Integrity of clinical information in computerized order requisitions for diagnostic imaging.
This study compared the integrity of electronic health record (EHR) imaging order requisitions with EHR provider notes and their potential impact on order inaccuracies and interpretation of results. This retrospective study was conducted at a tertiary academic medical center using MRI lumbar spine and CT abdomen/pelvis orders performed from April 1 to May 31, 2016. Results showed that requisition indications were more likely to be incomplete than provider notes. Researchers recommended that relevant documentation be more readily available in EHRs.

Assessing information sources to elucidate diagnostic process errors in radiologic imaging - a human factors framework.
The purpose of this study was to assess information sources that may elucidate errors related to radiologic diagnostic imaging, quantify the incidence of potential safety events from each source, and quantify the number of steps involved from diagnostic imaging chain and socio-technical factors. Information sources can elucidate errors in various steps within the diagnostic imaging workflow and can provide insight into socio-technical factors that impact patient safety in the diagnostic process.

Automated pulmonary embolism risk classification and guideline adherence for computed tomography pulmonary angiography ordering.
The objective of this study was to measure the performance of automated, structured data-only versions of the Wells and revised Geneva risk scores in emergency department encounters during which a computed tomography pulmonary angiography was ordered. The hypothesis was that such an automated method would classify a patient's pulmonary embolism risk with high accuracy compared to manual chart review.

Qualitative study to understand ordering of CT angiography to diagnose pulmonary embolism in the emergency room setting.
The purpose of the study was to better understand, using semi-structured interviews, the decision making behind the ordering of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) in the emergency department. The authors found that EM providers were the main drivers of CTPA ordering, and there was a marginalized role for the radiologist. Experience- and gestalt-based heuristics were the main influencers of CTPA ordering.

Performance characteristics of digital vs film screen mammography in community practice.
In this study, the investigators examined performance characteristics of digital vs film screen mammography in community practice by comparing the performance characteristics of 297 629 full field digital (FFDM) and 416 791 screen film mammograms (SFM). In their study, modest gains in performance were achieved with the introduction of FFDM as a replacement for SFM, in a large health care organization.

Diagnosing stroke in acute dizziness and vertigo: pitfalls and pearls.
Diagnosing cerebrovascular causes of acute dizziness and vertigo is both important and difficult. It is not routinely done well in current clinical ED practice. Current best evidence suggests an approach emphasizing dizziness timing and triggers, focused ocular motor examinations, and MRI, as needed. Alternative strategies to disseminate this approach may be required.

An adaptive motion regularization technique to support sliding motion in deformable image registration.
To accurately model and estimate sliding tissue motion, an adaptive direction-dependent DVF regularization technique was developed in this study to model the sliding tissue motion of the thoracic and abdominal organs. The overall motion estimation accuracy was improved especially near the chest wall and abdominal wall where large organ sliding motion occurs.

Electronic triggers to identify delays in follow-up of mammography: harnessing the power of big data in health care.
Because of the unique clinical, logistic, and legal aspects of mammography, this study was conducted to evaluate the effectiveness of a trigger to flag delayed follow-up on mammography. The investigators found that care delays appeared to continue despite federal laws requiring patient notification of mammographic results within 30 days. They suggest that clinical application of mammography-related triggers could help detect these delays.

Diagnostic and prognostic value of myocardial blood flow quantification as non-invasive indicator of cardiac allograft vasculopathy.
Cardiac allograft vasculopathy (CAV) is a leading cause of death in orthotopic heart transplant (OHT) survivors. Effective non-invasive screening methods are needed. The aim of this study was to investigate the added diagnostic and prognostic value of myocardial blood flow (MBF) to standard myocardial perfusion imaging (MPI) with positron emission tomography (PET) for CAV detection.
