SU-E-I-110: Minimized Pediatric Dose in Direct Radiography (DR).

Medical physics

So J, Nickoloff E, Dutta A, Jambawalikar S.
PMID: 28517622
Med Phys. 2012 Jun;39(6):3650. doi: 10.1118/1.4734827.

PURPOSE: Pediatric x-rays techniques are not standardized. They depend upon: patient size, anatomical localized and equipment manufacturers. Most pediatric techniques use the default factory settings. This project's goal is to find the best compromise between dose to pediatric patients...

Accuracy of Distinguishing Atypical Ductal Hyperplasia From Ductal Carcinoma In Situ With Convolutional Neural Network-Based Machine Learning Approach Using Mammographic Image Data.

AJR. American journal of roentgenology

Ha R, Mutasa S, Sant EPV, Karcich J, Chin C, Liu MZ, Jambawalikar S.
PMID: 30860901
AJR Am J Roentgenol. 2019 Mar 12;1-6. doi: 10.2214/AJR.18.20250. Epub 2019 Mar 12.

OBJECTIVE: The purpose of this study was to test the hypothesis that convolutional neural networks can be used to predict which patients with pure atypical ductal hyperplasia (ADH) may be safely monitored rather than undergo surgery.MATERIALS AND METHODS: A...
