Guiding Imaging Tests
We all know someone – a family member, friend, or neighbor – who has had some form of medical imaging. Whether it’s an X-ray mammogram, CT lung scan or MRI with contrast of the knee, our health care system uses an increasing number of imaging tests to help identify a variety of diseases and injuries.
For the most part, advances in imaging are a very good thing. Especially when they are used to get the best imaging information with the lowest possible radiation dose.
Medical imaging saves lives and makes it easier for radiologists such as Kenneth Salce, M.D., of Northern Arizona Radiology, to find and diagnose disease as soon as possible and with the most accuracy.
"Advances in medical imaging over the past 20 years have been amazing,” said Salce. “Greater accuracy and lower radiation have continued to make imaging procedures better, safer and faster, saving lives and helping to rule out – or more effectively treat – injury and disease."
Lung Cancer Awareness
National Lung Cancer Awareness month is November, and it’s also the perfect time to see how far we’ve come in the fight against the number one cancer killer of men and women.
The good news is that according to American Cancer Society (ACS) data, more than 430,000 people alive today have been diagnosed with lung cancer at some point, and National Cancer Institute (NCI) reports show that lung cancer rates overall are down nationally and in Arizona. NCI trends show that the overall mortality (death) rate for lung cancer (lung and bronchus) rose steadily through the 1980s, peaked in the early 1990s, and has been slowly declining since 2001. In Arizona, according to the NCI, the annual lung cancer mortality rate is 38.5 deaths per 100,000, a decline of 2.7 percent over the five-year period from 2008 to 2012. The number of newly diagnosed cases in Arizona (lung cancer incidence) has remained stable over the same five-year period.
DEXA and Bone Density
We don’t often think of bones as tissue, but our bones are actually a type of connective tissue, the most common tissue in the human body. Cartilage, bone marrow and blood are also types of connective tissue. In addition to making blood cells (red blood cells, white blood cells and platelets) our bones are so important because they basically hold us together, protect vital organs and allow us to move efficiently.
As with any other human structure, bones can develop problems that may seriously impact our health. The most common bone diseases is osteoporosis, a condition that happens when we lose too much bone, don’t make enough bone, or a combination of both.
