High-frequency ultrasound for diagnosing skin cancer in adults.

Early, accurate detection of all skin cancer types is essential to guide appropriate management and to improve morbidity and survival. Melanoma and squamous cell carcinoma (SCC) are high-risk skin cancers with the potential to metastasise and ultimately lead to death, whereas basal cell carcinoma (BCC) is usually localised, with potential to infiltrate and damage surrounding tissue. Anxiety around...

Automatic classification of pediatric pneumonia based on lung ultrasound pattern recognition.

Pneumonia is one of the major causes of child mortality, yet with a timely diagnosis, it is usually curable with antibiotic therapy. In many developing regions, diagnosing pneumonia remains a challenge, due to shortages of medical resources. Lung ultrasound has proved to be a useful tool to detect lung consolidation as evidence of pneumonia. However, diagnosis of pneumonia by ultrasound has limita...

Randomized clinical study on radial artery compression time after elective coronary angiography.

to compare two compression times of the radial artery after coronary angiography with customized compressive dressing regarding the occurrence of hemostasis and vascular complications.

Magnetically-propelled hydrogel particle motors produced by ultrasound assisted hydrodynamic electrospray ionization jetting.

One of the most promising future applications of hydrogels is drug delivery. The hydrogels act as a biomedical cargo model to reach the target and release drugs to cure diseases. This application requires no side effects of the hydrogel and the ability to pass through porous media (e.g. membranes, interstitial tissue etc.) with nanoscaled channels. At the same time, the hydrogel must be mass-produ...

Correlation of Ultrasound Findings and Fine-Needle Aspiration Cytology for the Diagnosis of Axillary Lymph Node Metastasis in Patients with Breast Carcinoma.

Ultrasound-guided fine-needle aspiration cytology (USG-FNAC) is used for the detection of axillary lymph node (ALN) metastasis in patients with breast carcinoma (BC). US findings have a good diagnostic accuracy with high sensitivity and specificity. The aim of this study is to correlate the detection of ALN metastases on US with FNAC in BC patients.

The on-site differential diagnosis of decompression sickness from endogenous cerebral ischaemia in an elderly Ama diver using ultrasound.

Commercial or occupational breath-hold (BH) harvest divers along the coast and islands of Japan are collectively called Ama divers. Repetitive BH diving by Ama divers may place them at risk of developing neurological decompression sickness (DCS). We report a 74-year-old Ama diver who demonstrated right hemiparesis during an ascent after free diving at a depth of 5 metres' sea water. This report su...

PET in Lymphoma: Making a Difference in Patients' Lives.

Repeat Contrast Medium Administration for Patients with Mild Immediate Hypersensitivity Reaction to Iodinated Contrast Media.

CT Manifestations of Tumor Spread through Air Spaces in Lung Adenocarcinoma: Different Pathways toward Common Perspectives.

Diagnostic Case-Control versus Diagnostic Cohort Studies for Clinical Validation of Artificial Intelligence Algorithm Performance.

Optic nerve ultrasound for fluid status assessment in patients with severe preeclampsia.

Background There are no data on usefulness of optic nerve sheath diameter (ONSD) as a marker of patient's fluid status in preeclampsia. The objective was to examine potential correlation between ONSD and lung ultrasound estimates of extravascular lung water in severe preeclampsia. Patients and methods Thirty patients with severe preeclampsia were included. Optic and lung ultrasound were performed ...

On the Need for a Taxonomy for Interventional Radiology: Initiating Dialogue for the Future.

Interventional radiology (IR) needs comprehensive structure. The reactive structure of the past is strategically unwise for long-term growth of IR.

Health professionals' experiences and views on obstetric ultrasound in Rwanda: A cross-sectional study.

Implementation of ultrasound in antenatal care (ANC) in low-income countries has been shown to increase pregnant women's compliance with ANC visits, and facilitate detection of high-risk pregnancies. In Rwanda, as in other low-income countries, access to ultrasound has increased significantly, but lack of training is often a barrier to its use. The aim of this study was to investigate Rwandan heal...

Optical Coherence Tomography Angiography in Familial Exudative Vitreoretinopathy: Clinical Features and Phenotype-Genotype Correlation.

To evaluate the microstructure of the fovea in patients with familial exudative vitreoretinopathy (FEVR) compared to healthy controls using optical coherence tomography angiography (OCTA).

A man with a painful right shoulder.

Posterior sternoclavicular luxations are uncommon and potentially life threatening. When clinically suspected, a computed tomography angiography is the gold standard to investigate whether important structures located in the mediastinum are at risk. A fast reduction should be performed to reduce pain and prevent acute and late complications.

Reply: Ultrasound Technology in Targeting Reflux-Free Venules for Optimal Lymphaticovenular Anastomosis in the Treatment of Lymphedema.

Assessing subcutaneous adipose tissue by simple and portable field instruments: Skinfolds versus A-mode ultrasound measurements.

This study compared subcutaneous adipose tissue (SAT) measurements using a skinfold caliper and Renco Lean-Meater Series 12 A-mode portable ultrasound scanner (A-US). It aimed to assess their inter- and intra-rater reliability and measure the agreement between both methods.

Siewert type I and II oesophageal adenocarcinoma: sensitivity/specificity of computed tomography, positron emission tomography and endoscopic ultrasound for assessment of lymph node metastases in groups of thoracic and abdominal lymph node stations.

In Siewert type I/II oesophageal adenocarcinoma, the sensitivity and specificity of computed tomography (CT), positron emission tomography (PET)-CT and endoscopic ultrasound (EUS) for assessment of the N descriptor in defined groups of lymph nodes were investigated.

Do We Need Activity Scores or Simply Clear Criteria for Intestinal Ultrasound in Ulcerative Colitis?

Simultaneous flap thinning with ultrasound-assisted liposuction during free flap surgery: Preliminary results.

Ultrasound-assisted liposuction (UAL) has been previously used for postoperative flap thinning. Although it had been reported that UAL causes less damage to the vessels, the simultaneous use of UAL with free flap reconstruction has not been reported. The aim of this report was to determine the results and the complication rates of simultaneous use of UAL with free flap reconstruction.

A green approach for alginate extraction from Sargassum muticum brown seaweed using ultrasound-assisted technique.

Ultrasound assisted aqueous extraction of alginate from Sargassum muticum was proposed to minimize the use of chemicals, high temperatures and prolonged times, with comparable extraction yields to conventional acid/alkali procedures. The alginate, precipitated from the liquors obtained after ultrasound assisted extraction of fucoidan and phlorotannin fractions, and converted to alginic acid sodium...

Ultrasound guided angioplasty of arteriovenous fistulas for hemodialysis: Benefits and limitations.

Ultrasound-guided percutaneous angioplasty of arteriovenous fistulas (AVFs) makes it possible to avoid contrast agents and X-rays, to optimize the puncture site and to locate some stenoses on the fistulography, but is it really useful? Our objective was to report the results of our experience.

Forward-viewing echoendoscope versus standard echoendoscope for endoscopic ultrasound-guided tissue acquisition of solid lesions: a randomized, multicenter study.

 A forward-viewing linear (FVL) echoendoscope has been developed with the aim of overcoming some of the limitations of standard curved linear-array (CLA) echoendoscopes. There are no existing studies comparing the performance of the two echoendoscopes for endoscopic ultrasound-guided tissue acquisition (EUS-TA) of solid lesions other than subepithelial lesions.

Endoscopic ultrasound measurements for detection of residual disease after neoadjuvant chemoradiotherapy for esophageal cancer.

 Endoscopic ultrasound (EUS) measurements of residual thickness and residual area have been suggested to correlate with histopathological residual tumor after neoadjuvant chemoradiotherapy (nCRT) for esophageal cancer. This study assessed the predictive value of EUS-based measurements using tumor thickness and tumor area before nCRT, and residual thickness and residual area 6 and 12 weeks after ...
