Magnetic resonance imaging (MRI) is frequently used in the imaging evaluation of wrist pain. The complex anatomy of the wrist can be demonstrated by MRI. Three tesla (3 T) MRI offers increased signal-to-noise ratio relative to 1.5 T MRI allowing for higher soft tissue contrast and better spatial resolution. The resulting increase in conspicuity of fine anatomic detail may improve the detection and characterization of wrist pathology. In this article, we will review the anatomy, normal variants, and common pathologies of the wrist tendons as evaluated on 3 T MRI.
Objectives: Obesity is a progressive chronic disease associated with many serious complications. Objectives of this study were to assess the incidence proportion (IP) and period prevalence (PP), and quantify complication-specific costs in the 1-year following diagnosis, for 13 obesity-related complications (ORCs) by BMI class. Methods: Adult patients ($18 years) with $1 recorded BMI value were identified using linked US data from IQVIA's Ambulatory Electronic Medical Records and Real-World Data Adjudicated Claims -US Database. ORCs were identified using ICD-9/10 diagnosis codes. IP and PP for ORCs were assessed in each calendar year from 2010-2017. Incidence was defined based on absence of ORC diagnosis codes in the prior calendar year. For the cost assessment, the first date of an ORC diagnosis from 1/ 2010-12/2016 defined the index date. Patients with continuous enrollment 1-yearpre-index (without ORC diagnosis) and 1-year-post-index and $1 recorded BMI value in the 6-month-pre-index were included. Complication-specific cost over the 1-year-post-index (reported in 2017 USD) included claims with a diagnosis code for the specific ORC (primary position for hospitalizations) and ORC-specific medications and procedures. Underweight patients (BMI,18.5 kg/m 2 ) were excluded. Descriptive analyses were conducted for complications overall and by BMI class. Results: The two most common ORCs based on IP and PP were musculoskeletal pain (overall range across years IP:
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
