesions at Elastography.

Differences between LDX 2D and 3D measurements were noted in the femoral mechanical angle, femoral neck-shaft angle and tibial length. Moderate to good interobserver agreement for the 3D LDX measurements were found. Key Points   • Low radiation dose is essential when assessing potential lower extremity discrepancies • A new biplanar low-dose X-ray device can assess such discrepancies in children/adolescents • This LDX device provides equally reliable 3D measurements as prevalent practice LDX measurements carry good overall interobserver agreement.

Customised devices and modified use of conventional EVAR devices now overcome challenging landing zones. Fenestrated and branch devices, together with chimney and periscope techniques can be used to overcome proximal landing zone challenges, while iliac branch grafts and sandwich techniques have been used to address challenging distal iliac landing issues. Due to the novelty of these techniques, life-long surveillance is crucial, with CT Aortography (CTA) being the key investigation. Currently, the body of literature surrounding the imaging aspects of these techniques is scarce. The...

It was more sensitive than PET/CT and more specific than MRI. Fused PET-MRI therefore seems well suited for surgical and interventional treatment planning of NET liver metastases. Key Points  • Ga-68-DOTATOC PET–Gd-EOB-DTPA MRI fusion can improve imaging of liver metastases of neuroendocrine tumours. • This technique appears more sensitive than PET/CT for staging NET hepatic metastases. • Ga-68-DOTATOC PET–Gd-EOB-DTPA MRI fusion is more specific than MRI alone.
