Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis, offers a significant advance in using magnetic resonance imaging (MRI) to pick out even very small tumors from normal tissue. The work is published in the journal Nature Nanotechnology. Chemical probes that produce a signal on MRI can be used to…
A group of researchers led by Leif Schröder from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have found a way to detect metastases in certain types of cancer in the brain at an early stage, using only minimal amounts of contrast agent. To this end, the team uses a synthetic molecule that helps to detect the formation of new blood vessels, producing much more sophisticated…
MRI is now indispensable for diagnosing diseases and monitoring therapies. However, the ongoing discussion on gadolinium deposits in the brain has intensified the search for alternatives. Dr Daniel Paech of the German Cancer Research Centre in Heidelberg, Germany, discussed potential solutions to acquire high-quality images without contrast agents.
It has been found in many rivers and even in the tap water in some German cities, now scientists detected gadolinium from contrast agents in the food chain. A research group headed by Michael Bau, Professor of Geoscience at Jacobs University Bremen, detected the gadolinium in tap water and in cola soft drinks bought in restaurants of well-known fast-food franchises in Berlin, Dresden,…
Traditional MRI (magnetic resonance imaging) scans use the metal gadolinium, which resonates areas of the heart muscles that are not functioning efficiently. However, gadolinium affects the Kidney function. A new 3D MRI computing technique developed by scientists at the University of Warwick calculates strain in heart muscles showing which muscles are not functioning enough without damaging other…
The pros and cons of CT (computed tomography), MRI (magnetic resonance imaging) and CEUS (contrast enhanced ultrasound) for emergency abdominal use were highlighted by speakers in an ECR 2019 session under the broader heading: ‘Abdominal Emergencies: advanced imaging in daily routine’.
Researchers are using artificial intelligence to reduce the dose of contrast agents like Gadolinium that may be left behind in the body after MRI exams, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).
Contrast enhanced ultrasound (CEUS) has proved in trials to be more accurate than computed tomography and MRI and can help eliminate the need for unnecessary biopsies and surgery. Dr Richard Barr, Professor of Radiology at Northeast Ohio Medical University, explains the benefits of the modality.
Gadolinium-containing/gadolinium-based contrast agents (GCCAs/GBCAs) and their usage was a major topic at ECR 2018. Fuelled by the current debate a number of presentations focused on possible impact, risks and necessities. Some were highly specific, others took a broader view. The only consensus, however, seems to be the need for more research and the focus on safety. Three ECR speakers, Joseph…
The European Medicines Agency (EMA) decided to suspend authorisation for certain linear gadolinium agents. The review by the Committee for Medicinal Products for Human Use (CHMP) states: “There is currently no evidence that gadolinium deposition in the brain has caused any harm to patients; however EMA has recommended restrictions and suspensions for some intravenous linear agents in order to…
Radiologists must ensure precise scientific data and radiology-based evidence are used to regulate the use of Gadolinium Containing Contrast Agents (GCCAs), a Spanish leading radiologist explained in closed-door leadership meeting earlier this year in Barcelona.
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…
In April 2016 CEUS received the USA’s FDA approval. This year‘s RSNA Samsung Symposium ‘Contrast-Enhanced Ultrasound (CEUS): Innovations and a Problem-Solving Tool in Clinical Practice’ provided an opportunity to take stock. For European Hospital, Professor André Clevert, Director of the Interdisciplinary Centre for Ultrasound at University Hospital Munich, Germany, describes the current…
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…
The ability to demonstrate blood perfusion as well as organ function using contrast agentenhanced ultrasound is quickly finding innovative uses in clinical practice. Contrast-enhanced ultrasound (CEUS) has advanced rapidly since its first introduction. Today it is widely used as a primary imaging technique for a number of indications and pathologies. At a symposium organised by Bracco Imaging…
A new magnetic resonance imaging (MRI) contrast agent being tested by researchers at Case Western Reserve University not only pinpoints breast cancers at early stages but differentiates between aggressive and slow-growing types.
Scientists from the German Cancer Research Center (DKFZ), in collaboration with colleagues from Heidelberg University Hospital, have been able to visualize brain cancer using a novel MRI method. They use a simple sugar solution instead of conventional contrast agents, which can have side effects in the body.
Gadolinium-based contrast agents are an essential component of MRI exams, but are challenged by findings of residual depositions of gadolinium in the body, even though the clinical relevance remains unknown. Three clinicians described how changes to MRI protocols and dose levels for contrast media can optimise the balance between benefit and risk for patients and radiologists.
