Simultaneous PET/MRI most accurate for image alignment
May 20, 2013 -- In a comparison of hybrid imaging modalities, simultaneous whole-body PET/MRI is more accurate than retrospectively fused PET and MR images in abdominal organs and better than PET/CT in the urinary bladder, according to a German study published online on 8 May in Radiology.
Mathias Langer looks ahead to DRK 2013 in Hamburg
May 15, 2013 -- Dr. Mathias Langer will be presiding over the German Radiological Society's annual meeting, the DRK, in Hamburg at the end of this month. In this interview, he sets out details of what visitors to the congress can expect, and explains the many special features awaiting delegates.
Study shows feasibility of cardiac PET/MRI -- with caveats
May 13, 2013 -- Cardiac FDG-PET/MRI is feasible on an integrated whole-body PET/MRI system, but the hybrid modality still must prove it adds clinical relevance to cases of ischemic heart disease, according to a German study published online on 7 May in Radiology.
ECG could replace SPECT MPI for some cardiac patients
May 6, 2013 -- Electrocardiogram (ECG) stress testing alone could be used in place of SPECT myocardial perfusion imaging (MPI) in patients who can exercise at a high capacity, said researchers of a study presented 5 May at the International Conference on Nuclear Cardiology and Cardiac CT in Berlin.
How to merge the best in hybrid imaging
May 6, 2013 -- Datasets in optical and nuclear imaging are being fused with those from other modalities to provide better anatomical information. And in addition to merging PET or SPECT with MRI or CT, the combination of fluorescence molecular tomography with CT or MRI is showing particular promise, a leading German expert said.
Hannover group targets inflammation in cardiac disease
May 6, 2013 -- An established treatment for cancer patients can offer a novel therapeutic approach to decrease the levels of inflammation in the atherosclerotic plaques of patients with cardiovascular disease, German researchers have found.
Second cancer risks warrant rigorous investigation
May 2, 2013 -- How can we estimate the risk of inducing second cancers in patients receiving radiotherapy? Ionizing radiation is known to cause cancer, and the risk of inducing second cancers in patients undergoing radiotherapy cannot be ignored.
Large European dose survey shows low medical exposure
April 29, 2013 -- A pan-European dose estimation project has found that doses administered to patients in medical imaging examinations vary widely by country, but are lower than comparable levels reported for the U.S. and Australia.
FLT-PET could help predict outcome in head and neck cancer
April 9, 2013 -- Change in F-18 fluorothymidine (FLT) uptake on PET during early radiotherapy or chemoradiotherapy is a strong indicator of the long-term outcomes of head and neck cancer patients, Dutch researchers report in the April issue of the Journal of Nuclear Medicine.
Spanish collect top ECR award for work on prostate MRI at 3T
March 18, 2013 -- Diffusion-weighted imaging (DWI) is a powerful noninvasive imaging method that can provide useful qualitative and quantitative information about tumor cellularity and tissue structure in prostate cancer, and permits detecting and staging prostate carcinoma, noted a Spanish team in prize-winning research presented at ECR 2013.
'Unfair' regulatory stance on radiotracers poses threat to PET's future
March 11, 2013 -- VIENNA - Legal and regulatory issues surrounding the production and uses of radiotracers represent a significant threat to PET imaging, a senior luminary told ECR 2013 attendees at Sunday's professional challenges session on the legal matters related to multimodality techniques.
PET/MR shows great potential for detecting multifocal cancers
March 10, 2013 -- VIENNA - PET/MRI allows superior early detection and evaluation of cancers as they disseminate around the body. That was the key message of Dr. Heinz-Peter Schlemmer in his talk in Saturday's new horizons session at ECR 2013.
Ga-DOTATOC PET/MRI tops PET/CT for staging neuroendocrine tumors
March 8, 2013 -- VIENNA - Researchers from University Hospital Essen in Germany have shown the feasibility of whole-body staging of patients with neuroendocrine tumors with PET/MRI and the radiotracer gallium-68 (Ga-68) DOTATOC, and with greater reliability than PET/CT, in a preliminary study presented Friday at ECR 2013.
Collaboration among specialties enhances prospects of cancer patients
March 8, 2013 -- VIENNA - Promoting more effective collaboration among radiologists, nuclear medicine physicians, and radiation oncologists to improve imaging and radiotherapy outcomes is a core principle underpinning the lectures in a special focus session on Friday at ECR 2013.
European experts urge caution on PET/MRI use
March 7, 2013 -- VIENNA - "Hold your horses" was the main message regarding PET/MRI at Thursday's ECR 2013 opening press conference. People may want to quickly adopt the fairly new technique, but Dr. Heinz-Peter Schlemmer of the German Cancer Research Center in Heidelberg urged caution.
