Impact of pelvic CT on staging, surveillance, and survival of pediatric patients with Wilms tumor and hepatoblastoma.
Abdominopelvic CT is often performed in children with Wilms tumor or hepatoblastoma. However, the reported incidence of recurrent disease involving the pelvis is low. This study explores the impact of abdominopelvic CT on children with Wilms tumor or hepatoblastoma. ⋯ In our study population, abdominopelvic CT did not detect pelvic metastases to affect subsequent treatment. Given the low rate of pelvic involvement at relapse in children with Wilms tumor and hepatoblastoma, frequent abdominopelvic CT may not be necessary. Replacing these examinations with abdomen-only CT should be considered to decrease radiation burden to this population.

Intraarterial recombinant tissue plasminogen activator thrombolysis of acute and semiacute lower limb arterial occlusion: quality assurance, complication management, and 12-month follow-up reinterventions.
The purpose of this study is to assess the efficacy of intraarterial thrombolysis in acute and semiacute occlusions of the lower limb. ⋯ Intraarterial rt-PA thrombolysis is an effective and reasonable method for treating acute peripheral arterial occlusion. The method is less effective in semiacute occlusions, leading to extended hospitalization. Within 12 months, a quarter of the patients required reinterventions, and amputations were necessary in 10% of the cases.

Performing true whole-body FDG PET/CT is standard practice in pediatric lymphoma staging and follow-up. In adults, imaging is typically limited whole-body PET/CT, which has advantages over true whole-body PET/CT, primarily decreased scanning time and decreased radiation. We hypothesize that in pediatric lymphoma, limited whole-body PET/CT is sufficient for routine follow-up when disease on the true whole-body staging study is confined to the limited whole-body field of view (FOV). ⋯ The limited whole-body PET/CT for routine follow-up when disease is confined to the limited whole-body FOV at staging is appropriate. Given its definite advantages over true whole-body PET/CT, it is preferred.

Comparative StudyPreoperative MDCT evaluation of congenital lung anomalies in children: comparison of axial, multiplanar, and 3D images.
The objective of our study was to compare the preoperative diagnostic accuracy of axial, multiplanar, and 3D MDCT images for evaluating congenital lung anomalies in pediatric patients and to assess the potential added diagnostic value of multiplanar and 3D MDCT images in this setting. ⋯ Axial MDCT images allow accurate diagnosis of the types, location, associated mass effect, and anomalous arteries of congenital lung anomalies, but supplemental multiplanar and 3D MDCT images add diagnostic value for the evaluation of congenital lung lesions associated with anomalous veins.

Analysis and prioritization of near-miss adverse events in a radiology department.
The purpose of this study is to describe a method for the evaluation and prioritization of near-miss events in a radiology department. ⋯ This method was constructed from standardized definitions of outcome severity, the ability of current systems to detect or mitigate an adverse event or outcome, and event frequency and offers a tool for systematic evaluation and stratification of near-miss adverse events.
