Background: Ultrasonographic soft markers are normal variants, rather than fetal abnormalities, and guidelines recommend a detailed survey of fetal anatomy to determine the necessity of antenatal karyotyping. Anecdotal reports have described cases with ultrasonographic soft markers in which chromosomal microarray analysis (CMA) revealed pathogenic copy number variants (CNVs) despite normal results on conventional karyotyping, but CMA for ultrasonographic soft markers remains a matter of debate. In this systematic review, we evaluated the clinical significance of CMA for pregnancies with isolated ultrasonographic soft markers and a normal fetal karyotype.
Methods: An electronic search was conducted by an experienced librarian through the MEDLINE, Embase, and Cochrane CENTRAL databases. We reviewed 3,338 articles (3,325 identified by database searching and 13 by a hand search) about isolated ultrasonographic soft markers, and seven ultrasonographic markers (choroid plexus cysts, echogenic bowel, echogenic intracardiac focus, hypoplastic nasal bone, short femur [SF], single umbilical artery, and urinary tract dilatation) were included for this study.
Results: Seven eligible articles were included in the final review. Pathogenic or likely pathogenic CNVs were found in fetuses with isolated ultrasonographic soft markers and a normal karyotype. The overall prevalence of pathogenic or likely pathogenic CNVs was 2.0% (41 of 2,048). The diagnostic yield of CMA was highest in fetuses with isolated SF (9 of 225, 3.9%).
Conclusion: CMA could aid in risk assessment and pregnancy counseling in pregnancies where the fetus has isolated ultrasonographic soft markers along with a normal karyotype.

Objective: To describe the clinical and ultrasonographic findings in horses with desmopathy of the abaxial palmar/plantar ligament (APL) of the proximal interphalangeal joint and the prevalence of concurrent musculoskeletal injuries in the pastern and foot.
Animals: Horses presenting to New Bolton Center between March 2017 and November 2022 with an age ranging from 5 to 20 years that underwent lameness evaluation in which lameness was localized to the distal limb and had an ultrasonographic diagnosis of APL desmopathy.
Clinical Presentation: Horses included were those that (1) presented for a lameness examination; (2) had lameness that improved after diagnostic analgesia with a low 4-point nerve block (medial and lateral palmar/plantar nerves and medial and lateral palmar/plantar metacarpal/metatarsal nerves), abaxial sesamoid nerve block (medial and lateral palmar or plantar nerves), or palmar/plantar digital nerve block; and (3) had an ultrasonographic diagnosis of APL desmopathy.

Purpose: This study aimed to determine the suitability and optimal concentration of an ultrasonic contrast agent (SonoVue) for intralesional application during contrast-enhanced ultrasonography (CEUS).
Methods: An in vitro model simulating an existing lesion in the anatomical environment of the mandibular ascending ramus was developed. After intralesional application, different SonoVue dilutions were compared with dilutions of an iodine-containing radiographic contrast agent (Imeron300) during cone-beam computed tomography.

Background: To reveal the radiodensity and sonographic characteristics of various foreign bodies and dental materials to aid in the diagnosis of these materials.
Methods: The study included 41 objects consisting of various foreign bodies and dental materials. The objects were examined by embedding them in bovine gelatin, an in vitro environment and their radiodensity was evaluated using cone-beam computed tomography (CBCT).

Background: Diagnosing and characterizing breast lesions and tumors remains a common challenge in clinical practice. Ultrasound imaging stands out for its safety, real-time capability, and affordability. However, the image quality of conventional ultrasound examination is limited, and the diagnosis of ultrasonographic images depends heavily on the experience of the sonographer.

Background: Amyloid arthropathy is characterized by the deposition of misfolded proteins in the joints and soft tissues. It is often a manifestation of light chain amyloidosis. The ultrasonographic features of amyloid arthropathy are solely reported in the literature.
