Comparison of standard mammography with digital mammography and digital infrared thermal imaging for breast cancer screening

Abstract

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...

Best practices for standardized performance testing of infrared thermographs intended for fever screening

“…IR thermography-also known as thermal imaging-is a non-contact and noninvasive imaging approach that has been exploited for a wide range of biomedical and non-biomedical applications. It has been studied for use in cancer imaging [1][2][3][4][5][6][7], ischemic monitoring and vascular disease [8,9], wound assessment [10], corneal temperature measurement [11][12][13], diagnosis of rheumatologic diseases [14], fever screening [15][16][17][18][19][20][21][22][23][24][25][26] been encountered in clinical translation of IR thermography. Standardization in different aspects of medical thermography, including tools (both acquisition hardware and processing algorithm) and examination environment, has always been a general agreement among the community of medical thermography [27].…”

Medical applications of infrared thermography: A review

“…Several applications of IRT in medical science has been highlighted by Jung et al [24] and Ammer and Ring [25]. IRT has been extensively used for diabetic neuropathy [16,[26][27][28][29][30][31], vascular disorder [6,32,33], breast cancer detection [34][35][36][37][38][39][40], thermoregulation study [4,5], fever screening [41][42][43][44], brain imaging (thermoencephaloscopy) [45], dentistry and dermatology [46][47][48], muscular pain and shoulder impingement syndrome study [49], diagnosis of rheumatologic diseases [50][51][52], dry eye syndrome diagnosis [53], treatment of parasitic liver diseases [54], detection of metastatic liver disease [55], bowel ischemia [56], renal transplantation [57,58], heart treatment [59], and gynecology [60][61][62]. IRT has been used in acupuncture treatment [63][64]…”

The influence of size, depth and histologic characteristics of invasive ductal breast carcinoma on thermographic properties of the breast

“…At present, there are still mixed opinions on the usefulness of thermography as a screening or diagnostic tool for breast cancer, with certain authors in favor of the modality (Köşüş et al, 2010[21]), while others argue against it (Vreugdenburg et al, 2013[38]). This is mostly due to the inconsistent specificity and sensitivity values observed by various authors.…”
