OBJECTIVE: The purpose of this article is to review a spectrum of calcified pancreatic masses and propose an algorithm for diagnostic radiologic evaluation. CONCLUSION: Pancreatic calcifications are being detected more frequently because of the widespread use of imaging, particularly CT. Pancreatic calcifications are most commonly associated with chronic pancreatitis related to alcohol abuse. Several other pathologic entities, however, can cause pancreatic calcifications...

OBJECTIVE: The objective of this study is to compare the most recent systems for the staging of multiple myeloma (MM), the Durie-Salmon PLUS system and the International Staging System, according to patients' survival rates and response to therapy. Another objective is to verify whether patterns of bone marrow alteration on MRI (i.e., focal, diffuse, or variegated patterns) can provide prognostic information for patients with MM. MATERIALS AND METHODS: We retrospectively enrolled 85 patients with MM who were monitored for a minimum of 6 years and who underwent contrast-enhanced spinal and pelvic MRI at 1...

OBJECTIVE: The purpose of this study was to analyze the utility of the Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) in the detection of a clinically significant cancers in patients with prostate cancers with a biopsy Gleason score of 6. MATERIALS AND METHODS: A group of 182 consecutively registered patients with biopsy-proven prostate cancer with a Gleason score of 6 underwent MRI and radical prostatectomy. Clinically significant cancer was surgically defined as Gleason score of 7 or greater, tumor volume of 0...

OBJECTIVE: Guidelines for managing thyroid nodules are highly dependent on risk stratification based on sonographic findings. The purpose of this study is to evaluate the risk stratification system used by the American College of Radiology Thyroid Imaging Reporting and Data System (TIRADS). MATERIALS AND METHODS: Patients with thyroid nodules who underwent sonography and fine-needle aspiration were enrolled in a multiinstitutional study. The sonographic nodule features evaluated in the study were composition, echogenicity, margins, and echogenic foci...

OBJECTIVE: Patient perceptions of radiology reports are largely unknown. The objective of the present study is to describe our experience receiving structured feedback from patients on actual radiology reports as a means of improving reporting practices. MATERIALS AND METHODS: Eight reports (two for radiographs, two for ultrasound images, two for CT scans, and two for MR images) were randomly selected from our system for review. For each report, patients were asked to rate their level of comprehension, identify any problems in the report, and, in the free-text portion of the feedback form, indicate any questions about the report that they may have...

OBJECTIVE: In the 29 years since the initial description of Modic type 1 vertebral endplate changes there has been ongoing debate regarding their cause. Studies have attributed Modic type 1 vertebral endplate changes to traumatic injury to the vertebral endplate, localized action of proinflammatory mediators, and more recently low-grade bacterial infection. Can we reconcile these conflicting data about the underlying cause of Modic type 1 vertebral endplate changes? Are we now in a position to conclude whether Modic type 1 vertebral endplate changes are secondary to injury, inflammation, or infection? CONCLUSION: We argue that the processes are not disparate but are in fact closely linked, each potentially instigating a chain of events leading to the MRI findings of Modic type 1 vertebral endplate change...

OBJECTIVE: The aim of this study is to determine whether any correlation between CT findings and functional parameters exists to predict subclinical glucocorticoid secretion. MATERIALS AND METHODS: This is a retrospective database study of 55 patients with incidentally discovered adenomas, investigated through CT with an adrenal protocol, assessing diameters and attenuation values on the unenhanced and contrast-enhanced phases. Patients underwent blood cortisol and corticotropin evaluation and overnight dexamethasone suppression test (DST), in accordance with clinical recommendations...

OBJECTIVE: The objective of this prospective study is to evaluate the consistency of renal stone volume estimation using dual-energy CT across scanner model and reconstruction algorithm configurations. SUBJECTS AND METHODS: Patients underwent scanning with routine kidney stone composition protocols on both second- and third-generation dual-source CT scanners. Images were reconstructed using filtered back projection and iterative reconstruction (IR). In addition, a modified IR kernel on the third-generation CT scanner was evaluated...

OBJECTIVE: We implemented an Image Quality Reporting and Tracking Solution (IQuaRTS), directly linked from the PACS, to improve communication between radiologists and technologists. MATERIALS AND METHODS: IQuaRTS launched in May 2015. We compared MRI issues filed in the period before IQuaRTS implementation (May-September 2014) using a manual system with MRI issues filed in the IQuaRTS period (May-September 2015). The unpaired t test was used for analysis. For assessment of overall results in the IQuaRTS period alone, all issues filed across all modalities were included...

OBJECTIVE: The objective of this article is to summarize the physical principles, technology features, and first clinical applications of optical imaging techniques to the breast. CONCLUSION: Light-breast tissue interaction is expressed as absorption and scattering coefficients, allowing image reconstruction based on endogenous or exogenous contrast. Diffuse optical spectroscopy and imaging, fluorescence molecular tomography, photoacoustic imaging, and multiparametric infrared imaging show potential for clinical application, especially for lesion characterization, estimation of cancer probability, and monitoring the effect of neoadjuvant therapy...

OBJECTIVE: Pediatric small-bowel (SB) Crohn disease (CD) may be missed if the terminal ileum (TI) appears normal at endoscopy and SB imaging is not performed. We sought to estimate the prevalence and clinical characteristics of pediatric patients with CD and endoscopic skipping of the TI-that is, pediatric patients with active SB or upper gut inflammation and an endoscopically normal TI. MATERIALS AND METHODS: This retrospective study included pediatric patients with CD who underwent both CT enterography (CTE) or MR enterography (MRE) and ileocolonoscopy within a 30-day period between July 2004 and April 2014...

OBJECTIVE: The purpose of this article is to discuss whether the sensitivity and specificity of contrast-enhanced digital mammography (CEDM) render it a viable diagnostic alternative to breast MRI. CONCLUSION: That CEDM couples low-energy images (comparable to the diagnostic quality of standard mammography) and subtracted contrast-enhanced mammograms makes it a cost-effective modality for routine screening. CEDM may serve as a realistic substitute for the more costly breast MRI...

OBJECTIVE: Spinal epidural abscess (SEA) is a serious infection requiring prompt treatment and potential neurosurgical intervention. Although contrast-enhanced spine MRI is the mainstay for diagnosis of SEA, unenhanced MRI is typically performed for patients with nonspecific symptoms or insufficient clinical information. We evaluated the sensitivity and specificity of imaging features suggestive of SEA at unenhanced spine MRI. MATERIALS AND METHODS: We searched our database for contrast-enhanced lumbar spine MRI examinations from January 1, 2000, through August 1, 2014, with "epidural abscess" in the report...

OBJECTIVE: Colonoscopy accuracy in detecting colorectal neoplasia is critical for colorectal cancer prevention but has been shown to be operator- and technology-dependent. This article will discuss several recent improvements in the technique and technology of colonoscopy. CONCLUSION: More rigorous training and retraining programs, active monitoring of endoscopist technique and outcomes, and exclusion of poorly performing endoscopists are urgently needed to improve the ultimate efficacy of colorectal cancer screening programs...
