New health technologies require development and evaluation ahead of being incorporated into the patient care pathway. In light of the recent publication by Lehoux et al who discuss the role of entrepreneurs, investors and regulators in providing value to new health technologies, we summarise the processes involved in making new health technologies available for use in the United Kingdom.

Objectives: A national survey was designed to better understand factors influencing special interest choices, future aspirations of UK radiology trainees and perceptions of breast radiology.

Methods: A SurveyMonkey questionnaire was developed and distributed to all radiology trainees in the UK through the British Institute of Radiology, RCR Junior Radiologists Forum and by directly contacting UK training schemes as well as by social media between December 2015 and January 2016.

Results: From 21 training schemes across the UK, 232 responses were received.

May-Thurner syndrome (MTS) is a rare condition in which patients develop iliofemoral deep venous thrombosis due to an anatomical variant in which the right common iliac artery overlies and compresses the left common iliac vein against the lumbar spine. We report a case of variant MTS, where vascular distortion secondary to spontaneous spinal arthrodesis of degenerative lumbar spondylolisthesis resulted in left common iliac vein compression and iliofemoral deep vein thrombosis. While the common complications of degenerative spondylolisthesis, such as spinal stenosis, are well described; the potential for pelvic vascular distortion secondary to anterior translation of the lumbar spine is not well recognized.

Prostate cancer is the second most prevalent cancer in males worldwide and the commonest cancer in males in the UK. The recent updates on the diagnosis and treatment of prostate cancer were discussed at a multidisciplinary day event organized by the British Institute of Radiology and held in London in November 2016. This day covered the use of the prostate-specific antigen biomarker and of advanced imaging techniques such as multiparametric and whole-body MRI, choline positron emission tomography/CT and gallium-labelled prostate-specific membrane antigen for the detection of prostate cancer.

Article Synopsis
  • - The study compares two reconstruction methods for analyzing PET/CT data in detecting colorectal liver metastases, focusing on a Bayesian penalised likelihood (BPL) algorithm versus a conventional time-of-flight ordered subsets expectation maximisation (OSEM) approach.
  • - Results show that using the BPL algorithm significantly increases the maximum standardized uptake value (SUVmax) of lesions and improves the signal-to-background ratio (SBR) and signal-to-noise ratio (SNR) without raising background noise levels.
  • - The findings suggest that the BPL algorithm enhances the detectability of FDG-avid liver lesions, potentially aiding in better diagnosis of such conditions.

Obesity is a growing epidemic, and current medical therapies have proven inadequate. Endogenous satiety hormones provide an attractive target for the development of drugs that aim to cause effective weight loss with minimal side effects. Both glucagon and GLP-1 reduce appetite and cause weight loss.

There have been repeated calls from all quarters of healthcare for more clinicians to be leaders. The risks of not accepting this responsibility have been demonstrated by harrowing reports into failed care in England. Ambiguity persists over what clinical leadership encompasses, how it can be developed and how to inspire clinicians to practise it.

In recent times, there has been an unprecedented level of public interest and active debate regarding the regulation of medical devices. This is in light of the topical, rather dissimilar, incidents involving poly-implant-prothèse (PIP) breast and metal-on-metal hip implants. Although medicines and devices are regulated under European Union (EU) law, the regulatory regimes are very different and some have argued that features of the pharmaceutical regime should be applied to medical devices in the current review of the medical devices directives.

In the 21st century, the core skills of trainee doctors are evolving as clinicians, leaders and innovators. Leadership skills are an essential tool for all doctors and need to be an integral part of their training and learning as set out in the General Medical Council's Good Medical Practice. It is essential to develop these skills at an early stage and continually improve them.

A best evidence topic in vascular surgery was written according to a structured protocol. The question addressed was whether the use of intraoperative cell-salvage (ICS) leads to negative outcomes in patients undergoing elective abdominal aortic surgery? Altogether 305 papers were found using the reported search, of which 10 were judged to represent the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated.

An 81-year-old female presented to the maxillo-facial department with a 6-month history of left-sided toothache and upper lip and cheek numbness. She had previously undergone a right mastectomy for breast adenocarcinoma, followed 6 years later by left mastectomy with pneumonectomy for contralateral breast and lung metastases. Following buccal biopsies and MRI of the head and neck, the patient was referred to our head and neck team.
