Breast tomosynthesis and digital mammography a comparison of diagnostic accuracy

Result Filters

Breast cancer is one of the leading cancers in females worldwide, and its incidence has been rising at an exponential pace in the last 10 years even in India. Mammography has been the mainstay for detection of breast cancer over decades and has gradually advanced from screen film to full-field digital mammography.

Recently, tomosynthesis has evolved as an advanced imaging investigation for early diagnosis of breast lesions in both diagnostic and screening settings. A 1-year prospective longitudinal study was conducted in the Department of Radio-diagnosis in our institute using Hologic Selenia Dimensions for mammography as well as tomosynthesis.

Breast tomosynthesis and digital mammography: a comparison of diagnostic accuracy.

Sensitivity, specificity, positive predictive value, negative predictive value, and P value were used to assess the various diagnostic criteria in our study. Addition of DBT to FFDM results in a statistically significant increase in the sensitivity, specificity, and positive predictive value, and a statistically significant decrease in the false positive rates.

Similar results were noted in both diagnostic and screening cases. It was observed that, in most cases, i. Addition of DBT to FFDM results in increase in sensitivity, specificity, positive predictive value, and a statistically significant decrease in false positive rates in both diagnostic and screening cases.

As addition of tomosynthesis results in a significant decrease in recall rate, it should be added, at least, in all screening mammography programs.

Indian J Radiol Imaging 2018;28: Both the incidence and deaths caused by breast cancer are more than cervical cancer in metropolitan cities.

In India, the average age of developing breast cancer has undergone a significant shift over the last few decades. An increasing number of patients are in the 25—40 years of age, which is a very disturbing trend.

We look for any mass, architectural distortion, or calcification, and then accordingly give BIRADS score Breast imaging reporting and data system. Initially, screen film mammography was done, but at present full-field digital mammography FFDM is gradually replacing film screen mammography.

It has been shown to reduce the rate of death from breast cancer among age group of 40 years of age or older. The resulting data is reconstructed into thin sections through the breast in the orientation of acquisition, e. Several investigations have shown that DBT has potential in both screening and diagnostic settings.

Materials and Methods A 1-year prospective longitudinal study was conducted in the Department of Radio-diagnosis in our institute using Hologic Selenia Dimensions for mammography as well as tomosynthesis.

Novel breast screening technology increases diagnostic accuracy

Pregnant and lactating females and those with open wounds were excluded from the study. The study population was divided into two groups — screening and diagnostic age groups. Screening cases included women above the age of 40 years presenting for breast cancer screening along with women who had already undergone treatment for breast cancer and were on yearly follow-up.

Diagnostic cases included women presenting with breast complaints such as nipple discharge, palpable lump, or pain in breast. Cases were also evaluated on the basis of breast density according to ACR guidelines edition 2013 and age. The images were interpreted at Barco 5. True positives and true negatives were decided on the basis of further diagnostic work-up, which included histopathological examination, other imaging studies such as ultrasonography, magnetic resonance mammography, follow-up, or any one of the above.

  5. Unlike a screening digital mammogram, which involves two X-ray images of each breast, breast tomosynthesis captures multiple, low-dose images from different angles around the breast.

Imaging was done wherever required. Prior approval was taken from the Institutional Review Board. Informed consent was taken from all the patients. Results Out of the total 100 cases, 59 were diagnostic and 41 were screening cases [Table 1]. Maximum cases 49 were in the age group of 41—50 years, among which 21 came for diagnostic imaging and 28 came for screening. Mean age was 49. Proportion of screening and diagnostic cases.
