TL;DR: CTTA, in conjunction with random forest modeling, demonstrates promise as a tool to characterize lesions and various renal masses were accurately classified using quantitative information derived from routine scans.

TL;DR: In this paper, the authors discuss contemporary applications of 2-deoxy-2-[18F]fluoro-Dglucose (FDG)-PET and FDG-PET/CT as well as novel developments in quantification and potential future indications including the emerging new modality PET/magnetic resonance imaging.

TL;DR: Distractions in the form of telephone call interruptions may negatively impact on-call radiology resident diagnostic accuracy and efforts should be made to limit distractions in the reading room.

TL;DR: The top cited articles in radiologic journals span a wide range of imaging modalities, subspecialties, and organ systems and highlights the importance of including classic articles in current imaging education.

TL;DR: 60-keV monoenergetic image data significantly improve vessel attenuation and CNR of cervical and cerebral DECT angiographic studies and future studies have to evaluate whether the technique can lead to an increased diagnostic accuracy or should be used for dose reduction of iodinated contrast material.

TL;DR: Both Marshall andRotterdam scoring systems can be used to predict early death in patients with TBI and the performance of the Marshall score is at least equal to that of the Rotterdam score.

TL;DR: Corrected linear-binning provides a robust means to quantify ventilation images yielding VDP values that are indistinguishable from expert reader scores, while exploiting the entire dynamic range to depict multiple image clusters.

TL;DR: FDG-PET and PET/CT seem to be useful in staging, evaluating disease activity, and monitoring treatment response in patients with sarcoidosis, and PET appears to have higher diagnostic accuracy compared to Gallium-67-citrate scintigraphy.

TL;DR: This EPR dosimetry system is capable of measuring radiation-induced free radicals in the tooth of irradiated human subjects to determine the exposure dose and offers potential opportunities for clinical dosimetric and oximetry, which include guiding therapy for individual patients with tumors or vascular disease by monitoring of tissue oxygenation.

TL;DR: The sensitivity of previously published vessel criteria for identifying PH patients is high, but the specificity may not be high enough for routine use in a clinical patient population.

TL;DR: Insight is offered into what factors make programs appealing to radiology applicants and this information will be useful to medical educators engaged in career counseling and recruitment.

TL;DR: The results demonstrate the feasibility of the instrument for noninvasive mapping of optical, physiological, and ultrasound contrasts in human skin tumors for surgery guidance and therapy planning.

TL;DR: MEI at 70 keV had the highest IQob with equal liver CNR and metastasis-to-liver ratio compared to PEI, and IRs might improve their diagnostic confidence in the assessment of hepatic GIST metastases by evaluating MEI reconstructions at 70keV.

TL;DR: The displacement magnitude of the median nerve was found to be less in patients with CTS compared to healthy subjects during most movements, with the exception of wrist extension with fingers extended.

TL;DR: The IMR can provide improved image quality at super-low-dose cardiac CT with 20% of the standard tube current with no significant difference in the CT attenuation among the three reconstructions.

TL;DR: In this article, the authors investigated residents' knowledge of adverse effects of ionizing radiation, frequency of their education on radiation safety, and their use of radioprotective equipment.

TL;DR: PD-related changes were found in putative iron content over 2 years and the rate of changes was associated with individual characters, such as cognitive decline and age.

TL;DR: The ability to perform noninvasive measurements of cerebrovascular parameters has far-reaching clinical implications, and the diagnosis and assessment of neurovascular disorders, traumatic brain injury, and stroke would benefit from measurements of local cerebral hemodynamics and autoregulation.

TL;DR: DWI may not help to alter posttest probability compared to pretest probability to sufficiently alter physician's decision making, and with respect to the accuracy and DOR, DWI is useful for differentiation between malignant and benign pulmonary nodules or masses.

TL;DR: MBIR imaging shows higher overall quality with lower noise and streak artifacts than ASIR or FBP imaging, resulting in nearly 80% dose reduction without any degradations of overall image quality.

TL;DR: In this paper, the authors investigated the value of DW, perfusion-sensitive (IVIM), and dynamic contrast-enhanced (DCE)magnetic resonance imaging (MRI) technologies in assessing the response of bone metastases frombreastcancertoradiotherapy.

TL;DR: Mesoscopic fluorescence molecular tomography, by imaging fluorescence signals over large areas with high spatial sampling and at fast acquisition speeds, may be a new imaging modality of choice for planning and optimizing of PDT treatment.

TL;DR: It is demonstrated that any legislative action and respective news coverage correlate with increase in information seeking for "dense breast" on Google, suggesting that Google Trends has the potential to serve as a data source for policy-relevant research.

TL;DR: Four-dimensional PC MR imaging allows for accurate assessment of QP:QS ratios in the evaluation of intracardiac shunts while absolute flow volumes demonstrate offsets.

TL;DR: RS- EPI DWI images showed improved image quality compared to SS-EPI technique at 3T, indicating that RS-EPi is a feasible technique in the pelvis for producing high-resolution DWI.

TL;DR: F-FDG-PET and PET/CT demonstrated to be accurate diagnostic imaging methods in the differential diagnosis between malignant and benign pleural lesions; nevertheless, possible sources of false-negative and false-positive results should be kept in mind.

TL;DR: IMR reduces intravascular noise on cCTA by 86%-88% compared to FBP, and improves image quality at radiation exposure levels 80% below the authors' standard technique.

TL;DR: The preliminary study demonstrated that the early biochemical changes in knee osteoarthritic patients could be detected noninvasively in in vivo using T₁ρ and dGEMRIC-T⁁ mapping.

TL;DR: Although the number of patients is relatively small with heterogeneous state of disease, MRS in PCC may serve as a useful noninvasive tool for diagnostic of patients with cognitive impairment and pain.

TL;DR: CESM is accurate in size measurements of small breast tumors, whereas US tends to underestimate tumor size and CESM seems to be helpful in the characterization of breast tissue around microcalcifications.
