Diagnostic
Outpatient imaging places it's focus at prevention and early
detection. Molecular imaging allows physicians to go even further,
detecting disease at the cellular level, before any symptoms or
signs are noticeable. CT scans can detect lung cancer at its initial
and most treatable stage. A New England Journal of Medicine study
says CT screening could eliminate 80% of lung cancer deaths in high
risk patients. Molecular imaging holds the promise of identifying
disease at the earliest possible time, even before symptoms are
apparent. Ultrasound scans can detect dangerous abdominal aneurysms
before they burst—and the scans are cost-effective. Imaging
identifies stroke rapidly, aiding physicians in fast treatment that
can save lives and reduce disabilities. Digital Mammography
identifies breast cancer one to three years before a lump can be
felt, thereby saving lives. Early detection reduces the risk of
death in women 50 to 69 years of age by 30 percent; in women in
their 40s, the risk can drop by 17 percent. The Lancet reports that
earlier diagnosis through mammography is a factor in the dramatic
improvement in the 15-year survival rate during the 1990s among
breast cancer patients in the US and Europe. Virtual colonoscopy
using 3-D imaging identifies colorectal cancer when it is still
highly treatable – and it's faster and more comfortable than
traditional exams.

MRI and Cancer - An MRI is
a diagnostic image technology used pinpoint cancer cells (and other
abnormal cells) within your body. Studies have shown that an MRI is
remarkably sensitive in finding some cancers that other diagnostic
tools may simply miss. An MRI helps to locate those hard to
find and possibly hidden cancers and is particularly useful in
diagnosing and staging of cancer. When the stage of cancer is
correctly identified, a physician is better able to recommend the
treatment plan that is likely to be the most effective in treating
the cancer.

Guided Biopsy vs. Exploratory Surgery - Image Guided
Biopsies are minimally invasive procedures
that are guided by fluoroscopy, CT, ultrasound and MRI imaging have
virtually replaced exploratory surgery of the chest, breast,
abdomen, pelvis, and bone as the standard in medical diagnostics.
These image-based procedures are anywhere from three to seven times
more cost-effective, are less risky and require less recovery time
than exploratory surgery (open surgical biopsies). A 2002 study in
Radiology found that image-guided percutaneous biopsy of bone tumors
is safe and accurate, but also that it represents important savings
and efficiencies for patients and employers. Among them:
shorter procedure time, fewer infections, easier wound healing, and
earlier start for treatment when cancer is found. "With a definitive
diagnosis,… therapy can be started the day after core-needle biopsy.
After a surgical approach, a delay of 10 days to 3 weeks is required
to allow wound healing and prevention of infection and bleeding."
Digital
Mammography -
Breast cancer is one of the most easily treated forms of
cancer if caught early enough.
Studies show that when detected early, the chance for
successful treatment of breast cancer is nearly 100%.
Death from breast
cancer is preventable, especially when detected early.
Studies have shown that Digital Imaging can increase early
detection by up to 30% over analog imaging or screen film
imaging. Widespread use of mammography
to detect lumps and even pre-cancerous cellular changes is
regarded as one of the most successful innovations in modern
public health. An important study called DMIST (Digital Mammographic Imaging
Screening Trial), sponsored by the National Cancer Institute
and published online by the New England Journal of Medicine
showed that 65% of women would benefit from the use of digital
mammography over the tradition film screen mammography (see
DMIST). These women are;
- under age 50 (regardless of level of
breast tissue density)
- of any age, with heterogeneously
(very dense) or extremely dense breast tissue.
- or pre or perimenopausal women of any
age (defined as women who had a last menstrual period within
12 months of their mammograms).
