Rationale and Objectives Gliomatous tumors are known to affect neural fiber integrity, either by displacement or destruction. The aim of this study is to investigate the integrity and distribution of the white matter tracts within and around the glioma regions using probabilistic fiber tracking. Material and Methods Forty-two glioma patients were subjected to MRI using a standard tumor protocol with diffusion tensor imaging (DTI). The tumor and peritumor regions were delineated using snake model...

Rationale and Objectives This study aims to evaluate the diagnostic accuracy, inter-reader, and intra-reader variability of the ACR Thyroid Imaging Reporting and Data System (TI-RADS) for risk-stratification of indeterminate thyroid nodules using next generation genetic sequencing and tissue histology as a reference standard. Materials and Methods Retrospective chart review was performed on all patients who underwent thyroid ultrasound for a nodule with subsequent fine-needle aspiration ± surgic...

Background Transcatheter aortic valve replacement (TAVR) procedural success relies heavily on volumetric reconstruction imaging, particularly ECG-gated multi-detector row computed tomography. We postulated that single examination using fast low-angle shot (FLASH) dual source CT scanning (DS-CTA) could provide lower dose than ECG-gated CTA while maintaining the image quality. Methods In this single-centre cohort study, all patients who underwent ECG-gated and FLASH DS-CTA were evaluated. Volumetr...

Rationale and Objectives Accurate preoperative identification of lateral cervical lymph node metastasis (LNM) is important for decision-making and clinical management of patients with papillary thyroid carcinoma (PTC). The aim of this study was to develop an ultrasound (US)-based radiomic nomogram to preoperatively predict the lateral LNM in PTC patients. Methods In this retrospective study, a total of 886 patients were enrolled and randomly divided into 2 groups. Radiomic features were extracte...

Rationale and Objectives To identify the outcomes of stereotactic vacuum-assisted large bore biopsies performed on sonographically-occult non-calcified mammographic lesions (NCL). Materials and Methods In an IRB-approved retrospective study, we reviewed all NCL that underwent stereotactic biopsy from January 1, 2014 to December 31, 2017 at our institution, comparing patient age, lesion type, size and location with pathology outcome (benign, high-risk or malignant) using Wilcoxon-Mann-Whitney or ...

Rationale and Objectives Periventricular and deep white matter hyperintensities (WMHs) in the elderly have been reported with distinctive roles in the progression of cognitive decline and dementia. However, the definition of these two subregions of WMHs is arbitrary and varies across studies. Here, we evaluate three partition methods for WMH subregions, including two widely used conventional methods (CV & D10) and one novel method based on bilateral distance (BD). Materials and Methods The three...

Cybersecurity is increasingly affecting the healthcare sector. In a recent article, the authors analyzed specific attacks against picture archiving and communications systems (PACS) and medical imaging networks and proposed security measures. This article discusses issues that require consideration when deploying these proposed measures and provides recommendations on how to implement them. Hospitals should deploy virus scanners on systems where permitted, with high priority on devices that are ...

Rationale and Objectives Online educational modules can augment radiology learning by creating opportunities to interact with images in more dynamic ways than with static presentation of images in lectures or journal articles. Building these modules on an online survey platform allows for quantitative assessment and learner feedback, without requiring programming knowledge or need for new website creation. Materials and Methods Interactive online tutorials were built on a web-based survey platfo...

Rationale and Objectives The purpose of this study was to investigate the potential of photon-counting CT (PCCT) to improve quantitative image quality for low dose imaging compared to energy-integrating detector CT (EID CT). Materials and Methods An investigational scanner (Siemens, Germany) with PCCT and EID CT subsystems was used to compare image quality performance at four dose levels: 1.7, 2, 4, 6 mGy CTDIvol, all at or below current dose values used for conventional abdominal CT. A CT quali...
