Breast cancer: how imaging technology will help avoid unnecessary biopsies

Enhancing the diagnosis of breast cancer is the stated goal of a research team at the German Cancer Research Center (DKFZ) in Heidelberg. The scientists have combined an advanced method of diffusion-weighted MR imaging with intelligent image analysis methods to detect malignant changes in tissues. This method may help avoid many control biopsies following suspicious findings from mammography…

Manganese or gadolinium?

Promising first steps for alternative MRI contrast agent

NIH-supported researchers at Massachusetts General Hospital (MGH) are studying an alternative to the contrast agents currently used for magnetic resonance imaging. In a recent study, they showed that the experimental alternative, a manganese-based compound, performs as well as approved contrast agents. Their study appeared online in Radiology. Magnetic resonance (MR) images are taken so that a…

The birth of psychoradiology

The emerging field of psychoradiology is taking a major step ahead. A new study highlights MRI’s role in identifying people with attention deficit and hyperactivity disorder (ADHD) and classifies subtypes of the condition, a leading Chinese researcher explained at the ESMRMB annual meeting.

State-of-the-art MRI technology bypasses need for kidney biopsy

The most common type of tumor found in the kidney is generally quite small (less than 1.5 in). These tumors are usually found by accident when CAT scans are performed for other reasons and the serendipitous finding poses a problem for doctors. Are these tumors malignant and do they need to be surgically removed because they may threaten the patient’s life? Or are they benign and can be left…

Contrast-enhanced digital mammography vs. breast MRI

Contrast-enhanced digital mammography is comparable to breast MRI in evaluating residual breast cancer after neoadjuvant endocrine therapy or chemotherapy, according to the results of a study presented by Mayo Clinic researchers at the 2017 San Antonio Breast Cancer Symposium. “Our study aimed to compare contrast-enhanced mammography with breast MRI in evaluating residual breast cancer in…

Raising the bar higher in CRC imaging

Combining molecular information and high contrast resolution may well improve current performance in colorectal cancer (CRC) cases, according to Vicky Goh, who presented the latest results on PET/MRI during the last European Society of Medical Oncology (ESMO) meeting in Madrid PET/MRI brings the best of both modalities together: high contrast to noise and high spatial resolution combined with…

GOKnee3D: Siemens boosts MRI productivity with new application

During the Annual Meeting of the Radiological Society of North America (RSNA), held in Chicago, USA, Siemens Healthineers presents an innovative MRI application that helps to shorten the time it takes to perform comprehensive diagnostic exams of the knee. At the moment, a standard knee examination could take around 20 minutes. With GOKnee3D, a high-resolution diagnostic 3D knee exam can be…

Mapping brain connectivity with MRI may predict cardiac arrest survival

A new study led by Johns Hopkins researchers found that measures of connectivity within specific cerebral networks were strongly linked to long-term functional outcomes in patients who had suffered severe brain injury following a cardiac arrest. A description of the findings, published in October in the journal Radiology, suggests that mapping and measuring such connectivity may result in highly…

Risk profiling in breast diagnostics

Breast diagnostics are undergoing considerable change, with new technology facilitating alternative procedures. Genetics and nuclear medicine also enhance diagnostic possibilities. During our EH interview, Professor Rüdiger Schulz-Wendtland described current changes in breast diagnostics. ‘To date, complementary breast diagnostics has comprised clinical, sonographic and mammographic…

Seeking a view through the dense breast

Despite rigorous quality assurance of breast cancer screening programs, ‘both, over- and under-diagnosis of breast cancer is a challenge,’ says leading radiologist Christiane K Kuhl, from the Department of Diagnostic and Interventional Radiology, at the University of Aachen, Germany. ‘Mammography is a good screening test – but has its limitations especially, but not only, in women with…

EUSOBI 2016 Annual Scientific Meeting breast imaging session

‘The best way to screen’

The European Society of Breast Imaging (ESOBI) promotes high quality breast imaging across Europe by developing education and training, encouraging research and promoting guidelines and standards. This year’s meeting (23-24 September) was held in collaboration with the French Society La Société d’Imagerie de la Femme (SIFEM) and drew around 600 radiologists. The event included a two-day…

Superior to contrast CT for evaluating some here-and-gone metastases

MRI enhanced with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid -the scan referred to as “EOB MRI” - is significantly better than contrast-enhanced CT for assessing colorectal liver metastases that disappear after chemotherapy, according to a study published online March 22 in Radiology.

MRI leading the way in metabolic disease imaging

New MRI techniques are set to offer advances in the earlier detection of liver disease in patients. Radiologists are harnessing the potential of highly-targeted MRI, whilst exploring the imaging modality as a means of delivering non-invasive biomarkers, reducing the need for biopsy to measure treatment response.

Simpler MR-conditional cardiac device selection

The ProMRI Configurator made by Biotronik is an online tool that enables physicians to select from a series of MRI requirements for a patient and subsequently generates a recommendation of all suitable MR-conditional cardiac device and lead combinations available in a particular country, thus helping physicians to choose the most suitable MR-conditional cardiac systems for each patient.
