Useful, not pretty: How AI can improve medical imaging

US researchers evaluated AI techniques for cleaning medical images based on performance in clinical tasks. Some algorithms make the scans look better, but actually decrease image quality.

SPECT/CT improves diagnosis of indeterminate kidney tumours

99mTc-Sestamibi SPECT/CT can aid in the diagnosis of solid renal lesions, especially in cases where contrast enhanced CT findings are inconclusive, according to researchers from the Mallinckrodt…

Molecular imaging uncovers effects of Covid-19 on the brain

A significant number of Covid-19 neurological complications – such as fatigue, headache, and cognitive impairment – are ultimately reversible, according to new research.

Unfolding new vistas for MRI, PET and PET/CT

The importance of cardiac imaging is increasing, but nuclear medicine procedures are by no means obsolete, observes Okan Ekinci, during our EH interview with the Siemens Vice President for Healthcare…

New imaging for ischaemic heart disease

A session at the forthcoming British Cardiovascular Society annual conference (2-4 June, in Manchester) will hear about the latest imaging techniques for acquired heart disease, with PET technology…


Dual energy brings more to meet the eye

How does spectral – or dual energy – imaging work? Very similar to red and green light used in black-and-white photography. A black-and-white camera provides information on the colours of the photographed objects: an object that is black under red light is actually green.


Toshiba presents advances in Cardiac Imaging at ESC 2012

Cardiology is playing an increasingly important role in today’s healthcare environment and, as a direct result, cardiologists are facing new challenges almost every day. Addressing the need of improving clinician confidence and diagnostic accuracy, Toshiba Medical Systems Europe presented two symposia on the first day of the European Congress of Cardiology, to be held in Munich, Germany, 25-28…


CT and PET - Improving radiation therapy planning

When planning radiotherapy the combination of positron emission tomography (PET) and Computed tomography (CT) can provide a better outcome than CT alone. Michael Krassnitzer asked Terri Bresenham MSc BSc, Vice President for Molecular Imaging at GE Healthcare, for her views on the value of PET/CT, the new EANM guidelines, novel tracers and the future of other hybrid imaging technologies.


Molecular imaging in clinical practice

Over the past decades new imaging technologies have substantially broadened the range of imaging applications in clinical medicine. For years anatomical imaging modalities, such as X-ray and CT, reveal high-resolution information of organs and tissues over extended imaging ranges. Lately, however, the idea of functional imaging e.g. the visualisation of physiology in vivo gains importance.

Imaging and computing power leading to breakthroughs for cardiac surgery

Two members of the Heart Center at the University of Leipzig teamed up during Medica for a tour de force presentation on Future Trends in Cardiac Surgery. "The aim of the game is opening the chest through little keyholes to operate in the most minimally invasive way possible and avoid sternotomy," said Prof. Friedrich Mohr, Program Director at the Leipzig Heart Center, who review new surgical…

Imaging Crucial for personalized medicine

'Personalized medicine' -- where therapy is designed for the individual patient -- is a popular concept in healthcare today, but according to a new market research report, it will be driven by the imaging industry, especially the new molecular technologies. If images can reveal not just the heightened metabolic activity characteristic of tumors but the tumors' chemical signatures, physicians can…

Role of New Software and Technology

In the last fifteen years, myocardial perfusion SPECT imaging (MPI) has been performed most commonly by dual-head conventional scintillation cameras with parallel-hole collimators, configured in a 90ºdetector geometry and image reconstruction based on standard filtered back projection (FBP) algorithms. Such arrangement, although clinically well established suffers from important limitations…


GE's new Discovery PET/CT 600 scanners go global

GE Healthcare's first Discovery PET/CT 600-series scanners are being installed in a number of leading clinics around the world. "This first set of installations is a big step forward in the diagnosis and monitoring of disease", said Terri Bresenham, newly appointed vice- president and general manager of GE Healthcare's global Molecular Imaging business.


Diagnosis of Cardiac Diseases

For decades, non-invasive cardiac assessment has been at the center of interest. Non-invasive imaging modalities, such as MSCT, MRI, SPECT, PET, and echocardiography, provide valuable cardiac information, and all have been used to measure cardiac morphology, function, perfusion, viability of myocardium, and coronary anatomy for clinical management and research. The last decade brought major…
