A perspective on medical infrared imaging

“…There are clear indications that thermography is a valid (Ammer and Ring, 2008;Zaproudina et al, 2006) technology, which is both non-invasive and low-cost, that rapidly produces a non-contact recording of the energy irradiated from the body (Han et al, 2010;George et al, 2008;Jiang et al, 2005). It has been recently shown that a high resolution thermal image can provide interesting information about the complex thermoregulation system of the body (Pascoe el al., 2008).…”

Thermal body patterns for healthy Brazilian adults (male and female), Journal of Thermal Biology, http://dx.doi.org/10. 1016/j.jtherbio.2014.02.020 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript.

A B S T R A C TThe aim of this study was to establish the skin temperature (T sk ) thermal profile for the Brazilian population and to compare the differences between female and male Brazilian adults. A total of 117 female and 103 male were examined with a thermographic camera. The T sk of 24 body regions of interest (ROI) were recorded and analyzed. Male T sk results were compared to female and 10 ROI were evaluated with respect to the opposite side of the body (right vs. left) to identify the existence of significant contralateral T sk differences (ΔT sk ). When compared right to left, the largest contralateral ΔT sk was 0.3 °C. The female vs. male analysis yielded significant differences (p <0.05) in 13 of the 24 ROI. Thigh regions, both ventral and dorsal, had the highest ΔT sk by sex (≈ 1.0 °C). T sk percentile below P 5 or P 10 and over P 9o or P 95 may be used to characterize hypothermia and hyperthermia states, respectively. Thermal patterns and T sk tables 2 were established for Brazilian adult men and women for each ROI. There is a low T sk variation between sides of the body and gender differences were only significant for some ROIs. Keywords: Infrared thermographySkin temperature Thermal symmetry Brazilian profile HighlightsEstablishing a standard thermographic profile is crucial for an appropriate interpretation.Standardization of the protocols leads to obtain comparable results.Gender seems to be a determining factor for the skin temperature of the thigh, calf and dorsal arm.We suggest the value of 0.5 °C as a normal limit for contralateral ΔT sk.

“…These conditions are commonly associated with regional vasodilation, hyperthermia, hyperperfusion, hypermetabolism, and hypervascularization (27)(28)(29), which generate a highertemperature heat source. Unlike imaging techniques such as X-ray, ultrasonography, MRI, and other structural imaging tools that primarily provide information on the anatomical structures, infrared imaging provides functional information that is not easily measured by other methods.…”

Comparison of standard mammography with digital mammography and digital infrared thermal imaging for breast cancer screening Breast cancer is the most common malignancy in women. Screenfilm mammography (SFM) has been considered the gold standard for breast cancer screening and detection. Despite its recognized value in detecting and characterizing breast disease, mammography has important limitations and its false-negative rate ranges from 4% to 34%. Given these limitations, development of imaging modalities that would enhance, complement, or replace mammography has been a priority. Digital mammography (FFDM) and digital infrared thermal imaging (DITI) are some of these alternative modalities.

Abstract ÖzetReview 152 IntroductionBreast cancer is the most common malignancy and the second most common cause of cancer death in women in the US (1). According to the American Cancer Society report on cancer facts, it accounts for about 30% of all cancers in women. Approximately one in every eight women is diagnosed with breast cancer by the age of 90, with an absolute lifetime risk of 14.4% (2). In Turkey, the ratio of breast cancer is 24.1%, ranking first of all the cancers in women (3). The incidence of breast cancer has increased, and the estimated number of breast cancer cases was 44,253 in 2007 (4, 5). There is a geographical heterogeneity regarding breast cancer incidence and survival rates in Turkey. The incidence in Western Turkey (50/100,000 in 2000) is more than twice that of the Eastern part (20/100,000) (5-7). Five year survival rates for breast cancer are 85% in Western and 60% in Eastern Turkey (7). Breast cancer survival depends upon its earliest possible detection because survival rate increases with earlier detection with a possibility of complete cure. Breast cancer has a ten year survival rate for Stage 0of 95%; Stage I, 88%; Stage II, 66%; Stage III, 36%; and stage IV, 7% (8). Larger tumor size at diagnosis is also associated with decreased survival (9). Screening might produce greater benefits for early detection if it were more sensitive and specific. A wide variety of new technologies, including alternative imaging modalities, and improvements in x-ray mammography, are being investigated with the aim of improving early-detection rates. Many imaging modalities can be used for breast screening, such as X-ray; ultrasonography, magnetic resonance imaging (MRI); computed tomography (CT); ultrasound; positron emission tomography (PET) scan...
