Neuroimaging of central diabetes insipidus.

Central diabetes insipidus (CDI) occurs secondary to deficient synthesis or secretion of arginine vasopressin peptide from the hypothalamo-neurohypophyseal system (HNS). It is characterized by polydipsia and polyuria (urine output >30mL/kg/day in adults and >2l/m/24h in children) of dilute urine (<250mOsm/L). It can result from any pathology affecting one or more components of the HNS including the hypothalamic osmoreceptors, supraoptic or paraventricular nuclei, and median eminence of the hypothalamus, infundibulum, stalk or the posterior pituitary gland.

Lateral femoral condyle insufficiency fractures: imaging findings, demographics, and analysis of outcomes.

Objective: To describe imaging characteristics and demographics of lateral femoral condyle insufficiency fractures (LFCIFs) and identify characteristics associated with progression to epiphyseal collapse.

Materials And Methods: A retrospective review of 105 consecutive patients with LFCIF was performed (mean age 58.1 years) after excluding post-traumatic and pathological fractures.

Acromioclavicular Joint: What to Look for.

Acromioclavicular joint (ACJ) pathology is a common source of shoulder girdle pain, frequently coexisting with and sharing overlapping clinical features of rotator cuff and glenohumeral articular lesions. ACJ trauma and osteoarthritis dominate clinical presentation; however, an array of pathologies can affect the joint. MR imaging of the ACJ is a powerful secondary diagnostic tool in early diagnosis of ACJ pathology and in accurate assessment of ACJ injuries, helping to resolve clinically challenging cases and allowing for individualized treatment planning.

Comparison of outcomes and cost-effectiveness of trisacryl gelatin microspheres alone versus combined trisacryl gelatin microspheres and gelatin sponge embolization in uterine fibroid embolization.

Background: Uterine fibroid embolization (UFE) is an effective treatment for uterine leiomyomata. Optimizing the choice of embolic agents is imperative to achieve better patient outcomes with maximum resource utilization.

Purpose: To evaluate the efficacy and cost-effectiveness of trisacryl gelatin microspheres (TAGM) versus combined TAGM and gelatin sponge (GS) embolization in the treatment of symptomatic uterine leiomyomata.

Musculoskeletal Imaging: Current Practice and Future Directions.

Musculoskeletal (MSK) radiology plays a crucial role in the diagnosis and management of MSK disorders and has rapidly expanded in tandem with advances in technology and improved access to imaging. Although anatomical imaging remains the mainstay of MSK radiology, significant progress has been made in functional and molecular imaging as well as in hybrid imaging with an expanding armament of technologies becoming available or in development. A vast array of research is occurring in MSK imaging, and this review article highlights some of the most promising current and future clinical applications in development in each of the major imaging modalities.

Therapeutic Intervention in Musculoskeletal Radiology: Current Practice and Future Directions.

Over the last several decades, the volume and range of therapeutic musculoskeletal (MSK) interventions that radiologists can offer their patients has dramatically increased. With new materials and improving imaging modalities, as well as significant investment in research, the field of MSK interventional radiologic intervention will likely continue to expand. In this article, we summarize the range of interventions currently available to the MSK radiologist.
