Against a backdrop of changing technology and reduced patient dose, a new momentum is emerging within radiology to eradicate patient shielding. The subject has been extensively debated and researched in recent years but there is now a growing consensus to end the practice, apart from with a few exceptions. The topic was the focus of a session at ECR 2023 in Vienna where different perspectives…
Researchers from the Organoid group (Hubrecht Institute) and UMC Utrecht have developed a biobank with organoids derived from patients with head and neck cancer (HNC).
Radiation exposure in diagnostic and interventional radiology is steadily being reduced, but some important parameters have hardly been taken into account so far, says Dr Kerstin Jungnickel. The medical physics expert explains how patient-specific protocols can improve radiation protection and outlined new findings on the radiosensitivity of certain body regions and their impact.
Researchers have succeeded in using metal oxide nanoparticles as "radiosensitizers" – and in producing them on an industrial scale.
A radiotherapy technique which ‘paints’ tumours by targeting them precisely, and avoiding healthy tissue, has been devised in research led by the University of Strathclyde. Researchers used a magnetic lens to focus a Very High Electron Energy (VHEE) beam to a zone of a few millimetres. Concentrating the radiation into a small volume of high dose will enable it to be rapidly scanned across a…
Royal Philips announced the ultimate ultrasound solution for pediatric assessment, the latest addition for its Philips Ultrasound System (EPIQ Elite). The new ultrasound solution provides clinicians with exceptionally detailed images and the performance they need to make a definitive diagnosis for pediatric patients, reducing the need for additional diagnostic imaging steps, such as X-ray imaging.
Research by team at Brighton and Sussex Medical School (BSMS) showed that repeated exposures to dental X-rays may be associated with an increased risk of thyroid cancer and meningioma. About 3,500 new cases of thyroid cancer and 1,850 cases of meningiomas are diagnosed each year in the UK, and the incidence of both cancers has increased in many countries during the past three decades.
Suspicion of venous thromboembolism (VTE) in a pregnant patient will quickly bring a radiologist to a choice, where the next step holds potentially significant consequences for both the mother and unborn child.
Imaging of the chest is the most common radiological examination worldwide. With the incidence of respiratory problems and lung cancer growing, all radiologists should be familiar with the appropriate imaging protocols. In a field dominated by chest x-ray (CXR) and CT, controlling radiation dose is mandatory.
Making prostate cancer therapy more effective, more comfortable for patients and less expensive for society? Dose escalation, up to 80 Gy and above, may be necessary to successfully treat localised prostate cancer with radiotherapy (RT).
An examination of the world-wide use of hematopoietic stem cell transplantation (HSCT), which involves transplantation of blood stem cells derived from the bone marrow or blood, finds that there are significant differences in transplant rates between countries and continental regions by indication and donor type, and that HSCT is most frequently used in countries with higher gross national…
Depending on the institution, CT examination doses can vary dramatically by a factor of ten, said Professor John Damilakis, PhD, associate professor at the University of Crete, Iraklion, ahead of the session. The difference is related principally to variations in the examination technique, as the protocol or the imaging system itself determines the level of radiation.
Most professionals will recognise issues that call for consideration in a wider context, a context that does not merely consider strictly professional issues, i.e. issues based upon facts and figures, write Johannes Gossner MD and Joerg Larsen MD FRCR, of the Institute for Roentgendiagnostics, Braunschweig Teaching Hospitals, Germany.
Fighting breast cancer is always a race against time - early detection of breast carcinoma an essential condition for cure. Now Scientists from Finland, Germany and France developed a promising new CT technique with high resolution and contrast that visualises tumours that are even diffusely growing or those in dense breasts.
