Congenital heart experts have successfully integrated two common imaging techniques to produce a three-dimensional anatomic model of a patient's heart. This is the first time the integration of computed tomography (CT) and three-dimensional transesophageal echocardiography (3DTEE) has been used in this way. A proof-of-concept study also opens the way for these techniques to be used in combination with a third tool -- magnetic resonance imaging (MRI).

New results in animals highlight a major safety concern regarding a class of magnetic resonance imaging (MRI) contrast agents used in millions of patients each year. The study adds to concerns that repeated use of specific "linear"-type gadolinium-based contrast agents (GBCAs) lead to deposits of the heavy-metal element gadolinium in the brain.

Fructose not only results in a lower level of satiety, it also stimulates the reward system in the brain to a lesser degree than glucose. This may cause excessive consumption accompanied by effects that are a risk to health, report researchers. Various diseases have been attributed to industrial fructose in sugary drinks and ready meals.

A protein encoded by the gene glypican-1 (GPC1) present on cancer exosomes may be used as part of a potential non-invasive diagnostic and screening tool to detect early pancreatic cancer, potentially at a stage amenable to surgical treatment, according to a new study.

A digital map of the aging brain could aid the diagnosis of Alzheimer's disease and other neurodegenerative disorders in older people, a study suggests. The atlas created using images from MRI scans of older people could aid diagnosis by comparing the patients' scans with a detailed map of the healthy aging brain.

A form of 'virtual-reality' therapy may help people with alcohol dependence reduce their craving for alcohol, a new study suggests. The findings come from a small study of just 10 patients. But researchers said they are optimistic about the potential for virtual reality as a therapy for alcohol use disorders.

An annual exam using a key imaging technology could spare patients with lung nodules from unnecessary tests and surgery. The study authors found the imaging technology, called low-dose computed tomography (LDCT), to be a safe and effective screening tool to monitor those with nonsolid lung nodules, which in some cases are precursors to cancer. Lung nodules are small tissue masses in the lungs that can be benign or cancerous.

People who have nonsolid lung nodules can be safely monitored with annual low-dose computed tomography screening, according to a new study. Researchers said the findings could help spare patients from unnecessary surgery and additional imaging.

An agent called PSMA-617 is capable of attaching specifically to prostate cancer cells. This agent can be labeled with various radioactive substances. When chemically bound to a weakly radioactive diagnostic radionuclide, it can detect prostate tumors and their metastases in PET scans. If labeled with a strongly radioactive therapeutic radionuclide, PSMA-617 can specifically destroy cancer cells. A first clinical application of this radiopharmaceutica has now delivered promising results.

Most women -- about 86 percent -- with early-stage breast cancer will undergo imaging to determine if the cancer has metastasized, despite international guidelines that recommend against testing, found a Canadian study.
