Hematomas can be managed conservatively, but aspiration can lead to decreased pain, decrease in heterotopic ossification, and earlier return to sports activities. The purpose of this study is to evaluate the safety and efficacy of ultrasound-guided aspiration of intramuscular hematomas, and to evaluate the associations between the sonographic appearance of hematomas and their age and ease of aspiration An IRB waiver-approved, retrospective search of our radiology database was conducted between 1/01/2008 - 9/28/2017. Associations between ease of aspiration with echotexture, age of the hematoma, hematoma location, and needle gauge were accessed with a marginal proportional logistic regression model estimated using generalized estimating equations (GEE), accounting for patients with multiple hematomas.

The purpose of this study was to compare clinical and chest CT findings in patients with influenza A (H1N1) pneumonia and coronavirus disease (COVID-19) pneumonia. Thirty patients with diagnosed influenza A (H1N1) virus infection (group A) and 30 patients with diagnosed COVID-19 (group B) were retrospectively enrolled in the present study. The clinical characteristics and chest CT findings of the two groups were compared. Read More

Nonmass Enhancement Breast Lesions: Diagnostic Performance of Kinetic Assessment on Ultrafast and Standard Dynamic Contrast-Enhanced MRI in Comparison With Morphologic Evaluation.

AJR Am J Roentgenol 2020 May 26:1-8. Epub 2020 May 26.

Department of Radiology, University of Chicago, Chicago, IL.

The purpose of this article was to evaluate the diagnostic performance of the kinetic parameters of ultrafast and standard dynamic contrast-enhanced MRI (DCE-MRI) compared with morphologic evaluation in differentiating benign from malignant nonmass enhancement (NME) breast lesions. A total of 77 consecutive patients with 77 NMEs (23 benign and 54 malignant) underwent 3-T MRI, including one unenhanced and eight contrast-enhanced ultrafast DCE-MRI scans (7-second scans) and standard DCE-MRI scans. The two readers evaluated the lesions' likelihood of malignancy on a continuous scale from 0 to 100% as the morphologic score using standard DCE-MRI. Read More

Percutaneous Minimally Invasive Thermal Ablation of Osseous Metastases: Evidence-Based Practice Guidelines.

AJR Am J Roentgenol 2020 May 26:1-9. Epub 2020 May 26.

Mallinckrodt Institute of Radiology, St. Louis, MO.

The objective of this article is to describe evidence-based guidelines for percutaneous minimally invasive imaging-guided thermal ablation of bone metastases. Safe and effective minimally invasive thermal ablation can be performed to achieve pain palliation, local tumor control, or cure in selected subgroups of patients with osseous metastases. Thermal protection strategies should be implemented to minimize the risk of undesired thermal injury. Read More

Utilization Trends in Abdominal Imaging, 2004-2016.

AJR Am J Roentgenol 2020 May 26:1-5. Epub 2020 May 26.

Department of Radiology, Center for Research on Utilization of Imaging Services, Thomas Jefferson University Hospital, 132 S 10th St, Ste 780-A Main, Philadelphia, PA 19107.

The purpose of this study was to analyze recent trends in abdominal imaging utilization in the Medicare population. Medicare Part B databases for 2004-2016 were reviewed, and all Current Procedural Terminology codes pertaining to noninvasive imaging of the abdomen and pelvis were identified. Codes were grouped into six categories: CT and CT angiography (CTA), MRI and MR angiography (MRA), ultrasound, radionuclide imaging, radiography, and gastrointestinal fluoroscopy. Read More

CT Features of Coronavirus Disease (COVID-19) in 30 Pediatric Patients.

AJR Am J Roentgenol 2020 May 22:1-9. Epub 2020 May 22.

Department of Radiology, Massachusetts General Hospital, Boston, MA.

The purpose of this study is to characterize the CT findings of 30 children from mainland China who had laboratory-confirmed coronavirus disease (COVID-19). Although recent American College of Radiology recommendations assert that CT should not be used as a screening or diagnostic tool for patients with suspected COVID-19, radiologists should be familiar with the imaging appearance of this disease to identify its presence in patients undergoing CT for other reasons. We retrospectively reviewed the CT findings and clinical symptoms of 30 pediatric patients with laboratory-confirmed COVID-19 who were seen at six centers in China from January 23, 2020, to February 8, 2020.

Reorganizing Cross-Sectional Interventional Procedures Practice During the Coronavirus Disease (COVID-19) Pandemic.

AJR Am J Roentgenol 2020 May 22:1-5. Epub 2020 May 22.

Department of Radiology, Beth Israel Deaconess Medical Center, Boston, MA.

The purpose of this article is to present strategies and guidelines that can be implemented in the performance of cross-sectional interventional procedures during the coronavirus disease (COVID-19) pandemic. Radiologists who perform cross-sectional interventional procedures can take several steps to minimize the risks to patients and radiology personnel, including screening referred patients to decide which procedures can be postponed, using appropriate personal protective equipment (PPE), minimizing the number of people involved in procedures, preserving PPE when possible, and applying proper room and equipment cleaning measures.
