Digital Mammography in Breast Cancer: Additive Value of Radiomics of Breast Parenchyma.

Radiology 2019 Feb 12:181113. Epub 2019 Feb 12.

From the Department of Radiology, University of Chicago, 5841 S Maryland Ave, Chicago, IL 60637.

Background Previous studies have suggested that breast parenchymal texture features may reflect the biologic risk factors associated with breast cancer development. Therefore, combining the characteristics of normal parenchyma from the contralateral breast with radiomic features of breast tumors may improve the accuracy of digital mammography in the diagnosis of breast cancer. Purpose To determine whether the addition of radiomic analysis of contralateral breast parenchyma to the characterization of breast lesions with digital mammography improves lesion classification over that with radiomic tumor features alone.

Purpose To determine the increase in clinically significant cancer detection in the prostate with increasing number of core samples obtained by using cognitive MRI-targeted transrectal US biopsy. Materials and Methods This retrospective cross-sectional study included 330 consecutive patients (mean age, 64.3 years; range, 42-84 years) who underwent multiparametric prostate MRI from March 2012 to July 2017 and had an index lesion that subsequently underwent cognitive MRI-targeted biopsy using transrectal US with at least five core samples (which were sequentially labeled) per lesion.

Purpose To investigate metabolic changes in chronic spinal cord injury (SCI) by applying MR spectroscopy in the cervical spinal cord. Materials and Methods Single-voxel short-echo spectroscopic data in study participants with chronic SCI and healthy control subjects were prospectively acquired in the cervical spinal cord at C2 above the level of injury between March 2016 and January 2017 and were compared between groups. Concentrations of total N-acetylaspartate (tNAA), myo-inositol (mI), total choline-containing compounds (tCho), creatine, and glutamine and glutamate complex were estimated from the acquired spectra.

Potential Effect of the Protecting Access to Medicare Act on Use of Advanced Diagnostic Imaging in the Emergency Department: An Analysis of the National Hospital Ambulatory Care Survey.

Radiology 2019 Jan 29:181650. Epub 2019 Jan 29.

From the Department of Emergency Medicine (J.F., H.K.K., R.C.W.), Center for Healthcare Value (J.F.), Philip R. Lee Institute for Health Policy Studies (H.K.K.), and Department of Radiology and Biomedical Imaging (J.M.), University of California, San Francisco, 505 Parnassus Ave, L126, San Francisco, CA 94143-0209; Division of General Internal Medicine and Health Services Research, David Geffen School of Medicine, University of California, Los Angeles, Los Angeles, Calif (K.L.K.); and RAND Corporation, Santa Monica, Calif (K.L.K.).

Background Clinical decision support is increasingly used to enhance clinicians' exposure to established evidence and patient information during an episode of patient care. Pending legislation specifies clinical decision support before performing advanced imaging at emergency department (ED) visits. Purpose To estimate the volume of advanced imaging tests (CT and MRI) that would require use of clinical decision support to achieve Protecting Access to Medicare Act (PAMA) compliance in the ED.

Validation of A Method to Compensate Multicenter Effects Affecting CT Radiomics.

Radiology 2019 Jan 29:182023. Epub 2019 Jan 29.

From the UCA, Inria Sophia Antipolis-Méditerranée, Epione, 2004 route des Lucioles-BP 93, 06 902 Sophia Antipolis Cedex, France (F.O., N.A.); and Imagerie Moléculaire In Vivo, CEA-SHFJ, Inserm, CNRS, Université Paris-Sud, Université Paris-Saclay, Orsay, France (F.F., C.N., I.B.).

Background Radiomics extracts features from medical images more precisely and more accurately than visual assessment. However, radiomics features are affected by CT scanner parameters such as reconstruction kernel or section thickness, thus obscuring underlying biologically important texture features. Purpose To investigate whether a compensation method could correct for the variations of radiomic feature values caused by using different CT protocols. Read More

Deep learning has rapidly advanced in various fields within the past few years and has recently gained particular attention in the radiology community. This article provides an introduction to deep learning technology and presents the stages that are entailed in the design process of deep learning radiology research. In addition, the article details the results of a survey of the application of deep learning-specifically, the application of convolutional neural networks-to radiologic imaging that was focused on the following five major system organs: chest, breast, brain, musculoskeletal system, and abdomen and pelvis.

Purpose To evaluate readability of websites that are commonly accessed for information on breast lesions requiring surgery. Materials and Methods An internet search using three malignant and eight nonmalignant breast lesions that traditionally require lumpectomy or excisional biopsy as search terms was conducted to identify websites commonly accessed for patient information on breast lesions requiring surgery. Nine websites with information on breast diagnoses were identified based on search engine results for each breast lesion queried. Read More

Case 266.

Radiology 2019 Feb;290(2):566-568

From the Departments of Radiology (C.J.C., C.M.) and Otorhinolaryngology (L.F.), University Hospital Crosshouse, Kilmarnock, Scotland.

History A 1-year-old boy was referred for cochlear implant assessment after he received a diagnosis of bilateral profound sensorineural hearing loss at neonatal hearing screening shortly after birth. The child was born at term via uneventful delivery, and there was no history of familial hearing loss or maternal illness. Tympanic membranes were normal, and hearing loss was confirmed with auditory brainstem testing, which showed no response from either ear. Read More
