The Institut Curie has renovated its proton therapy centre in Orsay near Paris. Since 1991, when the original centre opened, it has treated over 5,000 patients (4,000 for eye…
Ultrasound is the undisputed choice for foetal imaging. However, the lack of amniotic fluid, an unfavourable foetal position or maternal obesity could daunt even the best radiographer. In such circumstances prenatal magnetic resonance imaging (MRI) – a non-invasive and non-irradiating procedure – is a helpful diagnostic tool.

A few years ago, Dr Peder Bo Nielsen MD FRCPath, Consultant medical microbiologist at Northwick Park Hospital, London, UK, launched a research programme on airborne transmission of nosocomial infections. Until then, so called air-biology held no high priority in infection prevention and control. The prevailing perception was that colonisation and contamination mainly happens due to direct contact…
Oncologists have a dream: they want to use highly energetic ion beams in good quality and accurately defined dose for a pin-sharp and cost-effective radiation treatment of tumors. Modern techniques based on intense laser pulses may in the future replace expensive conventional particle accelerators. A team of physicists of the Cluster of Excellence "Munich-Centre for Advanced Photonics" (MAP) lead…
Cases of hepatocellular carcinoma (HCC), one of the most frequently occurring cancers throughout the world, are expected to increase dramatically in the next 10-15 years in Germany alone. The main reason is the increased occurrence of fatty hepatitis. Thus, in the future, interventional radiologists will also be increasingly involved in HCC patients treatment.

Real-time image guidance during radiation therapy could prove the ultimate means to ramp tumour targeting accuracy and enable real-time tracking of moving targets. MR imaging enables precise soft-tissue visualization with no additional ionizing radiation exposure. Unfortunately, MR systems and linear accelerators are inherently incompatible and some innovative design work is required for them to…
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.
X-rays are made up of high-energy photons. This type of radiation follows the physical laws of electromagnetic waves as well as of particles.
Although there should always be concern about radiation in a facility that uses X-ray to image patients, that concern is perhaps not as vocal as for CT or interventional radiology, according to physicist Jacqueline Gallet, Global Manager of Clinical Studies at Carestream Health.
'An effective, safe treatment for prophylaxis of restenosis in periphery and cardiology' — new generation of Endovascular Brachytherapy gains full CE-certification. Constricted blood vessels (stenosis and restenosis) can now sustainably be treated and kept open through the local treatment with beta radiation.
Mammography is the common way to detect breast cancer. But it's not perfect: it struggles to image dense glandular tissue or early-stage tumours. Magnetic resonance imaging (MRI) offers best sensivity but it is expensiv and not always specific enough. Now researchers have come up with another option: a scanner that integrates thermoacoustic and photoacoustic tomography to achieve dual-contrast…
Prostate cancer is the most frequent cancer in men with about 49,000 newly diagnosed cancers in Germany and 6,000 in the Netherlands, annually.
Molecular imaging aims at the in vivo quantitative visualisation of molecules and molecular events that occur at cellular level. The potential towards clinical translation is huge, because the same modalities used in medical imaging are used in molecular imaging investigations.
By Rudolf Schwarz and Andreas Krüll, of the Section of Radiation Oncology Department, Ambulanzzentrum GmbH of the University Medical Center Hamburg-Eppendorf
Traditionally, radiography systems have an X-ray tube at one end, film-screen cassette or detector at the other, a table between, and perhaps a mounted assembly on a U-arm or chest stand.

Optical imaging stands on the threshold of a vast array of imaging uses, writes Professor Eric N C Milne MD FRCR FRCP, Professor Emeritus of Radiology and Medicine, University of California Irvine, and Director of Clinical Research, Imaging Diagnostic Systems Inc. `Presently, its greatest worth lies in higher sensitivity for the dense breast. It detects many more occult cancers than conventional…
Melatonin hormone controls the circadian rhythm. In periods of darkness, melatonin reduces cardiovascular activity and induces fatigue. Morning light inhibits melatonin secretion in the pineal gland, which increases cardiovascular activity.
Ballon Brachytherapy and effective drug combination.
Prostate cancer, the most common neoplasm in men, often progresses from an androgen-dependant state (and is commonly treated by androgen ablation therapies) to a hormone-refractory stage, therefore making hormone therapy ineffective. The response duration to androgen ablation therapy is finite and ultimately most prostate cancer will become hormone-insensitive.
