  • Digital Mammography
  • Best Image Quality

DIGITAL MAMMOGRAPHY: Thousand Oaks Radiology is proud to offer Digital Mammography to our patients. Digital Imaging is a more advanced technology and superior to the traditional film method. Film must also be stored and retrieved, which can be a challenge, depending on the number of previous studies and how old the prior exams were.

Thousand Oaks Radiology recognizes the value of digital mammography as part of good patient care. Our Digital Mammography equipment is state-of-the-art.

Routine Mammography screening is recommended annually. Early breast cancer detection dramatically improves outcome.

Using Full-Field Digital Mammography, our Radiologists can easily compare prior/current exams, for more accurate assessments. CAD (Computer Aided Diagnosis) is also used.

No matter which facility you choose for scheduling your appointment, please make sure you ask if the mammography is digital. Thousand Oaks Radiology has offered fully digital mammography since 2002.

  • Osteoporosis
  • Bone Density Evaluation
Osteoporosis is a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased susceptibility to fractures.

Osteoporosis is often called a "silent disease" because bone loss occurs without symptoms. People may not know that they have osteoporosis until their bones become so weak that a minor injury causes a fracture or a vertebral collapse. Collapsed vertebrae may initially be noticed in the form of back pain, loss of height, or spinal deformities such as kyphosis or stooped posture.

Risk Factors: Certain people are more likely to develop osteoporosis than others. Factors that increase the likelihood of developing osteoporosis and fractures are called "risk factors." These risk factors include:

Personal history of fracture after age 50
Current low bone mass
History of fracture in a first degree relative
Being female
Being thin and/or having a small frame
Advanced age
Estrogen deficiency as a result of menopause, especially early or surgically induced
Abnormal absence of menstrual periods (amenorrhea)
Anorexia nervosa
Low lifetime calcium intake
Vitamin D deficiency
Use of certain medications (corticosteroids, chemotherapy, anticonvulsants and others)
Presence of certain chronic medical conditions
Low testosterone levels in men
An inactive lifestyle
Cigarette smoking
Excessive use of alcohol


Women can lose up to 20 percent of their bone mass in the five to seven years following menopause, making them more susceptible to osteoporosis.

How we help: Thousand Oaks Radiology offers bone mineral density (BMD) testing to measure bone density in various sites of the body. A BMD test can:

  1. Detect osteoporosis before a fracture occurs
  2. Predict fracture risk in the future
  3. Determine rate of bone loss and/or monitor the effects of treatment if a DEXA or BMD test is conducted at intervals of one year or more

DEXA is the traditional method to measure bone density. Quantitative CT (also called CT Bone Mineral Density) testing, is offered at both the Conejo MRI/CT and Camarillo-Los Robles Imaging Center. This method has advantages over DEXA, particularly for measuring bone density in the spine.
