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. 

Northwestern to Install U-SPECT/CT for Cross-Disciplinary Biomedical Studies

A U-SPECT+/CT (MILabs, The Netherlands) will be installed at Northwestern University (Chicago, IL) to deliver ultra-high resolution, high sensitivity, accurate quantification and fast scanning speed of dynamic radio-labeled molecule distributions, contributing to molecular and functional studies in CNS, cardiovascular, oncology, nephrology and reproductive biology.

Immunotherapy could clear out cervical cancer

T cell immunotherapy prompted a striking response from three out of nine women with advanced cervical cancer, including one who had extensive metastases, according to new data from the National Cancer Institute. This could offer an alternative treatment option for women with few choices remaining.

NTP Radioisotopes: A glowing example of a South African triumph

NTP Radioisotopes SOC Ltd, a subsidiary of the South African Nuclear Energy Corporation (Necsa), produces a quarter of the world's medical radioisotopes used to allow for about 40 million medical diagnostic images every year, making it the third largest producer and supplier globally. This proud South African corporate citizen is situated at the sophisticated Necsa nuclear facility site, west of Pretoria and routinely serves customers in 60 countries on six continents with its range of nuclear radiation-based products and services.

Advances in genetics and medical imaging meet Richard III

Shakespeare called King Richard III a hunchback, but new genetic and reconstructive CT data show this story had more of a twist. Until recently, the exact nature and whereabouts of Richard's physical deformity was a mystery. While questions still daunt researchers, a compelling picture of the monarch's spine has emerged.

Glass Brain shows 3D detail of brain connectivity

Watch a fly-through of Glass Brain, a 3D imagining of the human brain by researchers at the University of California San Francisco. This video shows the 3D brain model made possible by electroencephalography data and white matter tract reconstruction from MRI diffusion tensor imaging. UCSF is using the technology to research possible treatments for neurodegenerative disease.

Revisiting the human genome

The human genome was first mapped just a little over a decade ago. Its 3 billion bits of DNA are the pages of the human instruction manual. Read this great review featuring Eric S. Lander from MIT, Harvard, and the Broad Institute in Cambridge to see how far we've come and what the future of genomics holds.
