Repeated CT Scans Linked to Breast Cancer: Study
December 4th, 2012 | Posted by in MRI Vancouver - (0 Comments)Not only is MRI technology the most effective form of diagnostic imaging, it is also the
safest. Imaging solutions like X-rays are paradoxical; on one hand, they are able to address and diagnose immediate health concerns, but on the other hand they threaten future health by exposing the body to harmful radiation.
A new Chicago study has determined that CT scans can increase the risk of breast cancer in females–especially in the case of younger women and women who have had repeated exposure to nuclear medicine imaging. CT scans involve injecting a tiny amount of radioactive material into the patient in order to get a clear picture of the body’s internal organs through the scanner, and breast tissue is one of the most cancer-sensitive areas of the body in terms of absorbing radiation.
The researchers looked at 1,656 patients who had CT scans in which the breast was exposed to radiation. Each patient’s radiation does was estimated by an automated method, as was the amount of radiation absorbed by the breast.
“We found that the estimated breast radiation doses from CT were highly variable across patients, with with highest doses coming from multiple-phase cardiac and chest CT examinations, where successive images of the organ being studied are captured,” said Dr. Rebecca Smith-Bindman, senior author of the study.
Adding to that, co-author Diana Miglioretti stated: “Young women receiving several chest and or cardiac CTs had the greatest increased risk of developing breast cancer at approximately 20 per cent. A 15-year-old girl with no risk factors for breast cancer would double her 10-year risk of developing breast cancer at 25.”


If you’re a first-time patient of Aim Medical Imaging, you can anticipate a clean, hospitable and professional environment, but if you’ve never had an MRI scan before it’s difficult to know exactly what to expect. To help with that, we’ve recently updated our
but our state-of-the-art scanner features a 70 cm Open Bore, allowing 30 cm of space above the face.
Immediate Results – The Aim Difference
45 college students had their brains scanned for the study; each one answered 20 questions (presented in written and video formats) associated with socializing and empathizing, and 20 questions involving physics problems. Researchers found that during the physics-based, or analytical problems the analytical parts of the brain were engaged while the parts associated with socializing remained dormant. While answering the questions associated with social skills and empathy, the opposite occurred. These findings are just the beginning of a new frontier in mental health, and could have many advantageous benefits for people coping with anxiety, depression and other social/mental health issues.
