Molecular Imaging

Molecular imaging (also called nuclear medicine or nuclear imaging) can image the function of cells inside the body at the molecular level. This includes the imaging modalities of positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. How does PET and SPECT imaging work? Small amounts of radioactive material (radiopharmaceuticals) injected into a patient. These can use sugars or chemical traits to bond to specific cells. The radioactive material is taken up by cells that consume the sugars. The radiation emitted from inside the body is detected by photon detectors outside the body. Computers take the data to assemble images of the radiation emissions. Nuclear images may appear fuzzy or ghostly rather than the sharper resolution from MRI and CT.  But, it provides metabolic information at a cellular level, showing if there are defects in the function of the heart, areas of very high metabolic activity associated with cancer cells, or areas of inflammation, data not available from other modalities. These noninvasive imaging exams are used to diagnose cancer, heart disease, Alzheimer’s and Parkinson’s disease, bone disorders and other disorders.

Patients at Henry Ford Wyandotte now receive half-dose nuclear medicine imaging

UltraSpect, provider of the only multi-vendor and most cost-effective imaging solution for meeting the American Society of Nuclear Cardiology (ASNC) low dose guidelines, announces today that Henry Ford Wyandotte Hospital in Michigan has upgraded its nuclear medicine (NM) image reconstruction software to UltraSpect Xpress3.Cardiac. As a result, all patients receiving NM exams now have exams in half the time, with half the dose, regardless of the model or age of camera being used.
