CT-guided Coaxial Lung Biopsy: Number of Cores and Association with Complications.

Background Percutaneous CT-guided lung core-needle biopsy is a frequently performed and generally safe procedure. However, with advances in the management of lung cancer, there is a need for a greater amount of tissue for tumor genomic profiling and characterization. Purpose To determine whether the number of core samples obtained with percutaneous CT-guided lung biopsy is associated with postprocedural complications.

Thirty-Day Healthcare Encounters after Elective Uterine Artery Embolization for Fibroids with and without Superior Hypogastric Nerve Block.

Purpose: To evaluate how the implementation of superior hypogastric nerve block (SHNB) during uterine artery embolization (UAE) for uterine fibroids impacts same-day discharge and healthcare encounters (HCEs) within 30 days.

Materials And Methods: A total of 240 patients who underwent successful UAE for fibroids between January 2018 and December 2022 were retrospectively reviewed. HCEs within 30 days, including emergency department and urgent care visits, admissions, and readmissions, were categorized as early (0-7 days of discharge) and late (8-30 days of discharge) and related or unrelated to interventional radiology (IR) care.

Incidentally detected pancreatic duct dilatation on ultrasound and role of MRI.

Objective: The clinical significance of incidentally detected pancreatic duct (PD) dilatation at ultrasound (US) without a visualized underlying cause is unclear. We aimed to assess the role of subsequent MRI (including MRCP) and to identify US imaging and laboratory findings predictive of underlying pancreaticobiliary malignancy at the time of initial US.

Materials And Methods: Patients with incidentally detected PD dilatation at ultrasound from 2011 to 2019 that had an ensuing MRI were included.

Sterile gown and drape, and bouffant cap for thyroid FNA: preventing infections or producing unnecessary medical waste?

Purpose: Ultrasound-guided fine needle aspiration (FNA) is a very low-risk procedure. Despite this, there remains great variability in the use of protective equipment. Given the monetary and environmental costs of protective equipment, the difference in infection rates with full versus limited protective equipment was assessed.

The Role of Imaging for Gastrointestinal Bleeding: Consensus Recommendations From the American College of Gastroenterology and Society of Abdominal Radiology.

Gastrointestinal (GI) bleeding is the most common GI diagnosis leading to hospitalization within the United States. Prompt diagnosis and treatment of GI bleeding is critical to improving patient outcomes and reducing high healthcare utilization and costs. Radiologic techniques including computed tomography angiography, catheter angiography, computed tomography enterography, magnetic resonance enterography, nuclear medicine red blood cell scan, and technetium-99m pertechnetate scintigraphy (Meckel scan) are frequently used to evaluate patients with GI bleeding and are complementary to GI endoscopy.

ACR Appropriateness Criteria® Clinically Suspected Adnexal Mass, No Acute Symptoms: 2023 Update.

Asymptomatic adnexal masses are commonly encountered in daily radiology practice. Although the vast majority of these masses are benign, a small subset have a risk of malignancy, which require gynecologic oncology referral for best treatment outcomes. Ultrasound, using a combination of both transabdominal, transvaginal, and duplex Doppler technique can accurately characterize the majority of these lesions.

ACR Appropriateness Criteria® Acute Pelvic Pain in the Reproductive Age Group: 2023 Update.

This review focuses on the initial imaging in the reproductive age adult population with acute pelvic pain, including patients with positive and negative beta-human chorionic gonadotropin (β-hCG) levels with suspected gynecological and nongynecological etiology. For all patients, a combination of transabdominal and transvaginal pelvic ultrasound with Doppler is usually appropriate as an initial imaging study. If nongynecological etiology in patients with negative β-hCG is suspected, then CT of the abdomen and pelvis with or without contrast is also usually appropriate.

Highest 3-month international normalized ratio (INR): a predictor of bleeding following ultrasound-guided liver biopsy.

Objectives: To determine whether international normalized ratio (INR), bilirubin, and creatinine predict bleeding risk following percutaneous liver biopsy.

Methods: A total of 870 consecutive patients (age 53 ± 14 years; 53% (459/870) male) undergoing non-targeted, ultrasound-guided, percutaneous liver biopsy at a single tertiary center from 01/2016 to 12/2019 were retrospectively reviewed. Results were analyzed using descriptive statistics and logistic regression models to evaluate the relationship between individual and combined laboratory values, and post-biopsy bleeding risk.

A Multicenter Study of Needle Size and Safety for Splenic Biopsy.

Background Splenic biopsy is rarely performed because of the perceived risk of hemorrhagic complications. Purpose To evaluate the safety of large bore (≥18 gauge) image-guided splenic biopsy. Materials and Methods This retrospective study included consecutive adult patients who underwent US- or CT-guided splenic biopsy between March 2001 and March 2022 at eight academic institutions in the United States.

Peer learning in abdominal radiology: iterative process improvements over a 20-year experience.

Purpose: After a slow and challenging transition period, peer learning and improvement (PLI) is now being more widely adopted by practices as an option for continuous personal and practice performance improvement. In addition to gaps that exist in the understanding of what PLI is and how it should be practiced, wide variation exists in how the process is implemented, administered, how outcomes are measured, and what strategies are employed to engage radiologists. This report aims to describe lessons learned from our 20-year experience with the design, implementation, and continuous improvements of a PLI program in a large academic program.

Routine radiology-pathology concordance evaluation of CT-guided percutaneous lung biopsies increases the number of cancers identified.

Background: Routine concordance evaluation between pathology and imaging findings was introduced for CT-guided biopsies.

Purpose: To analyze malignancy rate in concordant, discordant, and indeterminate non-malignant results of CT-guided lung biopsies.

Methods: Concordance between pathology results and imaging findings of consecutive patients undergoing CT-guided lung biopsy between 7/1/2016 and 9/30/2021 was assessed during routine meetings by procedural radiologists.

Safety profile and technical success of narrow window CT-guided percutaneous biopsy with blunt needle approach in the abdomen and pelvis.

Objective: To assess success and safety of CT-guided procedures with narrow window access for biopsy.

Methods: Three hundred ninety-six consecutive patients undergoing abdominal or pelvic CT-guided biopsy or fiducial placement between 01/2015 and 12/2018 were included (183 women, mean age 63 ± 14 years). Procedures were classified into "wide window" (width of the needle path between structures > 15 mm) and "narrow window" (≤ 15 mm) based on intraprocedural images.

Challenges, Barriers, and Successes of Standardized Report Templates: Results of a Society of Interventional Radiology Survey.

Registry data are being increasingly used to establish treatment guidelines, set benchmarks, allocate resources, and make payment decisions. Although many registries rely on manual data entry, the Society of Interventional Radiology (SIR) is using automated data extraction for its VIRTEX registry. This process relies on participants using consistent terminology with highly structured data in physician-developed standardized reports (SR).
