Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

FDA Approves Popular European MRI Contrast Agent Dotarem

The U.S. Food and Drug Administration (FDA) has approved Dotarem (gadoterate meglumine) as the first macrocyclic and ionic gadolinium-based contrast agent (GBCA) that can be used in the United States

Other side of the coin: CT has advantages over SPECT for detection of stable CAD

In a companion piece that counters an opinion that SPECT is the best modality for first-line detection of CAD, separate experts argued that CT finds sub-clinical atherosclerosis and important coronary anatomy, providing earlier diagnoses and the option to be more aggressive with treatment, according to a review published April 10 in the Journal of Nuclear Cardiology.

Correction: Amyvid makers call for CMS coverage of amyloid imaging

The article "Amyvid makers call for CMS coverage of amyloid imaging," has been revised.

SPECT beats CT for detection of stable CAD

Some clinicians maintain that cardiac-computed tomography angiography (CCTA) bests SPECT/CT for the detection of CAD, but two expert nuclear cardiologists suggest the opposite and presented data to demonstrate their case, in a study published April 10 in the Journal of Nuclear Cardiology.

Algorithm delivers quantitative F-18 FDG PET partial volume correction

The use of algorithms is changing the game for close-as-possible assessment of tumor volume and resolution recovery from PET cancer imaging, especially small objects affected by partial volume effects. Researchers conducting phantom studies have optimized quantitative tumor delineation of F-18 FDG PET imaging with two specialized algorithms that provide accurate partial volume correction for volumes as small as one-third of a milliliter, according to research published May 8 in the Journal of Nuclear Medicine.

Varian Gets FDA OK for New X-Ray Workstation

The FDA has granted 510(k) clearance to Varian Medical Systems Nexus DRF Digital X-Ray Imaging System. The new diagnostic X-ray image processing workstation combines radiography/fluoroscopy (RF) and digital radiography (DR) capabilities on one platform

GE Healthcare MR Technique Improves Accuracy for Imaging Joint Replacements and Implanted Devices

Addressing the need for better imaging of tissue surrounding metal-containing implants such as joint replacements, GE Healthcare and researchers at the Hospital for Special Surgery in Waukesha, Wis., designed and tested a novel MR imaging technique that cuts down on the image distortion caused by metal in implants

Can Molecular Imaging Usher in Personalized Medicine?

I have been struggling recently with the notion that genomics is going to revolutionize our ability to diagnose and treat disease. Why? A basic tenet of information theory is simple: the more precisely you can measure something, the less information it contains.
