Regulators Work With Medical Industry on Radiation Protection

Putting patient safety first is a priority for both HERCA, the association of the Heads of European Radiological Protection Competent Authorities and COCIR, the European trade association representing the medical imaging, electromedical and healthcare IT industry, who are working together to address concerns related to radiation exposure in computed tomography (CT).

The BRANSIST alexa

The multipurpose BRANSIST alexa, which aims to provide total support for advanced catheterisation procedures, features a 12 x 12-inch flat panel detector (FPD) – an ideal size, the manufacturer Shimadzu points out, for covering interventions from head-to-toe, from brain blood vessels, cardiac and abdomen to peripheral blood vessels in the upper and lower extremities.

Researchers Use CT to Recreate Stradivarius Violin

Using computed tomography (CT) imaging and advanced manufacturing techniques, a team of experts has created a reproduction of a 1704 Stradivarius violin. Three-dimensional images of the valuable violin and details on how the replica was made were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Integrated 3-D Imaging Facilitates Human Face Transplantation

By combining conventional medical imaging with some of the same 3-D modeling techniques used in Hollywood blockbusters, researchers are offering new hope to victims of serious facial injuries. Results of a new study on human face transplantation, led by Darren M. Smith, M.D., plastic surgery resident at the University of Pittsburgh Medical Center (UPMC), were presented today at the annual meeting…

For U.S. Adults, Medical Imaging Awareness Brings Clarity to Critical Healthcare Decision-Making

Amid increased scrutiny over medical imaging scans and the use of radiation, a new survey reveals that awareness and familiarity with medical imaging tests lead to clearer decisions for U.S. adults about their healthcare. The survey, released by the Siemens Radiation Reduction Alliance (SIERRA) – an expert panel established to advance the cause of dose reduction in medical imaging – evaluated…

Web-based education in dose reduction in radiology and nuclear medicine

Siemens Healthcare is the first medical engineering company to offer a Low Dose Information Center on the Web. This English-language platform for continuing education and information around the topic of dose reduction is aimed at doctors and clinical personnel. The range of topics covered includes basic information on X-ray radiation, technical innovations relating to dose reduction and sample…

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.
