Cardiovascular magnetic resonance (CMR) imaging has become faster, simpler and more widely available in recent years because it has evolved to deliver effective assessment and diagnosis of a range of heart conditions with expanding guideline indications.
Most people think their heart is located on the left side of their chest, and this is also the direction science has looked, so far. However, just as the heart sits at the centre of the chest, disease also affects the right side of the organ. Cardiologists must now look right to improve patient prognosis, according to Professor José Luis Zamorano, Vice President of the European Society of…
Interventional cardiologists have been aware of the value of intracoronary (IC) imaging in clinical practice for more than twenty years. However, recent developments and improvements in modalities and software have enabled huge strides in its range and scope for both diagnostic assessment and in percutaneous coronary interventions. Imaging options now include intravascular ultrasound (IVUS),…
A research group detected the MRI contrast agent gadolinium in tap water and in cola soft drinks bought in restaurants of well-known fast-food franchises in cities across Germany. Gadolinium appears not to impose any health risk at the low concentrations observed. However, it is an indicator of the potential presence of other waste water-derived, possibly toxic xenobiotics.
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…
On the centenary of his birth, Mark Nicholls reflects on the life and legacy of Nobel laureate Sir Godfrey Newbold Hounsfield, the man who pioneered computed tomography. It was a discovery that came from a moment of inspiration during a country walking holiday; the idea that one could determine what was inside a box by taking X-ray readings at all angles around the object. From that, Sir Godfrey…
Using MRI scans to target biopsies is more effective at detecting prostate cancers that are likely to need treatment than standard ultrasound guided biopsies alone, according to research published in JAMA Network Open. The research, led by the National Institute for Health Research (NIHR) and Universities of Bristol, Ottawa, Exeter and Oxford, combined the results from seven studies covering…
Pathologic-radiologic correlation is already utilised in various settings as a tool to assess the interpretive performance of imaging studies and identify radiologic features corresponding to histologic findings. However, correlative assessment is currently limited mainly to the fields of research and quality assurance, and is generally not a routine element of the radiologist or pathologist…

Prostate-specific membrane antigen imaging should be the positron emission tomography imaging agent of choice for men who have a prostate cancer recurrence after radical prostatectomy, which needs to be detected and located. For these men, it should become the standard of care, new research shows.
In a new study, led by the University of Glasgow, scientists show that brain activity recorded using functional magnetic resonance imaging (fMRI) may help predict response to CBT in depression before the treatment commences. The advances could help patients receive the most appropriate treatment for depression in a timely manner.
For patients with kidney failure who need dialysis, removing fluid at the correct rate and stopping at the right time is critical. This typically requires guessing how much water to remove and carefully monitoring the patient for sudden drops in blood pressure. Currently there is no reliable, easy way to measure hydration levels in these patients, who number around half a million in the United…
