Bringing diagnostics and therapy closer together - that is the basic concept behind theranostics. Through further development of its PET/MR scanners, Siemens Healthineers aims to advance this approach. Andreas Schneck, Head of the MRI Division at Siemens Healthineers, talks about the new system, which was also presented at the European Congress of Radiology (ECR) in Vienna, and its advantages in…
Using an advanced PET scanner, US radiologists explore how cancer, neurodegenerative diseases and other systemic conditions, can affect the brain by assessing the impact on the blood-brain barrier.
Using the COX-2 enzyme, a new PET imaging approach offers a never-before-seen view of inflammation in the brain, opening the door for clinical and research settings for various brain disorders.
Researchers have identified biomarkers that, in conjunction with PET imaging, enable doctors to reliably distinguish between primary 4-repeat tauopathies and Alzheimer's disease.
A new type of contrast agent for use in both MRI and PET imaging has the potential to significantly enhance diagnosis and subsequent treatment, particularly for kidney diseases and tumors.
In some patients with multiple sclerosis (MS), symptoms worsen during treatment, but MRI scans do not indicate any change. In such cases, positron emission tomography could help, a new study suggests.
A combination of PET and MR imaging could help doctors spot signs that breast cancer is beginning to spread in a patient. This insight can then be used to adapt treatment strategies.
Breast cancer has no “one size fits all” therapy approach: subtypes differ significantly in malignancy, progression, and treatment response. Therefore, the more is known about the type of carcinoma in a patient, the better the outcome. At the annual scientific EUSOBI meeting in Valencia, Dr Ramona Woitek pointed out the potential of novel imaging techniques and computational image analysis…
Advances in positron computed tomography (PET) could lead to a more refined approach to the precise removal of brain tumors is on the horizon, experts from Poland point out.
A novel nuclear medicine imaging protocol can take the place of two separate imaging scans for the evaluation of brain changes linked to cognitive impairment.
In men recently diagnosed with intermediate or high-grade prostate cancer, PSMA PET/MRI can successfully determine whether their cancer is likely to return within two years of a prostatectomy.
AI-based models for multimodality hybrid imaging have the potential to be a potent clinical tool but are currently held back by a lack of transparency and maturity, says Dr Irène Buvat, from the Laboratory of translational Imaging in Oncology, Institute Curie in Paris, France.
PET/MRI is offering new imaging opportunities for cancer patients at various points along the care pathway with its ability to assess different biological processes and its increased specificity.
The effects of Covid-19 on the brain can be accurately measured with positron emission tomography (PET), according to research presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2021 Annual Meeting. In the study, newly diagnosed Covid-19 patients, who required inpatient treatment and underwent PET brain scans, were found to have deficits in neuronal function and…
Tumour metabolism can be imaged with MRI as a technique to help determine cancer aggressiveness and response to therapy. The work by a UK-based group, on probing cancer metabolism non-invasively with clinical hyperpolarised carbon-13 MRI, can detect metabolic changes in the tumour. As metabolic changes occur much earlier than change in tumour size, this could have implications for quicker…
Former ESR President Katrine Riklund will explore the clinical applications of hybrid imaging in a virtual session for the European Congress of Radiology 2020. She will discuss a number of common indications of hybrid imaging in areas of oncological diagnosis, the indications and limitations of hybrid imaging in common diseases, and the added value of hybrid imaging. “The major benefit of…
Brain imaging of pathological tau-protein “tangles” reliably predicts the location of future brain atrophy in Alzheimer’s patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center. In contrast, the location of amyloid “plaques,” which have been the focus of Alzheimer’s research and drug development for decades, was found…
Whole-body magnetic resonance imaging (WB-MRI) is championed as offering significant benefits, such as improving disease evaluation for prostate cancer patients. During an intense session in genito-urinary cancer at ECR 2019, three key speakers focused on the advantages over conventional imaging modalities as well as discussing new PET (Positron Emission Tomography) tracers.
During a European Society of Hybrid, Molecular and Translational Imaging (ESHI) session at ECR 2019, three speakers discussed the role of artificial intelligence (AI) in hybrid imaging. While AI and machine learning is supporting clinicians using hybrid techniques such as PET/CT, MR/PET, or ultrasound and CT, challenges remain in ‘training the machines’ to add value to radiologists’ and…
