Straightforward imaging with an infrared, thermal, camera for
detecting breast cancer early without the discomfort or inconvenience of mammography
or biomolecular tests.
Tiago Borchartt of the Federal Fluminense University in Brazil and
colleagues explain how breast thermography has up to now achieved an average
sensitivity and specificity or approximately 90 percent for the detection of
malignant tissue. The advantages of the technique are that it is painless,
requires no contact between patient and instrumentation and is entirely
non-invasive. However, a 90 percent accuracy rate implies that there is a lot
of room for improvement before such a technique could become a mainstream
clinical diagnostic for the early stages of breast cancer.
The team has developed new software that allows them to acquire
thermal images into a computer database and so be used to help with diagnosis
after the automatic extraction of the regions of interest. The same tool
combines storage with feature extraction and recognition. The approach can
detect the presence of problems using symmetric analysis and numerical simulations
using finite element analyses allows it to analyze the relationships between
internal temperature and the temperature on the breast surface during image
acquisition.
So far, the researchers have tested their approach on a limited
number of thermal images from 28 patients: four healthy patients, eight with
cysts, eleven patients with fibroadenoma and five with carcinoma. They were
able to improve the accuracy of breast thermography using their approach to
96%. The next step will be to test this in larger group of at least 2000
patients. That future project has already been approved by the ethical
committee of the University Hospital of UFF.
