ACR Appropriateness Criteria® Chronic Hip Pain: 2022 Update.

Chronic hip pain is a frequent chief complaint for adult patients who present for evaluation in a variety of clinical practice settings. Following a targeted history and physical examination, imaging plays a vital role in elucidating the etiologies of a patient's symptoms, as a wide spectrum of pathological entities may cause chronic hip pain. Radiography is usually the appropriate initial imaging test following a clinical examination.

A multicenter retrospective study assessing progression of biliary sludge in dogs using ultrasonography.

Background: Biliary sludge (BS) frequently is identified on ultrasonographic examination and is described as incidental. It is hypothesized that biliary stasis and hypersecretion play a role in both BS and gallbladder mucocele (GBM) formation. Recent studies have documented similarities in composition of BS and GBM, and there are several examples of progression from BS to GBM in the veterinary literature.

Incidence of cervical spine fractures on CT: a study in a large level I trauma center.

Introduction/purpose: Though spinal fractures constitute a minority of all traumas, the financial burden imposed is immense especially following cervical spine trauma. There have been several papers in the past describing the incidence of cervical spine fractures. In this paper, we report the incidence of cervical spine fractures and correlate with demographic information and cause of injury and review the mechanism of fractures.

Is elevated body mass index protective against cervical spine injury in adults?

Purpose: Correlate body mass index (BMI) with incidence and type of cervical spine injury seen on CT in adult patients presenting with blunt trauma.

Materials And Methods: Retrospective chart review of all adult blunt trauma patients who had a cervical spine CT performed at our level 1 trauma center during an approximately 3-year period.

Results: A statistically significant (p = 0.

Use of computed tomography imaging during long-term follow-up of nine feline tuberculosis cases.

Case series summary Feline tuberculosis is an increasingly recognised potential zoonosis of cats. Treatment is challenging and prognosis can vary greatly between cases. Pulmonary infection requires extended courses of antibiotics, but methodologies for sensitively monitoring response to treatment are currently lacking.

Validation and determination of a reference interval for canine HbA1c using an immunoturbidimetric assay.

Background: Hemoglobin A1c (HbA1c) provides a reliable measure of glycemic control over 2-3 months in human diabetes mellitus. In dogs, presence of HbA1c has been demonstrated, but there are no validated commercial assays.

Objective: The purpose of the study was to validate a commercially available automated immunoturbidimetric assay for canine HbA1c and determine an RI in a hospital population.

Osseous Scaphotrapezial Coalition.

Osseous scaphotrapezial coalition is one of the rarest forms of carpal coalition of the hand. Often discovered incidentally, pain and functional limitation have not been reported. Carpal coalitions occurring across the carpal rows are thought to occur as a result of some insult or congenital anomaly.

Unusual Presentations of Focal Periphyseal Edema Zones: A Report of Bilateral Symmetric Presentation and Partial Physeal Closure.

Focal periphyseal edema (FOPE) zones are areas of periphyseal edema seen near the time of physeal closure which are believed to be a physiologic phenomenon related to changes in distribution of forces around the physis as it closes. Since the original case series describing these areas of periphyseal edema, there has been little published in regard to FOPE zone outside of review articles. We present a set of three patients identified with focal periphyseal edema zones around the knee and compare our findings with the initial case series.

Core curriculum illustration: posterior column acetabular fracture.

This is the 17th installment of a series that will highlight one case per publication issue from the bank of cases available online as part of the American Society of Emergency Radiology (ASER) educational resources. Our goal is to generate more interest in and use of our online materials. To view more cases online, please visit the ASER Core Curriculum and Recommendations for study online at: http://www.

Congenital indifference to pain: an illustrated case report and literature review.

Congenital indifference to pain is a rare and debilitating congenital disease. Individuals with the disorder may have one or a combination of sensory or autonomic deficits, which can range from lack of mechanical nociception, diminished ability to detect heat and cool stimulation, to the devastating and fatal form which includes autonomic dysfunction. It is important for radiologists to be able to recognize the radiographic presentations of this rare disorder, as delay in diagnosis can lead to extensive and sometimes unnecessary workup.

Traumatic portacaval shunt: a case report and literature review.

Computed tomography (CT) evaluation of the acute polytrauma patient has become well established as a mainstay of ER triage in hemodynamically stable patients. The radiologist plays a pivotal role in directing management by identifying and appropriately categorizing the severity of a patient's injuries. High-grade liver injuries have undergone an increasing trend of nonoperative management over the last several decades, with concurrent decrease in mortality.

Emergent right upper quadrant sonography.

Objective: The purpose of this presentation is to review the sonographic spectrum of disease entities evaluated by right upper quadrant (RUQ) sonography on an emergent basis.

Methods: Right upper quadrant sonography was performed on an emergent basis in patients who came to the emergency department with signs and symptoms suspicious for or simulating acute cholecystitis or diseases of the liver and biliary tree.

Results: A wide gamut of acute and chronic cholecystitis and diseases of the liver and biliary tree were visualized on RUQ sonography.
