Stereotactic body radiation therapy (SBRT) for hepatocellular carcinoma: imaging evaluation post treatment.
Abstract Surgical resection, when feasible, is the standard of care for hepatocellular carcinoma (HCC). However, many tumors are not resectable at the time of diagnosis. Recently, stereotactic body radiation therapy (SBRT) has emerged as a non-invasive local therapy for both non-resectable primary hepatic malignancies as well as hepatic metastases. Knowledge of the expected hepatic parenchymal appearance post treatment, as well as potential pitfalls and complications, is essential for accurate evaluation of treatment response. This pictorial review provides a fundamental description of the SBRT technique, outlines...

WB MRI and oncology: recent major advances.
Abstract Magnetic Resonance Imaging (MRI) is a very attractive approach for tumor detection and oncological staging with its absence of ionizing radiation, high soft tissue contrast and spatial resolution. Less than ten years ago the use of Whole Body MRI (WB-MRI) protocols was uncommon due to many limitations, such as the long acquisition times and limited availability. This decade has marked substantial progress in WB-MRI protocols. This very promising technique is rapidly arising from the research world and is becoming a commonly used exam for tumor detection, due to recent technological developments and valida...

Safety of working patterns among UK neuroradiologists: what can we learn from the aviation industry and cognitive science?
Abstract As the volume and complexity of imaging in the UK continues to rise, there is pressure on radiologists to spend increasing lengths of time reporting to cope with the growing workload. However, there is limited guidance for radiologists about structuring the working day to achieve the necessary balance between satisfactory reporting volume and maintaining quality and safety. We surveyed 86 Neuroradiologists (receiving 59 responses), regarding time spent reporting, frequency and duration of work breaks, and break activities. Our results demonstrate that some neuroradiologists report for up to 12 hours a day...

The different faces of renal angiomyolipomas on radiologic imaging: a pictorial review.
Abstract Renal angiomyolipoma (AML) is an uncommon renal tumour, generally composed of mature adipose tissue, dysmorphic blood vessels, and smooth muscle. Identification of intratumoural fat on unenhanced CT images (UECT) is the most reliable finding for establishing the diagnosis of renal AML. However, AMLs sometimes exhibit atypical findings, including cystic as well as solid forms; some of these variants overlap with the appearance of other renal tumours. A rare type of AML, the epithelioid type, possesses malignant potential. The aim of this pictorial review is to gather the different imaging features of AMLs ...

L1 vertebral density on CT is too variable with different scanning protocols to be a useful screening tool for osteoporosis in everyday practice.
CONCLUSION: There is significant variability in the L1 vertebral body CT density due to differences in acquisition variables such as kVp and timing post iv contrast medium. Advances in knowledge: Previous studies suggested that L1 CT density could be used to screen for osteoporosis. The current study cautions that it is not possible to define a single L1 density threshold for screening, due to the number of variables within a wide range of scanning protocols for different imaging indications in everyday practice.

Nitroimidazoles as hypoxic cell radiosensitizers and hypoxia probes: misonidazole, myths, and mistakes.
Abstract Nitroimidazoles have been extensively explored as hypoxic cell radiosensitizers but have had limited clinical success, with efficacy restricted by toxicity. However, they have proven clinically useful as probes for tumour hypoxia. Both applications, and probably much of the dose-limiting toxicities, reflect the dominant chemical property of electron affinity or ease of reduction, associated with the nitro substituent in an aromatic structure. This single dominant property affords unusual, indeed extraordinary flexibility in drug or probe design, suggesting further development is possible in spite of earli...

The management of deep-seated low grade lipomatous lesions.
Abstract Deep-seated, low grade lipomatous lesions detected on imaging often cause uncertainty for diagnosis and treatment. Confidently distinguishing lipomas from well-differentiated liposarcomas (WDL) is often not possible on imaging. The approach to management of such lesions varies widely between institutions. Applying an evidenced-based approach set around published literature that clearly highlights how criteria such as lesion size, location, age and imaging features can be used to predict the risk of WDL and subsequent de-differentiation would seem sensible. Our aim is to review the literature and produce a...

Hyperpolarized carbon-13 magnetic resonance spectroscopic imaging: a clinical tool for studying tumour metabolism.
Abstract Glucose metabolism in tumours is reprogrammed away from oxidative metabolism, even in the presence of oxygen. Non-invasive imaging techniques can probe these alterations in cancer metabolism providing tools to detect tumours and their response to therapy. Although Positron Emission Tomography with [18F]2-fluoro-2-deoxy-D-glucose (18F-FDG PET) is an established clinical tool to probe cancer metabolism, it has poor spatial resolution and soft tissue contrast, utilises ionizing radiation and only probes glucose uptake and phosphorylation and not further downstream metabolism.

Analysis of intra and extra-myocellular lipids in the multifidus muscle in patients with chronic low back pain using MR spectroscopy.
Abstract OBJECTIVE: To analyze the intra (IMCL) and extra-myocellular lipids (EMCL) concentration in the multifidus muscle (Mm) using MR spectroscopy (MRS) in patients with low back pain (LBP), and to evaluate the correlation between those lipid concentrations and age, obesity, atrophy of the Mm and LBP intensity. METHODS: Sixty LBP patients underwent routine diagnostic MRI of the lumbar spine before undergoing imaging for the study. Body mass index (BMI), as an indicator of obesity and visual analogue score (VAS), as an indicator of LBP were also measured. Proton MRS was acquired with a single-voxel point-re...

Image quality assessment of silent T2 PROPELLER sequence for brain imaging in infants.
CONCLUSION: The silent T2 PROPELLER sequence reduces acoustic noise and generated comparable image quality to that of the conventional sequence. Advances in knowledge: This is the first report to compare silent T2 PROPELLER images with that of conventional T2 PROPELLER images in children.

The utility of contrast-enhanced hypodense sign for the diagnosis of pulmonary invasive mold disease in patients with haematological malignancies.
CONCLUSION: The high specificity of the HyS strongly supports the diagnosis of pulmonary IMD in neutropenic patients, and is highly suggestive breakthrough fungal disease in patients on mould-active antifungal prophylaxis. Advances in knowledge: This is the first systematic analysis of the hypodense sign on contrastenhanced CT; the sign can support the diagnosis of invasive mould disease when other CT signs are uncertain.

Does the total dysphagia risk score correlate with swallowing function examined by video fluoroscopy?
CONCLUSION: Patients with high risk TDRS scores have higher SPS scores when compared to the intermediate group and the intermediate and low risk group together. However, low risk patients in our patient cohort could not be distinguished from high or intermediate risk patients. Advances in knowledge: TDRS was never correlated with video fluoroscopies in past studies. The hypothesis of this paper was to see if the TDRS could guide us to see which patients are at risk for high scores on SPS and PAS and might need a videofluoroscopic examination in the follow up. Given the poor correlations in our study however, we cannot reco...

Classification of breast cancer from ultrasound imaging using a generic deep learning analysis software: a pilot study.
CONCLUSION: DLS may aid diagnosing cancer on breast ultrasound images with an accuracy comparable to radiologists, and learns better and faster than a human reader with no prior experience. Further clinical trials with dedicated algorithms are warranted. PMID: 29215311 [PubMed - as supplied by publisher] (Source: The British Journal of Radiology)

The clinical value of secretin-enhanced MRCP in the functional and morphological assessment of pancreatic diseases.
Abstract Secretin-enhanced MRCP (S-MRCP) provides a non-invasive way with which to evaluate pancreatic duct (PD) anatomy and exocrine pancreatic function. S-MRCP can be added to the routine pancreas MR exam in equivocal cases. Moreover, it can detect subtle PD involvement, allowing diagnosis of early, rather than end-stage, pancreatic diseases. Although S-MRCP is a valuable non-invasive diagnostic method, it is only performed in a few centers due to high cost. Furthermore, less familiarity with its indications, the exam technique, and image interpretation also contribute to its limited use. Thus, the purpose of th...
