CT imaging of clinically significant abdominopelvic injuries in the damage control surgery patient.

Purpose: Damage Control Surgery (DCS) refers to a staged laparotomy performed in patients who have suffered severe blunt or penetrating abdominopelvic trauma with the goal of managing critical injuries while avoiding life threatening metabolic derangements. Within 24 h of the initial laparotomy, computed tomography (CT) is used to assess the full extent of injuries. The purpose of this study was to assess the incidence of clinically significant unknown abdominopelvic injuries which required further dedicated surgical or interventional radiology management and failed surgical repairs identified on CT following initial laparotomy.

Pre-Cut Papillotomy Versus Endoscopic Ultrasound-Rendezvous for Difficult Biliary Cannulation: A Systematic Review and Meta-Analysis.

Background: Various endoscopic techniques are employed to achieve biliary cannulation when confronted with difficult biliary access. Every procedure carries its own risk in terms of bleeding, infection, pancreatitis, and cholangitis. Our meta-analysis aimed to compare pre-cut papillotomy and endoscopic ultrasound (EUS)-rendezvous in terms of technical success rates, and post-procedure pancreatitis and bleeding.

BC-QNet: A quantum-infused ELM model for breast cancer diagnosis.

The timely and accurate diagnosis of breast cancer is pivotal for effective treatment, but current automated mammography classification methods have their constraints. In this study, we introduce an innovative hybrid model that marries the power of the Extreme Learning Machine (ELM) with FuNet transfer learning, harnessing the potential of the MIAS dataset. This novel approach leverages an Enhanced Quantum-Genetic Binary Grey Wolf Optimizer (Q-GBGWO) within the ELM framework, elevating its performance.

Artificial intelligence improves resident detection of pediatric and young adult upper extremity fractures.

Purpose: We wished to evaluate if an open-source artificial intelligence (AI) algorithm ( https://www.childfx.com ) could improve performance of (1) subspecialized musculoskeletal radiologists, (2) radiology residents, and (3) pediatric residents in detecting pediatric and young adult upper extremity fractures.

Utility of Zero-Echo time sequence as an adjunct for MR evaluation of degenerative disease in the cervical spine.

Objective: Determine the utility of ZTE as an adjunct to routine MR for assessing degenerative disease in the cervical spine.

Methods: Retrospective study on 42 patients with cervical MR performed with ZTE from 1/1/2022 to 4/30/22. Fellowship trained radiologists evaluated each cervical disc level for neural foraminal (NF) narrowing, canal stenosis (CS), facet arthritis (FA), and presence of ossification of the posterior longitudinal ligament (OPLL).

Imaging of the Ankle Ligaments and Cartilage Injuries as an Aid to Ankle Preservation Surgery.

Ankle sprains are among the most common musculoskeletal injuries and can lead to ankle ligament and cartilage injuries. Imaging plays an important role in differentiating ligament injuries from other causes of ankle pain such as fractures, osteochondral lesions or tendon injuries that helps guide further management. Chronic untreated ankle ligamentous and cartilage injuries can further progress to ankle osteoarthritis, hence the need for timely diagnosis and treatment.

Bones and Soft-Tissue Tumors: Considerations for Postsurgical Imaging Follow-up.

This article discusses how the radiologist should handle the imaging for the post-treatment sarcoma patient. This includes reviewing the timing of surveillance after therapy and the type of therapy used for sarcoma in order to better understand the typical post-treatment changes on imaging versus sarcoma recurrence. The type of imaging is reviewed, especially, magnetic resonance imaging and the relevant sequences, as well as the appearance of post-treatment changes, sarcoma recurrence, and post-treatment complications.

Imaging Review of Subscapularis Tendon and Rotator Interval Pathology.

As the largest rotator cuff muscle, the subscapularis plays a major role in stabilizing the glenohumeral joint, in conjunction with surrounding rotator cuff structures. Injury to the subscapularis tendon can be isolated, but more commonly is seen in conjunction with supraspinatus tendon pathology. Injury can be associated with biceps pulley instability, superior labral anterior-posterior (SLAP) tears, humeral head subluxation, and anterosuperior and coracoid impingements.

Knee cartilage damage and concomitant internal derangement on MRI in athletes competing at the Rio de Janeiro 2016 Summer Olympics.

Purpose: To report the MRI patterns of knee cartilage damage and concomitant internal derangement in athletes participating at the Rio de Janeiro 2016 Olympic Games.

Methods: Knee MRIs obtained at the core imaging facility of the International Olympic Committee were blindly, retrospectively reviewed by a board-certified musculoskeletal radiologist for meniscal, ligamentous, and tendon abnormalities. Cartilage assessment was based on the modified Outerbridge criteria.

Online sequential echo state network with sparse RLS algorithm for time series prediction.

Recently, the echo state networks (ESNs) have been widely used for time series prediction. To meet the demand of actual applications and avoid the overfitting issue, the online sequential ESN with sparse recursive least squares (OSESN-SRLS) algorithm is proposed. Firstly, the ℓ and ℓ norm sparsity penalty constraints of output weights are separately employed to control the network size.

Multidetector Computed Tomography Imaging of Damage Control Surgery Patients.

Damage control surgery is a staged surgical procedure in a patient who has suffered penetrating or blunt abdominal traumatic injury with severe metabolic derangements. Multidetector computed tomography scanning is a vital tool for patient management in the damage control patient, providing many uses, including assessing the extent of traumatic injury, evaluating areas that were not surgically explored, evaluating for injuries that were missed during the initial surgery, and assessing the stability of surgical repair. Understanding the postsurgical multidetector computed tomography appearance of these patients can aid the radiologist in protocol optimization and provide immediate accurate diagnoses.
