Evaluation of a Program for Improving Advanced Imaging Interpretation

The objective of this program evaluation was to compare self-referral rates before and after institution of the imaging interpretation criteria program. Methods The imaging interpretation criteria program allocated privileges to bill for advanced imaging interpretation according to physician specialty. Nonradiologist physicians could obtain exemptions by appeal. Some physicians were not restricted in their billing because of successful appeals of the restrictions or the timing of their contract renewals. Self-referral rates were compared between the period 12 months before and 25 months after the program was initiated using t tests. The preprogram and postprogram self-referral rate for computed tomography and magnetic resonance imaging in aggregate was calculated both for the physicians that came into contact with the program and nationally, and then was stratified based on physician appeal status and reimbursement restrictions. Results The program was associated with significantly less frequent self-referrals by physicians whose appeals were denied (17.4%–8.2%; P = 0.0011) and by physicians notified of the program but not subject to it (24.8%–18.5%; P = 0.026). Self-referrals in the program states declined from 19.9% to 13.7% (P

We report a case of sacral fracture complicated by an intrasacral meningocele in a 37-year-old male. The patient had a left sacral fracture with bilateral fractures of the superior and inferior pubic rami. The sacrum was fixed with a posterior plate and both superior pubic rami were fixed with an intramedullary screw. However, computed tomography myelogram and magnetic resonance imaging showed the intrasacral meningocele with the leakage of the cerebrospinal fluid into the buttocks and developed delayed union. Reoperation utilizing a strong anterior and posterior internal fixation combined with posterior bone grafting was ...

ConclusionsThe use of diagnostic imaging in SUS-Brazil greatly increased since 2002, but was still much lower than in developed countries, mainly for advanced imaging modalities. Nevertheless, the steep growth in CT use in Brazil raises concerns regarding its potential radiation-related risks, mainly among children.

We report a well-documented case of an SFT with malignant histology arising in the inguinal region. CASE PRESENTATION: A 59-year-old man, with an unremarkable medical history, presented with a slow-growing painless mass in the left side of the inguinal region, which he had ignored for 3 years. On clinical examination, there was an indurated, irreducible, mobile, and painless mass in the left side of the inguinal area. Magnetic resonance imaging and computed tomography results revealed a 15-cm mass made up of soft tissue and with nonspecific radiologic aspect. The tumor was totally excised, and the results of the pathol...

AbstractPurpose of ReviewMultimodality imaging is integral for diagnosis, procedural guidance, and follow-up of patients undergoing transcatheter aortic valve replacement (TAVR). In this review, we provide an overview of the role of each imaging modality and highlight technical considerations and pitfalls. We also address current controversies and new developments in the field.Recent FindingsEchocardiography remains the primary imaging modality for diagnosis of aortic stenosis and intraprocedural guidance for TAVR, but computed tomography (CT) imaging has supplanted echocardiography for annular sizing and access site evalu...

In the proposed study, MRI sections were firstly preprocessed to enhance the MR image quality. In the first phase of the preprocessing, MR image intensity normalization, histogram equalization and regional image filling were performed on the input MRI sections. In the second phase...

AbstractPurposeTo determine the consistency of major hepatocellular carcinoma (HCC) features between CT and MRI based on Liver Imaging Reporting and Data System (LI-RADS) v2018 and to investigate the additional value on gadoxetic acid-enhanced MRI.Materials and methodsPatients who underwent dynamic CT and gadoxetic acid-enhanced MRI within 1 month were investigated. Two radiologists evaluated the presence of major HCC features and categorized observations using LI-RADS v2018 algorithm. In addition, each observation was recorded as hyper-, iso-, or hypo-intensity on hepatobiliary-phase (HBP) images.ResultsSixty-one patients...

AbstractChronic silent brain infarctions, detected as new white matter hyperintensities on magnetic resonance imaging (MRI) following transcatheter aortic valve implantation (TAVI), are associated with long-term cognitive deterioration. This is the first study to investigate to which extent the calcification volume of the native aortic valve (AV) measured with cardiac computed tomography angiography (CTA) predicts the increase in chronic white matter hyperintensity volume after TAVI. A total of 36 patients (79  ± 5 years, median EuroSCORE II 1.9%, Q1–Q3 1.5 –3.4%) with severe AV stenos...

Abstract More than 30 million U.S. adults have hearing loss. This condition is underrecognized, and hearing aids and other hearing enhancement technologies are underused. Hearing loss is categorized as conductive, sensorineural, or mixed. Age-related sensorineural hearing loss (i.e., presbycusis) is the most common type in adults. Several approaches can be used to screen for hearing loss, but the benefits of screening are uncertain. Patients may present with self-recognized hearing loss, or family members may observe behaviors (e.g., difficulty understanding conversations, increasing television volume) that sugges...
