OBJECTIVES: Sonography has been suggested as a possible means of endotracheal tube (ETT) placement confirmation. However, optimum ultrasound transducer placement has not been established. Using a cadaveric model, ETT placement by the sonographic appearance at the thyroid cartilage, cricoid cartilage, and suprasternal notch in the upper airway was assessed to determine which ultrasound transducer placement offered the most optimal images for ETT confirmation in the airway. METHODS: One provider intubated 5 cadavers, with the ultrasound transducer at each of the 3 levels, for a total of 30 intubations per specimen, while 2 providers assigned a visual score of 1 (subtle), 2 (clear), or 3 (pronounced) to each sonogram of the ETT in the airway...

We evaluated nodular fasciitis (NF) in 19 patients, focusing on the correlation between its sonographic and histopathologic features. Sonograms were retrospectively reviewed, and the location, shape, margin, echogenicity, echogenic rim, peripheral hyper-echoic nodules, posterior enhancement and vascularity of the lesions were recorded. In the histopathologic analysis, three patterns-infiltrating, pushing border and well circumscribed-were identified, and culture-like tissue centers were classified according to the distribution of focal keloid-like collagen bundles: uneven or even...

The preimplantation ultrasound (US) refers to targeted imaging of the uterus and adnexa prior to assisted reproductive techniques (ART) to optimize the infertility treatment outcomes. After a thorough evidence based literature review, we propose the use of transvaginal three-dimensional (3D) US during the early follicular phase. A systematic approach for 3D US examination consists of a detailed examination of the uterine shape, size and contour, evaluation of the endometrial thickness, volume, pattern and vascularity, and assessment of the junctional zone regularity, echogenicity and thickness...

OBJECTIVES: To evaluate sonographic findings as indicators of complicated versus uncomplicated appendicitis in the setting of known appendicitis, a necessary distinction in deciding whether to proceed with antibiotic therapy or with appendectomy. METHODS: With Institutional Review Board approval and Health Insurance Portability and Accountability Act compliance, appendiceal sonograms of 119 patients with histopathologically proven appendicitis were retrospectively blindly reviewed to determine the presence or absence of the normally echogenic submucosal layer, the presence of mural hyperemia, periappendiceal fluid, appendicoliths, and hyperechoic periappendiceal fat and to determine the maximum outside diameter...

PURPOSE: To show the feasibility of acquiring high-resolution sagittal ultrasound (US) images of the temporomandibular joint (TMJ). PATIENTS AND METHODS: We used commercially available US probes to assess the TMJ via a transoral soft tissue window to acquire sagittal images. Magnetic resonance imaging and clinical correlation were compared with the US findings by the consensus assessment of 2 of the senior investigators. RESULTS: The sample was composed of 10 TMJs (6 participants) with an age range of 34 to 71 years and a male-female ratio of 3:1...

BACKGROUND: Operative intervention is the preferred option for management of the neglected laceration of the Achilles tendon. However, the commonly used techniques rarely follow the principles of the regenerative medicine for the restoration of the lost tissue. This study postulated that incorporation of the autogenous tendon graft would properly progress when the interplay between mechanical loading and healing phases was correctly applied. METHODS: A prospective study included 15 patients who were treated for neglected Achilles tendon laceration using the technique of lengthening of the proximal tendon stump...

The objective of this pictorial essay is to systematically classify processus vaginalis-related disorders in the light of embryology and present illustrative sonograms with corresponding diagrams. Failure of the processus vaginalis to obliterate during gestation results in a wide spectrum of anomalies, including communicating and noncommunicating hydroceles and inguinal and inguinoscrotal hernias, along with other related disorders of the genital system. There are varying classifications in the literature regarding the aforementioned entities...

OBJECTIVES: Accurate pregnancy dating is critical for appropriate clinical management. Our aim was to determine the time of appearance of PHE, consistency of its appearance among ethnic groups, and whether 3D imaging helps with its visualization. METHODS: A cross-sectional study was done on 360 patients with 563 scans in different ethnic groups between August 2013 and July 2015. INCLUSION CRITERIA: Singleton pregnancies (34-40+ weeks of gestation), well dated by < 20 weeks sonogram...

PURPOSE: Maternal hydronephrosis may cause flank pain during pregnancy. We aimed to investigate the association between maternal hydronephrosis and flank pain intensity. METHODS: From 2014 to 2015, all consecutive women with singleton pregnancies, who presented at our tertiary center due to acute flank pain, were prospectively evaluated by renal ultrasonography and pain questionnaires. A visual analogue scale was used to assess pain intensity. The study had 90% power to detect a significant correlation between hydronephrosis and flank pain (Spearman's test)...

In spite of recent advances in treatment protocols, tendinopathies continue to challenge orthopaedists and surgeons. Due to the complexity of both tendon injuries and the healing processes, animal models are essential for addressing fundamental questions in tendinopathy research. Diagnostic imaging could contribute to the evaluation of animal models, thus providing information, which could be translated to human tendinopathies. The objective of our study was to evaluate in situ appearance of the rabbit common calcanean tendon with ultrasonography and magnetic resonance imaging...
