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.
