Effect of Ultra-High Resolution CT on Pseudoenhancement in Renal Cysts: A Phantom Experiment and Clinical Study.

AJR Am J Roentgenol 2022 May 18. Epub 2022 May 18.

Department of Radiology, National Defense Medical College, Namiki 3-2, Tokorozawa, Saitama, Japan.

Ultra-high resolution CT (U-HRCT) allows acquisition using a small detector element size, in turn allowing very high spatial resolutions. The high resolution may reduce partial-volume averaging and thereby renal cyst pseudoenhancement. To assess the impact of U-HRCT on renal cyst pseudoenhancement. Read More

Time for Resolution of COVID-19 Vaccine-Related Lymphadenopathy and Associated Factors.

AJR Am J Roentgenol 2022 May 18. Epub 2022 May 18.

Weill Cornell Medicine, Department of Radiology, 525 East 68th Street, New York, NY 10065.

The variable clinical course of subclinical lymphadenopathy detected on breast imaging after COVID-19 vaccination creates management challenges and has led to evolving practice recommendations. To assess the duration of axillary lymphadenopathy ipsilateral to COVID-19 vaccination detected by breast imaging and to assess factors associated with the time until resolution. This retrospective single-center study included 111 patients (mean, 52±12 years) with unilateral axillary lymphadenopathy ipsilateral to Pfizer or Moderna COVID-19 vaccine administration performed within the prior 8 weeks that was detected on breast ultrasound performed between January 1st, 2021, and October 1st, 2021 and that underwent follow-up ultrasound examinations at 4-12 week intervals until resolution of the lymphadenopathy.

Intravascular Ultrasound Guidance for Transjugular Intrahepatic Portosystemic Shunt Procedures: A Review.

AJR Am J Roentgenol 2022 May 18. Epub 2022 May 18.

Dotter Department of Interventional Radiology, Oregon Health and Science University, 3181 SW Sam Jackson Park Rd, Portland, Oregon, USA.

The most challenging and time-consuming step of transjugular intrahepatic portosystemic shunt (TIPS) procedures is obtaining appropriate portal vein access. Given the lack of real-time direct target visualization, conventional fluoroscopic guidance requires multiple passes, contributing to complications. In comparison, intravascular ultrasound (IVUS) guidance during TIPS procedures provides direct visualization of hepatic structures and real-time guidance for portal vein puncture. Read More

Practice Management Strategies for Imaging Facilities Facing an Acute Iodinated Contrast Media Shortage.

AJR Am J Roentgenol 2022 May 13. Epub 2022 May 13.

Department of Radiology and Biomedical Imaging, Yale School of Medicine.

An unanticipated but severe shortage in iodinated contrast media (ICM) is currently affecting imaging practices across the globe and is expected to persist through at least the end of June 2022. This supply shock may lead to healthcare systems experiencing an acute imaging crisis, as many affected facilities have contrast agent supplies that are anticipated to last only a week or two under normal operating conditions. To maximize the opportunity to continue to provide optimal care for patients with emergent or life-threatening imaging indications and thereby minimize the overall impact on patient care, practice leaders will need to quickly assess their contrast material inventories, prioritize examination indications, and reduce their expected short-term usage of ICM.

Artificial Intelligence (AI) for Lung Nodules: From the Special Series on AI Applications.

AJR Am J Roentgenol 2022 May 11. Epub 2022 May 11.

Interest in artificial intelligence (AI) applications for lung nodules continues to grow among radiologists, particularly with the expanding eligibility criteria and clinical utilization of lung cancer screening (LCS) CT. AI has been heavily investigated for detecting and characterizing lung nodules, as well as for guiding prognostic assessment. AI tools have also been used for image postprocessing (e. Read More

Liver Transplant for Non-Hepatocellular Malignancies: A Review for Radiologists.

AJR Am J Roentgenol 2022 May 11. Epub 2022 May 11.

Weill Cornell Medical College, Department of Radiology.

Although traditionally only performed for hepatocellular carcinoma (HCC), the last decade has seen a resurgence in the use of liver transplant (LT) for non-HCC malignancies, likely due to improvements in neoadjuvant treatment regimens as well as the establishment of well-defined eligibility criteria. Given promising survival results, patients with perihilar cholangiocarcinoma, neuroendocrine liver metastases, and hepatic hemangioendothelioma are eligible to receive Model for End Stage Liver Disease (MELD) exception for tumors that meet well-defined criteria. Additional tumors such as colorectal cancer liver metastases, intrahepatic cholangiocarcinoma, and hepatocholangiocarcinoma may undergo transplant at specialized centers with well-defined protocols, although are not yet eligible for MELD exception.

Imaging Surveillance Options for Individuals With a Personal History of Breast Cancer: Expert Panel Narrative Review.

AJR Am J Roentgenol 2022 May 11. Epub 2022 May 11.

Department of Radiology, University of Washington School of Medicine and Seattle Cancer Care Alliance, 825 Eastlake Ave E, LG-200, Seattle, WA 98040.

Annual surveillance mammography is recommended for breast cancer survivors based on observational studies and meta-analyses showing reduced breast cancer mortality and improved quality of life. However, breast cancer survivors are at higher risk of subsequent breast cancer and have a 4-fold increased risk of interval breast cancers compared to individuals without a personal history of breast cancer. Supplemental surveillance modalities offer increased cancer detection compared to mammography alone, but utilization is variable, and benefits must be balanced with possible harms of false-positive findings.

Department of Radiology, Emory University and Children's Healthcare of Atlanta, 1405 Clifton Rd., Atlanta, GA 30322.

Pediatric hepatocellular carcinoma (HCC) is an aggressive malignancy for which imaging findings remain poorly described. In comparison with adult HCC, pediatric HCC more commonly occurs without underlying risk factors, and standardized surveillance guidelines for those with predispositions are lacking. To evaluate imaging findings of non-fibrolamellar pediatric HCC and to identify associations between these imaging findings and presence of predisposing factors. Read More

Prostate MRI Qualification: Expert Panel Narrative Review.

AJR Am J Roentgenol 2022 May 11. Epub 2022 May 11.

Section of Abdominal Imaging, Imaging Institute, Glickman Urological and Kidney Institute, Cleveland Clinic, Cleveland, OH, USA.

Prostate MRI is now established as a first-line investigation for individuals presenting with suspected localized or locally advanced prostate cancer. Successful delivery of the MRI-directed pathway for prostate cancer diagnosis relies on high-quality imaging as well as the interpreting radiologist's experience and expertise. Radiologist certification in prostate MRI may help limit inter-reader variability, optimize outcomes, and provide individual radiologists with documentation of meeting predefined standards.
