Anatomy, protocols, technique, technology, and scientific updates in ultrasonography.
Assessing muscle mass with ultrasound: what the evidence shows
Muscle thickness, echogenicity, and pennation angle as ultrasound parameters of body composition.
Ler artigo →Bedside lung ultrasound: the points every protocol shares
Lung sliding, B-lines, consolidation, and lung point — the common grammar behind the different thoracic POCUS protocols.
Ler artigo →Liver elastography: when it changes management
Liver stiffness as a noninvasive substitute for part of the information that biopsy used to provide alone.
Ler artigo →Artificial intelligence in ultrasonography: what already exists today
Automatic structure recognition, assisted measurements, and image acquisition support — without replacing medical judgment.
Ler artigo →Carotid Doppler: for whom, and how often
Clinical criteria that justify screening, and the difference between hemodynamically significant stenosis and an incidental finding.
Ler artigo →Transducers: how the choice changes what you can see
Frequency, shape, and penetration depth — the physics behind choosing the right transducer for each exam.
Ler artigo →Dermatologic ultrasound: what high frequency reveals about the skin
From characterizing skin tumors to monitoring scars, high-frequency ultrasound opens a window onto skin layers that clinical examination alone cannot reach.
Ler artigo →Peripheral nerve ultrasound: seeing compression before electromyography
Flattening, focal thickening, and loss of the fascicular pattern are signs high-resolution ultrasound identifies in compressive neuropathies, complementing clinical and electrophysiological assessment.
Ler artigo →Lipedema: what ultrasound adds to the clinical diagnosis
Ultrasound criteria for skin and subcutaneous thickness help differentiate lipedema from lymphedema and simple obesity — in a diagnosis that is still, for the most part, clinical.
Ler artigo →Filler complications: why ultrasound comes in before the scalpel
Identifying the type of filler, differentiating a granuloma from a nodule, and guiding hyaluronidase in real time — ultrasound has become the first tool when facing an aesthetic complication.
Ler artigo →Developmental dysplasia of the hip: Graf ultrasound is still the standard
More than four decades after Reinhard Graf described his method, ultrasound remains the central tool for screening hip dysplasia in newborns.
Ler artigo →Precocious puberty: what pelvic ultrasound adds to the diagnosis
Ovarian volume, uterine length, and the corpus-to-cervix ratio are pelvic parameters that help differentiate central precocious puberty from benign variants, complementing the GnRH stimulation test.
Ler artigo →Deep endometriosis: the IDEA consensus and the role of transvaginal ultrasound
A systematic pelvic assessment protocol has made transvaginal ultrasound the first-line investigation for deep endometriosis, when performed by a trained examiner.
Ler artigo →When musculoskeletal ultrasound adds information beyond MRI
In rotator cuff injuries and other dynamic pathologies, ultrasound can add relevant diagnostic information to the orthopedic surgeon's decision — even when MRI has already been performed.
Ler artigo →FAST: the targeted search for free fluid in the trauma patient
Indications, the four-window technique, and what the literature shows about the accuracy of the FAST protocol in abdominal and thoracic trauma triage.
Ler artigo →eFAST: when trauma ultrasound also looks at the chest
How the thoracic extension of FAST identifies pneumothorax and pleural effusion at the bedside, with the key ultrasound signs and the accuracy reported in the literature.
Ler artigo →Automation of ultrasound image acquisition with artificial intelligence
AI systems now optimize gain and depth, guide operators to standard planes, and even take over part of probe positioning, shortening the learning curve for point-of-care ultrasound.
Ler artigo →CEUS: Contrast-Enhanced Ultrasound for Perfusion Assessment and Lesion Characterization
Contrast-enhanced ultrasound (CEUS) uses microbubble agents to map perfusion in real time, aiding diagnosis of liver, renal and vascular lesions without radiation or nephrotoxicity.
Ler artigo →AI for detection, classification, and reporting: reducing inter-operator variability in ultrasound
Recent studies show that AI algorithms for detection, classification, and measurement in ultrasound can match or exceed average radiologist accuracy and consistently reduce inter-observer variability.
Ler artigo →Advanced Hepatic Ultrasound in the MASLD Workup: Steatosis, Fibrosis, Cirrhosis and Nodules
A practical, evidence-based guide to how B-mode ultrasound, quantitative attenuation techniques and elastography have transformed MASLD screening and staging.
Ler artigo →Artificial intelligence in musculoskeletal ultrasound: muscle injuries, peripheral nerves, and hyaluronic acid
How artificial intelligence is being studied to grade muscle injuries, automatically measure peripheral nerves, and support ultrasound-guided hyaluronic acid injections, and what the evidence already shows versus where it remains a promise.
Ler artigo →Shoulder ultrasound: how to perform and interpret it
A practical guide to positioning and scanning sequence so a relevant finding doesn't get missed during a shoulder exam.
Ler artigo →Rotator cuff: signs of tendinopathy on ultrasound
The findings that help distinguish tendinosis, partial tear and full-thickness tear of the rotator cuff — and the most common pitfalls in that assessment.
Ler artigo →Carpal tunnel syndrome: the role of median nerve ultrasound
How measuring the median nerve's cross-sectional area helps diagnose carpal tunnel syndrome, and where ultrasound fits alongside nerve conduction studies.
