Bone density testing for osteoporosis

Osteoporosis is a condition that causes very weak and brittle bones. If you have osteoporosis, a minor fall or even a deep cough could be enough to cause a bone break or fracture. The primary screening test for osteoporosis is referred to as a "dual-energy x-ray absorptiometry" (DEXA) test. This painless, noninvasive method of measuring your bone mass can detect osteoporosis before a fracture occurs. It can also estimate your risk of having a fracture in the future.

Although osteoporosis is preventable, it cannot be cured. Treatment focuses on reducing the occurrence of fractures and slowing bone loss. Specifically, the treatment and management of osteoporosis involves lifestyle changes and medicine. An orthopedic surgeon may also recommend surgery.

Endoscopy services

An endoscopy is a procedure that allows physicians to better examine the body's passageways, including the esophagus, stomach and colon. With an endoscope, your doctor can directly look at specific areas to better evaluate and detect problems. He or she can also use the endoscope to remove tissue for a biopsy.

Colonoscopy

The most common type of endoscope is a colonoscopy. During a colonoscopy, a doctor inserts an endoscope into the patient’s rectum. This allows the physician to detect colon polyps, inflammation, tumors or other irritants inside the large intestine. If abnormal growths are found, tissue samples can be collected for further testing or can be removed altogether.

A colonoscopy is vital to the early detection of colon cancer. Colon cancer is often called the "silent killer" because patients typically do not start experiencing symptoms until the cancer is advanced. Primary care doctors suggest most men and women 50 years old and older have a colonoscopy at least once every five years.

Endoscopic ultrasound (EUS)

EUS obtains high-quality images and information from a patient's digestive tract. By combining endoscopy and ultrasound technology, EUS provides clearer, more detailed images of the patient's esophagus, stomach or pancreas. Physicians use EUS in cancer diagnosis and treatment to determine depths of tumor penetration and identify the spread of cancer. An EUS may also be used to assess chronic pancreatitis, evaluate causes of abdominal pain and analyze tumors.

Other advanced endoscopic procedures

In addition to routine endoscopy procedures, we also perform more advanced procedures, including:

  • Stent placements
  • Fine needle aspiration (FNA)
  • Percutaneous endoscopic gastrostomy (PEG) placement
  • Manometry with impedance
