True lateral imaging during lumbar medial branch radiofrequency neurotomy: Interobserver reliability.

Background: True lateral imaging (TLI), obtained by superimposing bilateral lumbar spine structures and aligning superior endplate cortical bone, requires deliberate rotational adjustments of the laterally positioned fluoroscope in both the axial and longitudinal planes. True lateral segmental imaging is necessary to depict true and accurate radiofrequency (RF) cannula positioning relative to bony anatomy during lumbar medial branch radiofrequency neurotomy (LMBRFN).

Objective: To determine the interobserver reliability of TLI during LMBRFN.

Encephalopathy after unintentional intrathecal gadolinium: A letter to the editor.

Objective: Raise awareness of gadolinium encephalopathy, a rare cause of neurological symptoms.

Setting: An L5-S1 interlaminar epidural steroid injection (IL-ESI) was performed with a gadolinium-based contrast agent (GBCA) due to the patient's history of allergic reaction to iodine-based contrast agents.

Discussion: Several hours after administration of GBCA, the patient had nausea and vomiting with altered mental status.

Recurrent ileocolic intussusception with appendiceal lead point in a 2-year-old child: an etiology to be aware of on ultrasound.

Ileocolic intussusception is a differential consideration in young pediatric patients presenting with acute abdominal pain. Appendiceal intussusception is an uncommon variant of ileocolic intussusception where the appendix is contained within the intussusception, which can be challenging to diagnose preoperatively. In this case report, we present a 25-month-old female presenting with intermittent, diffuse abdominal pain.

A proposed nomenclature for spinal imaging and interventional procedural reporting.

Objective: To develop precise universal standard interventional spine nomenclature for reporting procedural details and anatomy.

Methods: There is no comprehensive nomenclature of spinal imaging anatomy that can be used for anatomical and procedural reporting. Given this critical lack of unifying terminology, a system of nomenclature was developed de novo by expert consensus, based upon clinical needs, and previously published reports.

The pediatric stomach - congenital abnormalities.

Diagnostic imaging of the pediatric stomach often provides a challenge for practicing radiologists. Radiologists should be aware of relatively unusual congenital pathology, especially when imaging very young children with gastrointestinal symptoms. We review congenital pathology of the pediatric stomach.

Updates and Advances: Pediatric Musculoskeletal Infection Imaging Made Easier for Radiologists and Clinicians.

Infants and children often present with a wide range of musculoskeletal (MSK) infections in daily clinical practice. This can vary from relatively benign superficial infections such as cellulitis to destructive osseous and articular infections and life-threatening deep soft tissue processes such as necrotizing fasciitis. Imaging evaluation plays an essential role for initial detection and follow-up evaluation of pediatric MSK infections.

The pediatric stomach - masses and mass-like pathology.

Diagnostic imaging of pediatric gastric masses often provides a challenge for the practicing radiologist. Radiologists should be aware of this relatively unusual pathology, particularly in cross-sectional imaging findings. We will review pediatric gastric masses and mass-like lesions, focusing on neoplastic and inflammatory etiologies.

CT-guided biopsy of pulmonary nodules ≤10 mm: Diagnostic yield based on nodules' lobar and segmental distribution.

Purpose: The aim of our study is to evaluate the diagnostic performance of CT-guided biopsy of lung nodules ≤10 mm based on their lobar and segmental location.

Materials And Methods: This was a retrospective study performed on 193 CT-guided percutaneous transthoracic needle biopsies of lung nodules ≤10 mm in greatest dimension, between January 1, 2013 and April 30, 2019. Biopsies were classified as either diagnostic or non-diagnostic based on final cytology and surgical pathology reports.

Beyond Crohn Disease: Current Role of Radiologists in Diagnostic Imaging Assessment of Inflammatory Bowel Disease Transitioning from Pediatric to Adult Patients.

Inflammatory bowel disease (IBD) has a rising prevalence in children and an increasing number of adults living with IBD were diagnosed in childhood. This chronic disorder requires frequent cross-sectional imaging for evaluating disease progression. Radiologists must be vigilant to detect and understand imaging manifestations of acute and chronic, alimentary, and extraintestinal findings of IBD.

Subjective stability perception is related to postural anxiety in older subjects.

Background: Under static conditions, the objective and subjective measures of postural stability correlate well. However, age-related changes in postural control and task-related anxiety may modify the relationship between these subjective and objective measures. Ultimately, patients' symptoms represent subjective reports, thus understanding this relationship has clinical implications.

Electroencephalographic Correlates of Continuous Postural Tasks of Increasing Difficulty.

Cortical involvement in postural control is well recognized, however the role of non-visual afferents remains unclear. Parietal cortical areas are strongly implicated in vestibulo-spatial functions, but topographical localization during balance tasks remains limited. Here, we use electroencephalography (EEG) during continuous balance tasks of increasing difficulty at single electrode positions.

Induced lumbosacral radicular symptom referral patterns: a descriptive study.

Background Context: Lumbosacral radicular symptoms are commonly evaluated in clinical practice. Level-specific diagnosis is crucial for management. Clinical decisions are often made by correlating a patient's symptom distribution and imaging with sensory dermatomal maps.

Lumbosacral Transitional Segments: An Interventional Spine Specialist's Practical Approach.

The presence of a lumbosacral transitional vertebrae (LSTV) should prompt a more detailed preprocedural evaluation of the vertebral column to accurately determine spinal levels. An LSTV should prompt the use of corroborating intraprocedural imaging to verify morphology. The most important factors in treating lumbosacral transitional segments are communication among treating physicians to ensure segmental enumeration consistency and associated appropriate patient treatment.

Image and Contrast Flow Pattern Interpretation for Attempted Epidural Steroid Injections.

Fluoroscopically guided, contrast-enhanced epidural steroid injections (ESIs) are frequently performed for radicular symptoms. Interventionalists performing these procedures should have a thorough and detailed understanding of spinal anatomy to safely and effectively deliver the desired injectate to the targeted site. Being able to differentiate epidural from nonepidural contrast flow is vital as is recognizing flow to undesired locations.

Prognostic factors for advanced-stage human immunodeficiency virus-associated classical Hodgkin lymphoma treated with doxorubicin, bleomycin, vinblastine, and dacarbazine plus combined antiretroviral therapy: a multi-institutional retrospective study.

Background: The treatment and outcomes of patients with human immunodeficiency virus (HIV)-associated Hodgkin lymphoma (HL) continue to evolve. The International Prognostic Score (IPS) is used to predict the survival of patients with advanced-stage HL, but it has not been validated in patients with HIV infection.

Methods: This was a multi-institutional, retrospective study of 229 patients with HIV-associated, advanced-stage, classical HL who received doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) plus combination antiretroviral therapy.
