TL;DR: Current preclinical findings and advances in instrumentation suggest that these molecular imaging methods have numerous potential clinical applications and will be translated into clinical use in the near future.

TL;DR: Current concepts and future directions of molecular ultrasound imaging are reviewed, including different classes of molecular ultrasounds contrast agents, ongoing technical developments of pre-clinical and clinical ultrasound systems, the potential of Molecular ultrasound for imaging different diseases at the molecular level, and the translation of molecular Ultrasound into the clinic.

TL;DR: The combination of ultrasound and SPECT/CT has incremental value in accurately localizing solitary parathyroid adenomas over either technique alone, and allows selection of patients with primary hyperparathyroidism who would be suitable for minimally invasive surgery.

TL;DR: The imaging techniques in making a diagnosis of AML are reviewed, including features of both characteristic lesions as well as atypical lesions, and current guidelines for follow-up and prophylactic treatment of these lesions are discussed.

TL;DR: Preoperative staging CT accurately distinguishes between tumours confined to the bowel wall and those invading beyond the MP; however, it is significantly poorer at identifying nodal status than multidetector CT, which provides the best results.

TL;DR: This work reviews the different types of breast biopsy devices currently available together with various localization techniques used, focusing on their advantages, limitations and current controversial clinical management issues.

TL;DR: This is the largest study of aortic arch variant anatomy in a living patient population and recognition and appreciation of these entities is of importance to the interventional and diagnostic radiologist alike.

TL;DR: The usefulness of diffusion imaging in assessing the aggressiveness of breast tumours is confirmed and ADC appears to be a promising parameter in the evaluation of the degree of malignancy of breast cancer tissue.

TL;DR: Imaging is central to this investigation because it can non-destructively and longitudinally characterize spatial variations in the tumour phenotype and environment so that the system dynamics over time can be captured quantitatively.

TL;DR: The role of imaging in follow-up and prognostication of progressive multifocal leukoencephalopathy is outlined, and the manifestations of PML are reviewed.

TL;DR: This initial experience with ultrasound breast elastography showed that it was more specific and more accurate than conventional ultrasound and can potentially reduce unnecessary breast biopsies.

TL;DR: Cardiac computed tomographic angiography (CTA) initially was a very high dose application, however, both clinicians and CT system manufacturers have done a large amount of work to reduce dose and dramatic changes have been achieved.

TL;DR: The postmenopausal women with osteoporosis exhibited a corresponding increase in vertebral marrow fat content as the bone density decreased, and MRS and DWI were helpful in evaluating the bone marrow changes.

TL;DR: Although MRI is the imaging method of choice for vertebral osteomyelitis and discitis in the early stages, it may show subtle, non-specific endplate subchondral changes; a repeat examination may be required to show the typical features.

TL;DR: This case series illustrates the harmful effects of ketamine on the urinary tract and the associated radiological findings and it is important that radiologists are aware of this emerging clinical entity as early diagnosis and treatment are essential for successful management.

TL;DR: The use of chest conversion factors significantly underestimates the effective dose when compared to the dose calculated using the ImPACT calculator and a conversion factor of 0.028 would give a better estimation of the effective doses from prospectively gated cardiac MDCT.

TL;DR: The values of ADC, FA, and lambda(i) obtained with DTI could assess subtle structural damage and changes of anisotropy in the cord of cervical myelopathy.

TL;DR: The background, evolution and recommendations of the CT colonography standards document (Appendix) developed by the International CT Colonography Standards Collaboration, which included highly experienced radiologists, radiographers, gastroenterologists, and screening experts are summarized.

TL;DR: The loss of SNR from increasing receiver bandwidth, is preferable to long acquisition times, and therefore, should be the main tool for reducing metal artefact.

TL;DR: CT can be used as an imaging method to identify the ganglion and guide the needle in ganglions impar blockade, especially in cases with anatomical variation in the gangLion impar location.

TL;DR: Measuring the oedema: mass and rCBV ratios of the oEDema surrounding the tumour prior to operation in solitary masses proved to be useful for differentiating metastases from high-grade gliomas.

TL;DR: The typical and atypical appearances of heterotopic pancreas on imaging studies are presented to improve diagnostic accuracy.

TL;DR: A number of techniques have been developed to overcome a phenomenon termed hyperpolarization; these have been used to image tissue pH, cellular necrosis, and to image the lungs.

TL;DR: The present study highlights pancreatic ductal enhancement in a subset of patients with autoimmune pancreatitis, which presented with a variety of CT findings in the pancreas and the extrapancreatic organs.

TL;DR: The role of cross-sectional imaging in the form of magnetic resonance imaging (MRI) and computed tomography (CT) in revealing the spectrum of disease manifestation and differentiation from other disease entities and malignancy will be explored.

TL;DR: The following review presents salient radiological findings of the chest wall and shoulder girdle, thoracic spine, pleural space, and lung in polytraumatized patients.

TL;DR: The concept of spontaneous skull-base CSF leaks and the significance of aberrant arachnoid granulations in imaging these patients are explored and the role of each imaging method is reviewed.

TL;DR: In this paper, the authors illustrate the pathogenesis and imaging findings of tuberculosis in specific head and neck regions to avoid pitfalls in diagnosis, and provide an early diagnosis for extra-pulmonary tubercular lesions in the head.

TL;DR: Another impetus for the development of new tracers is to enable the investigation of biological processes in tumours other than glucose metabolism, where there are new agents that are targeted more specifically at angiogenesis, hypoxia, apoptosis and other processes.

TL;DR: MRI is promising for estimating chronic changes, but cervical radiography may still be needed, as FMD seems to be an important sign of chronicity.
