Biliary abnormalities in children are uncommon, and the spectrum of biliary disorders is broader than in adult patients. Unlike in adults, biliary disorders in children are rarely neoplastic and are more commonly rhabdomyosarcoma rather than cholangiocarcinoma. Pediatric biliary disorders may be embryologic or congenital, such as anatomic gallbladder anomalies, anomalous pancreaticobiliary tracts, various cholestatic processes, congenital cystic lesions, or genetic conditions.

While benign, these lesions have historically undergone surgical excision due to their potential to be upgraded to malignancy. However, there is emerging evidence that a tailored management approach should be considered to reduce overtreatment of these lesions.

Knowledge of the clinical presentation and imaging features of the various stages of normal development and mass-forming lesions in the pediatric breast can guide a tailored imaging approach and help the radiologist make a definitive diagnosis. Breast development begins during fetal gestation along the embryologic milk lines and continues through puberty as the breast matures through the Tanner stages of development.

Objective: To assess the efficacy of magnetic resonance imaging (MRI)-directed ultrasound (US) in further characterizing lesions detected on MRI and to evaluate the correlation between lesion characteristics and their visibility on US.
Methods: A retrospective review was performed of the records of patients with breast abnormalities detected on MRI between May 2018 and December 2020. All patients who were given a Breast Imaging-Reported and Data System Assessment Category 4 or 5 on breast MRI and sent to breast US for assessment of the MRI abnormality were included.
Knowledge of normal testicular F-FDG PET/CT (FDG PET/CT) SUVs is crucial for accurate examination interpretation. The objective of this study was to establish normal testicular SUV ranges among adult men receiving health care in North America. A retrospective review of an institutional electronic database identified adult men undergoing pretreatment clinical FDG PET/CT examinations from March 15, 2013, through March 15, 2018.

At our institution, sodium bicarbonate (the buffer) is dispensed in volumes that frequently lead to medical waste and shortages. In this study, we describe how moving the buffering of lidocaine from the procedure room to our clinical hospital pharmacy results in a reduction in costs and improves satisfaction across the breast radiology department.

Methods: All cases of isolated solitary dilated ducts between January 1, 2009 and December 31, 2016 in non-lactating females were reviewed. Clinical data, including patient's age, breast cancer history, and pathology results were collected.
New techniques have reduced the radiation dose delivered from a computed tomography (CT) examination. These techniques do not affect the number of scans ordered, the number of phases in each examination, or the scan length, as these parameters are controlled by ordering providers and CT technologists. The purpose of this study was to determine if deploying low-dose CT resulted in an increase in radiation exposure because of more liberal ordering habits or more liberal scanning ranges.

Conclusion: Tomosynthesis-guided needle localizations were performed for 38 lesions, including 14 architectural distortions, five groups of calcifications, two focal asymmetries, three masses, four breast clips, and 10 axillary clips. All lesions were successfully removed at surgery, indicating that breast and axillary lesions can be precisely localized under tomosynthesis.
Background: There is no accurate method distinguishing different types of pulmonary nodules.
Purpose: To investigate whether multiparametric 3T MRI biomarkers can distinguish malignant from benign pulmonary nodules, differentiate different types of neoplasms, and compare MRI-derived measurements with values from commonly used noninvasive imaging modalities.
Study Type: Prospective.
