Utility of planning MRI in percutaneous thoracic duct embolization for chylothorax.

Purpose: Percutaneous thoracic duct embolization (TDE) is an accepted treatment for leaks of the central lymphatic ducts. In this study, we correlate the imaging findings on pre-procedural MRI lymphangiography with findings on conventional lymphangiography, and with operator ability to perform a technically successful TDE. The aim was to examine whether MRI is a good screening mechanism to support an invasive procedure in strong candidates, and avert one in poor candidates.

A Simulation Paradigm for Evaluation of Subtle Liver Lesions at Pediatric CT: Performance and Confidence.

Purpose: To create and validate a systematic observer performance platform for evaluation of simulated liver lesions at pediatric CT and to test this paradigm to measure the effect of radiation dose reduction on detection performance and reader confidence.

Materials And Methods: Thirty normal pediatric (from patients aged 0-10 years) contrast material-enhanced, de-identified abdominal CT scans obtained from July 1, 2012, through July 1, 2016, were retrospectively collected from the clinical database. The study was exempt from institutional review board approval.

Hybrid Interactive and Didactic Teaching Format Improves Resident Retention and Attention Compared to Traditional Lectures.

Purpose: To compare the traditional lecture to a hybrid interactive and didactic teaching format with regards to radiology resident short- and long-term retention, as well as attention.

Materials And Methods: The tested hybrid format consists of a 30-minute didactic lecture followed by 30 minutes of interactive cases based on material from the lecture portion. Faculty members were randomly selected to give a 60-minute lecture or a hybrid presentation.

MRI of the Central Lymphatic System: Indications, Imaging Technique, and Pre-Procedural Planning.

Magnetic resonance imaging is increasingly being used to evaluate the lymphatic system. Advances in magnetic resonance (MR) software and hardware allow improved visualization of lymph nodes and lymphatic vessels. We describe how MR lymphangiography can be used to diagnose central lymphatic system anatomy and pathology, which can be used for diagnostic purposes or for pre-procedural planning.

Thoracic duct embolization and disruption for treatment of chylous effusions: experience with 105 patients.

Purpose: To review the indications, technical approach, and clinical outcomes of thoracic duct embolization (TDE) and thoracic duct disruption (TDD) in patients with symptomatic chylous effusions.

Materials And Methods: A total of 105 patients who underwent 120 consecutive TDE/TDD procedures were retrospectively reviewed. Data including cause of effusion, procedural technique, and pre- and postprocedural effusion volume were analyzed.

Safety and utility of transjugular liver biopsy in hematopoietic stem cell transplant recipients.

Purpose: Hematopoietic stem cell transplant (HSCT) recipients are at high risk in the setting of percutaneous liver biopsy as a result of comorbid coagulopathy and ascites, and are commonly referred to undergo transjugular liver biopsy. The present study was performed to assess the safety and utility of transjugular liver biopsy in HSCT recipients and to analyze the correlation between corrected hepatic sinusoidal pressure gradient (CHSPG) and pathologic diagnoses.

Materials And Methods: Data from reports of transjugular liver biopsy procedures, pathology reports, and laboratory values of 141 consecutive HSCT recipients who underwent transjugular liver biopsy with pressure measurement between January 2005 and August 2011 in a single institution were retrospectively reviewed and analyzed.
