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.
