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 warns against using thermography for cancer screening, calls out California center

“There is no valid scientific data to show that thermographic devices, when used on their own or with another diagnostic test, are an effective screening tool for any medical condition, including the early detection of breast cancer or other diseases and conditions,” the FDA wrote. “The agency stresses that mammography is the only screening method proven to reduce deaths from breast cancer through early detection.”

CTA, transcranial Doppler not accurate in screening for delayed ischemia following brain hemorrhage

CT angiography (CTA) and transcranial Doppler (TCD) fall short in detecting cerebral vasospasm (CVS) and predicting delayed cerebral ischemia (DCI) in patients with subarachnoid hemorrhage (SAH), reported authors of a recent study published in the inaugural edition of Critical Care Explorations.

Cardiac MRI-derived T2 mapping may help heart failure patients

Researchers used T2 mapping taken from weekly cardiac MRIs to help identify cardiotoxicity at an early stage, according to results of a pig study published Feb. 18 in the Journal of the American College of Cardiology. The findings could help cancer patients at risk of chemo-induced heart failure.

T2 mapping may uncover cardiotoxic marker early enough to prevent heart failure

T2 mapping derived from weekly cardiac MRIs helped researchers identify cardiotoxicity at an early and reversible stage, a finding which may have implications for cancer patients at risk of chemotherapy-induced heart failure.

Department of Energy seeks agreement to produce Mo-99 domestically

The Department of Energy’s National Nuclear Security Administration (NNSA) has chosen four U.S. companies to begin negotiations with in an effort to produce Molybdenum-99 (Mo-99) without the use of highly enriched uranium.

Novel PET/CT tracer safe, effective for diagnosing acute venous thromboembolism

A novel PET/CT imaging agent—18F-GP1—produced a high-quality image and yielded a high detection rate for diagnosing acute venous thromboembolism (VTE), reported researchers of a study featured in the February issue of The Journal of Nuclear Medicine.

SABR improves survival for early, inoperable lung cancer patients

Stereotactic ablative body radiation therapy (SABR) nearly doubled the overall survival of patients with inoperable stage I lung cancer compared to standard radiotherapy, according to results of a multi-center phase III trial published in the Lancet Oncology.

fMRI reveals nerve stimulation could ease emotional, physical pain in PTSD patients

The FDA has approved nerve stimulation for treatment of episodic and chronic cluster headaches and acute migraines. The findings, detailed in a study published online Feb. 13 in PLOS ONE, could help personalize treatment for PTSD, which according to the National Institute of Mental Health impacts roughly 3.6 percent of U.S. adults per year. 

Around the web

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
