Eliminating the need for additional monitors

New displays for different diagnostic images

Displaying medical images from different modalities such as CT, CR/DR, MR, ultrasound or mammography and pathology on one monitor - that is what most radiologists want. Many of them still use several medical displays next to each other. JVCKenwood's new CL-S1200 30.9-inch colour monitor makes this a thing of the past. The 12 megapixel device (4,200 horizontal and 2,800 vertical) can display…

Agfa: Digital Tomosynthesis (DTS) for direct radiography

In clinical practice, planar X-ray images are usually the first imaging technique used. In musculoskeletal imaging, this can be a shoulder in AP and lateral projection. In many of these cases, the 2D technique is not sufficiently informative and further clarification is required, which means additional waiting times or completely new appointments. The DTS allows the diagnostic cycle to be…

Luminescent substance allows accurate viewing of body parts

Researchers have designed a fluid that works like a luminous ink to obtain very sharp images of damaged tissues, organs and cartilages in diagnostic tests. This new compound, still in the laboratory phase, reduces adverse effects on the human body because it allows lower amounts to be injected and the dose to be targeted only at the affected area.

Dual Energy CT – seeing x-rays with colors

Computed tomography (CT) is one of the most important imaging options for the diagnostics of patients. For a long time, in clinical routine CT technology mostly showed the Hounsfield Units (HU) that are indicated in the grayscale. However, the Dual Energy CT (DECT) enables colored X-ray images, therefore significantly improving examination methods. “We can also do material separation and get a…

Radiation protection

Is contact shielding during X-rays, CT scans obsolete?

The British Institute of Radiology (BIR) and a working party of UK radiological professional bodies and agencies have published evidence-based guidance which shows that patient contact shielding (such as aprons, thyroid or gonad shields) provides minimal or no benefit. It concludes that there are other areas of radiation protection which are more effective in optimising radiation exposure such as…

Thyroid cancer and meningioma

Dental X-rays may increase cancer risk

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.
