BACKGROUND Previous studies have shown the feasibility of peripheral arterial ultrasound angioplasty. METHODS AND RESULTS In this report, we describe the use of percutaneous therapeutic ultrasound for coronary angioplasty. In vitro, 11 postmortem, atherosclerotically occluded coronary arteries were obtained to assess catheter-delivered ultrasound for arterial recanalization as well as for ass...

The feasibility and safety of magnetic resonance (MR) imaging-guided focused ultrasound surgery for uterine leiomyomas is reported. Sequential sonications were delivered to nine targets. Temperature-sensitive phase-difference MR imaging monitored the location of the focus and measured tissue temperature elevations, ensuring therapeutic dose. MR images and hysterectomy specimens were evaluated. ...

One of the many imaging uses of contrast enhanced ultrasound (CEUS) is studying a wide variety of kidney pathology, due to its ability to detect microvascular blood flow in real time without affecting renal function. CEUS enables dynamic assessment and quantification of microvascularisation up to capillary perfusion. The objective of this paper is to briefly refresh basic knowledge of ultrasoun...

We present a case of unexpectedly prolonged motor and sensory block following a successful single injection ultrasound - guided infraclavicular block with bupivacaine (0.25%) and dexamethasone (8 mg). ultrasound guidance and safety measurement such as injection of the local anaesthetic at a slow rate and verifying that usual resistance was felt throughout the injection, has been applied. It too...

Portability, safety, low cost and efficiency, together with the ability to accurately define pathology rapidly, have made ultrasound the primary imaging modality for evaluation of the scrotum, testis and paratesticular structures. These factors provide for timely diagnosis and treatment. Scrotal ultrasound is particularly helpful when a physical examination is inconclusive or a disease process ...

Background in Spain the skills of professionals of Emergency departament (ED) in the process of echocardiography have been discussed for decades. The current scientific evidence supports the use of echocardiography by the Emergency physicians (EP) in a resounding manner, due to its speed, agility and safety for the patient, by providing an early diagnosis of serious or potentially serious disea...

Background/introduction Magnetic Resonance guided Focused Ultrasound (MRgFUS) is a non-invasive, non-ionizing treatment producing thermal ablation using high intensity focused ultrasound and MR thermometry to denervate pain from bone metastases. A recent phase III study comparing MRgFUS to sham treatment for a painful bone metastasis allowed patients to be treated with concurrent chemotherapy a...

The development of a convex probe endobronchial ultrasound (CP-EBUS) videobronchoscope to allow real-time transbronchial needle aspiration (TBNA) has been a significant advance in minimally invasive lung cancer staging and diagnosis. Several recent studies have demonstrated CP-EBUS-TBNA to have recovery rivalling that of the current gold standard, cervical mediastinoscopy. These same studies ha...

For the anaesthetist performing an ultrasound guided regional anaesthetic (USGRA) procedure, the issue of where to place the local anaesthetic (LA) should now be crystal clear. After all, the gross anatomy of peripheral nerves has been thoroughly documented, and we have the knowledge obtained by over a decade of ultrasound imaging to add to our understanding of the appearance of nerves and thei...

Transrectal ultrasound-guided core prostate biopsy is a key event in the diagnosis of prostate cancer, transient side events such as local pain, haematuria, haematospermia, dysuria, and rectal bleeding are reported in a large number of patients. Antimicrobial agents lower the incidence of postbiopsy infectious complications. The timing and duration of the regimen and the route of administration...
