Image guided radiation therapy

Following the acquisition of an Elekta Axesse system, which provides 3-D image guidance technology for conventional and stereotactic radiation therapy techniques, Helsinki University Central Hospital (HUCH) in Finland reports that, after eight months its image guided radiation therapy (IGRT) of lung, brain, pelvis, head and neck tumours has increased by up to 30 patients daily.

CT, PET-CT, MRT and transthoracic ultrasound in lung cancer staging

Dr Helmut Prosch, at the University Clinic for Radio-Diagnostics, Vienna, Austria, is examining the role of imaging in lung cancer diagnosis and staging. The key message of his presentation in the session EUS and EBUS vs. CT, MR and PET-CT in the staging of lung cancer is that the modalities do not compete with one another – as the title suggests – but are perfectly complimentary in the…

Growing Demand for Postmortem Imaging

Postmortem examination by means of computed tomography and other imaging techniques is still a novelty in many countries. But at the forensic institute of the University of Zurich, Switzerland, scanning the bodies is daily routine. By Irène Dietschi

Contrast enhanced tumour studies

Medical imaging has recently advanced so rapidly that it should halt. Applying more power to computed tomography (CT) and magnetic resonance imaging (MRI) scanners is becoming too dangerous for patients and healthcare workers. Magnets for the next-generation MRIs are so powerful that they must be moved to a separate building on hospital campuses, while CT radiation levels have risen to alarming…

CT is set for a vital role in cardiology

Computed tomography (CT) is emerging as an imaging modality set to play an important role in cardiac intervention or surgery. Not only can it be used to plan complex revascularisation procedures and assess the outcome for the patient, but also might help to identify the more dangerous lesions -- so-called ‘culprits’ -- in the future.

Old technology in new outfit

Looking at the 5th dimension of a CT image is old hat. Back in the 1980s there were many installations with rapid kV switching, a dual energy procedure, which were mainly used for bone density measurements. Basically, the 5th dimension is the ability to determine the atomic number as well as density of materials, which facilitates tissue differentiation even when there is the same attenuation.

Imaging and stroke

USA - Although it is well know that the speed of diagnosis and treatment for stroke victims is of paramount importance (4.5 hours), not all US hospitals have stroke expertise. The Joint Commission, the organisation responsible for accrediting US non-government hospitals, has certified only about 500 out of several thousand hospitals as primary stroke centres.

Biomarkers - the hallmark of personalised medicine

"One size fits all" – the phrase is a fact of life in terms of the drugs available to treat cancer patients today. This solution can bear tragic results. Only 25% of cancer patients currently respond to this ‘one size’ drugs administration. In addition, 100,000 patients die annually, in the USA alone, from the side effects of those drugs. Personalised therapies that are devised to suit…

Meaningful Innovations: Ingenuity CT and Ingenuity TF PET/CT

During RSNA, Philips announced the new Philips Ingenuity CT platform, an innovative technology that will help redefine low dose imaging. The Ingenuity CT features iDose4, Philips’ next-generation iterative reconstruction technique, designed to provide equivalent diagnostic image quality at up to 80 percent less dose; improve spatial resolution by up to 35 percent with up to 50 percent less…

CT and PET - Improving radiation therapy planning

When planning radiotherapy the combination of positron emission tomography (PET) and Computed tomography (CT) can provide a better outcome than CT alone. Michael Krassnitzer asked Terri Bresenham MSc BSc, Vice President for Molecular Imaging at GE Healthcare, for her views on the value of PET/CT, the new EANM guidelines, novel tracers and the future of other hybrid imaging technologies.

The economic value of PET-CT - a scenario-based analysis

PET/CT is an established clinical tool especially for cancer-related diagnosis. This involves both initial diagnosis and follow-up examinations. There are other procedures, like CT/MRT, bone scan, or mediastinoscopy, all of which are also costly. Given the fact that PET/CT is widely used anyway, the question arises whether it is medically responsible and financially favourable to focus solely on…

Diffusion weighted whole body MRI

Malignant diseases rank second in mortality rates in Germany. These patients thus receive a major proportion of ambulant and hospital care, with apparent socioeconomic consequences. To optimise treatment planning, for all solid tumour entities it is mandatory to delineate or stage the primary extent of tumour invasion and spread prior to therapy as precisely as possible.

Investigating sports injuries

Radiologist Dr Karl-Friedrich Schünemann works in a group* practice in the small German city of Paderborn. Focusing on sports injuries and using MRI, CT and X-ray, the specialist medical team provides services such as neuroradiology, orthopaedics and CT-guided pain therapy. ‘The fact that we count a number of professional athletes among our clients also attracts many amateur athletes who…

Aortic valve replacement in the third dimension

No white lab coats anywhere; instead men in hard hats, equipped with hammers and drills. The Düsseldorf University Hospital’s Cardiology Pneumology and Angiology Clinic is a construction site, but once the workmen have packed up their tools and removed the scaffolding the view to the human heart will be unobstructed and clearer than ever before. Here, innovative patient care and a highly…
