A cost-effective handheld breast scanner for use in low-resource environments: a validation study

چکیده
BACKGROUND With the incidence of breast cancer rising worldwide, we are evaluating the iBreastExam (iBE) (UE LifeSciences Inc.), a handheld breast scanning device that can be utilized by community health workers to screen for breast abnormalities. The purpose of this study is to determine the sensitivity of the iBE in a population undergoing diagnostic breast imaging. METHODS Adult patients presenting to a breast imaging center for a diagnostic workup were eligible. Patients underwent an iBE exam performed by a trained ultrasound technician followed by their indicated imaging. Demographic, imaging, and biopsy data were recorded. RESULTS Seventy-eight iBE exams were completed, 77 females and one male with a mean age of 42 (21-79). All patients were evaluated by ultrasound, 52 had diagnostic mammography and 39 had biopsies. Imaging and/or biopsy confirmed a mass (fibroadenoma, cyst, papilloma, myofibroblastoma, fat necrosis, DCIS, or cancer) in 60 patients. Twelve patients had a cancer diagnosed. In total, 342 quadrants were scanned, 77 quadrants had lesions confirmed on imaging, and iBE correctly identified 66 lesions for a sensitivity of 86 % and specificity of 89 %. CONCLUSIONS This validation study demonstrated excellent sensitivity of iBE for the identification of clinically significant lesions in patients presenting for diagnostic imaging.

متن کاملThe Continued Utility and Viability of Dakin’s Solution in Both High- and Low-resource Settings
Healthcare is expensive and often inaccessible to many. As a result, surgeons must consider simple, less expensiveinterventions when possible. For wound care, an older but quite effective cleaning agent is Dakin’s solution (0.5%sodium hypochlorite), an easily made mixture of 100 milliliters (ml) bleach with 8 teaspoons (tsp) baking soda into agallon of clean water or 25 ml ble...
متن کاملMeasurements agreement between low-cost and high-level handheld 3D scanners to scan the knee for designing a 3D printed knee brace
Use of additive manufacturing is growing rapidly in the orthotics field. This technology allows orthotics to be designed directly on digital scans of limbs. However, little information is available about scanners and 3D scans. The aim of this study is to look at the agreement between manual measurements, high-level and low-cost handheld 3D scanners. We took two manual measurements and three 3D ...
متن کاملQuantification of Estrogen Receptor-Alpha Expression in Human Breast Carcinomas With a Miniaturized, Low-Cost Digital Microscope: A Comparison with a High-End Whole Slide-Scanner
INTRODUCTION A significant barrier to medical diagnostics in low-resource environments is the lack of medical care and equipment. Here we present a low-cost, cloud-connected digital microscope for applications at the point-of-care. We evaluate the performance of the device in the digital assessment of estrogen receptor-alpha (ER) expression in breast cancer samples. Studies suggest computer-ass...
