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.

Sentinel lymph node mapping for ovarian cancer?

With all of the recent expansion of sentinel lymph node mapping for melanoma and breast cancers and now in all solid tumors, some experts are wondering about the value of this technique for ovarian cancer. A study published ahead of print Oct. 20 in the Journal of Nuclear Medicine makes the case.

Endomicroscopic imaging points to esophageal disease prior to surgery

Surgery for gastroesophageal reflux disease (GERD) could be improved by an emerging imaging technique called endomicroscopy, which can detect cellular changes indicating pre-cancerous or cancerous growths. The system can also be used to monitor patients for recurrent disease after GERD anti-reflux surgery.

Lilly to pay reduced punitive damages in bladder cancer trial

Eli Lilly and Company, makers of amyloid PET agent Amyvid, announced yesterday evening that the judge in the case of Terrence Allen, et al. v. Takeda Pharmaceuticals North America, Inc., et al, has ruled to reduce punitive damages for defendants Takeda and Lilly from $6 billion and $3 billion, respectively, down to $27.6 million and $9.2 million.

Hyperpolarized lung MRI portrays the perils of smoking

A relatively new MR technique that vastly improves imaging resolution is able to find the minute lung pathology associated with smoking habits—even before respiratory symptoms become a drag, according to a study published ahead of print Oct. 13 in Radiology.
