Positron Emission Tomography (PET) in Cardiology
Positron emission tomography (PET) imaging is useful in assessment of myocardial perfusion and viability, atherosclerotic plaque activity as well as cardiac innervation in heart failure. PET is also useful in prosthetic valve endocarditis, endocarditis associated with cardiac implantable electronic devices (CIED), infiltrative cardiomyopathy, aortic stenosis and cardio oncology [1].
PET imaging has superior diagnostic accuracy compared to SPECT (Single Photon Emission Computed Tomography). It has improved spatial and temporal resolution and can measure regional blood flow and has less radiation. In PET, high energy gamma...

Using MRI and PET to Detect Early Knee Osteoarthritis
Researchers from Stanford University have developed the first protocol using magnetic resonance imaging (MRI) for detecting early stage knee osteoarthritis (OA) in all joint tissues. Their findingswere recently published inOsteoarthritis and Cartilage. Traditionally, joint tissues are examined separately, and MRI can only assist in monitoring changes in the subchondral bone when the disease has progressed substantially. The group of researchers led by Feliks Kogan, PhD, saw the need to create a technique that could non-invasively assess changes in bone remodeling and adjacent tissues.The researchers studied patients wi...

18F-Sodium Fluoride PET Imaging of Osseous Metastatic Disease
Article in AJR by Curtis G Mick et al,review details the history, pharmacokinetics, and utility of 18F-sodium fluoride (Na18F) PET/CT in detecting osseous metastases compared with the current standard of care, technetium-99m methylene diphosphonate (99mTc-MDP) bone scintigraphy. They concluded that Na18F PET/CT is the most comprehensive imaging modality for the evaluation of osseous metastatic diseaseRead More: http://www.ajronline.org/doi/abs/10.2214/AJR.13.12158From Sumer's Radiology Site http://www.sumerdoc.blogspot.com -The Top Radiology Magazine.

The Beauty Brains respond:
The important question isn’t how it works, it’s why in the heck they’d name a toothpaste flavor after an antiperspirant! Oh well, it’s nice when the scent of your breath matches the smell of your armpits. But we digress…
How does toothpaste for sensitive teeth work?
