Aims: A meaningful sonographic examination is decisively dependent on the B-scan quality of the ultrasound device. When selecting a suitable ultrasound device, B-scan quality should be an important purchase criterion. Although there is no generally accepted method to measure B-scan quality, we tried to evaluate comparable sonography devices from different manufacturers regarding B-scan quality.Material and methods: We systematically assessed the B-scan quality in ultrasound devices of seven different manufacturers from the mid-price segment. All 7 ultrasound units tested had comparable equipme

The aim of this study was to analyze the use of the diagnostic B-scan ultrasound. Should it be made accessible to all surgical centers in Sub-Saharan Africa in order to (i) avoid unnecessary cataract surgery and (ii) evaluate extraocular pathology? This study was conducted in Kinshasa from 2006 to 2019. Three hundred and twenty-three patients were included and separated into two groups. Group 1 included 262 patients with dense cataract. Group 2 consisted of 61 patients with pathologies of the ocular adnexa, and all were examined with a B-scan ultrasound. In group 1, there were 437 systematical

Abstract Purpose The quality of an ultrasound device’s B-scan mode is decisive in obtaining clear and informative images. High demands are placed upon ultrasound devices, particularly in cases where evidence of small lesions of parenchymal organs is being gathered. Methods We tested the quality of the B-scan mode in ultrasound devices of 7 different manufacturers. We performed ultrasound examinations of 3 predefined abdominal sections on 4 healthy subjects with 7 different ultrasound devices. Documentation was compiled digitally by recording video sequences.

Background: Positron emission tomography (PET) with 18F-FDG is being used more frequently to evaluate primary pelvic tumors (PTs). However, a standardized hydration protocol is essential for an optimal diuretic effect and constant results. Methods: We reviewed 109 patients with PTs who had undergone 18F-FDG PET/CT examinations between November 2006 and April 2013. Four different protocols were used: (a) no hydration (group 1); (b) oral hydration (800 mL) after an early scan (group 2); (c) intravenous (IV) hydration (500 mL) during an early scan followed by oral hydration (800 mL) and IV furose

Optic nerve aplasia is a rare developmental anomaly characterised by the congenital absence of the optic nerve, central retinal vessels and retinal ganglion cells that is seen most often in a unilaterally malformed eye. Case report. We reported a girl with a very rare anomaly of the eye, unilateral aplasia of the optic nerve and microphthalmia. We carried out a complete ophthalmological examination, A- and Bscan ultrasonography, magnetic resonance imaging (MRI) of the orbit and brain, pediatrician, neurological examinations and karyotype determination.

In this case report, we describe a 53-year-old woman who presented with a slow-growing lower lid mass in her right eye. On gross examination, a remarkable lower lid bulging was noted. On palpation, a subcutaneous oval-shaped mass with a firm consistency, measuring about 2cm, was noted. The uncorrected visual acuities of the patient were 20/20 (by Snellen chart) bilaterally, and the examinations of the anterior and posterior segments of both eyes were unremarkable.

The onset of the COVID-19 pandemic allowed physicians to gain experience in lung ultrasound (LUS) during the acute phase of the disease. However, limited data are available on LUS findings during the recovery phase. The aim of this study was to evaluate the utility of LUS to assess lung involvement in patients with post-COVID-19 syndrome. This study prospectively enrolled 72 patients who underwent paired LUS and chest CT scans (112 pairs including follow-up). The most frequent CT findings were ground glass opacities (83.3%), subpleural lines (72.2%), traction bronchiectasis (37.5%), and consol

Background: Significant coronary artery disease (CAD) is a common finding in patients undergoing transcatheter aortic valve implantation (TAVI). Assessment of CAD prior to TAVI is recommended by current guidelines and is mainly performed via invasive coronary angiography (ICA). In this study we analyzed the ability of coronary CT-angiography (cCTA) to rule out significant CAD (stenosis ≥ 50%) during routine pre-TAVI evaluation in patients with high pre-test probability for CAD.

Introduction. The presence of bilateral exophthalmos and palpebral, periorbital edema associated with hyperthyroidism is most often considered as an initial sign of Graves? ophthalmopathy. However, in up to 20% of cases, Graves? ophthalmopathy might precede the occurrence of hyperthyroidism, which is very important to be considered in the differential diagnosis, especially if it is stated as unilateral. Among other less common causes of non-thyroid-related orbitopathy, orbital lymphoma represents rare conditions. We presented of a patient with Graves? disease, initially manifested as bilateral

Relevance: сurrently, micropulse transscleral cyclophotocoagulation is widely used for the treatment of refractory glaucoma. It has a high safety profile and can be applied to eyes with high visual potential. Continuous-wave cyclophotocoagulation has a more pronounced hypotensive effect; however, it is accompanied by a significant number of complications. During transscleral cyclophotocoagulation, it is suggested to use a standard position for the sensor, though the position of the ciliary processes may vary.Purpose: to analyze the effectiveness and safety of the combined cyclophotocoagulation

However, interpretation of Doppler signals in children is challenging due to physiologic vascularization that can be misinterpreted as pathologic findings. Definitions for synovitis in children, including B-mode (BM) and Doppler findings, have been developed and emphasize that only Doppler signals within synovial hypertrophy should be considered as synovitis [1]. So far, few studies have implemented this definition in the evaluation of Doppler findings in children.Object

Abstract A number of prognostically important genetic subtypes of acute lymphoblastic leukemia (ALL) has been identified. Most notably, the presence of t(9;22)/BCR-ABL1 or 11q23/MLL rearrangements in B-cell ALL is a poor prognostic indicator and patients with these subtypes of ALL are candidates for allogeneic stem cell transplantation. Consequently, early detection of minimal residual disease (MRD) is critical for appropriate diagnostic and therapeutic decisions.
