Building a Tree From the Leaves Down: A Challenge for Contemporary Educators.

Repeatability and comparability of peripapillary vessel density measurements of high-density and non-high-density optical coherence tomography angiography scans in normal and glaucoma eyes.

To compare the peripapillary vessel density (VD) measurements of high-density (HD) and non-HD optical coherence tomography angiography (OCTA) scans in normal and glaucoma eyes, and to evaluate the intrasession repeatability of VD measurements of HD scans.

Differential diagnosis of posterior fossa tumours in children: new insights.

Central nervous system neoplasms are the most common solid tumours that develop in children, with the greatest proportion located in the infratentorium. The 2016 World Health Organization Central Nervous System tumour classification evolved from the 2007 edition with the integration of molecular and genetic profiling into the diagnosis, the addition of new entities and the removal of others. Radio...

Inter-radiologist agreement using Society of Abdominal Radiology-American Gastroenterological Association (SAR-AGA) consensus nomenclature for reporting CT and MR enterography in children and young adults with small bowel Crohn disease.

To assess inter-radiologist agreement using the Society of Abdominal Radiology-American Gastroenterological Association (SAR-AGA) consensus recommendations for reporting CT/MR enterography exams in pediatric and young adult small bowel Crohn disease (CD).

Ultrasound Evaluation of Puncture Sites After Deployment of Two Different Types of Vascular Closure Devices: A Prospective Comparative Study.

The aim of this study was to compare the ultrasonographic findings of femoral puncture sites and the complications of Perclose ProGlide and FemoSeal™ after neurointerventional procedures.

Antiplatelet Therapy is Associated with Stent Patency After Iliocaval Venous Stenting.

To examine the effectiveness of antithrombotic medications to prevent venous stent malfunction for iliocaval occlusive disease.

InCl-catalyzed one-pot synthesis of multi-substituted pyrano2,3-cpyrazole-4-carboxylic acid esters under ultrasound irradiation.

An efficient and simple procedure for the synthesis of 6-amino-5-cyano-4-phenyl-pyrano[2,3-c]pyrazole-4-carboxylic acid esters was developed via a one-pot reaction of β-ketoester, hydrazine, benzoylacetate, and malononitrile in 50% EtOH catalyzed by InCl under ultrasound irradiation. This method is more economic, convenient, nontoxic, and environmentally friendly than established methods of pyran...

Guest editorial for the IJCARS special issue on MICCAI 2017.

Ultrasound imaging of the anorectal malformation during the neonatal period: a comprehensive review.

Anorectal malformation (ARM) is classified as low, intermediate, or high; accurate diagnosis of the type during the early neonatal period is important to determine the appropriate initial surgical approach. This review assesses the role of ultrasound examination in the classification of ARM during the neonatal period, with a focus on landmarks on the sonogram, the approach used for sonography, and...

Ultrasound elastography: compression elastography and shear-wave elastography in the assessment of tendon injury.

Ultrasound elastography (USE) is a recent technology that has experienced major developments in the past two decades. The assessment of the main mechanical properties of tissues can be made with this technology by characterisation of their response to stress. This article reviews the two major techniques used in musculoskeletal elastography, compression elastography (CE) and shear-wave elastograph...

The influence of anthropometric and basic circulatory variables on count rate in cadmium-zinc-telluride SPECT gated radionuclide angiography.

To determine the influence of weight, height, gender, age, heart rate, and blood pressure on count rate in cadmium-zinc-telluride single-photon emission computed tomography (CZT SPECT) gated radionuclide angiography.

Diagnostic protocols for the management of pregnancy of unknown location.

'Pregnancy of unknown location' is a non-diagnostic transvaginal ultrasound scan in early pregnancy. The scan may be non- diagnostic because the pregnancy is too small to identify, too difficult to identify or gone - already passed during the process of miscarriage. Many patients are surprised to learn that urine pregnancy tests are more sensitive in detecting a pregnancy than ultrasound scans, bu...

EUS-guided celiac ganglion radiofrequency ablation versus celiac plexus neurolysis for palliation of pain in pancreatic cancer: a randomized controlled trial (with videos).

Although frequently performed, the efficacy of endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) for palliation of pain in pancreatic cancer is suboptimal. Recently, endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has been proposed as a palliative treatment option for pancreatic neoplasms. We performed a single-blind, randomized trial to compare the effectiveness of EU...

Many Options for Endoscopic Ultrasound-guided Fine-needle Aspiration of Pancreatic Masses, But Any Differences?"

Therapeutic efficacy of early photobiomodulation therapy on the zones of stasis in burns: An experimental rat model study.

This study aimed to investigate the role of photobiomodulation therapy in preventing zones of stasis in burn wounds. We hypothesized that photobiomodulation therapy could promote tissue formation and release of nitric oxide (NO) through a photochemical reaction, and reduce local inflammatory responses, thereby dilating local microvessels, reducing necrosis and apoptosis. Thirty rats were randomly ...

Testing for AFP in combination with ultrasound improves early liver cancer detection.

Iris microhemangiomatosis: Clinical, fluorescein angiography, and optical coherence tomography angiography in 14 consecutive patients.

To describe the clinical and imaging findings and treatment options in a series of patients with iris microhemangiomatosis.

Topographical Analysis of the Choriocapillaris in Intermediate Age-related Macular Degeneration.

To quantitate regional differences in the choriocapillaris (CC) of patients with intermediate age-related macular degeneration (iAMD), using swept source-optical coherence tomography angiography (SS-OCTA) imaging.

3D functional ultrasound imaging of pigeons.

Recent advances in ultrasound Doppler imaging have facilitated the technique of functional ultrasound (fUS) which enables visualization of brain-activity due to neurovascular coupling. As of yet, this technique has been applied to rodents as well as to human subjects during awake craniotomy surgery and human newborns. Here we demonstrate the first successful fUS studies on awake pigeons subjected ...

Acute skeletal muscle wasting and relation to physical function in patients requiring extracorporeal membrane oxygenation (ECMO).

Muscle weakness is common in patients requiring extracorporeal membrane oxygenation (ECMO), but early identification is challenging. This study aimed to 1) quantify the change in quadriceps size and quality (echogenicity) from baseline to day 10 using ultrasound in patients requiring ECMO, 2) determine the relationship between ultrasound measures, muscle strength and highest mobility level.

Synthesis, biological activity and structure activity relationship studies of novel conazole analogues via conventional, microwave and ultrasound mediated techniques.

1,2,4-Triazole derivatives containing a piperazine nucleus (4a-d and 10) were prepared starting from 1-(2-methoxyphenyl)piperazine or ethyl 4-(4-amino-2-fluorophenyl)piperazine-1-carboxylate via several steps. The synthesis of fifteen compounds (7a-l and 13a-c), which can be considered as new analogues of azole class antifungals was performed starting from 1,2,4-triazoles (4a-d and 10) via three s...

The Value of 16-cm Wide-Detector Computed Tomography in Coronary Computed Tomography Angiography for Patients With High Heart Rate Variability.

The aim of this study was to investigate radiation dose and image quality of coronary computed tomography (CT) angiography (CCTA) for patients with high heart rate variability (HRv) using 16-cm wide-detector CT scanner.

Mediastinitis following EBUS : about a complication after a minimally invasive investigation.

Endobronchial ultrasound (EBUS) is a minimally invasive investigation method that permits transbronchial needle aspiration (TBNA) of mediastinal and hilar lymphadenopathies in order to determine their etiology. Its indications are notably lung cancer staging and lymphadenopathy exploration in case of sarcoidosis and malignant lymphomas. The employment of EBUS-TBNA has grown over the past few years...
